Array (
    [0] => stdClass Object (
            [id] => 1
            [name] => Title One
        )    
    [1] => stdClass Object (
            [id] => 2
            [name] => Title Two
        )

    [2] => stdClass Object (
            [id] => 7
            [name] => Title Seven
        )
)

获得ID数组的最佳方法(即最快)是什么？即数组(1,2,7)我可以手动循环,但我觉得必须有一个更好的方法.

刚刚看到了this in the similar questions,但是对于接受的答案是否真的是最好的方法,加上它是从2年前就有一点争论.我在PHP 5.3.
