Use array_unique($array) function in order to remove duplicate value. It takes an input array and returns a new array without duplicate values.

What you want to achieve? Can you send me your code or script? I will do and let you know. – Darshan Jain Mar 21 '18 at 09:55
i think because i'am in a loop this is my code : `code` $cache = []; for($i=0;$i<=count(get_numerics($name));$i++){ $cc = get_numerics($name); $num = $cc[$i]; $cc = validatefunc($num); if (is_numeric($cc)) { if(trueresult($cc)) { if (!in_array($cc, $cache)){ $cache[] = $cc; } } } } – Zimo Mar 21 '18 at 10:06
@Zimo - Provide your array input and expected output so I can do as per your requirements. This code isn't be identify properly. – Darshan Jain Mar 21 '18 at 10:10

@Zimo please update your question with your code because we don't know what does your `get_numerics()`, `validatefunc()` and `trueresult()` functions. This answer is the correct one for the question you asked so far. – micster Mar 21 '18 at 10:15

You can use array_merge() first. Then on result do array_unique();

i try this code and not work : $arrmerg = array_merge($cache); $unique=array_unique($arrmerg); print_r($unique); – Zimo Mar 21 '18 at 09:58
post the code you're currently working with. Can't help with it not completely posted. – Karlo Kokkak Mar 21 '18 at 09:59
btw, array_merge uses two paramaters : array_merge($array1, $array2); – Karlo Kokkak Mar 21 '18 at 10:00
but i have only one array $data – Zimo Mar 21 '18 at 10:10

$input = array_map("unserialize", array_unique(array_map("serialize", $array)));
