The PHP manual is vague in several sections. I wonder how bug reports get submitted for it? The optional specifiers to the left of the decimal place have a psuedo last-to-first precedence. For example: $price = .65; printf("'%8.2f'\n", $price); -> ' 0.65' This shows that there are 8 characters reserved for the number to the left of the decimal. Therefore, '8' is the width specifier. printf("'%-8.2f'\n", $price); -> '0.65 ' printf("'%08.2f'\n", $price); -> '00000000.65' printf("'%0-8.2f'\n", $price); -> '0.650000000' -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
