In PHP image generation scripts, what are the potential pitfalls related to font file paths and how can they be mitigated?

When generating images with PHP, one common pitfall is specifying the correct path to the font file. To mitigate this issue, it's important to use absolute paths or relative paths that are relative to the script's location. This ensures that the script can always locate the font file regardless of where it is executed.

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

// Or use a relative path that is relative to the script's location
$fontFile = __DIR__ . "/fonts/font.ttf";
