Message:

I´m trying to get this array

 [24]=>

  array(2) {

    [0]=>

    string(1) "21"

    [1]=>

    string(1) "22"

  }

So far I have this:

function Job($conn){

    $array = array();

    foreach(array_unique($_SESSION['ROLES']) as $value)

    {

        $sql="SELECT employee,task FROM table WHERE id={$value} AND employee=24";//echo($sql);

        $result = $conn->executeSQL($sql); 

        foreach($result as $value)

        {

            $array[$value['employee']][] = $value['task'];

                 

        }               

    }

      

 return $array;  

               

}

Which returns the tasks for two values I have store in $_SESSION['ROLES'] but if there are duplicates I need to remove them :

 [24]=>

  array(4) {

    [0]=>

    string(1) "21"

    [1]=>

    string(1) "22"

    [2]=>

    string(1) "21"

    [3]=>

    string(1) "22"

  }

My Answer:
To remove duplicates from an array in PHP, you can use the `array_unique()` function. Here's an example of how you can use it:

php
// Original array with duplicates
$array = [24, 24, 36, 48, 24, 36];

// Remove duplicates
$uniqueArray = array_unique($array);

// Print the unique array
print_r($uniqueArray);


This will output:


Array
(
[0] => 24
[2] => 36
[3] => 48
)


As you can see, the duplicates have been removed from the original array.
