I have been trying to count the last leaf node elements in a array. Im thinking along the lines of:
- Getting a simple array of leaf elements from the testArray using: 'array_walk_recursive'.
- Count elements in the new array using: 'array_count_values'.
Im unsure how to get a simple list array from 'array_walk_recursive', i just get a long string of values....or is there a better way of achieving this result?
DESIRED RESULT:
flammable = 1
irritant = 2
toxic = 3
PHP:
$testArray = Array
(
[0] => Array
(
[0] => toxic
[1] => irritant
[3] => flammable
)
[1] => Array
(
[0] => toxic
[1] => irritant
)
[2] => Array
(
[0] => toxic
)
);
array_walk_recursive($testArray, function(&$value)
{
echo 'string = '.$value;
print_r(newArray); //How can i get this new array list?
});
$counts = array_count_values($newArray); //and use this to count values?
