Symfony 1.4 deprecated function in php - symfony-1.4

Question

Anyone know what is this error? I need help with this Deprecated: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead in C:\xampp\htdocs\sfprojects\jobeet\lib\vendor\symfony\lib\response\sfWebResponse.class.php on line 409. I'm using xampp 1.8.3 and symfony 1.4.
I couldn't get to step forward because of this a weeke a go :'(. Any help will be appreciated. Thank you.

Answer 1

In myproject/lib/vendor/symfony/lib/response/sfWebResponse.class.php on line 409
protected function normalizeHeaderName($name)
{
// return preg_replace('/\-(.)/e', "'-'.strtoupper('\\1')", strtr(ucfirst(strtolower($name)), '_', '-'));
return preg_replace_callback(
'/\-(.)/',
function ($matches) {
return '-'.strtoupper($matches[1]);
},
strtr(ucfirst(strtolower($name)), '_', '-')
);
}
FIX for pregtr method in /lib/vendor/symfony/lib/util/sfToolkit.class.php on line 360
public static function pregtr($search, $replacePairs){
// return preg_replace(array_keys($replacePairs), array_values($replacePairs), $search);
foreach($replacePairs as $pattern => $replacement)
{
if (preg_match('/(.*)e$/', $pattern, $matches))
{
$pattern = $matches[1];
$search = preg_replace_callback($pattern, function ($matches) use ($replacement) {
preg_match("/('::'\.)?([a-z]*)\('\\\\([0-9]{1})'\)/", $replacement, $match);
return ($match[1]==''?'':'::').call_user_func($match[2], $matches[$match[3]]);
}, $search);
}
else
{
$search = preg_replace($pattern, $replacement, $search);
}
}
return $search;
}
I've combined two answers from duplicate thread Symfony 1.4 using deprecated functions in php 5.5 answered by mika and xtech (up-vote them please)
It also affects /lib/form/addon/sfFormObject.class.php on line 281
protected function camelize($text)
{
//return preg_replace(array('#/(.?)#e', '/(^|_|-)+(.)/e'), array("'::'.strtoupper('\\1')", "strtoupper('\\2')"), $text); //ORIGINAL
return strtr(ucwords(strtr($text, array('/' => ':: ', '_' => ' ', '-' => ' '))), array(' ' => ''));
}

Tested, all changes look good

Answer 3

as this function is called in several files in sf 1.4, here are all changes that i made in my projects (based on different sources, including sf 1.4 forks):
lib/vendor/symfony/lib/command/sfCommandManager.class.php
## -108,7 +108,9 ## class sfCommandManager
else if (!is_array($arguments))
{
// hack to split arguments with spaces : --test="with some spaces"
- $arguments = preg_replace('/(\'|")(.+?)\\1/e', "str_replace(' ', '=PLACEHOLDER=', '\\2')", $arguments);
+ $arguments = preg_replace_callback('/(\'|")(.+?)\\1/', function ($match) {
+ return str_replace(' ', '=PLACEHOLDER=', $match[2]);
+ }, $arguments);
$arguments = preg_split('/\s+/', $arguments);
$arguments = str_replace('=PLACEHOLDER=', ' ', $arguments);
}

}

}

}

}
lib/vendor/symfony/lib/util/sfInflector.class.php
## -27,11 +27,7 ## class sfInflector
public static function camelize($lower_case_and_underscored_word)
{

- '/(^|_|-)+(.)/e' => "strtoupper('\\2')"));
-
- return $tmp;
+ return strtr(ucwords(strtr($lower_case_and_underscored_word, array('/' => ':: ', '_' => ' ', '-' => ' '))), array(' ' => ''));
}
beside, here is the fix for the E_NOTICE lib/vendor/symfony/lib/plugins/sfDoctrinePlugin/lib/vendor/doctrine/Doctrine/Query/Abstract.php:
lib/vendor/symfony/lib/plugins/sfDoctrinePlugin/lib/vendor/doctrine/Doctrine/Query/Abstract.php
## -1149,7 +1149,16 ## abstract class Doctrine_Query_Abstract
$copy->free();
if ($componentsBefore !== $componentsAfter) {
- return array_diff($componentsAfter, $componentsBefore);
+ $diff = array();
+
+ foreach($componentsAfter as $key => $val) {
+ if(!isset($componentsBefore[$key])) {
+ $diff[$key] = $val;
+ } elseif(is_array($componentsBefore[$key]) && !is_array($val)) {
+ $diff[$key] = $val;
+ }
+ }
+ return $diff;
} else {
return $componentsAfter;
}

You can unset the E_DEPRECATED flag in every application settings.yml :
dev:
.settings:
error_reporting: <?php echo ((E_ALL | E_STRICT) ^ E_DEPRECATED)."\n" ?>
