function call by getting the name of function from URL

[eluser]Phil Sturgeon[/eluser]
Three ways to call a function from a variable name in PHP.

Option #1:

Code:

$this->{$function_name[1]}();

Option #2:

Code:

call_user_func(array($this, $function_name[1]), $param1, $param2, $param3);

Option #3:
$params = array( $param1, $param2, $param3 );

Code:

call_user_func_array(array($this, $function_name[1]), $params );
