在 PHP 中使用 array_search 使对象可搜索
我想在 PHP 中创建一个类，以便可以使用 PHP 本机方法 array_search 进行搜索。目前，我的类实现了 IteratorAggregate 和 Countable，这允许我对其执行 foreach 操作。
还有几个其他 SPL 接口（SeekableIterator、ArrayAccess 等）似乎可能合适，但我想知道是否有人已经这样做了，以及哪个接口适合我想做的事情。
谢谢
I would like to make a class in PHP such as it would be searchable with PHP native method array_search. Currently my class implements IteratorAggregate and Countable, which allows me to do foreach on it.
There is a couple of other SPL interfaces (SeekableIterator, ArrayAccess, etc...) which seems to maybe fit, but I would like to know if someone has already done this and which interface is suitable for what I want to do.
Thank you

查看 FilterIterator。您实现继承自它的自己的类，然后在类中的
accept方法实现中进行比较。Check out FilterIterator. You implement your own class inheriting from it then do a compare in the
acceptmethod implementation in your class.如果可能的话，让您的类扩展
ArrayObject。如果不可能，请尝试基于 本手册了解您的对象真正需要使用哪个接口。Make your class extend
ArrayObject, if possible. If that's not possible, try implementing each of the interfaces that ArrayObject implements, one-by-one based on this manual to see which interface you really need to use for your object.
