Detailed Description

PathRouter class.

This class can take patterns such as /wiki/$1 and use them to parse query parameters out of REQUEST_URI paths.

$router->add( "/wiki/$1" );

• Matches /wiki/Foo style urls and extracts the title $router->add( [ 'edit' => "/edit/$key" ], [ 'action' => '$key' ] );
• Matches /edit/Foo style urls and sets action=edit $router->add( '/$2/$1', [ 'variant' => '$2' ], [ '$2' => [ 'zh-hant', 'zh-hans' ] ] );
• Matches /zh-hant/Foo or /zh-hans/Foo $router->addStrict( "/foo/Bar", [ 'title' => 'Baz' ] );
• Matches /foo/Bar explicitly and uses "Baz" as the title $router->add( '/help/$1', [ 'title' => 'Help:$1' ] );
• Matches /help/Foo with "Help:Foo" as the title $router->add( '/$1', [ 'foo' => [ 'value' => 'bar$2' ] ] );
• Matches /Foo and sets 'foo' to 'bar$2' without $2 being replaced $router->add( '/$1', [ 'data:foo' => 'bar' ], [ 'callback' => 'functionname' ] );
• Matches /Foo, adds the key 'foo' with the value 'bar' to the data array and calls functionname( &$matches, $data );

Path patterns:

• Paths may contain $# patterns such as $1, $2, etc...
• $1 will match 0 or more while the rest will match 1 or more
• Unless you use addStrict "/wiki" and "/wiki/" will be expanded to "/wiki/$1"

Params:

• In a pattern $1, $2, etc... will be replaced with the relevant contents
• If you used a keyed array as a path pattern, $key will be replaced with the relevant contents
• The default behavior is equivalent to ‘array( 'title’ => '$1' ), if you don't want the title parameter you can explicitly usearray( 'title' => false )
• You can specify a value that won't have replacements in it using'foo' => [ 'value' => 'bar' ];`

Options:

• The option keys $1, $2, etc... can be specified to restrict the possible values of that variable. A string can be used for a single value, or an array for multiple.
• When the option key 'strict' is set (Using addStrict is simpler than doing this directly) the path won't have $1 implicitly added to it.
• The option key 'callback' can specify a callback that will be run when a path is matched. The callback will have the arguments ( &$matches, $data ) and the matches array can be modified.

Member Function Documentation

add()

PathRouter::add	(		$path,
			$params = [],
			$options = [] )

Add a new path pattern to the path router.

Parameters

string | array	$path	The path pattern to add
array	$params	The params for this path pattern
array	$options	The options for this path pattern

addStrict()

PathRouter::addStrict	(		$path,
			$params = [],
			$options = [] )

Add a new path pattern to the path router with the strict option on.

self::add

Parameters

string | array	$path
array	$params
array	$options

doAdd()

PathRouter::doAdd ( $path, $params, $options, $key = null )

protected

Protected helper to do the actual bulk work of adding a single pattern.

This is in a separate method so that add() can handle the difference between a single string $path and an array() $path that contains multiple path patterns each with an associated $key to pass on.

Parameters

string	$path
array	$params
array	$options
null | string	$key

expandParamValue()

static PathRouter::expandParamValue ( $pathMatches, $key, $value )

staticprotected

Replace $key etc.

in param values with the matched strings from the path.

Parameters

array	$pathMatches	The match results from the path
string | null	$key	The key of the matching pattern
string	$value	The param value to be expanded

Returns

string|false
