推荐答案

您也许可以使用 usort（ ）系列函数进行排序，要么在 STR 或 POS 。你必须定义你自己的比较函数。

You could probably use the usort() family of functions to sort it either on str or pos. You have to define your own comparison function for that.

伪PHP例如：

function compareItems($a, $b)
{
    if ( $a->pos < $b->pos ) return -1;
    if ( $a->pos > $b->pos ) return 1;
    return 0; // equality
}

uasort($yourArray, "compareItems");

根据您的需求， 可能更适合其他的比较功能。

Depending on your needs, other comparison functions might be more appropriate.
