You guys should update this article and replace the “to be continued” bit at the bottom with a link to part 2 so I don’t have to go back to google to find it.

For a beginner (medium), this lazy php approach is a very good tip when writing code. Tnx !

[…] Tried to explain the basics a long time ago here—the important thing to take from that (compared to mod_perl / mod_python / mod_* or even “X” application server.) is the interpreter returning to a fresh state after every request (no globals hanging around or otherwise). PHP really is shared nothing. You want scaling? Try here. […]

[…] With PHP it’s very hard for a script to take down the runtime environment—the web server—I’d argue that you’d have to be deliberately trying to do so, perhaps filling up disk space or otherwise. Innocent mistakes, specific instances of runtime problems (e.g. script execution too long) and bugs remain local to specific requests and the PHP script handling them. On the next request, we begin again from scratch. […]

Nice tip. I like the use of the word ‘lazy’ rather than something along the lines of ‘optimisation’, quite apt for a person such as myself :)

“As a side note this tip would also be helpful in other forms of OO programming not just PHP”

Very true: there’s a number of pages on the C2 wiki about Laziness: http://c2.com/cgi/wiki?search=Lazy .

Think PHP’s case is a little special to the point where you need to use “eXtreme Laziness” because it dumps everything between requests - with compiled language that’s not the case and in most enviroments, memory tends to stay around for a little longer that 30 seconds.

So being lazy is a good thing? Great! :D

Really is true, though. I don't make those big scripts where you might have 101 functions, but it's never too early to start a good habit :)

Lol, "lazy" certainly attracted my attention ;) Also with PHP5 almost at RC quality, we shouldn't forget __autoload().

‘Unlike include(), require() will always read in the target file, even if the line it’s on never executes.’

That applies to PHP versions below 4.0.2.
