cURL help

[c_pattle]

I have just installed cURL and am learn to use it but I'm not sure exactly what I am doing.  For example I have a page with this code on it. 

 

if($_GET['number'] == "6") {
    echo("<p>the number is six</p>");
}

 

Then I am trying to use cURL to send the number 6 to this page so that it returns "the number is 6".  However I am just getting an output of "1".  Below is the code I am using to try to get the output of "the number is 6". 

 

$ch2 = curl_init();

curl_setopt($ch2,CURLOPT_URL,'http://localhost/crawler/crawlertest.php');
curl_setopt($ch2, CURLOPT_POST, 1);
curl_setopt($ch2,CURLOPT_POSTFIELDS,'number=6');
$return = curl_exec($ch2); 

echo ($return);

curl_close($ch2);

 

Thanks for any help

$return is the return value of the operation, not the returned content if any.

 

curl_exec: Returns TRUE on success or FALSE on failure. However, if the CURLOPT_RETURNTRANSFER option is set, it will return the result on success, FALSE on failure.

 

You might only need to add this line before using curl_exec:

 

curl_setopt($ch2, CURLOPT_RETURNTRANSFER, true);

this looks like a good example of back-and-forth communication with curl:
