Personally this is the way that I would build the function:
//Remove array items less than 1
$Values = array_filter($Values,array($this,"callback"));
//Sort the array into descending order 1 - ?
//Find out the total amount of elements in the array
$Count = count($Values);
//Check the amount of remainders to calculate odd/even
if($Count % 2 == 0)
return $Values[$Count / 2];
return (($Values[($Count / 2)] + $Values[($Count / 2) - 1]) / 2);
What changes have I made?
I have used less variables, overwriting the
$Values where needed
Reduced the conditional statements to 1* from 2
Made the code look more readable and understandable.
I have however added a callback, which in turn removes the
if statements but a logical check would have to be used in the callback.Tthe callback would simply be a method in your class like so:
public function callback($value)
return $value > 0;
Unfortunately as the native function
empty is actually a language construct it's not a valid callback; you can however use
return !empty($value); within your callback method to also remove other entities such as
This can be removed as stated, and placed outside the function.
*Notes: I would advise you to have some kind of linear array check to make sure the arrays are based on an integer index, as our code assumes they are, a linear check can be done like so:
if(array_keys($Values) !== range(0,($Count-1)))
This would be added after the
$Count value has come into play.
Example test that I had used to test it was:
$values = array(
which resulted in the correct answer of 5.
