sending sms online, polling the sms server

[phpmady]

Hi,



I am calling the sms service provider server with the following code


$url = $urlAccount_home."?username=".$userAccount."&password=".$passAccount."&number=".$number."&sender=".$userSenderSMS."&msg=".$msg;


             if (!($fp =fopen($url,"r")))
		echo "<br><center>خطا في الاتصال </center><br>";

		$result =fread($fp,10);
		fclose($fp);

 

 

 

When sending sms to 1 person no problem, but when sending sms to more than 1 person example for a group,

 

i will poll the serve in loop...

 

what am afraid is calling the server more than once continuously, wont affect the service?
