How to remove duplicate values from a multi-dimensional array in PHP

I have an array like this:
Array
(
[0] => Array
(
[0] => Array
(
[Foo] => FooBar
)
)
[1] => Array
(
[0] => Array
(
[Foo] => BarFoo
)
)
[2] => Array
(
[0] => Array
(
[Foo] => FooFoo
)
)
[3] => Array
(
[0] => Array
(
[Foo] => FooFoo
)
)
)
I basically want to be able to look at [2] and [3] and be able to merge those two together since their values are the same. Basically I just don't want to double count. Is there a simple way of doing this while looping through?
You can try this
$unique_array = array_map("unserialize",
array_unique(array_map("serialize", $your_array)));

This should work for you:
Just loop through your array with array_map() and check if it is an array or not. If yes just return the unique array with array_unique(), else just return the value.
<?php
$unique = array_map(function($v){
if(is_array($v))
return array_unique($v);
return $v;
}, $array);
print_r($unique);
?>

I need output:

[1] => 62.173.145.00:17211
[2] => 61.10.231.00:52151
[3] => 66.171.81.00:41787

Take a look at array_merge(); http://php.net/manual/en/function.array-merge.php
$newArray = array_merge($a,$b);
Use the array_merge function described here.

How to achieve this in php???? Thanks in advance
Extract only the values to a new array and the keys will be indexed from 0:
$array = array_values($array);
The array_values() function returns only values from array.
Thus, resetting all the array keys to numeric starting from 0, 1, 2, ...
You can do it using
$array = array_values($array);
http://php.net/manual/en/function.array-values.php
you can use the "array_values" Function for that.
Please refer this link http://www.php.net/manual/en/language.types.array.php
