Funcții ale tablourilor (Array)
Unicode example;
<?php
function array_change_key_case_unicode($arr, $c = CASE_LOWER) {
$c = ($c == CASE_LOWER) ? MB_CASE_LOWER : MB_CASE_UPPER;
foreach ($arr as $k => $v) {

}
return $ret;

$arr = array("FirSt" => 1, "yağ" => "Oil", "şekER" => "sugar");
print_r(array_change_key_case($arr, CASE_UPPER));
print_r(array_change_key_case_unicode($arr, CASE_UPPER));
?>
Array

array_change_key_case
(PHP 4 >= 4.2.0, PHP 5)
array_change_key_case — Modifică toate cheile dintr-un tablou
Descrierea
array array_change_key_case
( array
$input
[, int $case = CASE_LOWER
] )
Întoarce un tablou cu toate cheile din input
transferate în caractere minuscule sau majuscule. Indicii-numere rămân precum
sunt.
Parametri
-
input -
Tabloul asupra căruia se lucrează
-
case -
Poate lua valoarea
CASE_UPPERsauCASE_LOWER(implicit)
Valorile întoarse
Întoarce un tablou cu cheile transferate în caractere minuscule sau majuscule,
sau FALSE dacă input nu este un tablou.
Erori/Excepții
Aruncă E_WARNING dacă input nu
este un tablou.
Exemple
Example #1 Exemplu array_change_key_case()
<?php
$input_array = array("FirSt" => 1, "SecOnd" => 4);
print_r(array_change_key_case($input_array, CASE_UPPER));
?>
Exemplul de mai sus va afișa:
Array
(
[FIRST] => 1
[SECOND] => 4
)
Note
Notă:
Dacă un tablou are indici care vor deveni la fel odată ce se va rula această funcție (de ex. "keY" și "kEY"), valoarea cea mai de pe urmă din tablou se va suprapune peste ceilalți indici.

Script to change case of sub-arrays keys to lower . It works well for me. hope it helps.
<?php
$array=array("First"=>"val1","SecoNd"=>"val2",
"third"=>array("third-INner1"=>"val3.1"),
"fourth"=>array("FouthINNer1"=>"val4.1","FourthINNER2"=>"val4.2"));
print_r($array);
$key=array_keys($array);
foreach($key as $ki)
{
$klower=strtolower($ki);
$val=$array[$ki];
if(is_array($val))
{
foreach($val as $kinner=>$vinner)
{
$tl=strtolower($kinner);
unset($val[$kinner]);
$val[$tl]=$vinner;
}
}
unset($array[$ki]);
$array[$klower]=$val;
}
echo "<br> After Changing Key to-LowerCase : <br>";
print_r($array);
?>

<?php
// improving the previous script
function ack_r3(&$array, $case=CASE_LOWER, $flag_rec=false)

$array = array_change_key_case($array, $case);
if ( $flag_rec ) {
foreach ($array as $key => $value) {
if ( is_array($value) ) {
ack_r3($array[$key], $case, true);
}
}
}
}
// same of array_change_key_case
$arr = array('ID' => 1, 'NAME'=> 'Luis', 'Contact' => array('PHONE' => '3010-7148', 'E-MAIL' => 'luis@net.com') );
ack_r3($arr, CASE_LOWER,false);
var_dump($arr);
$arr = array('ID' => 1, 'NAME'=> 'Luis', 'Contact' => array('PHONE' => '3010-7148', 'E-MAIL' => 'luis@net.com') );
ack_r3($arr, CASE_LOWER,true);
var_dump($arr);

outputs:
array(3) {

Script to change case of sub-arrays keys:
<?php
function arrKey2Lower(&$arrVals) {
foreach( $arrVals as $key => $item ) {
$key2 = strtolower($key);
if ( $key2 != $key) {
unset($arrVals[$key]);
$arrVals[$key2]=$item;
$key=$key2;
}
if ( is_array($item) ) { arrKey2Lower($arrValores[$key]); }
}
}
$arr = array('ID' => 1, 'NAME'=> 'Luis', 'Contact' => array('PHONE' => '3010-7148', 'E-MAIL' => 'luis@net.com') );
arrKey2Lower($arr);
var_dump($arr);
?>
outputs:
array(3) {
["id"]=>
int(1)
["name"]=>
string(4) "Luis"
["contact"]=>
array(2) {
["phone"]=>
string(9) "3010-7148"
["e-mail"]=>
string(12) "luis@net.com"
}

