ID: 20993
User updated by: henrik.gebauer@web.de
Reported By: henrik.gebauer@web.de
Status: Open
Bug Type: Variables related
Operating System: Windows 2002
PHP Version: 4.3.0RC3
New Comment:
I create an array an then a reference to an element of that array.
Then the array is passed to a function (by value!) which changes the
value of the element.
After that, the global array has also another value.
I would expect this behaviour if I passed the array by reference but I
do not.
<?php
$array = array(1);
$reference =& $array[0];
echo $array[0], '<br>';
theFunction($array);
echo $array[0], '<br>';
function theFunction($array) {
$array[0] = 2;
}
?>
