I have tried setting the limit in php.ini but I always get the same error:
Allowed memory size of 262144 bytes exhausted (tried to allocate 341351 bytes) in Unknown on line 0
I can work around this by calling php -d memory_limit=2048M script.php
But can't figure out what to do with composer.
As PHP-CLI has a different ini file, this often leads to misconfiguration.
What we can do, for a «unix shebang» PHP shell script, is to set ini keys on the fly directly on the shebang line, like so:
#!/usr/bin/php -d memory_limit=512M
<?php
phpinfo();
exit;
Then to see if php had understood, using phpinfo():
./myphpProg | grep memory
Correct shell output should contain:
memory_limit => 512M => 512M
man php
-d foo[=bar] Define INI entry foo with value bar
Without using the Unix shebang mechanism, we can similarly pass one (or many) -d arguments in the command line, or a dedicated start-up script:
php -d memory_limit=512M myphpProg
Add this at the very top your code of PHP
ini_set("memory_limit", "2048M"); in your PHP script. Make sure to increase memory_limit according to your need.
If you keep on getting this kind of error message of exhausted memory. you can use ini_set("memory_limit", "-1");. This will set your memory limit to no limit.
Note: This will set your memory limit to no limit. Memory limit is the thing which is dependent on your
OSandRAMnot onPHP.Note: Also please make sure if you are doing something on your production environment in your PHP script, whose job is to keep on adding data to there script, either in your static variables(Example:
gathering multiple CSV's data) or some arrays, then it can lead to either failure of that VM or PHP process in case of complete memory exhaust.
The default php.ini file for the CLI in xampp is located in %xamppRoot%\php\php.ini not under %xamppRoot%\apache\bin\php.ini
php -ito find out which php.ini file it is loading on the CLI and set yourmemory_limitthere. The ini in use should be near the beginning of the output.
