PHPExcel example of use - phpexcel

Question

I am trying to use PHPExcel lib. I already read some the API, but still didn't figure how to use it correctly.
I'm trying to convert an array, to an excel table.
If I have:
$Array = array(
array('key1' => 'Content1', 'key2' => 'Content2'),
array('key1' => 'Content3', 'key2' => 'Content4')
);
So the output in the excel file will be:
key1 key2
Content1 Content2
Content3 Content4
key1 and key2 as headings.
Can you help? Thank you

Answer 2

Here is my code what I did it ...but the scenario here is little different, here the input is the excel file whereas the output is array of array in 'key' => 'value' pairs (as in your case it is vice versa) which is not much of a solution but though it might help you get going.
<?php
include './PHPExcel/IOFactory.php';
$objPHPExcel = PHPExcel_IOFactory::load('campaign.xlsx');
foreach ($objPHPExcel->getWorksheetIterator() as $worksheet) {
$highestColumn = $worksheet->getHighestDataColumn();
//Getting highest column with data
$highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);
//Getting highest row with data
$highestRow = $worksheet->getHighestRow();
$header = [];
//For saving all heading from Excel file.
for( $i = 0 ; $i <= $highestColumnIndex ; $i++)
{
$cell = $worksheet->getCellByColumnAndRow($i,1);
$val = $cell->getValue();
$header[] = $val;
}
$completeArray = [];
$value = [];
//For saving header and value pairs in a array
for ($row = 2; $row <= $highestRow; ++ $row) {
for ($col = 0; $col < $highestColumnIndex; ++ $col) {
$cell = $worksheet->getCellByColumnAndRow($col, $row);
$val = $cell->getValue();
$value[$header[$col]] = $val;
}
//Inserting that array...
$completeArray[] = $value;
}
}
echo '<pre>';
print_r($completeArray);
echo '</pre>';
So,in your case instead of using all get methods such as getCellByColumnAndRow as in my example you can use
setCellValueByColumnAndRow($column, $row, $value);
