I often use trim() on *any* incoming data as the first step to sanitizing the data - that gets rid of the whitespace problem you describe. a second step often involves using strval(), intval(), floatval() et al. subsequent steps might involve funcs like striptags() to remove any HTML that some b****** might be trying to XSS your site with. <sidenote> in the future the filter extension will provide robust, standardized ways to santize incoming data - I think it ill be a huge step forward. </sidenote> >
