Hi,

i use php4. In php4 the function str_split is missing, but this func is
required for lib/Horde/IMAP/ACL/rfc2086.php, so i added this func to
rfc2086.php:

if(!function_exists('str_split')){
   function str_split($string,$split_length=1){
       $count = strlen($string); 
       if($split_length < 1){
           return false; 
       } elseif($split_length > $count){
           return array($string);
       } else {
           $num = (int)ceil($count/$split_length); 
           $ret = array(); 
           for($i=0;$i<$num;$i++){ 
               $ret[] = substr($string,$i*$split_length,$split_length); 
           } 
           return $ret;
       }     
   } 
}
