easier way, assuming the <code>$str</code> is trustable data

I have this string: <code>test1__test2__test3__test4__test5__test6=value</code>

There could be any number of test-keys.

I want to write a function that can turn the string above into an array

<pre><code>$data[test1][test2][test3][test4][test5][test6] = "value";
</code></pre>

Is this possible?

我有这个字符串：test1__test2__test3__test4__test5__test6=value可以有任意数量的测试密钥。我想写一个可以把上面的字符串转换成数组的函数$data[test1][test2][test3][test4][test5][test6] = "value";这个是可能的吗？
