I am doing a tutorial and am getting this error:
Fatal error: Class 'MySQLi' not found (LONG URL) on line 8
The code on line 8 is:
$mysqli = new MySQLi($db_server, $db_user, $db_pass, $db_name);
I saw online someone said to see if it was turned on in my phpinfo(), but there wasn't anything listed in there under for "mysqli".
Also, I am running PHP version 5.2.5
Sounds like you just need to install MySQLi.
If you think you've done that and still have a problem, please post your operating system and anything else that might help diagnose it further.
You can check if the mysqli libraries are present by executing this code:
if (!function_exists('mysqli_init') && !extension_loaded('mysqli')) {
echo 'We don\'t have mysqli!!!';
} else {
echo 'Phew we have it!';
}
If you are on Ubuntu, run:
sudo apt-get install php-mysqlnd
And don't forget to restart the php service after this (Apache or php-fpm depends on the setup).
If you're calling "new mysqli(..)" from within a class that is namespaced, you might see a similar error Fatal error: Class 'foo\bar\mysqli' not found in. The way to fix this is to explicitly set it to the root namespace with a preceding backslash like so:
<?php
$mysqli = new \MySQLi($db_server, $db_user, $db_pass, $db_name);
In addition to uncommenting the php_mysqli.dll extension in php.ini, also uncomment the extension_dir directive in php.ini and specify your location:
extension_dir = "C:\software\php\dist\ext"
This made it work for me.
If you are on Docker...
Inside php-container RUN:
#docker-php-ext-install mysqli
#apachectl restart
My OS is Ubuntu. I solved this problem by using:
sudo apt-get install php5-mysql
How to Enable mysqli in php.ini
Edit/uncomment by removing ';'(colon) the following config in php.ini:
1st (uncomment and add config):
include_path = "C:\php\includes"
2nd (uncomment):
extension_dir = "ext"
3rd (uncomment and edit config):
extension=C:/PHP/ext/php_mysql.dll
extension=C:/PHP/ext/php_mysqli.dll
Restart the IIS server
Make sure that mysql is running on the system.
How to load php.ini file
Rename any one of the file php.ini-production/php.ini-development to php.ini from C:\PHP(note now the extention will be ini i.e "php.ini").
After renaming to php.ini file restart server
See the changes in http://localhost/phpinfo.php
For anyone using docker, I ran into this issue, and resolved it by using my own Dockerfile instead of the php:fpm image:
FROM php:fpm
RUN docker-php-ext-install mysqli
Seems like problem with your installation.
Have you installed MySQLi?
Have you activated it in php.ini?
Restarted Apache and/or PHP-FPM?
http://www.php.net/manual/en/mysqli.installation.php
Open your PHP folder.
Find php.ini-development and open it.
Find ;extension=mysqli
delete the ; symbol
save file and change the file extension from php.ini-development to php.ini
Restart the server and test the code:
if (!function_exists('mysqli_init') && !extension_loaded('mysqli')) {
echo 'We don\'t have mysqli!!!';
} else {
echo 'mysqli is installed';
}
if it not working, change both extension_dir in php.ini from "ext" to "c:\php\ext"
and extension=mysqli to extension=php_mysqli.dll then test again
Remember to reset the server every time you test
The PHP zip includes most of the commonly used extensions (*.dll on windows such as php_mysqli.dll) under the \ext directory, however they are not enabled by default. You might be getting this Fatal Error when trying to use MySQLi:
( ! ) Fatal error: Uncaught Error: Class 'mysqli' not found in C:\myProject\ class.Database.php on line 24
To enable extensions, open php.ini (you might need to first copy php.ini-development as php.ini), and un-comment (or add) these two lines:
extension_dir = "ext"
And any particular extensions you are getting Fatal Errors for, i.e. for mysqli:
extension=mysqli
On a fresh install of PHP, remove ; before extension_dir in php.ini.
I thought I might help anybody with the same problem using Namesco servers.
I have been trying to fix this problem after moving a database from my local server on home pc to namesco. They would not assist they said it was a coding issue.
However, it was simple to fix from their CPANEl LINUX hosting
interface.
Click on php.
then click on php modules and from their list of preinstalled modules just click the box for mysqli.
Then click save. (No need to change code if it worked(s) on another server.)
Unfortunately, their support articles were a waste of time. After reading this I went to admin interface with a new determination.
Some distributions (such as Gentoo) support multiple installations of PHP, and you have to make sure you're using one with mysqli installed and enabled.
On Gentoo, I had installed a new PHP (with the mysqli USE flag enabled), but I needed to activate the new version of PHP (since the old one must have been missing mysqli):
# eselect php list apache2
[1] php5.3 *
[2] php5.5
# eselect php set apache2 2
You have to run `/etc/init.d/apache2 restart' for the changes to take effect
# /etc/init.d/apache2 restart
I checked all above and it didn't work for me,
There are some steps I found.
