Getting backreferences to all matches of a caturing group instead of the last

[448191]

I have this pattern (matching a PHP serialized string):

 

(\w:\d*?:"([a-zA-Z0-9_]*?)":\d*:){(?:((\w:\d*?:"##0[\w\*]*?##0([a-zA-Z0-9_]*?)";([a-z])):(.*?)*)}

 

 

Problem is I need to capture all occurrences (keys, datatypes and value) of the underlined groups. Right now every match overwrites the backreferences of the previous match, but wasn't there a way to avoid that? I'm having some sort of deja vu feeling about the thing.

 

Example string:

 

O:16:"DomainObjectStub":4:{s:21:"##0DomainObjectStub##0_id";i:1;s:14:"##0*##0_someString";s:9:"someValue";s:28:"##0DomainObjectStub##0_someFloat":0.1000000000000000055511151231257827021181583404541015625;s:12:"##0*##0_someBool";b:0;}

Wow 448191 (err.. nice screen name ).. Got to be honest, that sample string turns my head and stomach a little bit.

Could you provide the same sample string with the sections within it highlighted red that you wish the regex pattern to match / capture?

 

Would make it easier for the rest of us to see what it is exactly in the string you need, as opposed to trying to decypher your current regex pattern.

are you wanting to capture any of that other stuff, or just those 3 things?

Actually this is only a starting point. This won't work with nested compound types, so it would get (a lot) more complicated. Not to be rude, but you don't see what that says it won't help me to explain it to you.

Those three things and the second group (matching the first DomainObjectStub in the example). I should've removed the first group.

$string = 'O:16:"DomainObjectStub":4:{s:21:"##0DomainObjectStub##0_id";i:1;s:14:"##0*##0_someString";s:9:"someValue";s:28:"##0DomainObjectStub##0_someFloat":0.1000000000000000055511151231257827021181583404541015625;s:12:"##0*##0_someBool";b:0;}';
preg_match_all('/(?:.+?:.+?:"(\w+)":.+?:{)?(?:\w+:\w+:".*?(_\w+)";(.+?).+?);)/',$string,$matches);
echo "<pre>";
print_r($matches);
echo "</pre>";
