Check that the values of an array are all the same PHP?

I would like to check that all values in my array are equal and I did so :

$minha_lista = array('a','a','a');

if(!empty($minha_lista)) {
    if(count(array_unique($minha_lista))===1){
             return true;
        } else { return false; }
    }

Unfortunately I can’t get the desired result.

There is another way to proceed ?

    But apparently if code is right, what’s wrong or what he doesn’t do?

  • your code is correct, you don’t need anything! only if you have something you’re not reporting in your question ... !!!

  • @André-pka Is there any other problem that is occurring? Because as the friend above said... Your code is correct.

You can do it with a loop, like this:

$arr = ['aaa', 'aaa', 'aaa'];
$status = true;

foreach($arr as $value) {
    if($arr[0] != $value) {
         $status = false;
         break;
    }
}

The variable $status begins as true and whether during the loop with the array is found some different value, it changes to false

There are some ways to do this check, for example:

if(count(array_unique($minha_lista))){
    //...
}

or even:

if($minha_lista === array_fill(0,count($minha_lista),$minha_lista[0])){
    //...
}

Here the documentation of the functions: array_unique, array_fill

Your code is correct. I left it more "explicit", take a look:

$check_array = ('a', 'a', 'a');

$result_array = array_unique($check_array);

if (count($result_array) == 1)
   echo "Valores iguais...";
else
   echo "Valores diferentes...";
