I read them, but the fact of me remembering them is a hard task for some reason, like the only thing I can't remember PHP wise.

We should make a "cheat sheet"!

Make some notes keep them nearby when you're coding something.

Don't know if all, but almost all GD functions start with image :)
imagecolorallocate.. imageline.. etc
and the arguments are pretty much the same
image resource, x, y, w, h
or
image resource from_x, from_y, to_x, to_y...

Oh and bookmark: PHP: Image - Manual

What i do is think of an application that would need me to use alot of different GD functions and then just keep adding to it and sooner or later you kind of just remember them.

PHP Code:


			
<?php



/**
**  How to get an image from a resource
**/

# Set the header
header("Content-Type: image/png");
# if this is empty then it would return an error
$file = 'test.jpg';
# create it from $file
$im = imagecreatefromjpeg($file);

# Makes it easier for PNG files to have their colors correct!
imagesavealpha($im,true);

# generate it as a png file

imagepng($im);

/**End**/

/**
* Make your own IMages!~!!!!!! YAYYAYAY
**/# Set the header
header("Content-Type: image/jpeg");
$x = 200;
$y = 100;


$r = mt_rand(0,255);
$g = $r;
$b = $g;


 $im = imagecreatetruecolor($x,$y);
 $col = imagecolorallocate($im, $r,$g,$b);
 imagefilledrectangle($im,$x,$y,0,0,$col);


imagejpeg($im);

/**End**/
?>
