What does a:1:{s:10:”subscriber”;b:1;} mean? (In roles / Capabilities)

  • Hi.

    Can someone explain to me what the different parts of the capability / role means? I’m guessing that S:10 means level 10 of that specific role? But what is a:1 and b:1 ?

    And can I add additional roles here? If yes, where?

    Nope. What you are looking at is a serialized string, which is a text representation of a value, usually an array or an object. The number is a kind of data validation. Its a count of the number of characters in the part of the value it refers to– in this case ‘subscriber’. See? Ten letters in ‘subscriber’. Unserialized it “looks” like this:

    array (
  'subscriber' => true,
)

    All it means it that this user has the ‘subscriber’ role.

    Lets see if I can get this right. ??

    a = array
    1 = with one element in the array
    { = start the bit referred to by a:1:
    array key is a…
    s = string
    10 = of ten characters
    subscriber = the ‘name’ of the key is ‘subscriber’
    array value is a…
    b = boolean
    1 = value set to true
    } = end the array referred to by a:1:
