Download and install PHP in Linux
From AlfrescoWiki
PHP is designed to run either from the command line by executing the php command, or through a web server (e.g. Apache). A guide to installing PHP on Unix (incl. linux) based systems can be found on the PHP documentation page. The summary below is a short summary of these instructions for Apache 1.x and 2.x.
[edit] Apache 1.x
The general summary for install with Apache 1.x:
Download the current PHP source from http://www.php.net/
./configure --with-apxs --with-mysql make make install cp php.ini-dist /usr/local/lib/php.ini
Now edit your Apache config file and add:
For PHP 4: LoadModule php4_module libexec/libphp4.so AddModule mod_php4.c For PHP 5: LoadModule php5_module libexec/libphp5.so AddModule mod_php5.c For both: AddType application/x-httpd-php .php .phtml
Now restart Apache:
apachectl graceful
[edit] Apache 2.x
./configure --with-apxs2 --with-mysql make make install cp php.ini-dist /usr/local/lib/php.ini
Now edit your Apache config file and add:
For PHP 4: LoadModule php4_module libexec/libphp4.so For PHP 5: LoadModule php5_module libexec/libphp5.so For both: AddType application/x-httpd-php .php .phtml
Now restart Apache:
apachectl graceful
[edit] Distribution specific installs
Your distribution may also contain a native version of PHP that you can install with utilities such as yum, up2date, apt-get or emerge (depending on your distribution). There will usually also be packages to install extensions (e.g. MySQL integration) that you may also need.
