Fatal error: Allowed memory size

[jasondavis]

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 12288 bytes) in /home/friend/public_html/config/image_function.inc.php on line 64

When I try to upload an image larger then like 1mb to my site I get this error, how can I avoid this?

33MB is much.
There maybe is some other thing in your script that 'eats memory'
as your file is like 1 MB.

A usual default was 8 MB 16 MB memory in PHP.
And this should be enough to most things.
Later version have by default 128MB, I think. ( my current memory_limit 128M )
If you get error while uploading files smaller than 8MB
I cant see why you should get such error.

is there a way to check my memory?

This is not necessarily true - the amount of memory an image takes is not based on the image's filesize.

When the GD library opens an image for processing, it opens it in its raw, uncompressed form. You didn't specify what time of image this is, but if you have a 1MB JPEG image file, it can easily exceed a maximum memory of 32MB, which your server is currently set at.

I don't remember the exact conversion, but it had something to do with multiplying the dimensions of the image, bits, etc. One function I've used in the past to allocate memory for an image before loading it into the GD library is this:

function setMemoryForImage( $filename ){
    $imageInfo = getimagesize($filename);
    $MB = 1048576;  // number of bytes in 1M
    $K64 = 65536;    // number of bytes in 64K
    $TWEAKFACTOR = 1.8;  // Or whatever works for you
    $memoryNeeded = round( ( $imageInfo[0] * $imageInfo[1]
                                           * $imageInfo['bits']
                                           * $imageInfo['channels'] / 8
                             + $K64
                           ) * $TWEAKFACTOR
                         );

$memoryLimitMB = ini_get('memory_limit');
$memoryLimit = $memoryLimitMB * $MB;
if (function_exists('memory_get_usage') && 
    memory_get_usage() + $memoryNeeded > $memoryLimit) 
{
    $newLimit = $memoryLimitMB + ceil( ( memory_get_usage()
                                        + $memoryNeeded
                                        - $memoryLimit
                                        ) / $MB
                                    );
    ini_set( 'memory_limit', $newLimit . 'M' );
    return true;
} else {
    return false;
}
}

I'm pretty sure I got that from a user-contributed note in the manual, just not sure which page.

Anyway, you'll definitely want to increase your maximum memory allowed - 32MB is rather tiny.

What do you mean "check" it? Check how much RAM your server has? How much a script is using at a certain point? ... ?

[jasondavis]

here is my upload code, can you show me how to add in the memory set function listed above?

<?PHP
if ($_POST['photosave'] != '') {
	list($height, $width) = getimagesize($HTTP_POST_FILES['picture1']['tmp_name']);
	if ($HTTP_POST_FILES['picture1']['name'] != '') {
		//get folder number to upload into for folder balance

		$filename = $HTTP_POST_FILES['picture1']['name'];
		$fil_ext1 = pathinfo($filename);

		$uniq = uniqid(rand());
		$filename = $uniq . $info['auto_id'] . '.' . $fil_ext;
		$type = $HTTP_POST_FILES['picture1']['type'];
		$PATH = "uploded_files/userphoto/" . $folder;
		make_dir($PATH); // iF directory does not exist - make it and chmod 0777
		$PATH = $PATH . "/";

	if (image_valid($type)) {
		$upload = uploadFile1($PATH, $filename, "picture1");
		$size = filesize($PATH . $filename);

			$h = 700;

			exit;
		} else {
			$sql = "INSERT INTO friend_user_photo (userid, photo_name, caption,defaultphoto, submitdate) VALUES('$info[auto_id]', '$folder/$filename',  '$caption','no', now())";
		}

		executequery($sql);

		$msg = "Your Photo Successfully Uploaded!.";
	} else {
		$msg = "Not a valid image only upload jpg ,gif or png!.";
	}

} else {
	$msg = "Your Photo Not Uploaded !.";

if ($info['newregister'] == "yes") {
	$msg .= " You can invite your friends";
	$_SESSION['sess_msg'] = $msg;

	exit;
}
}
?>

All you'd do is add the function to your script and call it inside the resizeImg() function before you load the image.
