方法一：用fopen()打开url
<?php
$fp = fopen($url, ‘r');
stream_get_meta_data($fp);
while(!feof($fp))
{
$result .= fgets($fp, 1024);
}
echo “url body: $result”;
fclose($fp);
?>方法二：用file_get_contents()
<?php
$url='https://www.adminn.cn/';
$html = file_get_contents($url);
echo $html;
?>方法三：用fsockopen()函数打开url，fsockopen()函数需要 PHP.ini 中 allow_url_fopen 选项开启。
<?php
function get_url ($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/1.1rn”;
$request .= “Host: $url[host]rn”;
$request .= “Connection: Closern”;
if($cookie) $request.=”Cookie: $cookien”;
$request.=”rn”;
fwrite($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,”rnrn”);
$body=substr($body,4,strlen($body));
return $body;
}
return false;
}
