mixed filter_input_array ($type_of_data, $definition, $add_empty_parameter)Parameters:This function takes three parameters as above and described below:
- type_of_data:This is a required parameter. It contains the type of data input to be checked. Available options:
- INPUT_GET
- INPUT_POST
- INPUT_COOKIE
- INPUT_SERVER
- INPUT_ENV
- definition:this is an optional parameter. It defines an array of arguments or filter parameters. A valid array key as a variable name and a valid value as a filter name or identifier, or an array specifying the filter, flags, and parameters. This parameter can also be a single filter name / ID, like filter_input(), then all values in the input array are filtered by the specified filter.
- add_empty_parameter:this is an optional parameter. This is a boolean parameter. It adds missing keys as NULL to the return value when it is set to True. The default is True.
$filters = array ( "name" = > array ( "filter" = > FILTER_CALLBACK, " flags " = > FILTER_FORCE_ARRAY, "options" = > "ucwords"), "age" = > array ( "filter" = > FILTER_VALIDATE_INT, "options" = > array ( " min_range " = > 1, "max_range" = > 120 )), "email" = > FILTER_VALIDATE_EMAIL, ); print_r (filter_input_array (INPUT_GET, $filters ));
?> Output: Note:This example may not work as expected in the online IDE because it doesn’t support passing parameters in a GET or POST method. So, try running it on some PHP host server or localhost and passing parameter values using GET or POST method.Program 2:
Data received by POST method: $_POST = array (’product_id’ = >’ 234 < A > ’,’ component’ = > array (’10’),’ version’ = > ’< 2.8.9’,’ array2’ = > array (’45’,’ 1’), ’scalar_data’ = >’ 2’,);
// PHP program for using the filter_input_array() function error_reporting (E_ALL | E_STRICT); $args = array ( ’id’ = > FILTER_SANITIZE_ENCODED, ’ array1’ = > array ( ’filter’ = > FILTER_VALIDATE_INT, ’flags’ = > FILTER_REQUIRE_ARRAY, ’options’ = > array ( ’min_range’ = > 1, ’max_range’ = > 10 ) ), ’version’ = > FILTER_SANITIZE_ENCODED, ’noparameter’ = > FILTER_VALIDATE_INT, ’scalar_data’ = > array ( ’filter’ = > FILTER_VALIDATE_INT, ’flags’ = > FILTER_REQUIRE_SCALAR, ), ’array2’ = > array ( ’filter’ = > FILTER_VALIDATE_INT, ’flags’ = > FILTER_REQUIRE_ARRAY, ) ); $allinputs = filter_input_array (INPUT_GET, $args ); var_dump ( $allinputs ); echo "" ;
