Perl is Lego, PHP is Playmobil
Quotes from different sources:
Perl is for creation, PHP is for play
When we just want to "play", scenarios/stories, we play with the Playmobil (or, rarely the Lego sets that are already/still built)
When we want to "create things", people, space ships, buildings, build scenarios, we use Lego.
PHP is limited
Playmobil is mostly modeling. While you can add items to it, they are all "Playmobilized" versions of actual items. The detail is incredible, but customization is limited, and you're limited in what you can create with it. You're limited to the set designer's imagination.
Lego is a building toy. While items may not look as finished, there's a larger ability to customise and "tweak" the sets to your liking. Plus, you can rebuild a set to whatever you want, add to sets to create your own items, and construct things that only exist in your imagination.
Apples and oranges?
BTW, to NA people the comparison between LEGO and playmobil may seem farfetched and irrelevant, because they are in essence totally different kind of toys. However, in Europe, they are marketed as direct competitors. The LEGO shelves are next to the Playmobil shelves, equal in size and competing for the attention (and wallets) of the same kids/parents, both with (mostly) themed sets. Any dutch toy store has three main walls with respectively LEGO, Playmobil and K'nex. A theme-triggered buyer has to choose beteen LEGO and Playmobil; a construction-triggered buyer has to choose between LEGO and K'nex.
Perhaps C is K'nex?
