I can get the PHP web server to successfully encrypt the data and send it via a socket but I cannot get the java application to successfully decrypt the message.

php error-handling error-reporting error-suppression e-notices
tl;dr – Is there an effective way to manage the error reporting level of PHP when working in a very strict environment, given certain processes would be made easier with a less strict level?Alright; first off, I don’t believe “error suppression” is a solution. I (am reasonably certain that I) have never used the @ error supression operator, and have no intention of doing so. I take advantage of set_error_handler() and ErrorException (or some derivation of) and I develop in an error_reporting(-1)

php error-handling
By old habit I’ve always used require over include. Basicly the two functions are exactly the same – besides require throws an error if the file does not exist and thus stops the script – where include will just throw a warning and continue on with the script as if nothing happened.Normally when I dynamically include files I use something along the lines of if file_exists then require it. Looking like this:<?php if (file_exists($file)) { require $file; } else { /*error handling*/ } ?>As fa

php database error-handling firebird
I am currently building a database handler. Running on PHP 5.4.16 on top of a Firebird database.When I have made a prepared statement, I need to execute the SQL with the arguments. I made this function:private function assignParameters($args) {return call_user_func_array(‘ibase_execute’,$args); }The problem is when I make an error in the args (not giving it the values that are expected), I expect the return to give false(error). ibase_execute normally returns false when an error has occurred.But

android bluetooth try-catch
I’m looking for a way to gracefully disconnect from a Bluetooth device. I used the BluetoothChat sample and the problem is that when you intend to disconnect you simply call socket.close() from the cancel() method, but then the IntputStream.read() will inevitably throw an exception.I need this mainly because it acts as a “lost connection” failsafe as well, so when I try to disconnect I get two signals: graceful disconnection followed by lost connection signal.Basically what I’m trying to do is n

I have several json objects that come from the server. At the moment, I’m using the browsers’ json functionalities (my application only supports modern browsers) to parse json to objects.

java try-catch
So just got into the basics of try-catch statements in java. Im still a bit confused on some differences within the syntax. Here is the code im trying to analyze and understand. Also, whats the difference between using try then catch(Exception e) as compared to saying just throws…or throw new… From my understanding, a try catch is basically a way to handle the error by outputting a message or passing to another method. However, i think im stuck on the syntax aspect of it. Any constructive co

I am a java newbie, my question is about try-catch blocks on a simple division by zero example. You see the first line of try? If I cast any of those two variables to the double the program does not recognize the catch block. In my opinion, whether I cast or not only the catch block must be executed. What is wrong on this code? Thanks.public static void main(String[] args) {int pay=8,payda=0; try {double result=pay/(double)payda; // if I cast any of the two variables, program does not recogniz
