如何利用php发送get请求

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;

}

?>
