What are the best practices for handling color allocation and text rendering in PHP when working with image manipulation functions?

When working with image manipulation functions in PHP, it is important to handle color allocation efficiently and ensure clear text rendering for optimal results. To achieve this, it is recommended to use the imagecolorallocate() function to allocate colors in images and use imagettftext() function for text rendering with TrueType fonts.

// Allocate colors in the image
$black = imagecolorallocate($image, 0, 0, 0);
$white = imagecolorallocate($image, 255, 255, 255);

// Render text on the image
imagettftext($image, $font_size, 0, $x, $y, $black, $font_path, $text);
