convert PHP array values from string to integer

i am beginner in 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’s 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

>Solution :

You need a capture group for just the number. See:

preg_match_all("/<td>([0-9]{1,2}\.[0-9]{2})<\/td>/",'<td>10.00</td><td>22.33</td>',$matches);
foreach($matches[1] as $match){
    echo (int)$match; 
}

Although you are seeing:

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

Your array really has HTML still in it, so it is:

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

casting that to an int won’t work. So capturing the inner value via regex is a better approach. Alternatively strip_tags could be used.
