[PHP] imagestring size?

programming
1

I am using PHP to create dynamic images, and I have done it all before but I have lost my old code and cant remember how to change the size of the text, my code is like this:


<?php
header("Content-type: image/png");
$post = "example"
$image = imagecreate(300, 60);
$black = imageColorAllocate($image, 80, 139, 197);
$text = imageColorAllocate($image, 255, 255, 255);
imagestring($image, 1, 5, 5, $post, $text);
imagepng($image);
imagedestroy($image);
?>

any help?
