Running PHP4 and PHP5 concurrently.

Running PHP4 and PHP5

There are many times when we need PHP4 and PHP5 to run concurrently on the server.In such cases we can Install one as apache module and other as CGI

Install PHP4 or PHP5 as apache module. Lets install PHP5 as apache module

Download PHP5 untar it and move to its directory.

1.  ./configure --with-apxs=/usr/local/apache/bin/apxs

2.  make

3.  make install

If file /usr/local/apache/modules/libphp5.so does not exist or is an older version, type this from PHP source code directory.

 4 cp -p .libs/libphp5.so /usr/local/apache/modules

5 copy php.ini-recommended from PHP source code directory to installation directory.

6 Add following to http.conf

LoadModule php5_module        modules/libphp5.so

AddHandler php5-script php

DirectoryIndex index.html index.php

AddType text/html       php

Now install PHP4 as CGI

Download PHP4 untar it and move to its directory.

1 ./configure --prefix=/home/somedir/php4 --enable-force-cgi-redirect --program-suffix=4

–enable-force-cgi-redirect- Enable the security check for internal server redirects. Not enabling option disables the check and enables bypassing httpd security and authentication settings.

–program-suffix -adds the given suffix.

2 make

3 make install

4 Add following to http.conf

Action application/x-httpd-php5 "/cgi-sys/php-cgi5"

AddHandler application/x-httpd-php5 .php5
