If you are having composer memory limit issues
COMPOSER_MEMORY_LIMIT=-1 composer install
This will temporary remove the php memory limit. -1 (infinite memory usage) is not recommended if the server is running a site/sites that is/are live as it could overload the server. In this scenario use a different memory size e.g.COMPOSER_MEMORY_LIMIT=512M
. If the server is in maintenance mode then -1 should be fine to use, just be cautious. To find your current memory limit setting run: php -i | grep "memory_limit"
Memory limit issues in scripts
Put the following
ini_set('memory_limit', '64M');
Useful commands on Mac
To find your php.ini file run:
php -i | grep "Loaded Configuration File"
or:
To find all php.ini files on your machine:
sudo find / -name php.ini
kill the process after the main process has finished using Ctrl + C.
To get the memory limit:
php -i | grep "memory_limit"
Useful commands on Linux
To view locations of all of your php ini files (on linux only - To install do: sudo apt install mlocate
):
locate php.ini
php -i
gives a print out of the ini php which your php is using.
To find he location of this ini file run:
php -i | grep "Loaded Configuration File"
Sometimes a there are two php.ini files -> like in Laravel Forge where there is one for the CLI and one for the FPM.
To view how much space is allocated in your CLI php ini file:
php -i | grep "memory_limit"
To view how much space is used in your FPM ini file (change to php version):
grep "memory_limit" /etc/php/7.3/fpm/php.ini
to view peak usage in a script:
var_dump(memory_get_peak_usage()/1024);
Normal directory:
cd /etc/php/7.4
