CLIRequest Class

If a request comes from a command line invocation, the request object is actually a CLIRequest. It behaves the same as a conventional request but adds some accessor methods for convenience.

Additional Accessors

getSegments()

Returns an array of the command line arguments deemed to be part of a path:

// command line: php index.php users 21 profile -foo bar
echo $request->getSegments();  // ['users', '21', 'profile']

getPath()

Returns the reconstructed path as a string:

// command line: php index.php users 21 profile -foo bar
echo $request->getPath();  // users/21/profile

getOptions()

Returns an array of the command line arguments deemed to be options:

// command line: php index.php users 21 profile -foo bar
echo $request->getOptions();  // ['foo' => 'bar']

getOption($which)

Returns the value of a specific command line argument deemed to be an option:

// command line: php index.php users 21 profile -foo bar
echo $request->getOption('foo');  // bar
echo $request->getOption('notthere'); // NULL

getOptionString()

Returns the reconstructed command line string for the options:

// command line: php index.php users 21 profile -foo bar
echo $request->getOptionPath();  // -foo bar
