`protected static`	# `initializeGlobals( )` Todo keep a documentation record of globals
`public static boolean`	# `exists( string $key )` Check if global variable exists Check if global variable exists Parameters `$key` Returns boolean Throws Exception
`public static mixed\|callable\|array`	# `get( string $key = null, $operators = null )` Get global key's value. An expression to access array elements or a function can be given. Get global key's value. An expression to access array elements or a function can be given. Parameters `$key` Expression key, can have parenthesis or square brackets operator. `$operators` Returns mixed\|callable\|array If you access a function without the parenthesis operator or an array without square brackets operator then this method will return the callable or the whole array respectively. Throws Exception When expression key is invalid. `Phramework\Exceptions\NotFoundException` When key is not found. Example Globals::get('myVarible'); Globals::get('rand-boolean()'); Globals::get('rand-integer(10)'); //A random integer from 0 to 10 Globals::get('myArray[1]'); //Get second array element
`public static mixed[]`	# `handleFunctionVariable( string[] $parameters )` Parameters `$parameters` Returns mixed[]
`public static mixed`	# `handleArrayVariable( string $value )` Parameters `$value` Returns mixed Throws `Phramework\Testphase\Exceptions\UnsetGlobalException` Exception
`public static`	# `set( string $key, mixed $value )` Will overwrite value with same key Will overwrite value with same key Parameters `$key` Key `$value` Throws Exception When key is invalid, see Expression::PATTERN_KEY Example Globals::set('myVariable', 5); Globals::set( 'dots', function ($length = 4) { return str_repeat('.', $length); } ); Globals::get('dots()'); //Will return a string of 4 dots Globals::get('dots(10)'); //Will return a string of 10 dots
`public static string`	# `toString( )` Return keys and values of global variables as string Return keys and values of global variables as string Returns string
