expectCT

Description

void expectCT (
    [ ?int | string $maxAge = 31536000 
    [, ?mixed $enforce = true 
    [, ?string $reportUri = null ] ] ] 
)

Used to add and configure the Expect-CT header. Expect-CT makes sure that a user's browser will fill the role of ensuring that future requests, within $maxAge seconds will have certificate transparancy.

If set to enforcement mode, the browser will fail the TLS connection if the certificate transparency requirement is not met

Parameters

maxAge

The length, in seconds either as a string, or an integer – specify the length that a user's browser should remember that the application should be delivered with a certificate transparency expectation.

enforce

Loosely casted as a boolean, whether to enforce (by failing the TLS connection) that certificate transparency is enabled for the next $maxAge seconds, or whether to only report to the console, and to $reportUri if an address is defined.

reportUri

A reporting address to send violation reports to.

Passing null indicates that a reporting address should not be modified on this call (e.g. can be used to prevent overwriting a previous setting).
