input_get_args
(no version information, might be only in CVS)
input_get_args -- Gets multiple variables from outside PHP and optionally filters them
Description
mixed
input_get_args ( int type, array definition [, array data] )
| Warning |
This function is
EXPERIMENTAL. The behaviour of this function, the
name of this function, and anything else documented about this
function may change without notice in a future release of PHP.
Use this function at your own risk. |
This function is useful for retrieving a large amount of values without
repetitively calling input_get().
Parameters
- type
One of INPUT_GET, INPUT_POST,
INPUT_COOKIE, INPUT_SERVER,
INPUT_ENV, INPUT_SESSION, or
INPUT_DATA.
- 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.
- data
Data to filter. Used if the type parameter is
set to INPUT_DATA.
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 input_get_args() 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',
);
$args = array(
'product_id' => FILTER_SANITIZE_ENCODED,
'component' => array('filter' => FILTER_VALIDATE_INT,
'flags' => FILTER_FLAG_ARRAY,
'options' => array('min_range' => 1, 'max_range' => 10)
),
'versions' => FILTER_SANITIZE_ENCODED,
'doesnotexist' => FILTER_VALIDATE_INT,
'testscalar' => array(
'filter' => FILTER_VALIDATE_INT,
'flags' => FILTER_FLAG_SCALAR,
),
'testarray' => array(
'filter' => FILTER_VALIDATE_INT,
'flags' => FILTER_FLAG_ARRAY,
)
);
//$myinputs = input_get_args(INPUT_POST, $args);
$myinputs = input_get_args(INPUT_DATA, $args, $data);
var_dump($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)
}
