Bug description: Array does not serialize properly
Description:
------------
When certain strings are unserialized they do not reserialize properly.
Reproduce code:
---------------
<?php
$x = array();
$x[] = &$x;
var_dump($x);
$z = serialize($x);
echo $z . "\n";
var_dump(unserialize($z));
echo "\n\n\n";
$x = unserialize("a:1:{i:0;R:1;}");
var_dump($x);
$z = serialize($x);
echo $z . "\n\n";
var_dump(unserialize($z));
Expected result:
----------------
array(1) {
[0]=>
&array(1) {
[0]=>
&array(1) {
[0]=>
*RECURSION*
}
}
}
a:1:{i:0;a:1:{i:0;R:2;}}
array(1) {
[0]=>
&array(1) {
[0]=>
&array(1) {
[0]=>
*RECURSION*
}
}
}
array(1) {
[0]=>
&array(1) {
[0]=>
&array(1) {
[0]=>
*RECURSION*
}
}
}
a:1:{i:0;R:1;}
array(1) {
[0]=>
&array(1) {
[0]=>
&array(1) {
[0]=>
*RECURSION*
}
}
}
Actual result:
--------------
array(1) {
[0]=>
&array(1) {
[0]=>
&array(1) {
[0]=>
*RECURSION*
}
}
}
a:1:{i:0;a:1:{i:0;R:2;}}
array(1) {
[0]=>
&array(1) {
[0]=>
&array(1) {
[0]=>
*RECURSION*
}
}
}
array(1) {
[0]=>
array(1) {
[0]=>
array(1) {
[0]=>
*RECURSION*
}
}
}
a:1:{i:0;a:1:{i:0;a:1:{i:0;N;}}}
array(1) {
[0]=>
array(1) {
[0]=>
array(1) {
[0]=>
NULL
}
}
}
