PHP Write to file not writing to file

Question

I want my php file to write some text to a text file that I have created but nothing is being written to it.

Here is the code:

<?php
    error_reporting(E_ALL);
    ini_set('display_errors', '1');

    if (isset($_POST['comment']))
    {
        $comment = $_POST['comment'];

        $myFile = "testFile.txt";
        $fh = fopen($myFile, 'w') or die("can't open file");
        $stringData = $comment;
        fwrite($fh, $stringData);
        fclose($fh);
    }
    else
    {
        $comment = 'no comment';

        $myFile = "testFile.txt";
        $fh = fopen($myFile, 'w') or die("can't open file");
        $stringData = $comment;
        fwrite($fh, $stringData);
        fclose($fh);
    }
?>

Check the file permissions.

Try changing permission if that was the issue:

chmod("testFile.txt", 0644);
