What are some potential solutions or resources for adding a contour to text in PHP images?

Adding a contour to text in PHP images can be achieved by overlaying multiple layers of text with slight offsets to create a shadow effect. One way to do this is by drawing the text in a darker color slightly below and to the right of the original text. This creates the illusion of a contour or shadow around the text. 

// Create a new image
$image = imagecreate(200, 100);

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

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

// Draw the main text
imagettftext($image, 20, 0, 10, 50, $text_color, 'arial.ttf', 'Hello World');

// Draw the contour text
imagettftext($image, 20, 0, 12, 52, $bg_color, 'arial.ttf', 'Hello World');

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

// Free up memory
imagedestroy($image);
