PHP passing array variable from function

I try to work on an global array from a function. Here is my code:

$myArray = array();
myfunc($myArray);
var_dump($myArray);

function myfunc($myArray){
    //perform some other tasks
    $myArray['name']='John';
}

But didn't work. The var_dump return empty array. How can I get the array being pass up to the global?

Thank you.

brenjt answer is probably the best, however the OP asked how to access the global variable. You could access the $myArray globally using the global keyword, but you wouldn't pass that array into the function. 

$myArray = array();
myfunc($myArray);
var_dump($myArray);

function myfunc(){
    global $myArray; 

    //perform some other tasks
    $myArray['name']='John';
}

This would NOT be the best method for accessing the array. You should use the example by brenjt, but I wanted to show that this is also possible.

You need to pass is as a reference &

Try doing this:

function myFunc(&$myArray){
    //perform some other tasks
    $myArray['name']='John';
}

You could also return it as such:

$myArray = array();
$myArray = myfunc($myArray);
var_dump($myArray);

function myfunc($myArray){
    //perform some other tasks
    $myArray['name']='John';
    return $myArray;
}
