PHP: Calculate with cents

Question

I got the following problem: I got values like

2,50
1
2,99

Now I would like to separate them into 2 parts like this:

2 and 50
1 and 00
2 and 99


 $euro      =   explode('.', $item->price)[0]; 

 if(array_key_exists(1, explode('.', $item->price))) { 
    $cent   =   explode('.', $item->price)[1]; 
 }
 else
 { 
    $cent   =   "00"; 
 }

That's not the way I should do that I guess ;-)

There is another problem: Now I get the following values:

2 and 5
1 and 00
2 and 99

But it should be

2 and 50
1 and 00
2 and 99

why do you want to do that? to get 50, and not 5, you need to use strval() , so that it is cast as string, will number_format() work for you? or money_format() ? — Muhammed, Mar 04 '16 at 13:19
I need to do that because the webdesigner adds a special class to cent-values ;-) — MyFault, Mar 04 '16 at 13:24

You could do this, a decently short way of doing it:

$x = '2.55';

$a = explode('.',$x);

$euro = $a[0];
$cent = count($a) >= 2 ? $a[1] : '00';

Output:

2 and 55

Keep in mind that you cannot have two dots in your string at this point.

Try this:

<?php
$value = 2.50;
$big = ($value%10);
$small = ($value-$big)*100;
echo "Value: ".$value."\n";
echo "Big: ".$big."\n";
echo "Small: ".$small."\n";

If you have floats (or strings with a dot as decimal separator) as input:

$euro = (string)floor($input);
$cent = str_pad(($input - $euro) * 100, 2, "0", STR_PAD_LEFT);

In case you get strings with a comma as separator, prepend:

$input = str_replace(",", ".", $input);
