Construct a POST request using CURL in php

: This article mainly introduces the use of CURL in php to construct POST requests. For more information about PHP tutorials, see.

Hey, I started my first blog post below. the idea of writing a blog has been around since I started my work, but I have been writing it for a long time, probably because I am lazy.

In recent projects, we need to construct POST requests to transmit data from the backend, so I learned a little bit and want to put this po on the blog. it's better to remember it than to write it down.

Functiontest () {$ url = '/Common/adduser'; // the url you want to request $ data = array ('username' => 'commandid dand ', 'password' => '000000', 'tel' => '000000'); // the data you need to transmit $ ch = curl_init (); // open a handle // set various values curl_setopt ($ ch, CURLOPT_URL, $ url); // Set the URL curl_setopt ($ ch, CURLOPT_POST, 1) to be crawled ); curl_setopt ($ ch, CURLOPT_HEADER, 0); // header information, which is generally false curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ ch, CURLOPT_POSTFIELDS, $ data); $ result = curl_exec ($ ch); // Obtain the returned value curl_close ($ ch); // Close the handle return $ result ;}

The above code can basically construct POST requests in the background...

Below are some functions in CURL
Curl_close-close a curl session
Curl_copy_handle-copy all content and parameters of a curl connection resource
Curl_errno-a number containing the current session error message is returned.
Curl_error-returns a string containing the current session error message.
Curl_exec-execute a curl session
Curl_getinfo-obtains the information of a curl connection resource handle.
Curl_init-initialize a curl session
Curl_multi_add_handle-add a separate curl handle resource to the curl batch processing session
Curl_multi_close-close a batch processing handle resource
Curl_multi_exec-parse a curl batch handle
Curl_multi_getcontent-return the obtained output text stream
Curl_multi_info_read-obtains the transmission information of the currently resolved curl.
Curl_multi_init-initialize a curl batch processing handle resource
Curl_multi_remove_handle-remove a handle resource from the curl batch processing handle.
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-obtain curl-related version information
The function curl_init () initializes a curl session. the unique parameter of the curl_init () function is optional, indicating a url address.
The role of the curl_exec () function is to execute a curl session. the unique parameter is the handle returned by the curl_init () function.
The function curl_close () is used to close a curl session. the only parameter is the handle returned by the curl_init () function.

The above introduces the use of CURL in php to construct POST requests, including some content, and hope to be helpful to friends who are interested in PHP tutorials.
