As far as I know (two years have passed since I used PHP), it's all the same.
If the client application will be built using the built-in SoapClient class from PHP, you should offer an endpoint that uses basicHttpBinding, since it conforms to the WS-I 1.1 base profile and PHP does not offer additional support for any other standards.
I wrote a post about using WCF services with PHP 5 a while ago:
http://cgeers.com/2009/08/20/using-wcf-services-with-php-5/
It explains how to configure the WCF service and how to use it using PHP 5.
