Performance Best Practice introduced by
It seems like you are calling the size function sizeof() 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
}

This code seems to be duplicated across your project.

Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation.

You can also find more detailed suggestions in the “Code” section of your repository.
