How can PHP developers optimize the rendering of text as images to avoid layout discrepancies?

When rendering text as images in PHP, developers can optimize the process by ensuring consistent font rendering across different environments. One way to achieve this is by using the GD library to render text onto images, specifying the font file path and size explicitly. This helps avoid layout discrepancies that may occur due to differences in font rendering between servers. 

<?php
// Set the font file path
$fontFile = 'path/to/font.ttf';

// Set the font size
$fontSize = 12;

// Create a new image with specified width and height
$image = imagecreatetruecolor(200, 50);

// Set the text color
$textColor = imagecolorallocate($image, 0, 0, 0);

// Set the background color
$bgColor = imagecolorallocate($image, 255, 255, 255);

// Fill the image with the background color
imagefilledrectangle($image, 0, 0, 200, 50, $bgColor);

// Write the text onto the image
imagettftext($image, $fontSize, 0, 10, 30, $textColor, $fontFile, 'Hello, World!');

// Output the image
header('Content-Type: image/png');
imagepng($image);

// Free up memory
imagedestroy($image);
?>
