How to count the inner array count too - php

Question

I have an array like as
$arr[0] = 'summary';
$arr[1]['contact'][] = 'address1';
$arr[1]['contact'][] = 'address2';
$arr[1]['contact'][] = 'country';
$arr[1]['contact'][] = 'city';
$arr[1]['contact'][] = 'pincode';
$arr[1]['contact'][] = 'phone_no';
$arr[2]['work'][] = 'address1';
$arr[2]['work'][] = 'address2';
$arr[2]['work'][] = 'country';
$arr[2]['work'][] = 'city';
$arr[2]['work'][] = 'pincode';
$arr[2]['work'][] = 'phone_no';
Using count($arr) it returns 3 but I also need to count inner array values so it will return 13
What I've tried so far is
function getCount($arr,$count = 0) {
foreach ($arr as $value) {
if (is_array($value)) {
echo $count;
getCount($value,$count);
}
$count = $count+1;
}
return $count;
}
echo getCount($arr);
But its not working as expected

Answer 1

You can use array_walk_recursive for this. This may help -
$tot = 0;
array_walk_recursive($arr, function($x) use(&$tot) {
$tot++;
});
But It is a recursive function so you need to be careful about that.
In that getCount() method you are not storing the count of the array anywhere. So for every call $count is incremented by 1 only.

Answer 2

Simply try this
function getCount($arr, $count = 0) {
foreach ($arr as $value) {
if (is_array($value)) {
$count = getCount($value, $count);
} else {
$count = $count + 1;
}
}
return $count;
}
echo getCount($arr);
What you were doing over here is that you were not storing the value within any variable and that is making an issues with your code as you were on the perfect way

Answer 3

If you need to count only the first two levels, you can do a simple foreach, no need to use a recursive function!:
$count = 0;
foreach( $bigArray as $smallArray ){
if( is_array( $smallArray ) )
$count += count( $smallArray );
else
$count ++;
}

Answer 4

Perhaps I am naive in my approach, but I simply use the sizeof() function. The function's documentation shows that it can take a second argument 1 to tell the function to recursively count multidimensional arrays.
So, to get the 'count' you could simply write sizeof($arr, 1); and it should return 13.
I recognize the value of writing your own function, but doesn't this built-in PHP method solve the problem quite succinctly?
