What are some best practices for accurately measuring the length of a string in PHP when using non-proportional fonts?

When using non-proportional fonts in PHP, accurately measuring the length of a string can be challenging because each character may have a different width. One way to address this issue is to use the `imagettfbbox()` function in PHP, which calculates the bounding box of a text using a TrueType font. By using this function, you can accurately measure the length of a string regardless of the font type. 

$text = "Hello, World!";
$font = "path/to/font.ttf";
$size = 12;

$bbox = imagettfbbox($size, 0, $font, $text);
$width = $bbox[2] - $bbox[0];

echo "The width of the string is: " . $width;
