答
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");
Depending on your needs, other comparison functions might be more appropriate.
