How to get the previous url using PHP
Solution 1:
Use the $_SERVER['HTTP_REFERER'] header, but bear in mind anybody can spoof it at anytime regardless of whether they clicked on a link.
Solution 2:
$_SERVER['HTTP_REFERER'] is the answer
Solution 3:
$_SERVER['HTTP_REFERER'] will give you incomplete url.
If you want http://bawse.3owl.com/jayz__magna_carta_holy_grail.php, $_SERVER['HTTP_REFERER'] will give you http://bawse.3owl.com/ only.
Solution 4:
I can't add a comment yet, so I wanted to share that HTTP_REFERER is not always sent.
Notice: Undefined index: HTTP_REFERER
