Question

im not sure this is a good question to post but here is my issue. I have an if statement that is getting way too long and i was wondering if there is some other kind of syntax to shorten it out:

if (($time1 <= $one_day)&&
    ($time2 <= $one_day)&&
    ($time3 <= $one_day)&&
    ($time4 <= $one_day)&&
    ($time5 <= $one_day)&&
    ($time1 != NULL)&&
    ($time2 != NULL)&&
    ($time3 != NULL)&&
    ($time4 != NULL)&&
    ($time5 != NULL)){
    //do sometihng
}

this is one example but i have a similar one that goes up to ..&&($time15 <= $one_day).

the statement is pretty self explanatory, $time1, $time2, etc can come back empty so i have to check if they are NULL or not

any ideas?

thanks

You can put the common stuff in a function:

function validate_time($time, $one_day) {
    return $time <= $one_day && $time != NULL;
}
if (validate_time($time1, $one_day) &&
    validate_time($time2, $one_day) &&
    validate_time($time3, $one_day) &&
    validate_time($time4, $one_day) &&
    validate_time($time5, $one_day)) {
    // do something
}

You may want to refactor code and eliminate the need for copying & pasting those checks. Another way to get the job done:

while (true) {
    foreach (array($time1, $time2, $time3, $time4, $time5) as $time) {
        if ($time > $one_day || $time == NULL) {
            break 2;
        }
    }
    // do something
    break;
}

The above could be put in a function as well which would make the while-loop and break keyword redundant. Replace break 2 by return then.
