Even though I literally copied and pasted the code below directly from the php.net manual on gd and image functions, I'm getting a syntax error message "unexpected t_variable" when I try to run the code. The culprit, according to the error message, is line 6 here:
$gd = imagecreatetruecolor($x, $y);
But there are NOT any missing semicolons or brackets in that line or before it. So why won't this code run for me? Here's the entire code:
<?php
$x = 200;
$y = 200;
$gd = imagecreatetruecolor($x, $y);
$corners[0] = array('x' => 100, 'y' => 10);
$corners[1] = array('x' => 0, 'y' => 190);
$corners[2] = array('x' => 200, 'y' => 190);
$red = imagecolorallocate($gd, 255, 0, 0);
for ($i = 0; $i < 100000; $i++) {
imagesetpixel($gd, round($x),round($y), $red);
$a = rand(0, 2);
$x = ($x + $corners[$a]['x']) / 2;
$y = ($y + $corners[$a]['y']) / 2;
}
header('Content-Type: image/png');
imagepng($gd);
?>
Here is a link to that page (scroll down a tiny bit) if it helps:

BTW, my server is gd enabled. Maybe that version is too new? Somewhere in the back of my mind I remember that a newer version might exclude some functionality? I don't know...
