2 MB is extremely low. You're going to want to increase your memory limit. — Mike, Aug 04 '18 at 03:19

You probably have either:

An entity related to thousands of other entities, and by the time you get to a very high amount of records being serialized, memory maxs out, or...
A circular reference in one of your entities

Increasing the memory limit may fix it if is not a circular reference, but that's not a proper fix. You have to be efficient. Control your hydration and references. Also, IMO, JMS Srializer is not the best tool for a presentation layer. Try league/fractal.

use this command to increase memory allocated: php -d memory_limit=-1 bin/console server:run

or increase this option in php.ini in your php folder.

Setting `memory_limit` to `-1` is considered to be a bad practice though. – Pavel Vasiluk Aug 04 '18 at 11:04
the problem is that i can't touch the php.ini in the server, and that doesn't work on .htaccess – Skander Ben Khelil Aug 04 '18 at 11:13
-1 can be changed with any value followed by a measure unit: 128M or 1G... if you cant touch php.ini and you have access to the server panel there will be a php configuration page to adjust the memory if not you should call the server administrator to make the appropriate changes – Abdelhafid El Kadiri Aug 04 '18 at 11:19
is this in your computer: C:\Users\Messkan\Desktop\businessplace – Abdelhafid El Kadiri Aug 04 '18 at 11:28
if so, you can run a php local server instead of symfony server:run using "php -S localhost:8888" then access your app with "localhost:8888/web/app_dev.php/" – Abdelhafid El Kadiri Aug 04 '18 at 11:32

You need to increase memory_limit value in php.ini file for the php version you are using (e.g. php7.0).

So navigate to your php.ini file there, find memory_limit line in this file & try to set value to 1G or 2G (depending on the app size, - how much you really need). Save changes & restart your server (apache/nginx), and try once again.

Try adding new line `php_value memory_limit 1G` to your `.htaccess` file – Pavel Vasiluk Aug 04 '18 at 11:23
