getAttributeNamespace()

static SimpleSAML\Utils\Attributes::getAttributeNamespace (   $name,   $defaultns  )

static

Extract an attribute's namespace, or revert to default.

This function takes in a namespaced attribute name and splits it in a namespace/attribute name tuple. When no namespace is found in the attribute name, it will be namespaced with the default namespace. This default namespace can be overriden by supplying a second parameter to this function.

Parameters

string	$name	The namespaced attribute name.
string	$defaultns	The default namespace that should be used when no namespace is found.

Returns

array The attribute name, split to the namespace and the actual attribute name.

            $name = substr($name, $slash + 1);
        }
        return array(htmlspecialchars($defaultns), htmlspecialchars($name));
    }

getExpectedAttribute()

static SimpleSAML\Utils\Attributes::getExpectedAttribute (   $attributes,   $expected,   $allow_multiple = false  )

static

Look for an attribute in a normalized attributes array, failing if it's not there.

Parameters

array	$attributes	The normalized array containing attributes.
string	$expected	The name of the attribute we are looking for.
bool	$allow_multiple	Whether to allow multiple values in the attribute or not.

Returns

mixed The value of the attribute we are expecting. If the attribute has multiple values and $allow_multiple is set to true, the first value will be returned.

Exceptions

InvalidArgumentException If $attributes is not an array or $expected is not a string.

Exceptions

SimpleSAML_Error_Exception If the expected attribute was not found in the attributes array.

normalizeAttributesArray()

static SimpleSAML\Utils\Attributes::normalizeAttributesArray (   $attributes )

static

Validate and normalize an array with attributes.

This function takes in an associative array with attributes, and parses and validates this array. On success, it will return a normalized array, where each attribute name is an index to an array of one or more strings. On failure an exception will be thrown. This exception will contain an message describing what is wrong.

Parameters

array

$attributes

The array containing attributes that we should validate and normalize.

Returns

array The normalized attributes array.

Exceptions

InvalidArgumentException If input is not an array, array keys are not strings or attribute values are not strings.
