How can one troubleshoot issues with using imagettfbbox() for text alignment in PHP as a beginner?

When using imagettfbbox() for text alignment in PHP, beginners may encounter issues with incorrect text positioning. To troubleshoot this, ensure that the font file path is correct and that the text alignment parameters are set properly. Additionally, check the coordinates used to position the text within the image to ensure accurate alignment. 

<?php

// Set the font file path
$font = 'arial.ttf';

// Get the bounding box for the text
$bbox = imagettfbbox(12, 0, $font, 'Sample Text');

// Calculate the text position within the image
$x = imagesx($image) / 2 - $bbox[4] / 2;
$y = imagesy($image) / 2 + $bbox[5] / 2;

// Draw the text on the image
imagettftext($image, 12, 0, $x, $y, $black, $font, 'Sample Text');

?>
