Detailed explanation of CURL
curl_close — Close a curl session
curl_copy_handle — Copy all contents and parameters of a curl connection resource
curl_errno — Return a numeric number containing the error information of the current session
curl_error — Return a string containing the error information of the current session
curl_exec — Execute a curl session
curl_getinfo — Get information about a curl connection resource handle
curl_init — Initialize a curl session

curl_multi_add_handle — Add a separate curl handle resource to a curl batch session
curl_multi_close — Close a batch handle resource
curl_multi_exec — Parse a curl batch handle
curl_multi_getcontent — Return a text stream of the fetched output
curl_multi_info_read — Get the currently parsed Curl related transmission information
curl_multi_init — Initialize a curl batch handle resource
curl_multi_remove_handle — Remove a handle resource in the curl batch handle resource
curl_multi_select — Get all the sockets associated with the cURL extension, which can then be "selected "
curl_setopt_array — Set session parameters for a curl in the form of an array
curl_setopt — Set session parameters for a curl
curl_version — Get curl-related version information
The role of the curl_init() function is to initialize a curl session. The curl_init() function is unique One parameter is optional and represents a url address.
The curl_exec() function is used to execute a curl session. The only parameter is the handle returned by the curl_init() function.
The curl_close() function is used to close a curl session. The only parameter is the handle returned by the curl_init() function.

  $url = 'http://www.@@@@@@.com/';
 //Initialize curl
 $curl = curl_init($url);
 //curl Timeout 30s
 curl_setopt($curl, CURLOPT_TIMEOUT, '30');
 //user-agent header
 curl_setopt($curl, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:14.0) Gecko/20120722 Firefox/14.0.1");
 //Return to file stream
 curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
 //Open header file data stream output
 curl_setopt($curl, CURLOPT_HEADER, 1);
 $string = curl_exec ($curl);
 var_dump($string);
 preg_match_all('/Set-Cookie:stest=(.*)/i', $string, $results);
