I am using laravel 5, I need count the keys available inside every array index suppose for array[0] it has 7 keys, now I need the last key and before last key to compare which's value is bigger. how I can do using loop,as far I have tried.
Please Note The inner keys are stored as object key=>value pair.
foreach ($regions as $regions_key => $regions_value) {
echo sizeof($regions_key)
}
Help is appreciated.
Wouldn't you just count it within your loop:
$total = 0;
foreach($data as $sub_array) {
$total += count($sub_array);
}
After the above iteration is done to find your counts, $total will hold your count.
Try this:
$countArr = array();
foreach ($regions as $regions_key => $regions_value) {
$countArr[$regions_key] = count($regions[$regions_key]); // create array of length of sub array
}
echo max($countArr); // max — Find highest value
To count the number of keys in an array. Try
$arr = Array
(
0 => 'hello',
1 => 'there',
2 => null,
3 => null,
4 => 3,
);
var_dump(count($arr));
$iCount = 0; foreach ($regions as $regions_key => $regions_value) { foreach ($regions_value as $key => $value) { $iCount = count((array)$regions_value); } } echo $iCount;
count(array_keys($arr))$total_keys = count(array_keys($arr)) * count(array_keys($arr[0]))
