I would like to get the array having highest votes.
Highest means the array having highest vote
I have used the following code, but it is not working.
$large=array();
foreach($final2 as $f1){
foreach($final2 as $f2){
if($f1['vote']>$f2['vote'])
$large=$f1;
}
}

AFAIK array size is counted from the number of elements it has.
So may be this will help
$largeArraySize = 0;
foreach($arraylist as $array) {
if(count($array) > $largeArraySize) {
$largeArray = $array;
}
}
// Hence $largeArray has the largest
print_r($largeArray);
Unless a large array come this code will take the first occurrence as the largest.
