Multi-PHP

Run multiple versions of PHP on one Apache instance on Slackware.

A couple of SlackBuild scripts to run multiple versions of PHP on the same Apache instance on Slackware. Currently only PHP 5.3 is supported but more versions will be added in time.

Build and install

Same procedure as using a regular SlackBuild, except for the following:

• It needs a full copy of the alpine source-dir from Slackware 13.37 (!!) to exist in the parent dir from where you're building (i.e. ../), just like when building regular PHP from Slackware. This is required for the IMAP support and the build will fail without it.
• The appropriate PHP source needs to be downloaded separately into the directory containing the SlackBuild, a fetch-php.sh script is supplied for your convenience.

Usage

• Build and install the php53 package

• Enable support for PHP 5.3 on your Apache server by including the /etc/httpd/extra/cgi-php53.conf file from your httpd.conf like so:

  # Uncomment the following line to enable PHP 5.3 CGI:
  #
  Include /etc/httpd/extra/cgi-php53.conf

  Note that this will only provide the 'php53-script' handler itself, to be used wherever needed. Any PHP file on your server will still be served as before, PHP 5.3 is only used if explicitly enabled. See the cgi-php53.conf file for more information.

• Use PHP 5.3 for each file or directory where it's wanted. To use PHP 5.3 for all files ending with '.php' in a given dir (and all its subdirs), add the following (either to the dir's .htaccess file or the appropriate section in httpd.conf itself):

  # Serve '*.php' files with PHP 5.3 in here
  <FilesMatch \.php$>
      SetHandler php53-script
  </FilesMatch>

  Additionally, to revert that behavior on some specific files inside that dir to Apache's default PHP handler (i.e. ignore the above for the given file(s)), use something like:

  # Specifically exempt filename.php, use regular mod_php for it
  <Files "filename.php">
      # NOTE: either 'application/x-httpd-php' (used in Slackware's
      #       mod_php.conf) or 'php5-script' works here, both are provided by
      #       mod_php.  Using 'php5-script' due to the similar naming-style.
      #       Named both in this comment as easy grep targets.
      SetHandler php5-script
  </Files>

  There are some other methods for using the php53-script handler, see the Apache documentation on handlers for more information on that. It should work wherever a handler can be used, if not, please report.
