How to check if variable is equal to another variable in array [duplicate]

Question

Let's say if I have this variable $a = 'test';

Now let's say I created an array of multiple items like so:

$array['hello'] = 'yes';
$array['goodbye'] = 'no';
$array['afternoon'] = 'test';

Is it possible to check if any of the items in the array are the same, similar to isset(), then to get which item it is equal to it ($array['afternoon'])?

Seems like you're after array_search: stackoverflow.com/questions/6046908/php-index-of-item — Nick Parsons

You can check array has duplicated by this code: ` function array_has_dupes($array) { return count($array) !== count(array_unique($array)); }` — sameera lakshitha

Thank you that is actually what I was looking for Nick. I didn't know that the function existed. — Elijah Cruz

just use foreach()

foreach($array as $key => $val){
 if($key == $a){
  echo $val;
 }
}

Better way

use array_key_exists()

if(array_key_exists($a, $array)){
 echo $a;
}

Sorry I was in the middle of fixing it to how I need it, but I have updated it.

I updated my answer, and I didn't realize you were trying to check for duplicate value.
