Assigning a time to a number range

[Mutley]

I have some numbers:

 

$a = '26';

$b = '25.5';

$c = '24';

$d = '14';

...etc

 

What I wish to do, is for every .5 = 1 second from the highest number.

 

So, since $a is the highest number, I want it to echo something like this:

 

0s

+1s (this is $b)

+4s (this is $c)

+24s (this is $d)

 

if that makes sense?

 

Thanks.

There's probably a neater way of doing this, but I'd go with this:

 

<?php

// Array of timings to pass in to function
$times[] = "26";
$times[] = "25.5";
$times[] = "24";
$times[] = "14";

// Call to function
$secs = SecondDelay($times);

// Print out each timing difference in 'seconds'
foreach ($secs as $t){
   echo $t . "<br>";
}

// Funtion takes an unordered array of times and returns an ordered array of differences
function SecondDelay($timings){
   rsort($timings, SORT_NUMERIC);
   $highest = $timings[0];
   foreach ($timings as $time){
      $diff = floatval($highest - $time);
      $sdiff = $diff * 2;
      $seconds[] = '+' . $sdiff . 's';
   }
   return $seconds;
}

?>

 

If you want it to return the differences in the order you pass them to the function, then I can change that.

 

Hope this helps.

max() will find the highest

 

<?php


// Array of timings to pass in to function
$times[] = "26";
$times[] = "25.5";
$times[] = "24";
$times[] = "14";

$max = max($times);          // get highest val in the array

foreach ($times as $k=>$t)
{
    $times[$k] = sprintf('+%ds', ($max-$t)*2);
}

echo '<pre>', print_r($times, true), '</pre>';
?>

Thanks alot.

 

If I just wanted to print one, say the 3rd highest number, how would I do that?

 

Would I place [1] [2] etc in the [] and print it that way?

[Barand]

In that case, use Huggies sorted version and echo the 3rd

[Mutley]

I get a call to undefined function error with Huggies, I tried moving the function above where it is called but then it doesn't show any data.

 

Thanks.

[Barand]

worked fine when I ran it

[Mutley]

Thanks, I fixed it,

 

How would one echo the 3rd using that function?

[Barand]

echo $seconds[2];
