PHP 从多维数组中删除重复值 [英] PHP remove duplicate values from multidimensional array

问题描述

我们可以使用array_unique()从php中的单个多维数组中删除重复条目.是否可以与多维数组一起使用?它不适合我！

We can use array_unique() for remove duplicate entry from a single multidimensional array in php.Is it possible to use with multidimensional array? It is not working for me!

这是数组的样子

Array (
    [0] => Array ( [0] => 1001 [1] => john [2] => example )
    [1] => Array ( [0] => 1002 [1] => test [2] => dreamz )
    [2] => Array ( [0] => 1001 [1] => john [2] => example )
    [3] => Array ( [0] => 1001 [1] => example [2] => john )
    [4] => Array ( [0] => 1001 [1] => john [2] => example )
)

任何人都可以帮我...
