Bookmark or Share- Does PHP have short-circuit evaluation? - Stack OverflowYes, it's short-circuit. The PHP interpreter does "lazy" evaluation of boolean operators, meaning it will do the minimum number of comparisons possible to evaluate conditions. If you want to verify that, try this:
- What is short circuiting and how is it used when programming in Java ...Short-circuit evaluation means that when evaluating boolean expressions (logical AND and OR) you can stop as soon as you find the first condition which satisfies or negates the expression. For example, suppose you were evaluating a logical OR with several sub-expressions, each of which is very costly to evaluate:
- Does Python support short-circuiting? - Stack OverflowShort-circuiting behavior in function: any(), all(): Python's any() and all() functions also support short-circuiting. As shown in the docs; they evaluate each element of a sequence in-order, until finding a result that allows an early exit in the evaluation.
- What exactly happens at short circuit? - Electrical Engineering Stack ...A short circuit between power supply leads will cause a large current to flow. The current will be limited only by the power source's internal resistance, and the resistance of the wires carrying the short-circuit current. If the wires, printed circuit tracks, or other components carry excessive current, they may overheat, melt insulation, burn ...
- sql - Does Oracle use short-circuit evaluation? - Stack OverflowIt depends. . In general, Oracle does not guarantee that a SQL statement will use short-circuit evaluation (though PL/SQL is guaranteed to perform short-circuit evaluation). The Oracle optimizer is free to evaluate the predicates in whatever order it expects to be most efficient.
