How get post url in php?

function pc_post_request[$host,$url,$content=''] {
    $timeout = 2;
    $a = array[];
    if [is_array[$content]] {
        foreach [$content as $k => $v] {
            array_push[$a,urlencode[$k].'='.urlencode[$v]];
        }
    }
    $content_string = join['&',$a];
    $content_length = strlen[$content_string];
    $request_body = "POST $url HTTP/1.0
Host: $host
Content-type: application/x-www-form-urlencoded
Content-length: $content_length

$content_string";

    $sh = fsockopen[$host,80,&$errno,&$errstr,$timeout]
        or die["can't open socket to $host: $errno $errstr"];

    fputs[$sh,$request_body];
    $response = '';
    while [! feof[$sh]] {
        $response .= fread[$sh,16384];
    }
    fclose[$sh] or die["Can't close socket handle: $php_errormsg"];

    list[$response_headers,$response_body] = explode["\r\n\r\n",$response,2];
    $response_header_lines = explode["\r\n",$response_headers];
        
    // first line of headers is the HTTP response code
    $http_response_line = array_shift[$response_header_lines];
    if [preg_match['@^HTTP/[0-9]\.[0-9] [[0-9]{3}]@',$http_response_line,
                   $matches]] {
        $response_code = $matches[1];
    }

    // put the rest of the headers in an array 
    $response_header_array = array[];
    foreach [$response_header_lines as $header_line] {
        list[$header,$value] = explode[': ',$header_line,2];
        $response_header_array[$header] = $value;
    }
    
    return array[$response_code,$response_header_array,$response_body];
}

In this article, we will know what HTTP GET and POST methods are in PHP, how to implement these HTTP methods & their usage, by understanding them through the examples.

The Hypertext Transfer Protocol [HTTP] is designed to enable communications between clients and servers. HTTP works as a request-response protocol between a client and server. A web browser may be the client, and an application on a computer that hosts a website may be the server. A client [browser] submits an HTTP request to the server; then the server returns a response to the client. The response contains status information about the request and may also contain the requested content.

There are 2 HTTP request methods:

• GET: Requests data from a specified resource.
• POST: Submits data to be processed to a specified resource.

We will understand both these methods in detail through the examples.

GET Method: In the GET method, the data is sent as URL parameters that are usually strings of name and value pairs separated by ampersands [&]. In general, a URL with GET data will look like this:

Example: Consider the below example:

//www.example.com/action.php?name=Sam&weight=55 

Here, the bold parts in the URL denote the GET parameters and the italic parts denote the value of those parameters. More than one parameter=value can be embedded in the URL by concatenating with ampersands [&]. One can only send simple text data via GET method.

Example: This example illustrates the HTTP GET method in PHP.
