>!= PHP运算符,如何写不等于或大于？

Question

如何在PHP中编写不大于或等于？

是>!=吗？

Answer 1

不not greater than or equal to x一样less than x吗？

Answer 2

有趣哦.按复杂程度递增:

1. <
2. (a - b> 0)
3. !(a> = b)
4. !(a - b <= 0)
5. !((a> b)||(a == b))
6. !(a - b <0)&&!(a - b == 0)
7. !((a - b <0)||(a - b == 0))&&!(!(a <b))
8. !(a - b <((a*(1/a)-1)*(b*(1/b)-1)))&&!(a - b ==(a*(1/a)-1) )*(b*(1/b)-1)))

就个人而言,我会为那些真烦我的人保留#8.;)

Answer 3

写这个的最好方法是

$x = 4;
$y = 6;

if($x < $y) echo "True";

// True

$x = 4;
$y = 6;

if(!($x >= $y)) echo "True";

// True

Answer 4

"不大于或等于"等于你写的"严格小于" <.

如果你真的想说"不大于或等于"你可以写!(a >= b).

Answer 5

<

(小于或等于不大于)

Answer 6

从技术上讲,你提出了两个不同的问题 - 如何写A not greater than B or A equal to B和A not equal to B or A greater than B.

声明A not greater than B or A equal to B暗示:

!(A > B) || A == B

这是一个重言式:

A <= B

并A not equal to B or A greater than B暗示:

A != B || A > B

这是一个重言式:

A >= B

其他答案A < B是声明的代表A not greater than nor A equal to B.
