在字母和短划线（ - ）php之间获取数字

Question

I have a string that contains a letter, numbers and a dash (-). The numbers represent a specific month and a specific year.

(i.e. 'M4-16' -- April 2016)

I need to break out the 4 by itself and then the 16 by itself. I'm blanking on how to do this right now, so sorry for not including what I've tried.

Thank you in advance!

Since you know the format of the relatively simple string, no regex is needed:

$str = "M4-16";
$parts = explode("-", $str); // Gives ["M4", "16"]
$part1 = substr($parts[0], 1); // Gives 4
$part2 = $parts[1]; // Gives 16
