Howdy!

Thanks for taking a look at this.  Can anyone tell me why this regular expression is removing spaces?  I think I've been staring at it for too long or something.

$myvar = preg_replace("/[^a-z\d.,-]/i", "", $myvar);

Thanks in advance!

yes, because the regular expression does removes all that is NOT alpha, decimal, dot, comma, dash.
if you don't want spaces to be removed, you have to add the space into the first part of the expression
