Bug description: Cannot unserialize() a string serialized with serialize()
Not sure if this is a bug but serialize() cannot work with arrays that
holds elements which points to the array itself
<?php
$b=array(1,2,4);
$b[]=&$b;
$str=serialize($b);
var_dump($b);
var_dump($str);
$c=unserialize($str);
var_dump($c);
?>
The ouput is:
array(4) {
[0]=>
int(1)
[1]=>
int(2)
[2]=>
int(4)
[3]=>
*RECURSION*
}
string(64)
"a:4:{i:0;i:1;i:1;i:2;i:2;i:4;i:3;a:4:{i:0;i:1;i:1;i:2;i:2;i:4;}}"
bool(false)
If
$b[]=&$b;
removed the output is:
array(3) {
[0]=>
int(1)
[1]=>
int(2)
[2]=>
int(4)
}
string(30) "a:3:{i:0;i:1;i:1;i:2;i:2;i:4;}"
array(3) {
[0]=>
int(1)
[1]=>
int(2)
[2]=>
int(4)
}
That's ok.
Serialize() have either to check against recursion or encode somehow the
recursion in the serialized(great BC impact).
