    you have to return the integer n such as
    ๐‘›
    3

    (
    ๐‘›
    โˆ’
    1
    )
    3
    +
    (
    ๐‘›
    โˆ’
    2
    )
    3
    +
    .
    .
    .
    +
    1
    3

    ๐‘š
    n
    3
    +(nโˆ’1)
    3
    +(nโˆ’2)
    3
    +...+1
    3
    =m if such a n exists or -1 if there is no such n.

    OP has implemented the logic, it is basically summation of cubes of numbers from 1 to ... until it reaches or surpasses $m

    I agree. I think test cases doesn't cover all. In my first solution I skip lower case everything except first character and I pass it.

    Really like this one! It's have a perfect balance between complexity and simplicity. My only suggestion is maybe make description is more explicit? I was need to read the Wikipedia before start because I don't understand how cypher work. Or maybe it's just me.

    I think this solution is fit perfect for given description. The only one thing which I would correct is implode($arr). There is no need in delimiter at all.

    str_split() is one which I need to remember. Doesn't use it and create arrays from strings in a strange manner.
