Integrate an API on a web registration form
<p>I have a website where users can register using their mobile number and the registered user get a text message confirming the registration. The page uses php. The mobile number gets stored as a variable $mobile.</p>

<p>The API for sending sms to the registered user is <code>http://someurl/&amp;message=[xxxx]&amp;numbers=[xxxxx]</code></p>

<p>I want to execute the API in the background. I need to know a way to pass the number stored in $mobile variable to the API's url?</p>
