Oh, that handy acronym LAMP
Linux, Apache, MySQL, PHP! The darlings of the Web!
The argument over the letter P should have been easy – it was perl, but by the time we needed the word “LAMP” it had become PHP, simply by sheer weight of numbers (and not by quality). These days it's more likely to be Python, if you want a robust platform. Or Ruby!
Next to fall was the A – Apache is heavyweight, compared to lighttpd and now nginx. The language-specific apache modules are catered for by back-end application-dedicated HTTP servers like mongrel and my favourite workhorse, tracd.
And now the M, MySQL, seems to have shot itself in the foot and lost open-source credibility, confirming the utility of SQLite for small projects and PostgreSQL for big ones.
At least we can rely on the L for a bit longer … L(LN)(SP)(PR) ⇒ LNSPR ? Linspire? Nooooooooo …..
