             if (mysql_num_rows($check)==1)

               $username = $get['user_name'];

RewriteEngine On

RewriteRule^([a-zA-Z0-9_-]+)$ profile.php?u=$1



RewriteRule^([a-zA-Z0-9_-]+)/$ profile.php?u=$1

  • Did you try adding whitespaces between `RewriteRule` and your rewrite rules? – Repox Mar 17 '13 at 20:08
  • I'm using my mobile browser so it's hard to tell, but I think your formatting is wrong there should be a space after rewriterule before the ^ – StrikeForceZero Mar 17 '13 at 20:11
  • yes their is a space between these 2 lines RewriteRule^([a-zA-Z0-9_-]+)$ profile.php?u=$1 RewriteRule^([a-zA-Z0-9_-]+)/$ profile.php?u=$1 – user2172837 Mar 17 '13 at 20:15
  • @user2172837 That's not what you are being asked; there's a big difference between this: `RewriteRule^([a-zA-Z0-9_-]+)$ profile.php?u=$1` and this: `RewriteRule ^([a-zA-Z0-9_-]+)$ profile.php?u=$1` (the last example having a whitespace after `RewriteRule`). – Repox Mar 17 '13 at 20:17
  • @ – Repox sir this the first time i use the .htaccess i do not understand what you are saying can you explain – user2172837 Mar 17 '13 at 20:19

    I did - two times! You need to have a space between `RewriteRule` and `^([a-zA-Z0-9_-]+)$ profile.php?u=$1` in your .htaccess file. A space - the long button in the bottom of your keyboard. – Repox Mar 17 '13 at 20:27
  • off topic, but it's worth knowing that the `mysql_xx()` functions are deprecated. If at all possible, I recommend switching to the `mysqli` or `PDO` libraries instead. – Spudley Mar 17 '13 at 20:32
  • you probably need a rewritecond on the {REQUEST_URI} – Sebas Mar 17 '13 at 20:55
  • @ Repox i have a space between RewriteRule and ^([a-zA-Z0-9_-]+)$ profile.php?u=$1 but still having error and the folder is still hiding – user2172837 Mar 17 '13 at 21:07

Do not save your .htaccess file in UTF8 charcter encoding. save it in ANSI

  • why would you do such a thing, i've always used utf-8 without any problem – Sebas Mar 17 '13 at 20:54
  • @Sebas I had experience about it. perhaps some apache servers have problem with it. – Amir Mar 17 '13 at 20:56
  • mmm so how to solve this is that any tutorial that i use it ?? be cause until now i did not get success with this error – user2172837 Mar 17 '13 at 21:01
  • @user2172837, just save it in ANSI mode.hope this solve your problem. you can use windows `Notepad` and then save as, then select ANSI – Amir Mar 17 '13 at 21:04
  • @Amir still the same error .. does the place of the file must be in some specific path or no because the folder that hold .htaccess it is hidding and i can not choose it – user2172837 Mar 17 '13 at 21:16
  • @user2172837, it usually should be in root – Amir Mar 17 '13 at 21:17
  • it is in the root folder and this folder and not appear as it is hide – user2172837 Mar 17 '13 at 21:25
  • thank you AMIR you saved me but it do not make any sense what is the difference between the type of encoding ?? – user2172837 Mar 17 '13 at 21:28
  • @user2172837, There is some explanation about difference http://stackoverflow.com/questions/700187/unicode-utf-ascii-ansi-format-differences Also you can google it...some hiding characters cause server to error – Amir Mar 17 '13 at 21:32

Assuming that profile.php has no errors. Try to delete your last line of the .htaccess file. Also add a space between Rewriterule and '^'. Adding whitespace to the regex has nothing do to with this, because of the ctype_alnum() function. This only permits alphabetic characters.

Just copy and pase this to your .htaccess file and (ofcourse) delete the previous lines:

RewriteEngine On
RewriteRule ^([a-zA-Z0-9_-]+)$ profile.php?u=$1
