SMS using PHP and WSDL

SalientAnimal · January 25, 2013

Hi All,

I'm not 100% sure if this is the place to be posting for help with this. I have managed to get some source code for a SMS PHP page. However I am having some problems getting it to work, mainly because I'm not 1005 sure how to configure it, and if I need to make any toher changes to the code in order to incorporate my SMS gateway.

The error message I am getting is: "SMS Sending Failed Message:Network error unable to send the message", this mesage is however coded into the code.

Below is the code of the 4 different pages:

HTML Page where message is created
