php取得表單資料的幾個方法：
#一、用file_get_contents以get方式取得內容，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方式取得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);
$opts = array (
'http' => array (
'method' => 'POST',
'header'=> "Content-type: application/x-www-form-urlencoded\r\n" .
"Content-Length: " . strlen($data) . "\r\n",
'content' => $data
)
);
$ctx = stream_context_create($opts);
$html = @file_get_contents($url,'',$ctx);

#三、用fopen開啟url，以get方式取得內容，需要輸入內容為：
<?php
$fp = fopen($url, 'r');
$header = stream_get_meta_data($fp);//获取信息
while(!feof($fp)) {
$result .= fgets($fp, 1024);
}
echo "url header: {$header} <br>":
echo "url body: $result";
fclose($fp);
?>四、用fopen開啟url，以post方式取得內容，需要輸入內容為：
<?php $data = array ('foo2' => 'bar2','foo3'=>'bar3'); $data = http_build_query($data); $opts = array ( 'http' => array ( 'method' => 'POST', 'header'=> "Content-type: application/x-www-form-urlencoded\r\nCookie:cook1=c3;cook2=c4\r\n" . "Content-Length: " . strlen($data) . "\r\n", 'content' => $data ) ); $context = stream_context_create($opts); $html = fopen('http://www.test.com/zzzz.php?id=i3&id2=i4','rb' ,false, $context); $w=fread($html,1024); echo $w; ?>
五、用fsockopen函數開啟url，以get方式取得完整的數據，包括header和body，需要輸入內容為：
?php
function get_url ($url,$cookie=false)
{
$url = parse_url($url);
$query = $url[path]."?".$url[query];
echo "Query:".$query;
$fp = fsockopen( $url[host], $url[port]?$url[port]:80 , $errno, $errstr, 30);
if (!$fp)
{return false;
} else {
$request = "GET $query HTTP/1.1\r\n";
$request .= "Host: $url[host]\r\n";
$request .= "Connection: Close\r\n";
if($cookie) $request.="Cookie: $cookie\n";
$request.="\r\n";
fwrite($fp,$request);
while(!@feof($fp)) {
$result .= @fgets($fp, 1024);
}
fclose($fp);
return $result;
}
}
//获取url的html部分，去掉header
function GetUrlHTML($url,$cookie=false)
{
$rowdata = get_url($url,$cookie);
if($rowdata)
{
$body= stristr($rowdata,"\r\n\r\n");
$body=substr($body,4,strlen($body));
return $body;
}
return false;
}
