What potential pitfalls or errors may arise when trying to use the "imagettfbbox" function in PHP?

One potential pitfall when using the "imagettfbbox" function in PHP is that the function may return incorrect bounding box dimensions if the font file path is incorrect or the font file itself is not accessible. To solve this issue, ensure that the font file path is correct and that the font file has the proper permissions set. 

$fontFile = 'path/to/font.ttf';

// Check if the font file is accessible
if (!is_readable($fontFile)) {
    die('Font file is not accessible.');
}

// Use the imagettfbbox function with the correct font file path
$bbox = imagettfbbox($fontSize, 0, $fontFile, $text);
