Sorry for my english...
I wrote a function to get keys of arrays recursivelly...
<?php
function recursive_keys($input, $search_value = null){
$output = ($search_value !== null ? array_keys($input, $search_value) : array_keys($input)) ;
foreach($input as $sub){
if(is_array($sub)){
$output = ($search_value !== null ? array_merge($output, recursive_keys($sub, $search_value)) : array_merge($output, recursive_keys($sub))) ;
}
}
return $output ;
}
?>
I hope it will be usefull
Regards
