Set php.ini Values Using .htaccess

Written by David Walsh on Tuesday, November 4, 2008

Did you know that you can set php.ini values right inside the .htaccess file? It’s actually very easy.

The .htaccess Code

#format
php_value setting_name setting_value

#example
php_value  upload_max_filesize  10M

Of course you could simply place these in the .htaccess file, but .htaccess is a viable alternative if your host doesn’t allow you to touch the php.ini file.

Another option is setting it in PHP – using the ini_set() function.

huh @guard?

So this could work for httpd.conf’s values too? Or this one cannot be overridden?

I actually used this just the other day. I was trying to use the “Import” feature of WordPress to import a bunch of posts and crap from an “Export” of another WordPress blog (XML File). WordPress was telling me there was a piddly 2MB limit. But apparently, this isn’t a limitation of WordPress but rather set by PHP running on the server. I upped it, but apparently it maxed at 8MB on my server, which was 2MB too small for my 10MB file. Booooo.

I’ll remember that one, thanks !

.htaccess has a lot of capabilities, do you know if there’s a reference for it, or a listing of the possibilities somewhere ?

@Ahmed: php_flag and _php_value can be written in httpd.conf in FastCGI, but not in .htaccess file. if PHP is running as module, you can do anything with .htaccess

@Chris Coyier: The upload limit is the one I change the most.

@Antoine Leclair: I haven’t found one great one — Google usually yields the best results.

Another way to do it is to use PHP’s native ini_set() function

Readers may be interested by reading this page on the PHP documentation : How to change configuration settings. That is said you can also use the ini_set php function, which is an alternative to the .htaccess method.

@Antoine Leclair: There is always the official documentation. You can find it for the last version of Apache, and you have a .htaccess tutorial.

Consider reading the following, to get better understading of .htaccess and how it works. It really depends on your httpd.conf what you can do with the .htaccess file.

Wow that’s exactly what I needed to simplify my life. Thank you!

Of course you could simply place
these in the .htaccess file, but
.htaccess is a viable alternative if
your host doesn’t allow you to touch
the .htaccess file.

Maybe you meant httpd.conf? Or php.ini?

I am not an experienced coder. I have access to the .htaccess file. What exactly do I need to put in the file to increase my Upload file size limit? I’d greatly appreciate any help. Thank you all!
