Running PHP 3 and PHP 4 concurrently

Recent operating systems provide the ability to perform versioning and scoping. This features make it possible to let PHP 3 and PHP 4 run as concurrent modules in one Apache server.

This feature is known to work on the following platforms:

  • Linux with recent binutils (binutils 2.9.1.0.25 tested)
  • Solaris 2.5 or better
  • FreeBSD (3.2, 4.0 tested)

To enable it, configure PHP 3 and PHP 4 to use APXS (--with-apxs) and the necessary link extensions (--enable-versioning). Otherwise, all standard installations instructions apply. For example:

copy to clipboard
$ ./configure \
 --with-apxs=/apache/bin/apxs \
 --enable-versioning \
 --with-mysql \
 --enable-track-vars
