A %20 character is a space, not a dash. If you type spaces into the address bar the browser will automatically convert them to %20, that is what they are supposed to do. A space is not technically a valid character in a URL, so spaces and other special characters that aren't valid need to be encoded with their hex values. You can use the rawurlencode and rawurldecode functions to encode or decode a string.

After i wrote as folllowing; $subject=rawurldecode($subject); $subject=str_replace(" ","-",$subject); $id=rawurldecode($id); it give me the following result; http://mysite.com/df---tt/%2059/ but i want the format as following; http://mysite.com/df-tt/59/ i just want one sign of the "-", it doesn't matter how many spaces between the variables. and i still could not get rid of the %20 from the id.

I think it's just because your've got space there in your code.

<?phpif(isset($_POST['subject'])){$subject=$_POST['subject'];$id=$_POST['id'];}$subject=trim($subject);$subject=str_ireplace("%20","-",$subject);$id=trim($id);$id=str_ireplace("%20","",$id);?><html><head><meta http-equiv="Refresh" content="0; url=/<?php echo $subject; ?>/<?php echo $id; ?>/"></head><body>Please follow <a href="/<?php echo $subject; ?>/<?php echo $id; ?>/">link</a>!</body></html>

I know it doesn't look like much of a difference, but now there is no space inbetween the "/" and the "<?php".

yes, you are right, i got a spaces between the "/" and "<?php".you almost solve my problem now.at the movement, it give me the result as following, after i copied your code.http://businessfind101.com/re%20re/79/the second place of the id part does what i want, but the second one does not work, and the "$subject=str_ireplace("%20","-",$subject);" seems just suit for one spaces between two words, how about if i got more than 2 words? it will become like "http://businessfind101.com/re--------------re/79/.but i just want the result like "http://businessfind101.com/re-re/79/", it does not matter how many spaces between them.

Ok. Not too sure about that atm. If it's live can you link me to it? otherwise i'd suggest replacing str_ireplace with str_replace and see if that has any effect.

Fixed It Now, in the string the space is stored as " " not "%20". Don't know why i didnt think of this earlier! Sorry! So here is the working version (as far as i know):

<?phpif(isset($_POST['subject'])){$subject=$_POST['subject'];$id=$_POST['id'];}$subject = trim($subject);$subject = str_replace(" ","-",$subject);$id = trim($id);$id = str_replace(" ","",$id);?><html><head><meta http-equiv="Refresh" content="0; url=/<?php echo $subject; ?>/<?php echo $id; ?>/"></head><body>Please follow <a href="/<?php echo $subject; ?>/<?php echo $id; ?>/">link</a>!</body></html>

You could use a regular expression, or you could just write your own loop that will remove more then one dash in a row.

$new_url = "";$found_dash = false;for ($i = 0; $i < strlen($url); $i++){  if ($url[$i] == "-")  {	if ($found_dash)	  continue;	else	  $found_dash = true;  }  else	$found_dash = false;  $new_url .= $url[$i];}

After that, $new_url will contain the URL with excess dashes removed.

The regular expression to match multiple hyphens is pretty trivial: /[-]+/gIn javascript, you could do it like so:

url = url.replace(/[-]+/g, "-");

Someone here could convert that to PHP, I'm sure.

The URL you gave as an example isn't a PHP defined thing. Its an apache thing defined using Mod_Rewrite.

<IfModule mod_rewrite.c>RewriteEngine OnRewriteBase /RewriteCond %{REQUEST_FILENAME} !-fRewriteCond %{REQUEST_FILENAME} !-dRewriteRule ^[a-zA-Z0-9\-]+/[0-9]+/$ yourPage.php?firstVar=$1&second=$2</IfModule>

IfModule code borrowed from WordpressYou would then have to store something in database with the slash-converted variable of the title name or whatever it is you are using. 

<?php$string = "hello  you";//There are 2 spaces next to each other;$string = preg_replace("/(.*)\s+(.*)/i","\\1-\\2",$string);//That should do it;?>

Thanks Jesh;Your one will get the final result as http://www.mysite.com/_how_to_solve_the_problem_.if some string as following; $$ 999 how to **** 00 solve the problem ?????.the final result should like thishttp://www.mysite.com/how_to_solve_the_problemNow i have solved the problem already;
$subject=strtolower($subject);$subject=preg_replace('%^[^a-z]+%', '', $subject);$subject=preg_replace('%[^a-z]+$%', '', $subject);$subject=trim($subject);$subject=preg_replace('%[^a-z]+%', '_', $subject); $id=trim($id);
