Setup a simple cURL connection to POST data using PHP

Error message

Deprecated function: Methods with the same name as their class will not be constructors in a future version of PHP; GeSHi has a deprecated constructor in require_once() (line 915 of /home/digipiph/public_html/sites/all/modules/libraries/libraries.module).

cURL is used to send "POST" data from one web page to another behind the scenes.

If cURL is enabled on your server, it is fairly easy to setup. I had trouble finding a page that broke setting up a cURL connection down to its most simplest form by showing a cURL example, so I decided to post a page for it.

Example: cURL setup with PHP

//set up a connection variable for the page you will post data to
$curl_connection = curl_init('');
//curl basic setup
curl_setopt($curl_connection, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($curl_connection, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)");
curl_setopt($curl_connection, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl_connection, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl_connection, CURLOPT_FOLLOWLOCATION, 1);
//$_POST variables to pass
$post_items[] = 'firstname='.strip_tags($_POST['firstname']);
$post_items[] = 'lastname='.strip_tags($_POST['lastname']);
$post_items[] = 'item='.strip_tags($_POST['item_id']);
//format the $post_items into a string
$post_string = implode ('&', $post_items);
//send the $_POST data to the new page
curl_setopt($curl_connection, CURLOPT_POSTFIELDS, $post_string);
$result = curl_exec($curl_connection);
