filter_input_array
Gets multiple variables from outside PHP and optionally filters them
(PHP 5 >= 5.2.0, PECL filter:0.11.0)
mixed filter_input_array ( int type [, mixed definition] )
This function is useful for retrieving many values without repetitively calling filter_input().
Parameters
- type
One of
INPUT_GET,INPUT_POST,INPUT_COOKIE,INPUT_SERVER,INPUT_ENV,INPUT_SESSION, orINPUT_REQUEST.- 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, andoptionswhich 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.
Return Values
An array containing the values of the requested variables on success, or FALSE
on failure. An array value will be FALSE if the filter fails, or NULL if
the variable is not set. Or if the flag FILTER_NULL_ON_FAILURE
is used, it returns FALSE if the variable is not set and NULL if the filter
fails.
Examples
Example 674. A filter_input_array() example
<?php
error_reporting(E_ALL | E_STRICT);
/* data actually came from POST
$_POST = array(
'product_id' => 'libgd<script>',
'component' => '10',
'versions' => '2.0.33',
'testscalar' => array('2', '23', '10', '12'),
'testarray' => '2',
);
*/
$args = array(
'product_id' => FILTER_SANITIZE_ENCODED,
'component' => array('filter' => FILTER_VALIDATE_INT,
'flags' => FILTER_REQUIRE_ARRAY,
'options' => array('min_range' => 1, 'max_range' => 10)
),
'versions' => FILTER_SANITIZE_ENCODED,
'doesnotexist' => FILTER_VALIDATE_INT,
'testscalar' => array(
'filter' => FILTER_VALIDATE_INT,
'flags' => FILTER_REQUIRE_SCALAR,
),
'testarray' => array(
'filter' => FILTER_VALIDATE_INT,
'flags' => FILTER_REQUIRE_ARRAY,
)
);
$myinputs = filter_input_array(INPUT_POST, $args);
var_dump($myinputs);
echo "\n";
?>The above example will output:
array(6) {
["product_id"]=>
array(1) {
[0]=>
string(17) "libgd%3Cscript%3E"
}
["component"]=>
array(1) {
[0]=>
int(10)
}
["versions"]=>
array(1) {
[0]=>
string(6) "2.0.33"
}
["doesnotexist"]=>
NULL
["testscalar"]=>
bool(false)
["testarray"]=>
array(1) {
[0]=>
int(2)
}
}
