Does this recording format have a name?

Question

Text Processing Automation

Good day! There is such a data format (it is in the database for WP):
a:2:{i:0;s:4:"main";i:1;s:6:"active";}
Tell me, what is this record format? Thanks in advance for the replies!

Answer 1

Good.
serialized data.
In this case, it's an array of two elements: main and active.

array (
  0 => 'main',
  1 => 'active',
);
