How can one debug and troubleshoot issues with displaying text in a custom font as an image in PHP?

Issue: One common issue when displaying text in a custom font as an image in PHP is that the font file path may not be correct or the font file itself may be corrupted. To troubleshoot this issue, ensure that the font file path is accurate and that the font file is valid. Additionally, check for any errors in the PHP code that may be preventing the font from being applied correctly. 

<?php
// Set the content type header to image/png
header('Content-Type: image/png');

// Load the font file
$font = 'path/to/custom-font.ttf';

// Create a blank image with a white background
$image = imagecreatetruecolor(400, 100);
$white = imagecolorallocate($image, 255, 255, 255);
imagefilledrectangle($image, 0, 0, 399, 99, $white);

// Set the text color and font
$textColor = imagecolorallocate($image, 0, 0, 0);
imagettftext($image, 20, 0, 10, 50, $textColor, $font, 'Custom Font Text');

// Output the image
imagepng($image);

// Free up memory
imagedestroy($image);
?>
