tweaking short circuit for logical operators

altexis

I know that the PHP logical operators work in short circuit
like in C++

My question is... is there any evnironment option allowing you to play with this feature???

Actually ive never thought of doing something like that. I dont actually think its possible though. But you could have a try i guess. It wouldnt hurt

I'd be very startled if there were such a setting.

But what do you mean "play with it"? Precedence can be overriden by (), and short-circuiting can also be eliminated by rewriting the test.

well... I come from the Delphi world.. in Delphi you can do
many such changes... but I am still fresh in web programming
and PHP as well.

I made some functions that are based in short-circuit
I just wanted to know if there is any chance an administrator
accidentally change a setting and throw all my scripts to the
garbage. Didn't think this question would surprise you so much

Many thanks though 🙂)

Well i am still. Now As PHP is Server Side i do not think it is possible. Now thinking about this more. As Delphi is a Compiled Language meaning its (C++ C# etc) its possible for them. But i dont think you could do it in PHP. But have a go look through some functions and maybe surpise us

Well, I program in C and C++, too, but I've never heard of being able to configure the short circuit feature. In fact, it says in the ISO 14882 standard for C++, page 88, that "the second operand [of &&] is not evaluated if the first operand if false." Same thing, but with boolean reversed, with the || operator.

I'm just curious, what kind of changes does Delphi allow?

I don't think I can impress much a C++ programmer...
Anyhow... Delphi has many (if not all) of the known
compiler options in the C++ world... such as Range checking, overflow checking, I/O checing... control for the size of the stack
the exe version information...

apart from the short-circuit option.. if there is something that might impress you is the "Pentium-safe FDIV" option - a workaround the bug of the very first Pentiums

then in code you are also able to do some low-level adjustments like the alignment of the function parameters in assembly level

I work with Pascal and Delphi all my life... its very sad that this language doesn't get the recognition it deserves

Anyway... lets PHP 🙂
