Convert PHP array values from string to integer [duplicate]

Question

I am new to PHP. I used curl and regex to get all the number with a certain pattern from an HTML table like this:

preg_match_all("/<td>[0-9]{1,2}\.[0-9]{2}<\/td>/m",$result,$match);
print_r($match);

This is the result array: ($match)

Array ( [0] => Array ( [0] => 10.00 [1] => 10.00 [2] => 10.00 [3] => 1.00 [4] => 12.00 ) )

All the values are strings, I need them as integers. How to do that? I tried this solution, but it gives 0 as an integer (was 10.00). Is it because it's an array inside array?

$test = $match[0][1];
$test2 = (int)$test;
echo $test2
