    Javascript's .toString(16) in PHP - Stack Overflow

    programmeradmin3浏览0评论

    I'd like to do the same as JavaScript's .toString(16) but in PHP :

    var n = 200000002713419;
console.log(n.toString(16));

    This returns b5e6211de74b. How can I achieve the same with PHP ?

    Thanks a lot.

    • 3 dechex() will get you part of the way there, but note the limitations in the docs: php/manual/en/function.dechex.php – rjz Commented Jul 24, 2012 at 23:27
    • @zerkms, I couldn't sleep with the guilt of submitting one that would fail the given usage case :^) – rjz Commented Jul 24, 2012 at 23:33
    • 1 @rjz: among "good dreams" and "at least +40 rep points" I would choose the latter ;-) – zerkms Commented Jul 24, 2012 at 23:34

    Reset to default 16

    Use PHP's built-in function base_convert() or dechex():

    $hex = dechex(12321313); // bc0221
$hex = base_convert(4353454654, 10, 16); // 37c723e
