Push only unique values into an array while looping

array-push, arrays, php, unique

Solution

You check if it's there, using `in_array`, before pushing.

foreach($something as $value){
    if(!in_array($value, $liste, true)){
        array_push($liste, $value);
    }
}

The `,true` enables "strict checking". This compares elements using `===` instead of `==`.

Problem

I am using the following loop to add items to an an array. I would like to know if it is somehow possible to not add `$value` to the `$liste` array if the value is already in the array? ``` $liste = array(); foreach($something as $value){ array_push($liste, $value); } ```
