Re: newbie question

"1. An optional padding specifier that says what character will be used for padding the results to the right string size. This may be a space character or a 0 (zero character). The default is to pad with spaces. An alternate padding character can be specified by prefixing it with a single quote ('). See the examples below." "3. An optional number, a width specifier that says how many characters (minimum) this conversion should result in." ---- http://au.php.net/manual/en/function.sprintf.php Assume that $price=.65; then the "%0.2f" yields 0.65. If we follow what the manual says, then can you tell me what the 0 is used for? Is it a (optional) paddinng spcifier OR is it a (optional) width specifier OR both? And why does it yiled 0.65 rather than .65?
