PHP Count Array Columns

I have this PHP array :

$food = array('fruits' => array('orange', 'banana', 'apple'),
              'veggie' => array('carrot', 'collard', NULL));

if I use this function : 

$rows = count($food);

of course the result will be 2, but how to get number of array columns? so, I'm expecting 3 as a value of fruits and veggie columns. even though veggie has NULL.

$food = array('fruits' => array('orange', 'banana', 'apple'),
              'veggie' => array('carrot', 'collard', NULL));
$array = array_map('count', $food);

You can try This: array_map with count.

<?php 
 $food = array('fruits' => array('orange', 'banana', 'apple'),
        'veggie' => array('carrot', 'collard', NULL));
 $typeTotals = array_map("count", $food);
echo "<pre>";
print_r($typeTotals);

OUTPUT:

Array ( [fruits] => 3 [veggie] => 3 )

You can try this :

$food = array('fruits' => array('orange', 'banana', 'apple'),
                'veggie' => array('carrot', 'collard', NULL));

        echo count($food['fruits']);

However it would only work if you know the element e.g. 'fruits'.

...I mean, if the columns are always the same, then why should we loop it as many as rows?

If the number of columns is always the same and you have at least one element in your $food array you can just probe the first/current element with current()

$columns = count(current($food));

This approach will create an array of counts, by type:

$rows = [];
foreach ($food as $type => $items) {
    $rows[$type] = count($items);
]
