The functions used are curl_init, curl_setopt, curl_exec, curl_close.

The default is GET method, you can choose whether to use Header:

curl_setopt($ch, CURLOPT_URL, "$url");
curl_setopt($ch, CURLOPT_TIMEOUT, 2);
curl_setopt($ch, CURLOPT_HEADER, 1); //如果设为0，则不使用header
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
$result = curl_exec($ch);

POST method:

$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,'＄url');
curl_setopt($ch,CURLOPT_POST,1);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,TRUE);
$vars =sprintf('from=%d&to=%d&subject=%s&body=%s',$from, $to, urlencode($subject), urlencode($body));
curl_setopt($ch,CURLOPT_POSTFIELDS,$vars);
$ret = curl_exec($ch);
curl_close($ch);

HTTP requests include POST and GET. When writing a form, you can specify the action as post or get. The array $_POST stores the variables passed by the POST method, and $_GET stores the variables passed by the GET method. $_REQUEST contains both.
For example

It depends on whether your submission method is GET or POST. Generally, form submission has a method specified, and $_GET is used to retrieve the information passed in the address bar, such as: www.tbsoo.com/cases.htm?s=&page=4 where the page is Use GET to get it. If your PAGE is submitted from the form, then use $_REQUEST, or write a judgment. If you cannot get it with GET, use POST, but it is most convenient to use REQUEST
