Deleting spaces of a string

[axmug]

I'm trying deleting spaces of a string and once deleted I want to obtain a new string with _ instead of spaces. For example: I have a string with the value Matrix Revolutions and I want to obtain an string like Matrix_Revolutions. I can obtain an array with both values: Matrix and Revolutions. The problem is to get the string Matrix_Revolutions. I don't know how to do it. I have tried the following:

$dname=explode(" ",$cat); //it works ok
$cat=$dname[0]+"_"+$dname[1]; //it doesn't work. $cat value is 0.

How can I do it?
Thanks.

Why not just use str_replace()? (

$dbname = (' ', '_', $cat);

axmug,

Just use the reverse function to explode, called ...you've guessed it now: explode(). Like this:

$dname=explode(" ",$cat);
$d_name = implode("_", $dname);

Good luck §;O)
