What are some potential pitfalls when trying to change the font in an image generated by PHP?

One potential pitfall when trying to change the font in an image generated by PHP is not having the necessary font files installed on the server. To solve this issue, you can upload the font files to a directory on your server and specify the font path in your PHP code. 

// Specify the font file path
$fontFile = 'path/to/font.ttf';

// Load the font
$font = imageloadfont($fontFile);

// Set the font for the image
imagettftext($image, $size, $angle, $x, $y, $color, $font, $text);
