php time help again

[mike1313]

Ok I want a percent returned. I have a script that executes at roughly 6 am. How can I find out based on the current time how much of a percent it is until 6 am. As it gets closer to 6 am the % gets higher.

Percent of what? of the day? percent of time left since the last 6 am?

[mike1313]

Percentage based on the time now until 6 am with the % getting higher as it gets closer to 6 am once at 6 am its 100% once it hits 6:01 am it starts over again at 0%

[mike1313]

that or how can I find 6 am server time - current time and turn that into mins?

Percent of what? of the day? percent of time left since the last 6 am?

 

i'm pretty sure that's what he's looking for. this is more of a math question than a PHP question. i'd start with the number of minutes in a day: 1440. then i'd get the current time using time() and convert it into minutes. then, subractthe current time from 1440, and convert it into percent. boom. you're done.

something like:

<?php
        $current_time = time() / 60;
        $total_time = 1440;

        $time_left = number_format((($total_time / $current_time) / 100), 2);
?>

[mike1313]

that just returns 0.00.

[boo_lolly]

<?php
        $current_time = time() / 60;
        $total_time = 1440;

        $time_left = number_format((($total_time - $current_time) / 100), 2);
?>

[mike1313]

no thats returned negative. I had this....

 

<? 
$sixamtime = ((((time() / 60) / 24) / 3600) / 7);
$six = 60 * 6;
        $total_time = 1440;

        $percentage = round((($total_time / $sixamtime) / 100) * 100);

echo "$percentage";
?>

[boo_lolly]

and did that work???

 

also, why are you dividing by 100 and then multiplying by 100?

[mike1313]

well it was returning just aplain ole 44

[mike1313]

is there a way to divide the time stamp for 6 am? that way I could take the current timestamp - 6amstamp and turn it into a %?

[boo_lolly]

what do you mean divide the timestamp for 6am?

[mike1313]

I mean is there a way to find out what a certain part of the timestamp will be for 6 am, then find the current hour subtract the 2 and make it into a % that way?

[boo_lolly]

time() returns the total amount of minutes from 12am. so, if it's 1am, time() will return 60. does that make sense?

I think this may be what you are looking for.  Except if it's 0600 it will display 0%.  It will also probably display 100% prematurely because of the rounding.  Just force it to round down using the floor function, then it won't display 100% from 0545 until 0559, but will display 99% instead.

 

//hour: int from 0 - 23
$control_hour = 6;

//minute: int from 0 - 59
$control_minute = 0;

$current_hour = date("G");
$current_minute = date("i");

$minutes_in_day = 24 * 60;

$expired = (($current_hour * 60) + $current_minute) - (($control_hour * 60) + $control_minute);
$expired = ($expired < 0) ? $expired + $minutes_in_day : $expired;

echo round(($expired / $minutes_in_day) * 100) . "%";
