使用'=='和'strcmp()'进行字符串比较 [英] String comparison using '==' vs. 'strcmp()'

问题描述

似乎PHP的===运算符区分大小写.那么有没有理由使用strcmp()?

It seems that PHP's === operator is case sensitive. So is there a reason to use strcmp()?

执行以下操作是否安全?

Is it safe to do something like the following?

if ($password === $password2) { ... }

推荐答案

使用它的原因是因为 strcmp

The reason to use it is because strcmp

返回<如果str1小于str2，则为0；否则，为0.如果str1大于str2，则> 0；如果相等，则为0.

returns < 0 if str1 is less than str2; > 0 if str1 is greater than str2, and 0 if they are equal.

===仅返回true或false，它不会告诉您哪个是更大"的字符串.

=== only returns true or false, it doesn't tell you which is the "greater" string.
