Are there any best practices or recommended methods for achieving a text contour effect in PHP?

To achieve a text contour effect in PHP, one common method is to create two text layers with different colors and slightly offset one layer behind the other to create a shadow effect. This can be done using the imagettftext() function in PHP to draw text on an image. 

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

// Set background color
$bg_color = imagecolorallocate($image, 255, 255, 255);
imagefill($image, 0, 0, $bg_color);

// Set text colors
$text_color = imagecolorallocate($image, 0, 0, 0);
$contour_color = imagecolorallocate($image, 150, 150, 150);

// Set font file and text
$font = 'arial.ttf';
$text = 'Hello World!';

// Draw contour text
imagettftext($image, 30, 0, 50, 100, $contour_color, $font, $text);
imagettftext($image, 30, 0, 48, 98, $contour_color, $font, $text);

// Draw main text
imagettftext($image, 30, 0, 50, 100, $text_color, $font, $text);

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

// Free up memory
imagedestroy($image);
