imagedestroy()

[iLL]

okey, I'm not really a PHP programmer, but I'm making an image viewer for my web page. I have a function that makes thumbnails for me

function addThumb($file)
{
	global $dirPath;
	global $thumbPath;

	$size		= getimagesize($dirPath.$file);		//Image size
	$thumbWidth	= 200;					//New width.
	$thumbHeight	= ($thumbWidth/$size[0]) * $size[1];	//New height

	$thumb		= imagecreatetruecolor($thumbWidth, $thumbHeight);	//New Image
	$source		= imagecreatefromjpeg($dirPath.$file);			//Open Image

	imagecopyresized($thumb, $source, 0, 0, 0, 0, $thumbWidth, $thumbHeight, $size[0], $size[1]);	//resize $source and save it in $thumb
	imagejpeg($thumb,$thumbPath.$file);	//save $thumb
}

So... do I need imagedestroy()?

I don't really know how PHP allocates or deallocates memory, but I'm thinking that the used memory is deallocated when the function ends. Am I wrong?

imagedestroy() will free the memory once you say so. Otherwise, the memory will be freed after all of the PHP on that particular page has finished.
