static public array splitUri(string $uri, bool $createNamespace = false)

Try and breakup a URI into a prefix and local part

If $createNamespace is true, and the URI isn't part of an existing namespace, then EasyRdf will attempt to create a new namespace and return the name of the new prefix (for example 'ns0', 'term').

If it isn't possible to split the URI, then null will be returned.

Parameters

string $uri The full URI (eg 'http://xmlns.com/foaf/0.1/name')
bool $createNamespace If true, a new namespace will be created

Return Value

array The split URI (eg 'foaf', 'name') or null

at line 358
static public string prefixOfUri(string $uri)

Return the prefix namespace that a URI belongs to.

Parameters

string $uri A full URI (eg 'http://xmlns.com/foaf/0.1/name')

Return Value

string The prefix namespace that it is a part of(eg 'foaf')

at line 378
static public string shorten(string $uri, bool $createNamespace = false)

Shorten a URI by substituting in the namespace prefix.

If $createNamespace is true, and the URI isn't part of an existing namespace, then EasyRdf will attempt to create a new namespace and use that namespace to shorten the URI (for example ns0:term).

If it isn't possible to shorten the URI, then null will be returned.

Parameters

string $uri The full URI (eg 'http://xmlns.com/foaf/0.1/name')
bool $createNamespace If true, a new namespace will be created

Return Value

string The shortened URI (eg 'foaf:name') or null

at line 394
static public string expand(string $shortUri)

Expand a shortened URI (qname) back into a full URI.

If it isn't possible to expand the qname, for example if the namespace isn't registered, then the original string will be returned.

Parameters

string $shortUri The short URI (eg 'foaf:name')

Return Value

string The full URI (eg 'http://xmlns.com/foaf/0.1/name')
