Hello Everyone! This is my code ************************************************ if (count($array_id)==1) { $string_id=$array_id; } else { $string_id= implode(":",$array_id); } ************************************************ I've been testing it for three days and never had an error, now it comes and goes. Do you know what could be wrong? $array_id is an array of integers Thanks in advance
