Counting an array


ILMV

Recommended Posts

Hello all

 

If I count() this array...

 

array('1','2','3','4');

 

it returns 4, but I want to count this array...

 

array(array('1','2'),array('3','4'));

 

and I want it to return 4, the total number of values within all nested array.

 

Is there a way to do this without having to use a foreach loop?

 

Many Thanks

Also to add..

 

I have tried to use count($arr,COUNT_RECURSIVE); but it would add my original array up to 6, not 4, as it adds the nested arrays as a single value, and then continues to count the array values.

Resolved, I found this :D

 

	function rcount ($array) { 
	$count = 0; 
	if (is_array($array)) { 
		foreach($array as $id=>$sub) { 
			if (!is_array($sub)) {
				$count++; 
			} else { 
				$count = ($count + $this->rcount($sub)); 
			} 
		} 
		return $count; 
	} 
	return FALSE; 
}

I know, what I should have said is 'if possible, without a foreach loop'.

 

Upon research it would appear this if one of the only ways to count the array I have.

 

You could use a for/while loop instead you know, just extra work. But as for being more efficient, doubtful.
