使用php模拟post传值虽然在日常生活中用到的不是很多，但是在某些场合还是经常用到的。下面脚本之家小编给大家整理了三种php模拟post传值的方法，file_get_contents、curl和socket，需要的朋友参考下

第一种：file_get_contents来模拟post

     
       array(‘method‘=>‘POST‘,‘content‘=> http_build_query($post),),);$result = file_get_contents($url,false, stream_context_create($options));return $result;}$data = file_get_contents_post("http://www.a.com/post/post.php", array(‘name‘=>‘caiknife‘,‘email‘=>‘caiknife#gmail.com‘));var_dump($data);
     

第二种：curl模拟post

     
      true,CURLOPT_HEADER =>false,CURLOPT_POST =>true,CURLOPT_POSTFIELDS => $post,);$ch = curl_init($url);curl_setopt_array($ch, $options);$result = curl_exec($ch);curl_close($ch);return $result;}$data = curl_post("http://www.a.com/post/post.php", array(‘name‘=>‘caiknife‘,‘email‘=>‘caiknife#gmail.com‘));var_dump($data);
     

第三种：socket来模拟post

     
      POST {
   $urls[‘path‘]} HTTP/1.1
      Host:{
   $urls[‘host‘]}
      Content-Type: application/x-www-form-urlencoded
      Content-Length:{
   $length}
      Connection: close
      {
   $post}
      HEADER;fwrite($fp, $header);$result =‘‘;while(!feof($fp)){$result .= fread($fp,512);}$result = explode("\r\n\r\n", $result,2);return $result[1];}$data = socket_post("http://www.a.com/post/post.php", array(‘name‘=>‘caiknife‘,‘email‘=>‘caiknife#gmail.com‘));var_dump($data);
     

上面这三种方法最后看到的内容都是一样的，都可以得到post的传值；但是在是用socket的时候，发送header信息时必须要注意header的完整信息，比如content type和content length必须要有，connection: close和post数据之间要空一行，等等；而通过socket取得的内容是包含了header信息的，要处理一下才能获得真正的内容。

下面给大家说下php模拟post提交请求，调用接口 

/*** 模拟post进行url请求* @param string $url* @param string $param*/function request_post($url = '', $param = '') {if (empty($url) || empty($param)) {return false;}$postUrl = $url;$curlPost = $param;$ch = curl_init();//初始化curlcurl_setopt($ch, CURLOPT_URL,$postUrl);//抓取指定网页curl_setopt($ch, CURLOPT_HEADER, 0);//设置headercurl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//要求结果为字符串且输出到屏幕上curl_setopt($ch, CURLOPT_POST, 1);//post提交方式curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost);$data = curl_exec($ch);//运行curlcurl_close($ch);return $data;}

这是方法，

下面是具体的调用案例。

function testAction(){$url = 'http://mobile.jschina.com.cn/jschina/register.php';$post_data['appid'] = '10';$post_data['appkey'] = 'cmbohpffXVR03nIpkkQXaAA1Vf5nO4nQ';$post_data['member_name'] = 'zsjs123';$post_data['password'] = '123456';$post_data['email'] = 'zsjs123@126.com';$o = "";foreach ( $post_data as $k => $v ) { $o.= "$k=" . urlencode( $v ). "&" ;}$post_data = substr($o,0,-1);$res = $this->request_post($url, $post_data); print_r($res);}

这样就提交请求，并且获取请求结果了。一般返回的结果是json格式的。

这里的post是拼接出来的。

也可以改造成下面的方式。

/*** 模拟post进行url请求* @param string $url* @param array $post_data*/function request_post($url = '', $post_data = array()) {if (empty($url) || empty($post_data)) {return false;}$o = "";foreach ( $post_data as $k => $v ) { $o.= "$k=" . urlencode( $v ). "&" ;}$post_data = substr($o,0,-1);$postUrl = $url;$curlPost = $post_data;$ch = curl_init();//初始化curlcurl_setopt($ch, CURLOPT_URL,$postUrl);//抓取指定网页curl_setopt($ch, CURLOPT_HEADER, 0);//设置headercurl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//要求结果为字符串且输出到屏幕上curl_setopt($ch, CURLOPT_POST, 1);//post提交方式curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost);$data = curl_exec($ch);//运行curlcurl_close($ch);return $data;}

将拼接也封装了起来，这样调用的时候就更简洁了。

function testAction(){$url = 'http://mobile.jschina.com.cn/jschina/register.php';$post_data['appid'] = '10';$post_data['appkey'] = 'cmbohpffXVR03nIpkkQXaAA1Vf5nO4nQ';$post_data['member_name'] = 'zsjs124';$post_data['password'] = '123456';$post_data['email'] = 'zsjs124@126.com';//$post_data = array();$res = $this->request_post($url, $post_data); print_r($res);}
