What is the issue with trying to retrieve the names of arrays passed as arguments to a function in PHP?

When arrays are passed as arguments to a function in PHP, the function only receives the values of the arrays, not the actual array variable names. Therefore, it is not possible to retrieve the names of the arrays directly within the function. One way to work around this limitation is to pass the array along with a string identifier that represents the array name. This way, the function can access the array values and the identifier to differentiate between multiple arrays passed as arguments. 

function retrieveArrayName($array, $arrayName) {
    echo "Array name: " . $arrayName . "\n";
    print_r($array);
}

$myArray = [1, 2, 3];
retrieveArrayName($myArray, "myArray");
