Displaying numbers with 2 digits

Michael

Hi,

I have something like :
$c=$a+$b;
echo $c,

The thing is, i want the result to be a 2 digit number (ie 05 and not 5).
How 2 ?

Thanks in advance.

$c = $a+$b;
printf('%2u',$c);

...or..

$c = sprintf('%2u',$a+$b);
echo $c;

See the documentation for printf() and sprintf() in the PHP manual.

+ is an arithmetic operator
http://www.php.net/manual/en/languag...arithmetic.php

I think you want the

.. string operator
http://www.php.net/manual/en/languag...ors.string.php
<?php
$as = "0";
$bs = "5";
$cs = "0";

$an = 0;
$bn = 5;
$cn = 0;

echo $as + $bs; ### 5
echo $as . $bs; ### 05
echo $bs + $cs; ### 5
echo $bs . $cs; ### 50

echo $an + $bn; ### 5
echo $an . $bn; ### 05
echo $bn + $cn; ### 5
echo $bn . $cn; ### 50
?>
Or, if I misunderstood you, use the number_format() or printf()
functions
http://www.php.net/number_format
http://www.php.net/printf

Using %2u results in a leading space, not a leading zero as stated
in the requirement. See the documentation for sprintf() to find
out how to get leading zeros.

The 'u' IIRC, is a symbol for 'UNSIGNED' INTs.
