Compare 7-dimensional array in php - php

Question

I have to compare two 7-dimensional Arrays and for every match i have to count +1 to a new array.
This is the array with user-input, which i want to compare with the "right values"
Array([task] => Array(
[OF] => Array(
[nr] => Array(
[1] => Array(
[pos] => Array(
[0] => Array(
[value] => :
)
)
)
[2] => Array(
[pos] => Array(
[0] => Array(
[value] => +
)
)
)
[3] => Array(
[pos] => Array(
[1] => Array(
[value] => -
)
[2] => Array(
[value] => +
)
)
)
[4] => Array(
[pos] => Array(
[0] => Array(
[value] => -
)
)
)
[5] => Array(
[pos] => Array(
[0] => Array(
[value] => *
)
)
)
[6] => Array(
[pos] => Array(
[0] => Array(
[value] => :
)
)
)
[7] => Array(
[pos] => Array(
[0] => Array(
[value] => *
)
)
)
)
)
),
[TA] => Array(
[nr] => Array(
[1] => Array(
[pos] => Array(
[0] => Array(
[value] => :
)
)
)
[2] => Array(
[pos] => Array(
[0] => Array(
[value] => +
)
)
)
[3] => Array(
[pos] => Array(
[1] => Array(
[value] => -
)
[2] => Array(
[value] => +
)
)
)
[4] => Array(
[pos] => Array(
[0] => Array(
[value] => -
)
)
)
[5] => Array(
[pos] => Array(
[0] => Array(
[value] => *
)
)
)
[6] => Array(
[pos] => Array(
[0] => Array(
[value] => :
)
)
)
[7] => Array(
[pos] => Array(
[0] => Array(
[value] => *
)
)
)
)
)
)
The right values are in the same structure with different values.
Now i have to loop through the arrays and check if the user-input is == the "right value".
Sorry if it's hard to understand. It's slightly hard to explain.
Any and all help is appreciated, thank you all in advance.
EDIT:// i want to know the amount of right values of the 'task' arrays e.g. OF => 12 , TA => 3

If I understood well, what you need is a recursive comparision. Here is my adhoc code, I didn't test it:
function compareArrays($array1, $array2) {
$retval = 0;
for($i = 0; $i < count($array1); $i++) {
// The values are arrays, we need a recursive comparation again
if (is_array($array1[$i]) && is_array($array2[$i])) {
$retval += compareArrays($array1[$i], $array2[$i]);
// The values are equal, we can increase the counter
} else if ($array1[$i] === $array2[$i]) {
$retval++;
// The values are different
} else {
// Is there anything to do?
}
}
return $retval;
}
