How to install and configure php in openwrt

Question

I have developed some pages in PHP and HTML. But the PHP pages were not working when I put these pages in OpenWrt www folder. I have installed php5 in OpenWrt. These pages were working fine with apache localhost in ubuntu. In OpenWrt, It has uHTTPd. Do I need to install anything other than just php5 (other modules) or Do I need to configure something?

Answer 1

For PHP5 configuration on OpenWRT see: http://wiki.openwrt.org/doc/uci/uhttpd

First, install PHP

opkg update
opkg install php5
opkg install php5-cgi

Install any other additional php5 extensions you may use. To see available packages:

opkg list php5*

Example:

opkg install php5-mod-sockets

Open your /etc/php.ini and uncomment any of the extensions you just installed. Continuing with the sockets example above the following:

;extension=sockets.so

becomes

extension=sockets.so

Now open /etc/config/uhttpd and add the following line:

list interpreter ".php=/usr/bin/php-cgi"

Don't forget to restart uhttpd:

/etc/init.d/uhttpd restart

One option in regards to your space (flash) limitations of installing PHP on your embedded device: if you have access to a USB port on your embedded device (like many do) you can set up your base openWRT configuration with extroot. Essentially you will boot to a USB drive thereby enabling all of the space of the USB drive to install packages and add files. See: http://wiki.openwrt.org/doc/howto/extroot

Answer 2

Actually you do need to install a server (such as Apache), and if you want data persistence, a database (such as MySQL)
