无法在PHP in_array中搜索数组是否存在多个指针 [英] Can't search an array in PHP in_array for the presence of multiple needles

问题描述

给PHP in_array 一个我要搜索的值数组时，它不起作用.尽管文档指定您可以使用 mixed 针.

When giving PHP in_array an array of values I want to search for, it does not work. Although the documentation specifies that you can give a mixed needle.

因此，基本上，我想测试是否存在多个术语作为数组的值-是否有理由不起作用，有人可以建议另一种方法吗?

So basically I want to test for the presence of multiple terms as the value of an array - is there a reason this is not working, and can anyone suggest another way of doing this?

推荐答案

mixed并不意味着一根以上的针，而是指类型.这是有关多种可能类型的文档讨论.

mixed doesn't mean more than one needle, it refers to types. It's documentation talk for more than one possible type.
