What are the possible values for the second parameter in the ImageString function in PHP and how do they affect the font size?

The possible values for the second parameter in the ImageString function in PHP are integers ranging from 1 to 5. These values represent different font sizes, with 1 being the smallest and 5 being the largest. By choosing the appropriate value for the second parameter, you can control the font size of the text displayed using the ImageString function.

// Example of using ImageString function with different font sizes
$im = imagecreate(200, 50);
$black = imagecolorallocate($im, 0, 0, 0);
$font_size = 5; // Change this value from 1 to 5 for different font sizes
$text = "Hello World";
imagestring($im, $font_size, 10, 10, $text, $black);
header('Content-Type: image/png');
imagepng($im);
imagedestroy($im);
