title: how to call a URL in background using PHP
body: <p></p>I want to call a 3rd party URL, this URL is given to me by my SMS portal which is used to send SMS to end users.<br/>
  Now the problem is that when I call this URL through PHP the state changes and I'm redirected to that page, is there any method by which we can call this URL again and again, the reason I want to call the URL so many times is because there can be 1000 users so in the URL I have to mention the name of the user and there phone number.<br/>
  This process should be asynchronous.</p></p>
