php - What is this encoding called? -


i see in wordpress in database , see similar in cookie. kind of parser parses this:

a:4:{s:14:"clientsorderby";s:9:"firstname";s:12:"clientsorder";s:4:"desc";s:13:"ordersorderby";s:2:"id";s:11:"ordersorder";s:4:"desc";}

i it, a=array:x=number of children s=string:x=number of characters.

is there parser built php kind of thing? why use method?

it's php's built-in serialize(), can "decoded" unserialize()

here example:

$serialized = 'a:4:{s:14:"clientsorderby";s:9:"firstname";s:12:"clientsorder";s:4:"desc";s:13:"ordersorderby";s:2:"id";s:11:"ordersorder";s:4:"desc";}'; $unserialized = unserialize( $serialized);  var_dump( $unserialized);

output:

array(4) {   ["clientsorderby"]=>   string(9) "firstname"   ["clientsorder"]=>   string(4) "desc"   ["ordersorderby"]=>   string(2) "id"   ["ordersorder"]=>   string(4) "desc" }
