<?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)); Span class= "hljs-variable" > $context = Stream_context_create (  $opts);  $html = File_get_contents ( ' http ://www.51growup.com/e/admin/test.html ', false,  $context); Echo  $html;?

UrlEncode ($value);$data _string=implode ("&",$values);//Find out which port was needed–if not given use standard (=80) if (!isset ($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"  $data _string. " N $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.51growup.com/‘);curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);$file_contents = curl_exec($ch);curl_close($ch);echo $file_contents;?>
