count array dimensions

[scott212]

Any of you geniuses have any tricks to count the number of dimensions within an array?

I'm using the following to check to see if it is multidimensional or not, but I'd like to convert it

to return the number of dimensions. Here's what I have:

	function array_dimen($input) { // see if the array is multidimensional
	$num_root = count($input);
	$num_branch = count($input, COUNT_RECURSIVE);
	if ($num_root < $num_branch) {
		return 1;
	} else {
		return 0;
	}
}

"Counting elements: Count() and sizeof() count the number of elements in an array. Array_count_values() counts unique values in the array ("set cardinality") and returns an associative array with a frequency table. The unique values from the array will be the keys (indices) for the new array."

 

I got that from this site: <a href="http://www.uri.edu/artsci/com/Logan/teaching/html/com372_spring_2007/html_notes/n3.htm">Here</a>

 

Not sure if counting the elements is the same as counting the dimensions....you can give it a try though.

I'm aware it's been 2 years since this was posted but as I didn't find any solutions for this matter elsewhere I'm happy to upload mine

 

function array_dimen_count($ArrayInput, $dimCount = 0) { // Count an array dimensions
if(is_array($ArrayInput)) {
	return array_dimen_count(current($ArrayInput), $dimCount + 1);
} else {
	return $dimCount;
}
}

 

which can be tested with

$array = array("color" => array("blue", "red", "green"),
               "size"  => array("small", "medium", "large"));
echo 'array size = '. array_dimen_count($array). '<br>';
$array = array("blue", "red", "green", "blue", "blue");
echo 'array size = '. array_dimen_count($array). '<br>';
