数字排序数组 [英] Sorting arrays numerically
本文介绍了数字排序数组的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个需要排序的PHP数组。我在下面包括了示例数组。我需要将排名前10位的URLS及其透视数放入另一个数组中。我知道如果没有10个顶级匹配项，我可能会遇到问题...如果发生这种情况，则可以进行随机匹配。
I have a PHP array that I need to sort. I have included the example array below. I need to put the top 10 number of URLS plus their perspective counts in a different array. I know I could run into problem if there aren't 10 top matches ... if that happens then a random matching would be fine.
有什么建议吗？
我尝试过sort（myarray），但这只是对数组中的第一个对象进行排序，而我需要对第二个对象进行排序。
I have tried sort(myarray) but that just sorts the first object in the array I need it to sort the second.
有什么想法吗？

推荐答案
您需要编写自定义排序功能-像这样：
You need to write a custom sorting function - like this:
function MyCustomSort($a, $b)
{
if ($a->count == $b->count) {
return 0;
}
return ($a->count < $b->count) ? -1 : 1;
}
然后您将该函数传递给一个类-
Then you pass that function into a sort - like this:
usort($myArray, "MyCustomSort");
您还可以编写一个函数来帮助您按网站排序-
You could also write a function to help you sort by website - like this:
function MyCustomSort($a, $b)
{
if ($a->name == $b->name) {
return 0;
}
return ($a->name < $b->name) ? -1 : 1;
}
