php獲取表單數據的幾種方法：

一、用file_get_contents以get方式獲取內容，需要輸入內容為：

<?php $url='http://www.domain.com/?para=123'; $html = file_get_contents($url); echo $html; ?>

二、用file_get_contents函數，以post方式獲取url，需要輸入內容為：

<?php $url = 'http://www.domain.com/test.php?id=123'; $data = array ('foo' => 'bar'); $data = http_build_query($data); $opts = array ( 'http' => array (     'method' => 'POST',    'header'=> "Content-type: application/x-www-form-urlencodedrn" .         "Content-Length: " . strlen($data) . "rn",     'content' => $data ) ); $ctx = stream_context_create($opts); $html = @file_get_contents($url,'',$ctx); ?>
