PHP One-line implementation of the URL steering code

Very low, learn PHP can be done in half an hour.

Reference:

$url =$_get["url"];header ("Location:".) http://". $url);? >

very simple. Ask yourself.
With links: http://bbs.blueidea.com/viewthread.php?tid=2853779
That's the idea of the 5 floor. The file name is saved as viewthread.php, the variable name is TID, the value is 2853779, and the value corresponds to the database call.

Code Expansion php5.2.0 Effective

Reference:

?
$url =$_get["url"];
if (strlen ($url >= ' 3 ')) {
Header ("Location:".) http://". $url);
}
?>

Implementation when the variable value character number is less than three bits, because the short domain name address such as G.cn also has three bits, so do not jump, you can display arbitrary content.

I hope the rookie can use, at least I am on the ~
