Creating multiple images with php

Question

So I have a file named "names.txt" with multiple lines. Each line contains one name. I also have one mockup image named "participant.jpg"

And here it`s my code:

<?php
$handle = fopen("names.txt", "r");

function create_img($line)
{
    $im = imagecreatefromjpeg("./images/participant.jpg");
    $textcolor = imagecolorallocate($im, 0, 0, 0);

    // Write the string at the top left
    imagettftext($im, 50, 0, 80, 640, $textcolor, 'nexa.ttf', $line);

    imagejpeg($im, './uploads/' . $line . '.jpg');
    imagedestroy($im);
}

if ($handle) {
    while (($line = fgets($handle)) !== false) {
        create_img($line);
    }
} else {
    die('Cannot open file..');
}
?>

So for every new line I want to create a specific photo and "upload" it to my uploads folder.

It only creates the image for the last line and for the rest it returns me this error:

Warning: imagejpeg() [<a href='function.imagejpeg'>function.imagejpeg</a>]: Unable to open './uploads/Botond.jpg' for writing: Invalid argument in C:\lab\ccc-badges\badges.php on line 12

This is some $line outputs

yeah, use imagejpeg($im, './uploads/' . trim($line) . '.jpg'); when writing in a file — el Dude

That problem because the trailing newline of each fgets(), except the last line.

use imagejpeg($im, './uploads/' . trim($line) . '.jpg'); when writing in a file.
