IPv4 Integer Conversion Function You can remove the spaces around your first '='. However, your main problem is int overflow ;). Remember, an IP address takes up 4 full bytes. |

Calculate ISBN-13 check digit Exactly the approach I took in my C# answer. Seems PHP is ~9 characters more efficient! |

The Luhn algorithm for verifying credit card numbers, etc. It's a good idea, and an interesting approach, but it doesn't appear to work. At least not with my few tests. It looks like the "i" in your first lambda is supposed to be the index of the character in the string. Does that work as it should? If so, why do you reverse the string only to then modify it based on index position? Seems a bit redundant, no? |

Shortest Floor Function Why <=x-1? would <x not be exactly the same thing, but 3 characters shorter? |

Shortest Floor Function x - x % 1 gives -3 for -3.1234, surely, when the expected answer is -4 |

Sum of primes between given range I like how short this is, but I wonder how inefficient it would be when calculating up to 10^8! |

99 Bottles Of Beer @Daniel Yes, and it implies that he thinks everything in his code is necessary. If meant as a joke, it shouldn't be voted up this much. It's not short, creative, efficient, or even slightly clever. |
