What are best practices for setting the font path for imagettfbbox function in PHP on different operating systems?

When using the imagettfbbox function in PHP to calculate the bounding box of a TrueType font, it is important to set the correct font path so that the function can locate the font file. Since the font path can vary depending on the operating system, it is recommended to use the built-in function `dirname(__FILE__)` to dynamically set the font path based on the current file's directory. This ensures that the font file can be found regardless of the operating system. 

// Set the font path dynamically based on the current file's directory
$font_path = dirname(__FILE__) . '/fonts/arial.ttf';

// Use the font path when calling imagettfbbox function
$bbox = imagettfbbox($font_size, 0, $font_path, $text);
