[RESOLVED] Fatal error & Getimagesize

lajkonik86

Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 11519354 bytes) in

list($game['flashw'][$key],$game['flashh'][$key]) = getimagesize(INT_GAMES . "$value/" . $newname);

How do i get around this?
Suppose the flash file is quite big about 6 megs

You could try adding this to the start of the script:

ini_set('memory_limit', '20M');

im on a shared server, will my host shoot me for this?

lajkonik86

I just need the width and the height of the flash file.
Why does the memory usage go so all over the top?

NogDog

I'm assuming (perhaps incorrectly) that the function is loading the image file into memory before it does whatever it does to get the size info.

lajkonik86

that could very well be. Dont know how php handles that.

In that situation I would still need only the memory for one file.

Is there anyway i could clear the memory the function used after getting the width and the hight? It's in a foreach loop.

Could i use unset() to do this? Dont think so cause the memory being used is actually not a variable

Im lost on how and what php stores in its memory🙂

NogDog

Can you show us your code?

Also, for some debugging you might want to throw in some calls to memory_get_usage() to find out how much memory is reserved for the script at different points (to help narrow down where the memory gets used up).

This would be a lot of work, but depending on your personality it could be very fun work. getimagesize() is a function that does many things, so it probably does load the entire file into memory. You could, instead, open a file handle to the file, and read the width and height out of the headers. I had to do this with gif files because the gd library has very limited support for gifs, so I can see if I can modify the code to grab the header of a swf file. Here is a page I found on google that shows the structure of a swf file:

and here's a class in Java that does the same thing:

wow thanks for the good posts.

I dont recieve the error if i leave out that single line. So that definitly has to count for quite some usage. Thanks for the function to quantify those beliefs🙂

Is there any way i could remove that memory usage after getting the width and height of a single flash file, before moving on to the other?

NogDog

One would hope that the function automatically releases the memory once it's done returning the data array.

Here is the usage in the foreach loop with the getimagesize commented

echo '<br>before' . memory_get_usage();
//list($game['flashw'][$key],$game['flashh'][$key]) = getimagesize(INT_GAMES . "$value/" . $newname);
echo '<br>after' . memory_get_usage();

Gives:
before104104
after104152
before107088
after107088

Now with list statement
before105456
after106192
before108848
Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 11519354 bytes) in /home/descon/public_html/flashgames/upload3.php on line 55

However the flash file its reading from is only 5.6 megs:S

well it appears that setting the ini file is the only way to fix this problem.
Tried it and memorry usage drops nicely back after the operation.
