PHP analog post submission data three ways

The PHP analog post submission data is file_get_contents, curl, and socket, and they can all be submitted via analog post for post data transfer.

File_get_contents Analog Post submission:

$arr =array (' http ' =>array (' method ' = ' POST ', ' content ' = ' name=wang&pwd=123′ ');

$result = file_get_contents ("www.wangzhiguang.com.cn", False,stream_context_create ($arr))

Curl Analog Post submission:

$arr = Array (

Curlopt_returntransfer = True,

Curlopt_header = False,

Curlopt_post = True,

Curlopt_postfields = = Array (' name ' = ' Wang ', ' pwd ' = ' 123′ ')

);

$ch = Curl_init ($url);

Curl_setopt_array ($ch, $arr);

$result = curl_exec ($ch);

Curl_close ($ch);

Socket to simulate post submission:

$url = "www.wangzhiguang.com.cn";

$host = 80;

$content = ' name=wang&pwd=123′;

$fp = Fsockopen ($content, $host, $errno, $ERRSTR);

$length = strlen ($content);

$header = <<

POST {$url} http/1.1

Host: {$host}

content-type:application/x-www-form-urlencoded

Content-length: {$length}

Connection:close

{$content}

HEADER;

Fwrite ($fp, $header);

while (!feof ($fp)) {

$result. = Fread ($FP, 512);

}

$result = Explode ("\r\n\r\n", $result, 2);

Blank line between Connection:close and post data

It is best to return the value $result you can see the sending status.
