Method 1: Use file_get_contents to get the content in the Get mode:


?
<?php
$html = file_get_contents($url);
echo $html;
?>


Method 2: Open the URL with fopen and get the content in get:


<?php
$fp = fopen($url, ‘r');
stream_get_meta_data($fp);
while(!feof($fp)) {
$result .= fgets($fp, 1024);
}
echo “url body: $result”;
fclose($fp);
?>


Method 3: Use the file_get_contents function to get the URL by post


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

Method 4: Open the URL with the Fsockopen function, get the complete data in Get mode, including header and Body,fsockopen need php.ini allow_url_fopen option to open



<?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;
}
?>


Method 5: Use the Fsockopen function to open the URL, post to get the full data, including header and body


<?php
function HTTP_Post($URL,$data,$cookie, $referrer=”")
{
 
// parsing the given URL
$URL_Info=parse_url($URL);
 
// Building referrer
if($referrer==”") // if not given use this script as referrer
$referrer=”111″;
 
// making string from $data
foreach($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/1.1n”;
$request.=”Host: “.$URL_Info["host"].”n”;
$request.=”Referer: $referern”;
$request.=”Content-type: application/x-www-form-urlencodedn”;
$request.=”Content-length: “.strlen($data_string).”n”;
$request.=”Connection: closen”;
 
$request.=”Cookie:  $cookien”;
 
$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;
}
 
?>

Method 6: Using the Curl Library, before using the Curl Library, you may need to see if php.ini has the curl extension turned on


<?php
$ch = curl_init();
$timeout = 5;
curl_setopt ($ch, CURLOPT_URL, ‘http://www.jb51.net/');
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents = curl_exec($ch);
curl_close($ch);
 
echo $file_contents;
?>
