How can the width of text be calculated in pixels in PHP?

To calculate the width of text in pixels in PHP, you can use the `imagettfbbox()` function from the GD library. This function calculates the bounding box of a text using a TrueType font and returns an array containing the coordinates of the box. By subtracting the x-coordinate of the starting point from the x-coordinate of the ending point, you can determine the width of the text in pixels. 

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

$bbox = imagettfbbox($font_size, 0, $font_path, $text);
$text_width = $bbox[2] - $bbox[0];

echo "The width of the text is: " . $text_width . " pixels";
