Increasing PHP environment memory and file upload limits on Pair Networks virtual hosting


Increasing the PHP environment memory and file upload limits on virtual hosting account is a common question. This is especially true when your working on a WordPress site and the file upload limit is restricted at 4MB.

This limit can be changed. There are several methods such using .htaccess, using a WordPress plugin etc. What works will depend on how your hosting environment is setup. This information applies to new Pair Networks hosting accounts but will also work with other hosting providers that allow personal php.ini settings.

On Pair Networks, if you have a fcgi-bin folder on your hosting account, then the following will work.

Create a file call “php.ini“.

It should look like this:

memory_limit = 64M
post_max_size = 32M
upload_max_filesize = 32M

Upload “php.ini” into the fcgi-bin folder.

Wait for about 10 minutes to an hour. As soon as all PHP sessions close, the hosting account will naturally re-start PHP.

If you absolutely must have the setting changes urgently, do this:

Connect to your account using SSH and kill the PHP process to force your changes to become effective.

kill -9 `ps auxww | grep php5.cgi | awk ‘{print $2}’`

You may get an error “No such process”. Ignore it.
