从PHP中的字符串返回多个整数

Question

I am trying to return the numbers from a string as separate integers. The string has the following markup:

$string = "20 x 20 cm";

The number 20 could be a larger number as well. e.g. 70 x 93 cm or 120 x 230 cm, so it isn't always equal to each other.

I've read about Preg_Match, but couldn't figure it out. So now I'm here asking for your help.

Thanks in advance!

Answer 1

You could use

$string = '20 x 20 cm';
$arr = explode(' ', $string);
$arr = array($arr[0], $arr[2]);
print_r($arr);
