Are there any best practices for ensuring text is centered accurately when using ImageTTFText() in PHP?

When using ImageTTFText() in PHP to add text to an image, ensuring that the text is centered accurately can be achieved by calculating the position based on the text size and image dimensions. One way to do this is by using the imagettfbbox() function to get the bounding box of the text and then calculating the x-coordinate for centering. By using this method, you can ensure that the text is centered correctly on the image. 

// Set the text to be added to the image
$text = "Centered Text";

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

// Get the image dimensions
$image_width = imagesx($image);
$image_height = imagesy($image);

// Get the bounding box of the text
$text_box = imagettfbbox($font_size, 0, $font_file, $text);

// Calculate the x-coordinate for centering the text
$text_width = $text_box[2] - $text_box[0];
$x = ($image_width - $text_width) / 2;

// Add the text to the image
imagettftext($image, $font_size, 0, $x, $image_height / 2, $text_color, $font_file, $text);
