逻辑运算符，||还是OR? [英] Logical Operators, || or OR?

问题描述

我记得有一阵子关于逻辑运算符的内容，在OR的情况下，使用||比or更好(反之亦然).

I remember reading a while back in regards to logical operators that in the case of OR, using || was better than or (or vice versa).

当我回到项目中时，我只需要在项目中使用它，但是我不记得建议使用哪个运算符，甚至是真的.

I just had to use this in my project when it came back to me, but I can't remember which operator was recommended or if it was even true.

哪个更好，为什么?

推荐答案

没有更好"的选择，但更常见的是||.它们具有不同的 优先级 和||会像人们通常期望的那样工作.

There is no "better" but the more common one is ||. They have different precedence and || would work like one would expect normally.

另请参见: 逻辑运算符 (以下示例是从此处获取的):

// The result of the expression (false || true) is assigned to $e
// Acts like: ($e = (false || true))
$e = false || true;

// The constant false is assigned to $f and then true is ignored
// Acts like: (($f = false) or true)
$f = false or true;
