how do I check against the PHP version?

[lawrence]

I'm writing an installation script for my PHP content management
system. I've written the code to be compatible with PHP 4.06 or later.
I need to get the PHP version and throw an error message if the
version is less than 4.0.6. I realize that phpinfo outputs the info,
but what function would get me the version string?

There's a function called phpversion() and a constant called PHP_VERSION

Refer to http://www.php.net/php_version for more information

Also see "version_compar e" which lets you test if a version is equal to or
greater.

Of course, that's only good if the installation is 4.1.0 or greater :)
There is a version check function in HoloLib:
