Multiple php Versions on the same Server


Some web server are pre-configured to run e.g. php4 and php5 at the same time, to ensure compatibility with older scripts and CMS systems.
If you web server is configured for multiple php versions, select the php version by using e.g.

somescript.php4  // for php4 (old) scripts
somescript.php5 // for php5 scripts
somescript.php // for the default php version

The default php version depends either on your php configuration or on your hosting package.
