This article describes three methods and sample code for php to send a post request. Use curl, file_get_content, and fsocket to submit data in post mode.

Php uses curl, file_get_content, and fsocket to send post data.

Instance code:

Sample Code:

　　

// Send post request data

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) {// file_get_content

// Www.jbxue.com

$ 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 $ query ";

$ H = fsockopen ($ host, 80 );

Fwrite ($ h, $ post );

For ($ a = 0, $ r = '';! $ ;){

$ B = fread ($ h, 8192 );

$ R. = $ B;

$ A = ($ B = '')? 1-0 );

}

Fclose ($ h );

Return $ r;

}

}
