Hi,
We noticed that current versions of PHP::Serialization return 0 instead
of undef for boolean data. In the following example:
#!/usr/bin/perl
use PHP::Serialization;
use Data::Dumper;
$s = 'a:4:{i:0;s:3:"ABC";i:1;s:3:"OPQ";i:2;s:3:"XYZ";i:3;b:0;}';
$u = PHP::Serialization::unserialize($s);
print(Dumper($u));
we got the following output:
$VAR1 = [
'ABC',
'OPQ',
'XYZ',
0
];
Isn't it supposed to be:
$VAR1 = [
'ABC',
'OPQ',
'XYZ',
undef
];
Looks like the following patch is needed:
