[Resolved] Functions

ndorfnz

I am taking my first attempt at writing a function within PHP.

Been reading and reviewing info on them. Here is a question I cannot find answered.

I have some code that determines days, hours, minutes and seconds for totalnumber of seconds.

My page will display days, hours, minutes and seconds for the current week, month and year.

So based on the value of $totalsecs being sent to the function
(I plan to create, this seems like good use for one?)
for week, then month, then year... I need to return the values appropriately WITHOUT overwriting the previous.

For example I send $totalsecs of 147132 for the week.

My code returns 1 day, 16 hours, 52 minutes and 12 seconds.

Next I send $totalsecs of 547132 for the MONTH and my code returns 6 days, 7 hours, 58 min and 52 seconds.

I don't want to update the previous $variables that were set for week.

Do I handle this by simply including an IF statement and checking to determine if processing WEEK, MONTH or YEAR and have different variable names for each based on these?

This seems like a good scenario for a function, just not sure if I am on the right track???

Appreciate the insight!

Sincerely,

Gary

I need to return the values appropriately WITHOUT overwriting the previous.

I'm not clear on that part, but ...

goes out on a limb

The variables in a function are created when the function is called and destroyed when the function ends (unless you declare a global variable). So you wouldn't need to check for any repeated variables inside of the function.

Just think of user functions the same as you do pre-defined functions in PHP. Just plug your arguments in and get the results you want.

function Convert_Time($seconds)
{
$time = Do calculations
return $time;
}
$week = 147132;
$month = 547132;

$week_time = Convert_Time($week);
$month_time = Convert_Time($month);

Is it somthing like that? All then you would need are the two different vars calling the same function, $week_time would hold the weeks numbers and then you make a var called $month_time to hold the months info. So there is no information being lost. The original values of totalseconds would still be there same var names $week and $month.. I don't know if this is exactly what you are doing?

Thanks for the feedback...

Here is what a rough sample would be.

function Days($TOTALSECS)
{


$min = $totalsecs/60;
$hour =  $min/60;

$days = floor($hour/24);

blah, blah...


RETURN $days .':'. $hours .':'. $minutes .':'. $finalsecs;
}
?>

The function is always returning $days, $hours, $minutes and $finalsecs

Will it change my values for WEEK to what month returns, then my values for WEEK and MONTH for what YEAR returns within the page itself, outside of the function

Well... never mind! I got it!!! It works beautifully!!

I concatenated the values I wanted to return.

Where I was missing the boat was actually printing out the function with the value returned!!! I was trying to print out the actual variable...

Thanks for the direction...

WOW, this function is way cool!

As a suggestion, you could write the last line of the function as

return array(
	'days'    => $days,
	'hours'   => $hours,
	'minutes' => $minutes,
	'seconds' => $finalsecs);

You'd call the function in the same way:

$converted_month = days(547132);

Byt now $converted_month will be an array instead of a string. $converted_month['days'] will contain 6, $converted_month['hours'] will contain 7, and so on.

Doing this means you can work with all the bits separately if you want, without having to dig them out of the returned string first (and if at some point you want a string which has them all separated by ':', it would be $converted_month['days'] . ':' . $converted_month['hours'] . ':'...etc., - or even just join(':',$converted_month), because the bits are already in the right order in the array).
