I am trying to clear the cache of my web app, on Putty:
php app/console cache:clear --env=prod
However I get a Fatal error: Allowed memory size of 67108864 bytes exhausted...
I changed my .user.ini to 128M and the info.php displays the proper value of 128M. However when I run the command in putty, I still get a message
Fatal error: Allowed memory size of 67108864 bytes exhausted...
Why is the display correct on info.php and incorrect in the error message?
It is possible that the PHP that runs via the web and the PHP that runs from the command line use different ini files. Try php -i from the command line and see which ini file it uses. Alternatively try the php -c your.ini.file to specify an alternate ini file.
See the full list of options here: http://php.net/manual/en/features.commandline.options.php
Edit: As requested, the specific command line to use:
php -c /some/dir/your.php.ini app/console cache:clear --env=prod
