How can the use of absolute paths for font files in PHP image generation scripts help prevent errors on different servers?

When using relative paths for font files in PHP image generation scripts, errors can occur on different servers due to variations in file structures. By using absolute paths, we can ensure that the script always references the correct location of the font files regardless of the server environment. This helps prevent errors and ensures consistent rendering of text in the generated images.

// Absolute path to the font file
$fontFile = '/var/www/html/fonts/myfont.ttf';

// Use the absolute path in the script
$font = imageloadfont($fontFile);
