How can I generate a graphic with different text colors and line breaks using PHP functions like Imagestring and Imagettftxt?

To generate a graphic with different text colors and line breaks using PHP functions like Imagestring and Imagettftxt, you can use the GD library functions to create an image, set the text color, and position text with line breaks. You can achieve this by using functions like imagecolorallocate() to set text colors, Imagestring() to draw text in a specific color, and Imagettftxt() to draw TrueType text with line breaks. 

<?php
// Create a blank image
$image = imagecreatetruecolor(400, 200);

// Set text colors
$black = imagecolorallocate($image, 0, 0, 0);
$red = imagecolorallocate($image, 255, 0, 0);

// Set text with line breaks
$text = "Hello\nWorld";
imagettftext($image, 20, 0, 10, 50, $black, 'arial.ttf', $text);

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

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