本文介绍了ucfirst()函数用于多字节字符编码的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
但是当使用外来字符时,它不会将它们转换为大写,所以我必须使用:
I've asked about strtolower
function. But when using foreign characters it doesn't convert them into uppercase, so I must use:
mb_strtolower($a,"utf8");
但是,如果我想使用 ucfirst / code> function?我没有找到任何类似的函数,其中我可以设置编码类型。
But what can I do, if I want to use
ucfirst()
function? I haven't found any similar function, where I can set encoding type.
推荐答案
mb_ucfirst
函数,正如你已经注意到的。您可以用两个 mb_substr
来伪造 mb_ucfirst
:
There is no mb_ucfirst
function, as you've already noticed. You can fake a mb_ucfirst
with two mb_substr
:
function mb_ucfirst($string, $encoding)
{
$strlen = mb_strlen($string, $encoding);
$firstChar = mb_substr($string, 0, 1, $encoding);
$then = mb_substr($string, 1, $strlen - 1, $encoding);
return mb_strtoupper($firstChar, $encoding) . $then;
}
