Above mention is my encoded value.

When iam trying to decode it iam getting the output in this format
a:6:{i:0;s:4:"2067";i:1;s:4:"2068";i:2;s:4:"2069";i:3;s:4:"2070";i:4;s:4:"2071";i:5;s:4:"2072";}

Now how to convert into
["2067","2068","2069","2070","2071","2072"] OR (2067,2068,2069,2070,2071,2072)
