filter_var_array
(no version information, might be only in CVS)
filter_var_array -- Gets multiple variables and optionally filters them
Description
mixed
filter_var_array ( array data [, mixed definition] )
This function is useful for retrieving many values without
repetitively calling filter_var().
Parameters
data
An array with string keys containing the data to filter.
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
filter which specifies the filter type,
flags which specifies any flags that apply to the
filter, and options which 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.
Examples
Example 1. A filter_var_array() example
<?php
error_reporting(E_ALL | E_STRICT);
$data = 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_FORCE_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_FORCE_ARRAY,
)
);
$myinputs = filter_var_array($data, $args);
var_dump($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)
}
