示例 #1 imagegrabscreen() example
This example demonstrates how to take a screenshot of the current screen and save it as a png image.
<?php
$im = imagegrabscreen();
imagepng($im, "myscreenshot.png");
imagedestroy($im);
?>If you have multiple displays set up, this function will only grab the primary display; not all of them like you would with the 'Print Screen' key.
Also, this should be pretty obvious but I'll mention it anyway, if you're running GPU-intensive applications (not CPU), calling this function will cause quite some significant lag to your machine and server response until the request is complete.
