What are the best practices for installing and utilizing Free Type libraries in PHP for functions like "imagettfbbox"?

When using functions like "imagettfbbox" in PHP to work with TrueType fonts, it is important to have the FreeType library installed and properly configured. This library allows PHP to interact with TrueType fonts and perform various text manipulation tasks. To ensure smooth operation, make sure the FreeType library is installed on your server and that PHP is configured to use it. 

// Check if FreeType library is installed
if (!function_exists('imagettfbbox')) {
    die('FreeType library is not installed on this server.');
}

// Use the imagettfbbox function to get the bounding box of a text string
$font = 'arial.ttf';
$size = 12;
$text = 'Hello, World!';
$bbox = imagettfbbox($size, 0, $font, $text);

// Display the bounding box dimensions
echo 'Text width: ' . ($bbox[2] - $bbox[0]) . ' pixels<br>';
echo 'Text height: ' . ($bbox[1] - $bbox[7]) . ' pixels';
