What are potential pitfalls when using imagettfbbox on a Linux server compared to a Windows server?

When using imagettfbbox on a Linux server compared to a Windows server, one potential pitfall is that the font file paths may need to be specified differently due to differences in file system paths between the two operating systems. To solve this issue, it is recommended to use absolute file paths when specifying the font file location in the imagettfbbox function.

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

// Get the bounding box for text using imagettfbbox with absolute file path
$bbox = imagettfbbox($fontSize, 0, $fontFile, $text);
