[Solved] Problem allocating memory

[prestacoco]

Hi,

At the prestashop root, I have a test.php script with this content

require('./config/config.inc.php');

error_reporting(E_ALL);
ini_set("memory_limit", '2048M');
ini_set('default_socket_timeout', -1);
set_time_limit(0);
ini_set('display_errors', 'on');

$size = pow(2, 18); //2^18 = 262144, 2^17 = 131072

$startTime = microtime(true);

$array = array();
for ($key = 0, $maxKey = $size - 1; $key <= $maxKey; ++$key) {
	$line = ['id' => 55, 'ref_1' => "JKJKJ798798", 'ref_2' => "AKUYT798798", 'id_test' => "TEST798798", 'id_category' => 18, 'desc_long' => "L'investissement immobilier s'avère être une valeur sûre pour de nombreux investisseurs.

    $array[$key] = $line;
}

$endTime = microtime(true);

echo 'Inserting ', $size, ' good elements took ', $endTime - $startTime, ' seconds', "\n";

I run it in command line "php test.php" and I have this error

mmap() failed: [12] Cannot allocate memory

mmap() failed: [12] Cannot allocate memory

Fatal error: Out of memory (allocated 195039232) (tried to allocate 20480 bytes) in /home2/stocketik/public_html/test.php on line 16

No matter if I increase memory_limit, I always get the error.
If I set memory_limit to 128M I have the following error "Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 20480 bytes)" which makes sense.

The strange thing is that if I remove the require line the script runs successfully.

Has anyone ever encountered this problem? How can I solve it ?

Removing the require line is not the solution. I just made this script as a POC and to simplify my problem. In my real scenario I have a script which makes a database request (a select using Db::getInstance()->executeS($sql_select)) and it crashs.

 For further information, I'm using PS 1.7 and PHP 7.0. I also tried with PHP 8 and same problem.

Hi.

2048M = 2G

ini_set('memory_limit', '2G');

or

ini_set('memory_limit', '2147483648');

You need to find out if your value is out of range. ini_get('memory_limit);

I did ini_set("memory_limit", '2048M'); which is present in my script. ini_set("memory_limit", '2G'); Or ini_set("memory_limit", '2147483648'); are exactly the same.

I have completed the answer. See if it's out of range.

@prestacoco Can you send a phpinfo screenshot?

Before the require, memory_limit is 4096M (I think my hosting provider increased the value) and after the require I echo the ini_get('memory_limit') and it continues to be 4096M.

Look in the php info, there will definitely be two different values for memory_limit

https://www.php.net/manual/en/function.phpinfo.php

or Admin shop (left menu) => Advanced Parameters => Information.

Thanks for your help. I was contacted by my hosting provider and he explained me that there was a shell restriction and he removed this restriction.
It was not related to memory_limit.

I think this page https://support.cpanel.net/hc/en-us/community/posts/19163447287703-Max-Memory-for-a-User can give more information about the problem I encountered. As a shell user, I was limited to 200M of RAM for a process so even if I was increasing memory_limit it did not solve my problem.

Hope this can help other users encountering the same problem.
