How can PHP developers ensure they are adding new elements to an array instead of overwriting it in a loop?

When adding new elements to an array in a loop, PHP developers can ensure they are not overwriting the existing array by using the array_push() function. This function appends one or more elements to the end of an array without overwriting the existing elements. 

$myArray = array();

for($i = 0; $i < 5; $i++){
    array_push($myArray, $i);
}

print_r($myArray);
