What is the significance of using proportional versal numbers in PHP when using imagettftext?

When using imagettftext in PHP to add text to an image, it is important to use proportional versal numbers to ensure that the text is displayed correctly and proportionally. This is because proportional versal numbers adjust the spacing between characters based on their width, resulting in a more visually pleasing layout. By using proportional versal numbers, you can avoid issues such as uneven spacing or overlapping characters in your text.

// Set the font size and font file
$font_size = 12;
$font_file = 'arial.ttf';

// Use proportional versal numbers for imagettftext
imagettftext($image, $font_size, 0, $x, $y, $text_color, $font_file, '1234567890');
