I am working on an OSCommerce site, and for the USPS Shipping method I want to convert the weight unit from Pounds to Ounces, but not getting the way how.
Can anyone help?
Given that 1 pound = 16 ounces, you can basically just multiply it by 16:
$pounds = 8;
$ounces = $pounds * 16;
echo $ounces; // 128
...but, if pounds is a float, you will probably want to round it. Since you are talking about shipping weights, you probably want to round up:
$pounds = 8.536;
$ounces = ceil($pounds * 16);
echo $ounces; // 137
You could put this into a function, like this:
function pounds_to_ounces ($pounds) {
return ceil($pounds * 16);
}
echo pounds_to_ounces(8); // 128
echo pounds_to_ounces(8.536); // 137

<?php
$seed = 'COPY_RAFFLE_SEED_HERE'; // Randomly generated seed [Seed:]
$raffle_id = 'COPY_RAFFLE_ID_HERE'; // Raffle ID [Raffle ID:]
$entries = 10; // Number of tickets [Entries count:]
/*
*
* Must +1 return value since it starts with 0
* 28 characters offset to get 4 characters from both hashes
*
*/
$randomNumber = (hexdec(substr(md5($seed) . md5($raffle_id), 28, 8)) % $entries)+1; // Must use +1 as it starts with 0
echo "Ticket with number #$randomNumber won";
apparently this is the code used for the giveaways, and i wanted to see how it works

function inchesTodecimal($inches){
return $decimal=inches/12;
}
I want convert inches to decimal like 11=0.917. I want to save 11 inches in database like decimal number 0.917.there is a problem occur when inches is 10.In float type .10=1
First you convert your feet Inches in to feet decimal like 5 feet and after point value convert it into decimal like 11=9.17 then insert into your database. When you want to show on user end you convert again feet Decimal to feet Inches like 5.917=>5.11 its simple hope you got what you want...
Here my simple code for conversion:
function feetInchesToDecimal($feetinches,$precision = 3){
list($feet,$inches) = explode(".",$feetinches);
$inches = preg_replace('/[^0-9.]/','',$inches);
$inches = $inches + ($feet * 12);
return round($inches /12,$precision);
}
function feetDecimalToInchs($feetdecimal){
$feet=(int)$feetdecimal;
$inches=round(($feetdecimal-$feet)*12);
$feetinches=$feet;
if($inches>0) $feetinches.=".".$inches;
return $feetinches;
}
echo feetInchesToDecimal(5.11); //5.917
echo feetDecimalToInchs(5.917); //5.11

I just want to know how to convert inch based on the integer inputted in the field.
For Example:
$int = $_POST['int']; //value 1
//computation here...
$inch = //formula
//echoing the inch
echo $inch;
If you want convert from centimeter can you use this source
function cm2inches($cm)
{
$inches = $cm/2.54;
$inches = $inches%12;
return sprintf('%d ins', $inches);
}
echo cm2inches(162);
You will have result
3 ins

I have this a record of: 10/2 * 100%
This is equal to 5
How does it save in PHP?
This not work:
($int1/$int2) * 100
Assuming $int1 = 10 and $int2 = 2, you'd have this sum;
echo (10 / 2) * 1; //1 being 100%
Which outputs 5.
http://codepad.org/twp2TduF
There is nothing wrong - it gives your desired result. I assume you were * 100, which would give 500.
Other percentages
* 0.25 = 25%
* 0.75 = 75%
..and so-on
Or refer to this answer
You cannot use percentage this way.
You will need to divide them by 100:
<?php
$int1 = 3;
$int2 = 6;
echo ($int1/$int2) * 100/100;
this above is 100%
and this:
echo ($int1/$int2) * 25/100;
is 25%

I have a bit of code but it is not echoing the correct answer, or in the correct format. I tried the round function but that didnt show anything
here is my code
$total_per_year = 308790;
$fat = $total_per_year / 3500;
echo $fat;
it is currently showing it as 0.088, but the correct answer is 88.2257142857
how can i do this so it round up to 88.2
The round function requires two parameters like so:
echo round($fat,1);
The second parameter being the amount of decimal places you require.
I have had issues previously with round not working as expected and I had to use number_format:
echo number_format((float)$fat,1,'.','');
With 1 being the decimal places required, the full stop being the decimal separator and '', being the thousand separator.
Use round()
echo round($fat, 1); //second argument is precision eg. decimals
See this for documentation: http://dk1.php.net/round
right, i worked this out now. I know i kept getting '0.088'. And this is wrong.
Its because i had it like this
$total_per_day = number_format($total_per_cup * $number_of_cups);
$total_per_year = number_format($total_per_day * 365);
$fat = round($total_per_year / 3500, 1);
echo $fat;
echo $total_per_year;
this is the correct code.
$total_per_cup = $type_calorie + $milk_calorie + $sugar_calorie;
$total_per_day = $total_per_cup * $number_of_cups;
$total_per_year = $total_per_day * 365;
$fat = $total_per_year / 3500;
echo json_encode(array('total'=> number_format($total_per_year) , 'perday' => number_format($total_per_day), 'fat'=> round($fat, 1)));
