Cut out the?????

[Anon]

Hi,

I'm having a few problems on working out how to do this. (PHP)

My script gets passed a search varaible which is typed in by the user.

The script returns something like;

books+cars+hotrods

This then needs to be converted to a variable I can uses as a file reference - which can be done by str_replace ("+","/" $variable);

however: I can't work out how to change the incoming variable to the correct format if the input is something like:

+books++++++cars+++hotrods++

Anyone know how I can always convert something like the above to:

books/cars/hotrods

Can it be done without using regex??

Cheers!!

And why not with regexp ?

$s=ereg_replace("[+]+","/",$s);
//Remove first /
if($s[0]=="/")
$s=substr($s,1);
//Remove last /
if(substr($s,-1)=="/")
$s=substr($s,0,-1);
