Question

I need to create a bunch of feeds in a fixed width format, they re all relatively the same in layout, but they can all have different formats.

例如:

Field 1 can be 30 bytes wide, left justified and padded with 0s
Field 2 can be 20 bytes wide, right justified padded with spaces

我只想在行文中储存地板的参数,但不知道储存地板——类型参数的最佳方式,因为其固定不变,我可以重新阅读:

$field = str_pad($input, $width, $pad_string, $pad_type)

我可以把<代码>eval(>)围绕<代码>$pad_type,但似乎只是草图。

是否有更好的办法这样做?

I muck with, PHP 5.0, MySQL 4
