document.write not returning string

Question

i want to get the string after # tag in url with php. but there is no function to find it. so i get it by the javascript on the same page and call that variable into php by

  <script>
  var query = location.href.split('#');
  var a =  String(query[1]);
  </script>          

  <?php 
     $variable = "<script>document.write(a)</script>"; 
     print_r (explode("%",$variable));
  ?>

but this code print the string as it is and it doesn't split by %.

gives the result like Array ( [0] => z%a ) for this link http://immersed.in/CodeIgniter/#z%a

please help what to do

@Daan but it's not actually explode the url. if i check with storing manual static link then it explodes but if i run above code.. it gives whole string as it is — Meet Vora, Mar 16 '15 at 12:20

"but this code prints the string as it is and it doesn't split by %.?"

<?php 
     $variable = "<script>document.write(a)</script>"; 
     print_r (explode("%",$variable));
 ?>

Yes the compiler (interpreter) is right!, because when you say $variable = "<script>document.write(a)</script>"; the variable $variable is a string variable because you have <script></script> does not mean that it will be execute as js script for two reasons:

Your script is under quote
Even though you put it out of quote it wont work because you are on the server side ( on php code..) it will not execute till your code comes to the client side ( browser)

Also trying this wont work:
explode('#', $url);

because url part after the # is not sent to the server. here

Also it might be helpful to read about client side vs server side langs.

sorry to asking help again. but i write this http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI] and it don't send me the value after # tag. also there is a comment "This function does not include username:password from a full URL or the fragment (hash)." – Meet Vora Mar 17 '15 at 03:09

You cannot get hash tag using php. And javascript will run on client side and php will run on server side. Refer to this links. Similar answer : Getting FULL URL with #tag,
