Example Usage:
<?php
$_GET['A']['a'] = ' CORRECT(including some spaces) ';
$_GET['A']['b'] = ' CORRECT(including some spaces) ';
$_GET['A']['c'] = "Invalid UTF-8 sequence: \xe3\xe3\xe3";
$_GET['A']['d']['invalid_structure'] = 'INVALID';
$_GET['B']['a'] = ' CORRECT(including some spaces) ';
$_GET['B']['b'] = "Invalid UTF-8 sequence: \xe3\xe3\xe3";
$_GET['B']['c']['invalid_structure'] = 'INVALID';
$_GET['B']["Invalid UTF-8 sequence: \xe3\xe3\xe3"] = 'INVALID';
$_GET['C']['a'] = ' CORRECT(including some spaces) ';
$_GET['C']['b'] = "Invalid UTF-8 sequence: \xe3\xe3\xe3";
$_GET['C']['c']['invalid_structure'] = 'INVALID';
$_GET['C']["Invalid UTF-8 sequence: \xe3\xe3\xe3"] = 'INVALID';
$_GET['unneeded_item'] = 'UNNEEDED';
var_dump(filter_struct_utf8(INPUT_GET, array(
'A' => array(
'a' => '',
'b' => FILTER_STRUCT_TRIM,
'c' => '',
'd' => '',
),
'B' => FILTER_STRUCT_FORCE_ARRAY,
'C' => FILTER_STRUCT_FORCE_ARRAY | FILTER_STRUCT_TRIM,
)));
?>
Example Result:
array(3) {
["A"]=>
array(4) {
["a"]=>
string(36) " CORRECT(including some spaces) "
["b"]=>
string(30) "CORRECT(including some spaces)"
["c"]=>
string(0) ""
["d"]=>
string(0) ""
}
["B"]=>
array(3) {
["a"]=>
string(36) " CORRECT(including some spaces) "
["b"]=>
string(0) ""
["c"]=>
string(0) ""
}
["C"]=>
array(3) {
["a"]=>
