方法1: 用file_get_contents 以get方式獲取內容

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

方法2: 用fopen打開url, 以get方式獲取內容

<?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3：用file_get_contents函數,以post方式獲取url

<?php
$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' => $data
)
);$context = stream_context_create($opts);
$html = file_get_contents('http://localhost/e/admin/test.html', false, $context);echo $html;
?>

方法4：用fsockopen函數打開url，以get方式獲取完整的數據，包括header和body,fsockopen需要 PHP.ini 中 allow_url_fopen 選項開啟

<?phpfunction 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 $result;}}//獲取url的html部分，去掉headerfunction GetUrlHTML($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;}
?>

方法5：用fsockopen函數打開url，以POST方式獲取完整的數據，包括header和body

<?php
function HTTP_Post($URL,$data,$cookie='', $referrer=""){// parsing the given URL$URL_Info=parse_url($URL);// Building referrerif($referrer=="") // if not given use this script as referrer$referrer="111";// making string from $dataforeach($data as $key=>$value)$values[]="$key=".urlencode($value);$data_string=implode("&",$values);// Find out which port is needed - if not given use standard (=80)if(!isset($URL_Info["port"]))$URL_Info["port"]=80;// building POST-request:$request.="POST ".$URL_Info["path"]." HTTP/1.1\n";$request.="Host: ".$URL_Info["host"]."\n";$request.="Referer: $referrer\n";$request.="Content-type: application/x-www-form-urlencoded\n";$request.="Content-length: ".strlen($data_string)."\n";$request.="Connection: close\n";$request.="Cookie:?? $cookie\n";$request.="\n";$request.=$data_string."\n";$fp = fsockopen($URL_Info["host"],$URL_Info["port"]);fputs($fp, $request);while(!feof($fp)) {$result .= fgets($fp, 1024);}fclose($fp);return $result;
}
?>

方法6:使用curl庫，使用curl庫之前，可能需要查看一下php.ini是否已經打開了curl擴展

<?php
$ch = curl_init();
$timeout = 5;
curl_setopt ($ch, CURLOPT_URL, 'http://www.domain.com/');
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents = curl_exec($ch);
curl_close($ch);echo $file_contents;
?>
