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。
第一种:file_get_contents来模拟post
function file_get_contents_post($url, $post){ $options = array( 'http'=> array( 'method'=>'POST', 'content'=> http_build_query($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
function curl_post($url, $post){ $options = array( CURLOPT_RETURNTRANSFER =>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
function socket_post($url, $post){ $urls = parse_url($url); if(!isset($urls['port'])){ $urls['port']=80; } $fp = fsockopen($urls['host'], $urls['port'], $errno, $errstr); if(!$fp){ echo "$errno, $errstr"; exit(); } $post = http_build_query($post); $length = strlen($post); $header =<< POST {$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。
