Regular expressions php split

Question

I need to split a string like '7-2014' into an array [7],[2014] in PHP.

For this special case,

$arr = preg_split('/-/','7-2014'); 

works fine, but how can I make an expression that splits on any of these characters: . / \\ space . / \\ space ?

Answer 1

You can create a character class :

$arr = preg_split('%[-./\\\\ ]%', $subject);

This will split along dashes, dots, slashes, backslashes and spaces.

Answer 2

使用方括号定义多个字符：

$arr = preg_split('#[-\\.\\\\\/ ]#','7-2014');
