Base36, Base64 or Base16 functions in PHP

So I noticed that your function would not use the first value in the array. base36(1, 36) would return 1, not 0.

I'm not sure if this goes against all baseX protocol, but here's a function that will utilize the first value of the array:

function base36($x, $base = NULL)
{
$baseChars = array('0', '1', '2', '3', '4', '5',
'6', '7', '8', '9', 'a', 'b',
'c', 'd', 'e', 'f', 'g', 'h',
'i', 'j', 'k', 'l', 'm', 'n',
'o', 'p', 'q', 'r', 's', 't',
'u', 'v', 'w', 'x', 'y', 'z'
);
$newVal = '';

if(is_null($base))
$base = count($baseChars);

while($value > 0)
{
$remainder = $value % $base;
$value = (($value - $remainder) / $base);
if($remainder == 0) # if the remiander is 0, set the offset to the last item in the $chars array, and decrement $x
{
$offset = $base - $remainder;
$value--;
}
else
{
$offset = $remainder - 1;
}
$newVal .= $baseChars[$offset];
}

return strrev($newVal);

}

Lol! Dude, you're joking right? Sure numbering systems start with 0, but 0 and 1 are not the same. If you return 1 as 0 then you no longer have 1 do you.

If we simply your modified function down to the basics and feed it a series of 0's and 1's, this would be the result of your function:

function returnBoolean($trueorfalse)
{
return false;
}

So to anyone reading this, use the original function, not the 'omfg 1 != 0!' function.
