PHP and PW minimal requirements

[Nico Knoll]

Hey,

it would be nice if you could add something like 'php_version_required' => '5.3' to the modules config and the module managment section of PW would show something like "You have to update to PHP 5.3 to use this module" or so. That would prevent that modules which need a newer version of PHP or PW would disturb the running system.

Do any modules need a newer version of PHP than ProcessWire itself? Guess it's never come up before, but I suppose it could. PHP actually has a very handy function that you can use from your modules to compare against the PHP version or ProcessWire version:

if(version_compare(PHP_VERSION, '5.3.0', '<')) {
 throw new WireException("You must have PHP 5.3 or newer to install this module"); 
}

if(version_compare(wire('config')->version, '2.2.7', '<')) {
 throw new WireException("You must have ProcessWire 2.2.7 or newer to install this module"); 
}

I was thinking about making the PW version designation part of the getModuleInfo array so that PW would enforce it internally.

getModuleInfo - that's what i meant with "modules config". I guess it's much handier than include the code you posted
