数字排序数组

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？

Array ( [0] => Array ( [name] => bit.ly/2oUTzf [count] => 1 ) [1] => Array ( [name] => tiny.cc/wyNbi [count] => 1 ) [2] => Array ( [name] => ow.ly/Almo [count] => 1 ) [3] => Array ( [name] => bit.ly/7bQ8sY [count] => 1 ) [4] => Array ( [name] => kissa.be/w4V- [count] => 5 ) [5] => Array ( [name] => ow.ly/xzwI [count] => 1 ) [6] => Array ( [name] => twa.lk/L6FZX [count] => 1 ) [7] => Array ( [name] => tinyurl/Alyssa10 [count] => 1 ) [8] => Array ( [name] => www.hiderefer/0cz7kNgA.htm [count] => 1 ) [9] => Array ( [name] => tinyurl/Joanie515 [count] => 1 ) [10] => Array ( [name] => ow.ly/uJvB [count] => 1 ) [11] => Array ( [name] => tinyurl/ [count] => 1 ) [12] => Array ( [name] => www.hiderefer/wJBUhh3G.htm [count] => 1 ) [13] => Array ( [name] => short.to/xcxc [count] => 1 ) [14] => Array ( [name] => bit.ly/t79FA [count] => 2 ) [15] => Array ( [name] => tinyurl/yzy33yl [count] => 1 ) [16] => Array ( [name] => p.gs/zksz6 [count] => 1 ) [17] => Array ( [name] => bit.ly/7E1cc8 [count] => 1 ) [18] => Array ( [name] => bit.ly/6hbugu [count] => 1 ) [19] => Array ( [name] => tii.libsyn/index.php [count] => 6 ) [20] => Array ( [name] => tinyurl/nlzzwq [count] => 1 ) [21] => Array ( [name] => bit.ly/7gAdXi [count] => 1 ) [22] => Array ( [name] => localtweeps [count] => 1 ) [23] => Array ( [name] => localtweeps.

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; }
