With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution

code working via apache, not on command line; how to fix

Asked by DoppyNL in PHP Scripting Language

Tags: zend, php, 5, command line, memory jpg jpeg image

Hi,

I've got some code that is to process images in the background. I'm making a cron-job for this wich I will be running from the command line.
The code works just fine when I request the script via de web (via Apache), but it crashes when I run it from the command line.

The crash happens on this line:
$this->original_handle = imagecreatefromjpeg($this->original);
Where I believe that the function imagecreatefromjpeg is the problem.

I think the problem is caused by lack of memory, when requested from the web I use the attached function to increase the memory in PHP to be able to process the image.
I don't use this function on the command line, because when I do it crashes on the line I marked.

How can I adjust my code so it also works on the command line?
Why doesn't it work on the command line?

The last is also interesting for me, as I got a similar problem for another cronjob that fails to send out emails from the command line.

             <?php
	static private function increase_memory($image_info)
	{
			$MB = 1048576;
			$K64 = 65536;
			$tweakfactor = 1.7;
			$memory_needed = round(	(	$image_info[0] * $image_info[1]
												* $image_info['bits']
												* $image_info['channels'] / 8
												+ $K64
											)
											* $tweakfactor);
			$memory_limit = ini_get('memory_limit');
			$memory_limit_new = $memory_limit + ceil((memory_get_usage() + $memory_needed - $memory_limit) / $MB); // <- Command line crashes here
			ini_set('memory_limit', $memory_limit_new . 'M');
	}
