Can PHP 4 and 5 coexist on a single server?

[Justin L. Kennedy]

Our current webserver is a Linux Apache 2 engine running several websites
in separate virtual hosts. All of our websites were written for PHP 4,
and thus is the version of PHP running. But we are looking to host a copy
of MediaWiki which will start to require PHP 5 during the next major
release.

Since our existing sites are much to large to test and update to run under
PHP 5, I want to investigate whether we can install PHP 5 and configure
Apache to use PHP 4 for all the existings sites and use PHP 5 for the new
one.

Has anyone successfully done this, and how?

Sorry to intrude, Justin and all,

I am looking to do the same on an Windows XP machine.
I have PHP 4 and Apache 2.0.55 configured and running. Looking to
install PHP 5, and be able to switch b/w them, to test different code.

Sincerely,
Tariq

For development purpose, it's probably easiest to run multiple
instances of Apache 2.

First, open C:\WINDOWS\syst em32\drivers\et c and add a couple aliases to
the loopback address, like so:

127.0.0.4 php4
127.0.0.5 php5

Now, when you type in http://php5/ the browsers goes to one address and
when you type in http://php4/ it goes to another.

Second, create two copies of httpd.conf, name them httpd.php4.conf and
httpd.php5.conf (or whatever you feel like). In each, look for the
Listen directive and change it from 80 to 127.0.0.4:80 and
127.0.0.5:80. Put in the appropriate directives for loading the PHP
modules. You will likely want to use the PHPIniDir directive to set
the locations of php.ini.

Third, if Apache 2 is set up as a service already, remove it. Open a
command prompt window, cd to the Apache 2 bin folder, and enter "apache
-k uninstall." Then add two separate Apache services with the
following:

apache -k install -f conf/httpd.php4.conf -n "Apache 2 (PHP 4)"
apache -k install -f conf/httpd.php5.conf -n "Apache 2 (PHP 5)"

When you open up Services under Administrative tools, you'll see the
new services. Activate them. If the Apache monitor is running, restart
it. Then you'll see the two services there as well.

Finally, go to a phpinfo page at each location and verify the version
and php.ini path.


Happy coding!

This feature is present in WAMP serwer.

Yes, you can do that. You have to setup different application types in
the Apache conf, and then you can map the php suffix to any of them.
This can be done on a per-directory base using .htaccess (will be
propagated to all directories underneath as well).

HTH-!

When installing PHP 5, are there precautions to make sure it won't
overwrite files from PHP 4?
