Answer 1

Use the function array_filter with an anonymous function to return items containing the desired value.

Examples

If the value "Yes" is always in position 2 of the sub-line:

$novoArray = array_filter($seuArray, function($arr) {
    return $arr[2] == 'Sim';
})

If you are in any position:

$novoArray = array_filter($seuArray, function($arr) {
    return in_array('Sim', $arr);
});
