Three common uses of PHP analog post requests

This article mainly introduces the PHP analog POST request Three common uses, the interest friend's reference, hoped to be helpful to everybody.

The example in this paper describes how PHP implements a simulated post request, as follows:

Class request{public static function post ($url, $post _data = ", $timeout = 5) {//curl $ch = Curl_init ();  curl_setopt ($ch, Curlopt_url, $url);  curl_setopt ($ch, Curlopt_post, 1);  if ($post _data! = ") {curl_setopt ($ch, Curlopt_postfields, $post _data);   } curl_setopt ($ch, Curlopt_returntransfer, 1);  curl_setopt ($ch, Curlopt_connecttimeout, $timeout);  curl_setopt ($ch, Curlopt_header, false);  $file _contents = curl_exec ($ch);  Curl_close ($ch); return $file _contents;     public static function Post2 ($url, $data =array ()) {//file_get_content $postdata = http_build_query ($data); $opts = Array (' http ' = = Array (' method ' = ' + ' POST ', ' header ' = ' + ' content-type:application/x-www-     form-urlencoded ', ' content ' = $postdata));  $context = Stream_context_create ($opts);   $result = File_get_contents ($url, False, $context); return $result; public static function Post3 ($host, $path, $query, $others = ") {//fsocket $post =" Post $path http/1.1\r\nhost: $host \ r \ n ";  $post. = "content-type:application/x-www-form-";  $post. = "Urlencoded\r\n${others}";  $post. = "User-agent:mozilla 4.0\r\ncontent-length:"; $post. =strlen ($query). "  \r\nconnection:close\r\n\r\n$query ";  $h =fsockopen ($host, 80);  Fwrite ($h, $post); For ($a =0, $r = ";!    $a;) {$b =fread ($h, 8192);    $r. = $b;   $a = (($b = = ")? 1:0);  } fclose ($h); return $r; }} $url = ' http://******/con/inter.php '; $data =request::p ost ($url, Array (' API ' = ' tag_list ')); $data 2=request:: Post2 ($url, Array (' API ' = ' tag_list '); Echo $data;
