Bug description: decbin() is not returning the correct value
Description:
------------
I wrote my own little function that can take numbers and make turn them
into numbers of other bases. When I ran a few tries with binary, I began
to notice that PHP's decbin() was not matching up with mine. Easily
proven, mine was correct.
Reproduce code:
---------------
echo dec2base(4728937489, 2) . "\n";
echo decbin(4728937489);
function dec2base($int, $base)
{
while ($int >= 1)
{
$ret .= $int % $base;
$int = $int / $base;
}
return strrev($ret);
}
Expected result:
----------------
100011001110111011101110000010001
100011001110111011101110000010001
Actual result:
--------------
100011001110111011101110000010001
11001110111011101110000010001
