php中使用Curl、socket、file_get_contents三种方法POST提交数据_PHP教程

复制代码 代码如下:

/**

* Socket版本

* 使用方法：

* $post_string = "app=socket&version=beta";

* request_by_socket('jb51.net','/restServer.php',$post_string);

*/

function request_by_socket($remote_server,$remote_path,$post_string,$port = 80,$timeout = 30){

$socket = fsockopen($remote_server,$port,$errno,$errstr,$timeout);

if (!$socket) die("$errstr($errno)");

fwrite($socket,"POST $remote_path HTTP/1.0");

fwrite($socket,"User-Agent: Socket Example");

fwrite($socket,"HOST: $remote_server");

fwrite($socket,"Content-type: application/x-www-form-urlencoded");

fwrite($socket,"Content-length: ".strlen($post_string)+8."");

fwrite($socket,"Accept:*/*");

fwrite($socket,"");

fwrite($socket,"mypost=$post_string");

fwrite($socket,"");

$header = "";

while ($str = trim(fgets($socket,4096))) {

$header.=$str;

}

$data = "";

while (!feof($socket)) {

$data .= fgets($socket,4096);

}

return $data;

}

/**

* Curl版本

* 使用方法：

* $post_string = "app=request&version=beta";

* request_by_curl('http://jb51.net/restServer.php',$post_string);

*/

function request_by_curl($remote_server,$post_string){

$ch = curl_init();

curl_setopt($ch,CURLOPT_URL,$remote_server);

curl_setopt($ch,CURLOPT_POSTFIELDS,'mypost='.$post_string);

curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);

curl_setopt($ch,CURLOPT_USERAGENT,"Jimmy's CURL Example beta");

$data = curl_exec($ch);

curl_close($ch);

return $data;

}

/**

* 其它版本

* 使用方法：

* $post_string = "app=request&version=beta";

* request_by_other('http://jb51.net/restServer.php',$post_string);

*/

function request_by_other($remote_server,$post_string){

$context = array(

'http'=>array(

'method'=>'POST',

'header'=>'Content-type: application/x-www-form-urlencoded'."".

'User-Agent : Jimmy's POST Example beta'."".

'Content-length: '.strlen($post_string)+8,

'content'=>'mypost='.$post_string)

);

$stream_context = stream_context_create($context);

$data = file_get_contents($remote_server,FALSE,$stream_context);

return $data;

}
