从数组/字符串中获取值

Question

How can I fetch the value "3" from this set of arrays:

array(1) { [0]=> string(1) "1" }
array(1) { [0]=> string(1) "3" }
array(1) { [0]=> string(1) "0" } 

The arrays are output from a foreach statement of parenting array, which is:

array(3) { [0]=> string(8) "St" [1]=> string(1) "1" [2]=> string(1) "0" }
array(3) { [0]=> string(16) "Fu" [1]=> string(1) "3" [2]=> string(1) "0" }
array(3) { [0]=> string(13) "Pa" [1]=> string(1) "0" [2]=> string(1) "0" } 

Where I am going for the second line value: "Fu" [1]=> string(1) "3"

Maybe I am doing it wrong from the first array?

You're not giving us much to go on. Are the 3 arrays already in a parent array, in an object, etc.? Below is how to get the # 3 from the 3 arrays...but I'm guessing this is not actually what you are asking, we likely need much more detail...the real problem you are trying to solve.

function getThree($arr1, $arr2, $arr3) {
    $array = array();
    $array[] = $arr1;
    $array[] = $arr2;
    $array[] = $arr3;

    foreach( $array AS $subArray ) {
        // whichever condition works for you
        if( $subArray[0] == 'Fu' || $subArray[1] == 3 ) {
            return $subArray;
        }
    }
}
