if you generate form select from an array, you probably want to keep your array keys and order
intact,
if so you can use ArrayMergeKeepKeys(), works just like array_merge :
array ArrayMergeKeepKeys ( array array1 [, array array2 [, array ...]])
but keeps the keys even if of numeric kind.
enjoy
<?
$Default[0]='Select Something please';
$Data[147]='potato';
$Data[258]='banana';
$Data[54]='tomato';
$A=array_merge($Default,$Data);
$B=ArrayMergeKeepKeys($Default,$Data);
echo '<pre>';
print_r($A);
print_r($B);
echo '</pre>';
Function ArrayMergeKeepKeys() {
$arg_list = func_get_args();
foreach((array)$arg_list as $arg){
foreach((array)$arg as $K => $V){
$Zoo[$K]=$V;
}
}
return $Zoo;
}
//will output :
Array
(
[0] => Select Something please
[1] => potato
[2] => banana
[3] => tomato
)
Array
(
[0] => Select Something please
[147] => potato
[258] => banana
[54] => tomato
)
?>
