Php gets the URL address of the previous page of the current page, that is, the page from which the current page is linked, you can use $_ SERVER ['HTTP_REFERER']
But $_ SERVER ['HTTP_REFERER'] can also be forged and deceived. There are three ways to forge and deceive $_ SERVER [' HTTP_REFERER']
Note: window platform uses phpstudy integrated environment nginx this method is invalid, apache is normal, other platforms are not tested
The first method: file_get_contents
$url = "http://localhost/test/test.php";$refer="http://www.aa.com";$opt=array('http'=>array('header'=>"Referer: $refer"); $context=stream_context_create ($opt); $file_contents = file_get_contents ($url,false, $context); echo $file_contents
Stream_context_create in file_get_contents forges important parameters of the source.
The second method: CURL
$url = "http://localhost/test/test.php"; / / requested page address $refer=" http://www.aa.com"; / / fake page address $ch = curl_init (); curl_setopt ($ch, CURLOPT_URL,$url); curl_setopt ($ch, CURLOPT_REFERER,$refer); curl_exec ($ch); curl_close ($ch)
The third method: fsockopen
$url= "http://localhost/test/test.php";$target =" http://www.manongjc.com/";/** sockopen forged website source address * @ parem $url page address to be accessed * @ parem $target fake source page * @ parem $port website port default 80 * @ parem page script execution time defaults 30 s * / function referer ($url,$target,$port=80,$t=30) {$info=parse_url ($url) $fp = fsockopen ($info ["host"], $port, $errno, $errstr, $t); if (! $fp) {echo "$errstr ($errno)" .PHP _ EOL;} else {$out = "GET". $info ['path']. " HTTP/1.1 ".PHP _ EOL; $out. =" Host: ". $info [" host "]. PHP_EOL; $out. =" Referer: ". $target.PHP_EOL; $out. =" Connection: Close ".PHP _ EOL; $out. = PHP_EOL; fwrite ($fp, $out); while (! feof ($fp)) {echo fgets ($fp) / / send head request header information} fclose ($fp);}} / / function call referer ($url,$target)
