What are the potential pitfalls of creating an image with PHP to measure text width?

One potential pitfall of creating an image with PHP to measure text width is that the rendered text may not accurately reflect the actual width when displayed on different devices or browsers due to variations in font rendering. To solve this issue, you can use the `imagettfbbox()` function in PHP to calculate the bounding box of the text and accurately measure its width. 

$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 "Text width: " . $text_width;
