Bug description: Original Array modified after copy
Description:
------------
First problem: If I Create an array setting an element to a string and
another element as a reference to the first, then copy the array into an
other variable, if i modify the second variable also the original array is
modified.
Second problem:
why the second code line ($a[0]="foo";) produces
[0]=>
&string(3) "foo"
instead of
[0]=>
string(3) "foo"
Thanks
Andrea Busia
Reproduce code:
---------------
<?
$a=array();
$a[0]="foo";
$a[1] =& $a[0];
var_dump($a);
$b=$a;
$b[0]="bar";
var_dump($a);
?>
Expected result:
----------------
array(2) {
[0]=>
string(3) "foo"
[1]=>
&string(3) "foo"
}
array(2) {
[0]=>
string(3) "foo"
[1]=>
&string(3) "foo"
}
Actual result:
--------------
array(2) {
[0]=>
&string(3) "foo"
[1]=>
&string(3) "foo"
}
array(2) {
[0]=>
&string(3) "bar"
[1]=>
&string(3) "bar"
}
