PHP short circuit lazy evaluation, where is it in the php.net manual?
Closest thing I can find to an 'official' mention of PHP's short-circuit implementation: php.net/manual/en/language.operators.log....
2 It's written inside the code snippet. First comment: // foo() will never get called as those operators are short-circuit – zneak Jul 10 '10 at 21:39 Thanks for the help! It's not stated loud and clear, but it's written there and also with clear examples.

This is not an uncommon feature of expression evaluation. The PHP manual page on logical operators makes a passing reference to it in one of the illustrative examples though. Short circuit evaluation is a commonly exploited idiom, and you can rely on its continued support in the language, otherwise vast amounts of code would break!
But I Googled the web and also Googled specifically both the php.net site and the stackoverflow.com site. I know PHP does short circuit lazy evaluation when using and, or, &&, || operators, but where is it stated loud and clear in the PHP manual? I found only Wikipedia as the only 'trusted' source that say PHP does lazy evaluation on these operators.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
