Simple GET request with PHP cURL to send SMS text message
I'm creating quick web app that needs to send a php-created message from within php code. cURL is apparently the tool for the job, but I'm having difficulty understanding it enough to get it working.
The documentation for the API I'm dealing with is here. In particular I want to use the simple GET-based sms notification documented here. The latter resource states that the GET API is simply:
http://sms2.cdyne.com/sms.svc/SimpleSMSsend?PhoneNumber={PHONENUMBER}&Message={MESSAGE}&LicenseKey={LICENSEKEY}
And indeed, if I type the following URL into a browser, I get the expected results:
http://sms2.cdyne.com/sms.svc/SimpleSMSsend?PhoneNumber=15362364325&Message=mymessage&LicenseKey=2134234882347139482314987123487
I am now trying to create the same affect within php. Here is my attempt:
<html>
<body>
<?php
$num = '13634859126';
$message = 'some swanky test message';
$ch=curl_init();
curl_setopt($ch, CURLOPT_URL, "http://sms2.cdyne.com/sms.svc/SimpleSMSsend?PhoneNumber=".urlencode($num)."&Message=".urlencode($message)."&LicenseKey=2345987342583745349872");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
?>
</开发者_开发百科body>
</html>
My other PHP webpages work fine, so I know php and apache are all set up correctly. But When I point my browser at the above page, I get no message on my phone. Can anybody show me what I'm doing wrong?
Note: all numbers are faked... as you might have suspected.
Do you really need CURL? You simply use PHP's file_get_contents($url), which will do a GET request and will return response value.
If there's no return output, probably the cURL fails. Check the error code of the returned resource to determine the cause of the error.
$result=curl_exec($ch);
$curlerrno = curl_errno($ch);
curl_close($ch);
print $curlerrno;
The error code list: libcurl-errors
I advise to use cURL timeout settings too:
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,5);
curl_setopt($ch,CURLOPT_TIMEOUT,5);
Assuming you are forming the URL correctly and as one comment says check it manually in a browser I am not sure where your data is going when it comes back so try
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // tell the return not to go to the browser
$output = curl_exec($ch); // point the data to a variable
print "<br />"; // output the variable
print $output;
print "<br />";
Other things to try are
curl_setopt($ch, CURLOPT_INTERFACE, "93.221.161.69"); // telling the remote system where to send the data back
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)"); // pretend you are IE/Mozilla in case the remote server expects it
curl_setopt($ch, CURLOPT_POST, 1); // setting as a post
Just replace it
PhoneNumber=$num
curl_setopt($ch, CURLOPT_URL, "http://sms2.cdyne.com/sms.svc/SimpleSMSsend?PhoneNumber=".urlencode($num)."&Message=".urlencode($message)."&LicenseKey=2345987342583745349872");