Simple function to change multidimensional array's all values to uppercase. If you would like to change to lowercase then change "mb_strtoupper" to "mb_strtolower". It works perfect for me ;)
<?php
function change_case_recursive($arr){
foreach ($arr as $key=>$val){
if (!is_array($arr[$key])){
$arr[$key]=mb_strtoupper($arr[$key]);
}else{
$arr[$key]=change_case_recursive($arr[$key]);
}
}
return $arr;
}
?>

Same as array_change_key_case only with the values. This should really be part of PHP!
<?php
/**
* @brief Returns an array with all values lowercased or uppercased.
* @return array Returns an array with all values lowercased or uppercased.
* @param object $input The array to work on
* @param int $case [optional] Either \c CASE_UPPER or \c CASE_LOWER (default).
*/
function array_change_value_case(array $input, $case = CASE_LOWER) {
switch ($case) {
case CASE_LOWER:
return array_map('strtolower', $input);
break;
case CASE_UPPER:
return array_map('strtoupper', $input);
break;
default:
trigger_error('Case is not valid, CASE_LOWER or CASE_UPPER only', E_USER_ERROR);
return false;
}
}
?>

Below is a recursive version of this function.
<?php
/**

* @param array $input
* @param integer $case
*/
function array_change_key_case_recursive($input, $case = null){
if(!is_array($input)){
trigger_error("Invalid input array '{$array}'",E_USER_NOTICE); exit;
}
// CASE_UPPER|CASE_LOWER
if(null === $case){
$case = CASE_LOWER;
}
if(!in_array($case, array(CASE_UPPER, CASE_LOWER))){
trigger_error("Case parameter '{$case}' is invalid.", E_USER_NOTICE); exit;
}
$input = array_change_key_case($input, $case);
foreach($input as $key=>$array){
if(is_array($array)){
$input[$key] = array_change_key_case_recursive($array, $case);
}
}
return $input;
}
?>

Basically this is the function if your version is lower than 4.2.0
<?php
if ( !defined('CASE_LOWER') )define('CASE_LOWER', 0);
if ( !defined('CASE_UPPER') )define('CASE_UPPER', 1);
if(!function_exists("array_change_key_case")){
function array_change_key_case($input, $case=0){
if(!is_array($input))return FALSE;
$product = array();
foreach($input as $key => $value){
if($case){ //Upper
$key2 = ( (is_string($key)) ? (strtoupper($key)) : ($key) );
$product[$key2] = $value;
}
else{ //Lower
$key2 = ( (is_string($key)) ? (strtolower($key)) : ($key) );
$product[$key2] = $value;
}
}
return $product;
}/* endfunction array_change_key_case */
}/* endfunction exists array_change_key_case*/

I just changed the code a little bit so you havent got a code that repeats itself.
<?php
function array_change_key_case_secure($array = array(), $case = CASE_UPPER){
$secure = array();
$functionWrap = array(CASE_UPPER => 'strtoupper',
CASE_LOWER => 'strtolower');
foreach($array as $key => $val){
if(isset($functionWrap[$key])){
$key = $functionWrap[$case]($key);
$secure[$key][] = $val;
} else {
die('Not a known Type');
}
}
foreach($secure as $key => $val){
if(count($secure[$key]) == 1){
$secure[$key] = $val[0];
}
}
return $secure;
}
$myArray = array('A' => 'Hello',
'B' => 'World',
'a' => 'how are you?');
print_r($myArray);
$myArray = array_change_key_case_secure($myArray);
print_r($myArray);
/*
Array
(
[A] => Hello
[B] => World
[a] => how are you?
)
Array
(
[A] => Array
(
[0] => Hello
[1] => how are you?
)
