number_format problem (?)

Hi all. Not specifically php4 - to my knowledge this is the same in php3 - but while you're at it, here's one for the suggestion box... number_format has one problem (at least I find it a problem)... the third and fourth parameters, (decimal point and thousands separator) don't recognize an empty string: $n = 1234.123 echo number_format ($n, 2, '.', ''); ...outputs "1,234.12" It would be much more useful if it were possible to distinguish between an argument not passed at all and an argument passed an empty string. Thanks, Alex - - - - - - - - - - Alexander Fordyce alex@ax-im.com
