Question

How do I create a php function that calculates, and then generates an array that represents both imperial, and its equivalent metric measurements(for humans) for any given range(say 4ft to 7ft)?.

For example:

Array
(
    [1] => 4'8"(142cm)
    [2] => 4'9"(144.5cm)
    [3] => 4'10"(147cm)
)

…and so on. The same example for weight(pounds/kilos) also. If someone could give me a head start on this, I’d appreciate it.

this might point you in the right direction.. have not tested but it should be enough to get you started. very simple concept. I got you started with the feet+ inches strings – now you should be able figure out how to get the meters in there.

// $startHeight and $endHeight are in inches

function createRange($startHeight,$endHeight){

// calculate the difference in inches between the heights
$difference = $endHeight - $startHeight;

// create an array to put the results in
$resultsArray; 

//create a loop with iterations = $difference

for($i=0;$i<$difference;$i++)
{
    // create the current height based on the iteration
    $currentHeight = $startHeight + $i;

    // convert the $currentHeight to feet+inches
    // first find the remainder, which will be the inches
    $remainder = ($currentHeight % 12);
    $numberOfFeet = ($currentHeight - $remainder)/12;

    // build the feet string
    $feetString = $numberOfFeet.'&apos;'.$remainder.'&quot;';

    // now build the meter string using a similar method as above
    // and append it to $feetString, using a conversion factor

    // add the string to the array
    $resultsArray[] = $feetString;

}

// return the array
return $resultsArray;

}