I used PHP Version 5.5.9-1ubuntu4.17 on Ubuntu 14.04
First check the folder
#ls /etc/php5/mods-available/
json.ini mcrypt.ini mysqli.ini mysql.ini mysqlnd.ini opcache.ini pdo.ini pdo_mysql.ini readline.ini xcache.ini
If it did not contain mysqli.ini, read other answer for installing it,
Open php.ini find extension_dir
In my case , I must set extension_dir = /usr/lib/php5/20121212
And restart apache2 : /ect/init.d/apache2 restart
on ubuntu:
sudo apt-get install php-mysql
sudo service apache2 restart
on Debian 10
apt install php-mysql
/etc/init.d/apache2 restart
I found a solution for this problem after a long analysing procedure.
After properly testing my php installation with the command line features I found out that the php is working well and could work with the mysql database. Btw. you can run code-files with php code with the command php -f filename.php
So I realized, it must something be wrong with the Apache.
I made a file with just the phpinfo() function inside.
Here I saw, that in the line
Loaded Configuration File
my config file was not loaded, instead there was mentioned (none).
Finally I found within the Apache configuration the entry
<IfModule php5_module>
PHPINIDir "C:/xampp/php"
</IfModule>
But I've installed the PHP 7 and so the Apache could not load the php.ini file because there was no entry for that.
I added
<IfModule php7_module>
PHPINIDir "C:/xampp/php"
</IfModule>
and after restart Apache all works well.
These code blocks above I found in my httpd-xampp.conf file. May it is somewhere else at your configuration.
In the same file I had changed before the settings for the php 7 as replacement for the php 5 version.
#
# PHP-Module setup
#
#LoadFile "C:/xampp/php/php5ts.dll"
#LoadModule php5_module "C:/xampp/php/php5apache2_4.dll"
LoadFile "C:/xampp/php/php7ts.dll"
LoadModule php7_module "C:/xampp/php/php7apache2_4.dll"
As you can see I have the xampp package installed but this problem was just on the Apache side.
install
phpXX-extension by PHP.
In my FreeBSD's case:
pkg install php74-extensions
I'm using xampp and my problem was fixed once i rename:
extension_dir = "ext"
to
extension_dir = "C:\xampp\php\ext"
PS: Don't forget to restart apache after making this change!
In php.ini :
extension_dir ="c:/wamp64/bin/php/php7.4.9/ext/"
Make sure the PHP version is correct.
All you have to do is go to the php.ini file and on line 926 (depending on version) delete #. It should look like this:
;extension=ldap
;extension=mbstring
;extension=exif
extension=mysqli
;extension=oci8_12c
;extension=odbc
Save the file and open console (cmd) as administrator. Go to the path Apache24 / bin and enter httpd -k restart. This command will restart your server. After that, refresh the page and everything should work.
When I tried my PHP web app it was giving me the same error.
By googling I found out the MySQL plugin for the PHP server was missing with my installation. I am using Ubuntu, so when I tried MySQL plugin for PHP I found out 2 are there,
php-mysql and php<version>-mysql
I issued command - php --version in my terminal, I was having php7.4,
again I issued apt install php7.4-mysql
It worked.
This issue can be also caused by the .htaccess file misconfiguration.
I am trying to install Symfony on my Mac. Using the Terminal I have carried out the first three lines of the guide:
sudo curl -LsS https://symfony.com/installer -o /usr/local/bin/symfony
sudo chmod a+x /usr/local/bin/symfony
symfony new my_project_name
This started to download the files and then I got this message:
Preparing project...
Warning: date(): It is not safe to rely on the system's timezone settings. You are required to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in phar:///usr/local/bin/symfony/src/Symfony/Installer/NewCommand.php on line 283
✕ Symfony 3.2.8 was successfully installed but your system doesn't meet its
technical requirements! Fix the following issues before executing
your Symfony application:
date.timezone setting must be set
Set the "date.timezone" setting in php.ini* (like Europe/Paris).
I've tried to find the php.ini file but it doesn't appear in a search.
So, where can I find it and if it is a hidden file - how do I unhide it?
Thanks
You should find it in /private/etc if it exists, otherwise:
sudo cp /private/etc/php.ini.default /private/etc/php.ini
https://stackoverflow.com/a/9343210/7888593
Or to answer your question,in terminal.app type
php --ini
In your Terminal just type the following:
php -i | grep ini
There you can see which php.ini is used (including the full path)
Your webserver might use a different ini but the installation should work.
You can find it also by adding
<?php phpinfo(); ?>
anywhere in a php file
This way you are sure to get the php.ini used by your project and not by your computer
I followed the Software Collections Quick Start and I now have Python 3.5 installed. How can I make it always enabled in my ~/.bashrc, so that I do not have to enable it manually with scl enable rh-python35 bash?
