dec to string

[Jon Slaughter]

Is there any php functions to encode a decimal number(integer in this case)
into a binary string? Not convert it to a string but encode it. So 255 =
chr(255) and 256 = chr(1).chr(0) and not 255 = '255'.

Thanks,
Jon

No, I mean converting an int to its internal representation instead of its
string representation.

I wrote some methods to convert it but I'd like to use something faster if
possible:

function intDecStr($s)
{
$k = 1;
$l = 0;
for($i = 0; $i < 4; $i++)
{

$l = $l + $k*ord($s[$i]);
$k = $k*256;
}

return $l;
}
function intEncStr($i)
{
$s = "";
$q = 0;
do
{
$q++;
$m = $i % 256;
$s = $s.chr($m);
$i = floor($i/256);

} while ($q < 4);

return $s;
}

$i = 1343125;

$s = intEncStr($i);

$i = intDecStr($s);
