Answer : varchar sort

Oh sorry, I didn't see some of your requirements, here the correct code:

                       
             <?php 
$source="input.txt";  
$data = '<?php'."\n"."require_once('../file.php');"."\n".'echo"hello";'."\n";
$data .=file_get_contents($source);  
$data .='echo "end";'."\n".'?>';
$outputFile="output.php";   
file_put_contents($outputFile, $data, FILE_APPEND);  
?>
