Need help for syntax

I'm looking for the kind to access at the value of an array directly from the object's method.

For example :

With this syntax, no problem :

$myArray = $myObject->getArray();

print_r($myArray[0])

But to reduce the number of line in source code, how to get the element directly with the method ?

I do that, but it's not correct :

$myArray = $myObject->getArray()[0];

The following is only available for PHP 5.4 and supposedly higher.

$myArray = $myObject->getArray()[0];

Unfortunately there is no quicker way below PHP 5.4.

See @deceze's answer for a good alternative.

Although it is possible to achieve this in PHP 5.4 with the syntax you've demonstrated, I have to ask, why would you want that? There are ways of doing it in 5.3 in a one-liner, but I don't see the need to do this. The number of lines is surely less interesting than the readability of the code?

For PHP 5.3-:

$myArray = current($myObject->getArray());

or

list($myArray) = $myObject->getArray();

IT IS IMPOSSIBRRUUU.

Serious answer: sadly it is not possible. You can write a very ugly wrapper like this:

function getValue($arr, $index)
{
    return $arr[$index];
}

$myArray = getValue($myObject->getArray(), 0);

But that makes less readable code.

If you are on php 5.4 (which support array dereferencing) you can do the second option:

$myArray = $myObject->getArray()[0];

If you are on PHP < 5.4 you can "fix" it in the class (of which the object is a instance):

class Foo
{
    public function getArray()
    {
        return $this->theArray;
    }

    public function getFirstItem()
    {  
         return $this->theArray[0];
    }
}

$myObject = new Foo();
print_r($myObject->getFirstItem());
