How to extract key value pairs from a specific format string using regular expression?

I have a string with a specific format 

'a:3:{s:8:"postid";s:1:"100";s:6:"commentid";s:1:"200";s:6:"website";s:24:"http://www.example.com";}';

Please note that above string is not JSON, serialized object or any other data format.

May requirement is to extract the each value in the double quotes and map with the next item in the double quotes.

My required output is an array map

[postid:100, commentid:200, website:"http://www.example.com"]

Is this possible to achieve with regular expression? provided keys postid, commentid and website will be always present in the input string.

This simple one should suit your needs:

"([^"]+)"[^"]+"([^"]+)"

As you can see, the first group will contain the key and the second one the value.

"(.*?)";[a-zA-Z]*:\d*:\"(\S+?)"

Try this.This will give all groups.See demo.
