Just a quick question monks. I'v been trying this code for a while to count the number of identical elements in the arrays and it keeps returning a number 1 greater then the array length? If I was to test 2 arrays of 10 elements each I get 11 even if only 1 was similar. The arrays contain string elements. 
$MatchCount = 0;

for ($z=0;$z<=$arrLenA;$z++){

    for ($i=0;$i<=$arrLenB;$i++){
   
        if ($sentencesA[$z] eq $setencesB{$i}){
            
            $MatchCount++;
        }
    }
}

print $MatchCount;

Thanks in advance
