What are the best practices for maintaining consistent positioning of text elements when using ImageTTFText in PHP?

When using ImageTTFText in PHP to add text to images, it is important to maintain consistent positioning of text elements to ensure a professional and polished appearance. To achieve this, you can calculate the width and height of the text using the imagettfbbox function and then adjust the x and y coordinates accordingly. Additionally, setting a fixed font size and using a monospace font can help with alignment. 

// Set the font size and font file
$font_size = 20;
$font_file = 'arial.ttf';

// Get the bounding box of the text
$text = 'Hello, World!';
$bbox = imagettfbbox($font_size, 0, $font_file, $text);
$width = $bbox[2] - $bbox[0];
$height = $bbox[1] - $bbox[7];

// Calculate the x and y coordinates for positioning the text
$x = (imagesx($image) - $width) / 2;
$y = (imagesy($image) + $height) / 2;

// Add the text to the image
imagettftext($image, $font_size, 0, $x, $y, $black, $font_file, $text);
