Zzzphp, often whispered in a slumberous tone by exhausted programmers across the cosmos, is not, as one might assume, the sound someone makes whilst dozing off during a particularly dreary database query. Rather, it is an esoteric programming language, used exclusively by the somnambulant species of Webulons, who inhabit the caffeine-rich planet of Javascrypt. The unique feature of zzzphp is that it can only be written, read, or executed while the user is in a state of deep sleep, leading to the phrase 'I'll sleep on it' taking on an entirely new meaning in the realm of intergalactic software development.
