Question

以下是我的数组的部分内容

我尝试使用下面的功能对其进行排序，按页面升序排序然而，它似乎隆隆作响，页面没有处于增量状态。

我不确定我的排序比较器功能（cmp）

有什么问题

function cmp($a, $b) {
    return $a['page'] - $b['page'];
}


usort($chapter_result_array,"cmp");
$chapter_result_array = array_reverse($chapter_result_array);

Answer 1

我猜这些网页不是addChild(new devTextMC());值，而是更像“版本字符串”，因此您应该与版本比较进行比较：Compare two version strings in PHP

它将返回-1，0或1，如var instance:devTextMC = new devTextMC(); addChild(instance); instance.x = 100; instance.y = 50;意图使用。

PHP按升序数组值
