What is the significance of determining the pixel width of a word in PHP?

Determining the pixel width of a word in PHP is significant for tasks such as text wrapping, alignment, and layout design in web development. This allows developers to accurately calculate the size of text elements on a webpage and ensure proper spacing and formatting. One way to achieve this is by using the `imagettfbbox()` function in PHP, which calculates the bounding box of a text string using a TrueType font. 

<?php
$text = "Hello";
$font_size = 12;
$font = "arial.ttf"; //path to your TrueType font file

$bbox = imagettfbbox($font_size, 0, $font, $text);
$width = $bbox[4] - $bbox[0]; //calculate pixel width of the word

echo "The pixel width of the word '$text' is: $width pixels.";
?>
