Answer 1

Use HTTP_REFERER which will give you the page from where you came to the current page.

$_SERVER['HTTP_REFERER']

ref: http://php.net/manual/en/reserved.variables.server.php

<?php

// wait 5 seconds and redirect :)
echo "<meta http-equiv=\"refresh\" content=\"5;url=".$_SERVER['HTTP_REFERER']."\"/>";

?>

Answer 2

use window.go(-1);

for details help see http://www.w3schools.com/jsref/met_his_go.asp

Answer 3

Can Be done with Pure javascript

setTimeout(function(){
  window.history.back()
}, 5000);

OR if you want to use php

setTimeout(function(){
  window.location = '<?=$_SERVER['HTTP_REFERER'] ?>'
}, 5000);

Answer 4

You could try redirecting to

sleep(5);
$_SERVER['HTTP_REFERER']
