编译失败:缺少字符类的终止符 [英] Compilation failed: missing terminating ] for character class

问题描述

$date could be "23/09/2012" or "23-09-2012" or "23\09\2012" 
preg_split('/[\/\-\\]/', $date);

不确定为什么PHP会继续抛出missing terminating ] error吗?

Not sure why PHP keep throw missing terminating ] error?

推荐答案

preg_split('/[\/\-\\]/', $date);
                   ^escaping the closing ']' 

请执行以下操作以消除歧义

Do the following instead, to remove ambiguity

preg_split('/[\/\-\\\\]/', $date);

无需逃避-，但是您也可以使用\-.

There is no need to escape -, but you could use \- as well.

代码:

$date = 'as\sad-s/p';
$slices =  preg_split('/[\/\-\\\\]/', $date);
print_r($slices);

输出:

Array ( [0] => as [1] => sad [2] => s [3] => p )
