PHP - function return an array after array_push [duplicate]

Question

Why is 'the array pushed element' not echoed?

function dofoo1() {  

    $array = array("1aaa", "2bbbb", "3cccc");  
    $count = '######';  
    $array1 = array_push($array, $count);  

    return $array1;  
}  

$foo1 = dofoo1();  
echo $foo1[3];  

Answer 1

No need to assign array_push to a variable.

function dofoo1() {

    $array = array("1aaa", "2bbbb", "3cccc");  
    $count = '######';  
    array_push($array, $count);  

    return $array;  
}  


$foo1 = dofoo1();  
echo $foo1[3];
