Just as Kevin Stone said, you can either use one of these constructions: function func1() { global $myarray; array_push($myarray,1); } # _or_ function func2() { array_push($GLOBALS['myarray'],1); }
In fact, there is no performance decrease, because PHP will internally use the same mechanism to access the array - as it would if you were not in a function. Another way would be to pass the array as a reference: function func3(&$myarray) { array_push($myarray, 1); } but this might decrease performace (in compare to the other ways, you will not really notice it).
