Re: [Phpwiki-talk] Assertion failed errors on flatfile phpwiki

[Joby W. <joby@u.washington.edu>]

php.ini is a server-wide config file that affects how php behaves for every php 
program.  It's location is highly dependant on what platform/distribution you 
are running (on Gentoo it is under /etc/php/).  If this is your box, to find it 
you could run:

find / | grep php.ini

If you do not have access to the php.ini file you can override most options with 
the ini_set() function (though I am not sure if all three can be overridden):

http://us2.php.net/manual/en/function.ini-set.php

I have:

max_execution_time = 300
max_input_time = 60
memory_limit = 16M

The 300s max_execution_time is a bit high, but I have some other administrative 
webapplications that take a long time.
