Question

I want to do the following

I want to create .php file (executed via cronjobs) that will paste this code $files[] = 'example.php';
to other php file (paste.php) but it has to find the lastest $files[] line like regex $files[] = '(AnythingHere)'; and after this line to paste the new line. It can have random number of pages so I have no way of knowing.

<?php

    if (!isset($php_file)) {

        $files[] = 'page1.php';

        $files[] = 'page2.php';

        $files[] = 'page3.php';

        $files[] = 'page4.php';

        $file = $files[ rand(0,count($files)) ];

I hope you guys understand what I want; can anyone help me out with this one?

Answer 1

if you have ONLY $file[] = ‘…’ in paste.php, you can simply append to the file:

$line = '$file[] = "pageX.php";' . PHP_EOL;
file_put_contents('paste.php', $line, FILE_APPEND);

of you want the last “page[]” enty.

$yourNewLine = '$file[] = "pageX.php";';  // this is an example. put your "line" prm here
$filename = 'paste.php';
$lines = file($filename);
$lines = array_reverse($lines)
$found = false;
$i = 0;
while ( ! $found )
{
    if ( strpos($lines[$i], '$files[] = ' === 0) ) 
    {
        $found = true;
        array_splice($lines, $i, 0, $yourNewLine.PHP_EOL);
    }   
    $i++;   
}
$lines = array_reverse($lines);
file_put_contents($filename, $lines);
