如何根据重复的列值php删除关联数组中的行

Question

我有这个 Associate 数组。 Quick Track Club 出现两次 我想删除名称列中的任何重复项的整行。使用php

0 | Array
0 => 1
1 => Long Beach Sprinters
2 => LBS
3 => 1
4 => 0
5 => 0
6 => FALSE
7 => 0
1 | Array
0 => 2
1 => Quick Track Club
2 => QTC
3 => 1
4 => 0
5 => 0
6 => FALSE
7 => 0
2 | Array
0 => 3
1 => Mark Of a Champion
2 => MaC
3 => 2
4 => 0
5 => 0
6 => FALSE
7 => 0
3 | Array
0 => 4
1 => Unattached
2 => Unattached
3 => 2
4 => 0
5 => 0
6 => FALSE
7 => 0
4 | Array
0 => 5
1 => Quick Track Club
2 => QTC
3 => 2
4 => 0
5 => 0
6 => FALSE
7 => 0

如果没有第二次出现 Quick Track Club，它应该看起来像虱子。 array_unique 不起作用，因为整行不相同我正在从 csc 文件创建数组

0 | Array
0 => 1
1 => Long Beach Sprinters
2 => LBS
3 => 1
4 => 0
5 => 0
6 => FALSE
7 => 0
1 | Array
0 => 2
1 => Quick Track Club
2 => QTC
3 => 1
4 => 0
5 => 0
6 => FALSE
7 => 0
2 | Array
0 => 3
1 => Mark Of a Champion
2 => MaC
3 => 2
4 => 0
5 => 0
6 => FALSE
7 => 0
3 | Array
0 => 4
1 => Unattached
2 => Unattached
3 => 2
4 => 0
5 => 0
6 => FALSE
7 => 0

一种方法是记录使用过的名称并对其进行过滤。

$names = [];
$associates = array_filter($associates, function($a) { return (!in_array($a[1], $names) && $names[]=$a[1];)});
