哪个版本的php添加了匿名功能 [英] Which version of php added anonymous functions

问题描述

在手册中有create_function函数，您可以将结果从该函数传递给array_map，我认为这是拥有类似匿名函数和闭包之类的唯一方法，但是后来我发现我可以放功能类似于javascript

In manual there is create_function function and you can pass result from that function to array_map, I thought that that is the only way to have something like anonymous functions and closures, but then I found that I can just put function like in javascript

array_map(function($a) {
    return $a + 1;
}, array(1, 2, 3, 4, 5));

我可以在哪个版本的php中执行此操作?这总是在那里吗?

In which version of php I can do this? Was this always there?
