string - PHP encoding to 64 char length -


to generate pretty urls take 2 strings

-unix timestamp

-string (length 16 chars)

is there way use both , encode them string fixed length of 64 chars?

you can use str_pad() function along base64_encode string:

http://php.net/manual/en/function.str-pad.php

this functions returns input string padded on left, right, or both sides specified padding length. if optional argument pad_string not supplied, input padded spaces, otherwise padded characters pad_string limit.

example:

$string = urlencode(base64_encode($string)); $padded = str_pad($tstamp."_".$string."_", 64, "0");

your url like:

/order/timestamp_base64string_00000..../

each _ separator gets part of url need, have urldecode() base64_decode() string.

i suggest rather use sessions (cookies) maintain such information page another, or use intermediary storage system ids used in urls.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
