I often saw the php.ini memory_limit but I haven't found the answer to my question.
What EXACTLY is the memory_limit in php.ini?
Please post an detailed example.
Thanks :)
PHP’s memory_limit setting is not a storage space where multiple PHP scripts pool form or grow. The 'memory_limit' directive sets the maximum amount of memory that a PHP script can use. Note that this is dynamically allocated, and not reserved memory. If a script exceeds this value, PHP will report a fatal error.
Fatal error: Allowed memory size of x bytes exhausted (tried to allocate x bytes)
The error means that the allowed memory limit of x bytes configured on your server(memory_limit=xM) was reached while the PHP script tried to allocate y bytes.
It's the limit of the memory of the php script. It avoids than bad code fill the server memory, crashing it.

I am getting the following error on my Drupal site:
Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 205668 bytes).
To be sure, 268,435,456 + 205,668 = 268,641,124 bytes = 256.2 MB.
In my php.ini I have memory_limit = 2G. I have verified that I am editing the correct php.ini file. When I xdebug the site and enter ini_get('memory_limit'); into the console, I receive 2G for the output. So I know my file is being read correctly.
I've also checked my .htaccess file to verify that there are no other memory directives in there. There are not. Where is this limit coming from?
It turns out that this site has Drupal's path_memory module enabled, and the path I was trying to hit was configured to have a maximum of 256M available at admin/config/system/path-memory. Tricky.
1) You sir must have a ton of memory to apply 2 gigs for EACH HTTP/PHP process.
2) php memory_limit does not accept 'G' as a proper setting, make it 2048M instead
How to increase memory limit for PHP over 2GB?

I cant understand what this error mean? can u help me please?
This means that your PHP script has used up all of the memory that was allocated to it.
You should consider increasing the value of the memory_limit directive in your php.ini file.
Here is an extract from the documentation:
memory_limit
This sets the maximum amount of memory in bytes that a script is allowed to allocate. This helps prevent poorly written
scripts for eating up all available memory on a server. Note that to
have no memory limit, set this directive to -1.
Together with that, if your script is not supposed to use up so much memory you might have a bug in your logic that causes your script to run for too long or use up too much resources. Increasing the memory_limit will probably suppress that error you're getting, but it will not fix the reason you're seeing that error in the first place. Consider doing some code review on your script to find out why it's eating up resources.

Increase your memory limit in php.ini file
I'm getting this error:
Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 3456 bytes) in /home/gigiphot/public_html/Includes/thumbnail.inc.php on line 158
and this PHP memory limit is set to 64mb .. do I increase it? Not sure of next step...
You can set memory_limit in your php.ini file, see here: http://php.net/manual/en/ini.core.php
However, you may want to investigate if you really need such a heavy memory consumption... if this service will be used by multiple users concurrently, you may have problems... An unintended high memory consumption is often a symptom of something going wrong in your script.
Try adding ini_set('memory_limit', '128M'); to the top of the file.
You can set it to -1 to ignore the limit, but it's not generally recommended.
(This is a very frequent error, but couldn't find the meaning.)
Fatal error: Allowed memory size of x bytes exhausted (tried to allocate y bytes)
I have some questions:
This is obviously an out-of-memory error, but what does it means in Layman's terms?
Is it possible to know some information (like server's RAM) from x?
What about y? Sometimes it is a two-digits number.
Thanks.
It means that the memory used by the PHP script exceeded the value of the memory_limit configuration option. Note this may or may not agree with what the operating system thinks the memory usage of the script is at the time of the error.
x gives you the value of the memory_limit configuration option. You can also assume that the server has at least enough virtual memory to handle the limit, but that's about it.
No, y is just the size of the straw that finally broke the camel's back.
x = ini_get('memory_limit');
y = the php request that exceed that limit
The ram here isn't a problem, make a better php script or just rise memory_limit with ini_set
Anyway your question is a dup and a simple google search would solved it
This error is triggered because the PHP interpreter has a memory size limit for the scripts it runs. The "x" part is that limit, "y" is the allocation that caused the script to trigger the error. To override this, you can use either something like:
php_value memory_limit xxxM
in your server configuration or
memory_limit = xxxM
in the PHP configuration or
ini_set('memory_limit', 'xxxM');
in the script itself.

hi,
i m tring to run the program, but I keep getting this error;
Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 12 bytes)
plz, help me
Here is a simple tutorial here it will work.
This error message can spring up in a previously functional PHP script when the memory requirements exceed the default 8MB limit. Don’t fret, though, because this is an easy problem to overcome.
To change the memory limit for one specific script by including a line such as this at the top of the script:
ini_set("memory_limit","12M");
The 12M sets the limit to 12 megabytes (12582912 bytes). If this doesn’t work, keep increasing the memory limit until your script fits or your server squeals for mercy.
You can also make this change permanently for all PHP scripts running on the server by adding a line like this to the server’s php.ini file:
memory_limit = 12M
Keep in mind that a huge memory limit is a poor substitute for good coding. A poorly written script may inefficiently squander memory which can cause severe problems for frequently executed scripts. However, some applications are run infrequently and require lots of memory like importing and processing a big data file.

Locate your php.ini file and edit the memory_limit field
Increase max_memory in your php.ini file.
Either increase the memory limit defined in php.ini, or rewrite your code to use less memory (e.g. by freeing up resources or variables that won't be cleaned automatically by PHP's garbage collection), or give us more detail so that we can try to help. "trying to run the program" doesn't really tell us much, eg. what program?
Before you change the memory limit you should check if your code needs that much memory in the first place. It's a very unusual scenario for that to be the case - usually this is an indicator of:
1) incorrect config elsewhere, e.g. in webserver
2) inefficient management of resources in your code
3) unbounded loops/recursion
