Php Form Issue

Hello, I've managed to get a series of javascripts to work exactly as I wanted. They check all and uncheck all checkboxes with a single click of a control checkbox. Unfortunately, the information has to be sent to php. As soon as I add the [] brackets to an input name, the javascript no longer functions. I'll look up a javascript mailing list next, but I figured there must be some other way to get php to recieve the data and convert it to an array. Does anyone have an idea how I can make the php script gather all the multiple &browser=lynx&browser=mosaic&browser=explorer instead of only the last entry? Thanks for any help, Keith
