Arguments

• type - One of INPUT_GET, INPUT_POST, INPUT_COOKIE, INPUT_SERVER, INPUT_ENV, INPUT_SESSION (not implemented yet), or INPUT_REQUEST (not implemented yet).
• definition - An array defining the arguments. A valid key is a string containing a variable name and a valid value is either a filter type, or an array optionally specifying the filter, flags and options. If the value is an array, valid keys are filterwhich specifies the filter type, flagswhich specifies any flags that apply to the filter, and optionswhich specifies any options that apply to the filter. See the example below for a better understanding. This parameter can be also an integer holding a filter constant. Then all values in the input array are filtered by this filter.
