Character Filter System Like Wordpress Title Filter

For example when we enter weird characters to wordpress title it converts them so something else.It clears it .
Is there a function like that to clear this characters?

 

Probably something like that should work
preg_replace("(\W)", '_', $str)

 

what is this mean "\W"?

 

You could always take a look into wordpress source code and see exactly what it does

 

I don't know if it emulates the wordpress url but to do automated posting to my wordpress databases I just use ..

$p_title = str_replace(" ","-",strtolower($p_title)) ;
$p_title = ereg_replace("[^A-Za-z0-9\-]", "", $p_title );
$p_title = str_replace("---","-",$p_title) ;

PHP:

then I force that as the 'guid' entry to the db.

The code above switches out spaces " " with dashes "-" then removes any character that's not alphanumeric or a dash. After that I switch "---" out with "-" ... the "---" would occur if the string " - " occurs in the title of something quite frequently.

Yes it's a poorboy hack but it works like a charm, hope it helps.
