Question

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];

Answer 1

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());
