How can you extract the first letter of a text in PHP and convert it into an image?

To extract the first letter of a text in PHP and convert it into an image, you can use the GD library to create an image with the letter as text. First, extract the first letter of the text using substr(). Then, create a new image using imagecreate() and add the letter as text using imagettftext(). Finally, output the image using imagepng(). 

$text = "Hello World";
$firstLetter = strtoupper(substr($text, 0, 1));

$width = 100;
$height = 100;
$image = imagecreate($width, $height);

$background = imagecolorallocate($image, 255, 255, 255);
$textColor = imagecolorallocate($image, 0, 0, 0);

$font = 'arial.ttf';
imagettftext($image, 40, 0, 30, 60, $textColor, $font, $firstLetter);

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