Use the scl_source feature.
Create a new file in /etc/profile.d/ to enable your collection automatically on start up:
$ cat /etc/profile.d/enablepython35.sh
#!/bin/bash
source scl_source enable python35
See How can I make a Red Hat Software Collection persist after a reboot/logout? for background and details.
This answer would be helpful to those who have limited auth access on the server.
I had a similar problem for python3.5 in HostGator's shared hosting. Python3.5 had to be enabled every single damn time after login. Here are my 10 steps for the resolution:
Enable the python through scl script python_enable_3.5 or scl enable rh-python35 bash.
Verify that it's enabled by executing python3.5 --version. This should give you your python version.
Execute which python3.5 to get its path. In my case, it was /opt/rh/rh-python35/root/usr/bin/python3.5. You can use this path to get the version again (just to verify that this path is working for you.)
Awesome, now please exit out of the current shell of scl.
Now, lets get the version again through this complete python3.5 path /opt/rh/rh-python35/root/usr/bin/python3.5 --version.
It won't give you the version but an error. In my case, it was
/opt/rh/rh-python35/root/usr/bin/python3.5: error while loading shared libraries: libpython3.5m.so.rh-python35-1.0: cannot open shared object file: No such file or directory
As mentioned in Tamas' answer, we gotta find that so file. locate doesn't work in shared hosting and you can't install that too.
Use the following command to find where that file is located:
find /opt/rh/rh-python35 -name "libpython3.5m.so.rh-python35-1.0"
Above command would print the complete path (second line) of the file once located. In my case, output was
find: `/opt/rh/rh-python35/root/root': Permission denied
/opt/rh/rh-python35/root/usr/lib64/libpython3.5m.so.rh-python35-1.0
Here is the complete command for the python3.5 to work in such shared hosting which would give the version,
LD_LIBRARY_PATH=/opt/rh/rh-python35/root/usr/lib64 /opt/rh/rh-python35/root/usr/bin/python3.5 --version
Finally, for shorthand, append the following alias in your ~/.bashrc
alias python351='LD_LIBRARY_PATH=/opt/rh/rh-python35/root/usr/lib64 /opt/rh/rh-python35/root/usr/bin/python3.5'
For verification, reload the .bashrc by source ~/.bashrc and execute python351 --version.
Well, there you go, now whenever you login again, you have got python351 to welcome you.
This is not just limited to python3.5, but can be helpful in case of other scl installed softwares.
I am using PHPStorm 8.0.1.
I am working on a Symfony Project which runs on an nginx webserver on a debian system.
I have set up Automatic Deployment correctly and everything works very well, except of renaming the remote files.
PHPStorm fails with the message: "Failed to rename file 'filename.extension' to 'filename.extension': could not determine if file 'path to file' is writeable. (Could not get the groups id of the current user (error code: 1))
Can Anybody here point me in the direction on how to solve this error?
I had exactly the same problem. Reason: chroot enabled (thanks BloodandDeath for comment). In my Hestia panel settings, I just switched the SSH user setting from nologin to bash, after which PHPStorm started renaming files without error. By the way, everything worked well in Filezilla without changing the settings, which suggests a bug in PHPStorm ...
I am trying to install Symfony2 on my localhost (MAMP), I followed the installation instruction available on the official Symfony site.
First i installed the composer and moved it to a specific directory.
$ curl -sS https://getcomposer.org/installer | php
$ sudo mv composer.phar /usr/local/bin/composer
I then executed the installation command:
composer create-project symfony/framework-standard-edition *my-project-path-in-MAMP-htdocs*/ "2.5.*"
During Installation process I am prompted with a question if I want to instal Acme bundle I type 'y' to confirm that I do want to instal this Bundle....
But during the installation of that Bundle I get this Error message:
Warning: date_default_timezone_get(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Europe/London' for 'BST/1.0/DST' instead in /Applications/MAMP/htdocs/Symfony/project1/vendor/monolog/monolog/src/Monolog/Logger.php line 233
Can anyone help me or suggest a solution...?
You need to set the parameter date.timezone in your php.ini for every valid timezone and after that do not forget to restart Apache, try if this solve your issue
Procedure
I'm not use LAMP environment since I work with Linux but things should be the same as Mac is *nix. Anyway, you should find where php.ini file is under your directory structure (again I not use MacOS so I can't help here) and open it with any text editor or console text editor (personally I prefer this one) and find for that string date.timezone when you found it just uncomment that line by removing the ; symbol at front of the string and add a valid timezone lets said for example Europe/Amsterdam then you should have something like:
date.timezone = Europe/Amsterdam
That's all, restart your LAMP environment if you use any stack application or just restart Apache service, that will be all
