Sometimes clients put a dollar sign "$" in a form that only needs a number (like "1.50"). Is there a way to take a post variable and automatically convert it to a float value, stripping off any non-numeric characters? I tried doubleval() without success and I can't use intval() because it has decimals. kind regards,

$SanitizedNumber = ereg_replace('[^0-9.]', '', $NumberString); If you really need to make this a float variable, then you can add $Number = (float)$SanitizedNumber; although in most cases PHP handles type conversion correctly on-the-fly. - steve +--- "They've got a cherry pie there, that'll kill ya" ------------------+
