PHP remove duplicate values from multidimensional array
arrays, multidimensional-array, php
Solution
The user comments on the array_unique page do shed some light on this. You will most likely find some hidden gems in those comments - its a very handy documentation.
Just a quick browser through revealed the following to remove duplicates from a multi dimensional array:
<?php
function super_unique($array)
{
$result = array_map("unserialize", array_unique(array_map("serialize", $array)));
foreach ($result as $key => $value)
{
if ( is_array($value) )
{
$result[$key] = super_unique($value);
}
}
return $result;
}
?>
Problem
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! Here's what the array looks like ``` 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 ) ) ``` Anybody can please help me...
