哪个版本的php添加了匿名函数

问题描述

在手册中有 create_function 函数，您可以将该函数的结果传递给 array_map，我认为这是拥有匿名函数和闭包之类的唯一方法，但后来我发现我可以像在javascript中一样放置函数

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?一直都这样吗?

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

在 PHP 中添加了闭包(匿名函数)5.3.0
