Question

In Java you can get an element from an array directly from the method call, like this:

System.out.println(PrintArrayOfStrings()[0]);

Is there any similar way to do this in PHP?

echo PrintArrayOfStrings()[0]; // Does not work!

Or do I always have to use a variable that first gets the array and then I use that variable to get the element?

$array = PrintArrayOfStrings();
echo $array[0]; // Works!

Answer 1

echo PrintArrayOfStrings()[0]; 

is not possible/supported in PHP.

You can do it as you wrote:

$array = PrintArrayOfStrings();
echo $array[0];

or do it like this, if you want to have it on one line:

function get($array, $key){
    return $array[$key];
}

so then, you can use:

echo get(PrintArrayOfStrings(), 0);
