isSane()

static Auth_OpenID_TrustRoot::isSane (   $trust_root )

static

Is this trust root sane?

A trust root is sane if it is syntactically valid and it has a reasonable domain name. Specifically, the domain name must be more than one level below a standard TLD or more than two levels below a two-letter tld.

For example, '*.com' is not a sane trust root, but '*.foo.com' is. '*.co.uk' is not sane, but '*.bbc.co.uk' is.

This check is not always correct, but it attempts to err on the side of marking sane trust roots insane instead of marking insane trust roots sane. For example, 'kink.fm' is marked as insane even though it "should" (for some meaning of should) be marked sane.

This function should be used when creating OpenID servers to alert the users of the server when a consumer attempts to get the user to accept a suspicious trust root.

Parameters

string

$trust_root

The trust root to check

Returns

bool $sanity Whether the trust root looks OK

match()

static Auth_OpenID_TrustRoot::match (   $trust_root,   $url  )

static

Does this URL match the given trust root?

Return whether the URL falls under the given trust root. This does not check whether the trust root is sane. If the URL or trust root do not parse, this function will return false.

Parameters

string	$trust_root	The trust root to match against
string	$url	The URL to check

Returns

bool $matches Whether the URL matches against the trust root
