php sprintf()是否带有外来字符? [英] php sprintf() with foreign characters?

问题描述

像sprintf一样的接缝对前移字符有问题吗?还是我做错了什么?从字符串中删除像åäö这样的字符时，它似乎可以正常工作.那有必要吗?

Seams to be like sprintf have a problem with foregin characters? Or is it me doing something wrong? Looks like it work when removing chars like åäö from the string though. Should that be necessary?

我希望为报告正确对齐以下几行:

I want the following lines to be aligned correctly for a report:

2011-11-27   A1823    -Ref. Leif  -           12 873,00    18.98
2011-11-30   A1856    -Rättat xx -            6 594,00    19.18

我正在像这样使用sprintf():％-12s％-8s-％-10s-％20s％8.2f

I'm using sprintf() like this: %-12s %-8s -%-10s -%20s %8.2f

使用:php-5.3.23-nts-Win32-VC9-x86

Using: php-5.3.23-nts-Win32-VC9-x86

推荐答案

PHP中的字符串基本上是字节数组(不是字符).它们不能与多字节编码(例如UTF-8)一起在本地使用.

Strings in PHP are basically arrays of bytes (not characters). They cannot work natively with multibyte encodings (such as UTF-8).

有关详细信息，请参见:
https://www.php. net/manual/en/language.types.string.php#language.types.string.details

For details see:
https://www.php.net/manual/en/language.types.string.php#language.types.string.details

PHP中的大多数字符串函数都具有多字节等效项(带有mb_前缀).但是sprintf不会.

Most string functions in PHP have multibyte equivalent though (with the mb_ prefix). But the sprintf does not.

在php.net上函数的文档页面上，有一个用户注释(由"textalk dot com的viktor"提供)具有sprintf的多字节实现.它可能对您有用:
https://www.php.net/manual/en/function. sprintf.php#89020

There's a user comment (by "viktor at textalk dot com") with multibyte implementation of the sprintf on the function's documentation page at php.net. It may work for you:
