How to fix   Complexity   

Long Method

Small methods make your code easier to understand, in particular if combined with a good name. Besides, if your method is small, finding a good name is usually much easier.

For example, if you find yourself adding comments to a method's body, this is usually a good sign to extract the commented part to a new method, and use the comment as a starting point when coming up with a good name for this new method.

Commonly applied refactorings include:

Performance Best Practice introduced by
It seems like you are calling the size function count() as part of the test condition. You might want to compute the size beforehand, and not on each iteration.

If the size of the collection does not change during the iteration, it is generally a good practice to compute it beforehand, and not on each iteration:

for ($i=0; $i<count($array); $i++) { // calls count() on each iteration
}

// Better
for ($i=0, $c=count($array); $i<$c; $i++) { // calls count() just once
}
