If you want to get the value after the hash mark or anchor as shown in a user s browser  This isn t possible with  standard  HTTP as this value is never sent to the server  hence it won t be available in   SERVER  REQUEST URI   or similar predefined variables   You would need some sort of JavaScript magic on the client side  e g  to include this value as a POST parameter   If it s only about parsing a known URL from whatever source  the answer by mck89 is perfectly fine though

You need to parse the url first  so it goes like this    url    https   www example com profile picture    fragment   parse url  url PHP URL FRAGMENT     this variable holds the value -  picture    If you need to parse the actual url of the current browser  you need to request to call the server    url     SERVER  REQUEST URI     fragment   parse url  url PHP URL FRAGMENT     this variable holds the value -  picture

I ve been searching for a workaround for this for a bit - and the only thing I have found is to use URL rewrites to read the  anchor    I found in the apache docs here http   httpd apache org docs 2 2 rewrite advanced html the following        By default  redirecting to an HTML anchor doesn t work  because mod rewrite escapes the   character  turning it into  23    This  in turn  breaks the redirection       Solution  Use the  NE  flag on the RewriteRule  NE stands for No   Escape       Discussion  This technique will of course also work with other special   characters that mod rewrite  by default  URL-encodes    It may have other caveats and what not     but I think that at least doing something with the   on the server is possible

Getting the data after the hashmark in a query string is simple  Here is an example used for when a client accesses a glossary of terms from a book  It takes the name anchor delivered   tesla   and delivers the client to that term and highlights the term and its description in blue so its easy to see   A  setup your strings with a div id  so the name anchor goes where its supposed to and the javascript can change the text colors    lt div id  tesla  gt Tesla lt  div gt   lt div id  tesla1  gt An energy company lt  div gt    B  Use Javascript to do the heavy work  on the server side  inserted in your PHP page  or wherever     lt script src  http   code jquery com jquery-1 9 1 min js  gt  lt  script gt    C  I am launching the java function automatically when the page is loaded     lt script gt     document   ready function       D  get the anchor   tesla  from the url received by the server  var myhash1     location  attr  hash      myhash1     tesla   E  trim the hash sign off of it   myhash1   myhash1 substr 1     myhash1    tesla   F  I need to highlight the term and the description so i create a new var   var myhash2    1   myhash2   myhash1 concat myhash2     myhash2    tesla1   G  Now I can manipulate the text color for the term and description  var elem   document getElementById myhash1   elem style color    blue   elem   document getElementById myhash2   elem style color    blue        lt  script gt    H  This works  client clicks link on client side  xyz com tesla  and goes right to the term  the term and the description are highlighted in blue by javascript for quick reading    all other entries left in black

You can do it by a combination of javascript and php    lt div id  cont  gt  lt  div gt    And by the other side    lt script gt  var h   window location hash  var h1    win substr 1     string with no   var q1     lt input type  text  id  hash  name  hash  value    h1    gt     setInterval function    if win1        document querySelector   cont   innerHTML   q1    else alert  Something went wrong     1000    lt  script gt    Then  on form submit you can retrieve the value via   POST  hash    set the form
