php - Can't connect MySQL after deploying app on AppEngine -


can me fix , wrote simple code test mysql connection , work on locally can't connect mysql after deployed on app engine.

file app.yaml:

application: testmysql07  version: 1  runtime: php55  api_version: 1  threadsafe: yes  handlers:  - url: /favicon\.ico   static_files: favicon.ico   upload: favicon\.ico  - url: .*   script: main.php

file main.php:

<?php  $hostname     = "localhost";   $username     = "root";  $password     = "";  $databasename = "web_bb";   $conn = mysql_connect($hostname,$username,$password,$databasename) or die("can't connect mysql");      echo "successful </br>";  mysql_select_db($databasename,$conn);  ?>

sorry i'm not in speaking english

to connect local mysql database during development, you'll need

  1. enable billing app. allows use sockets connect remote servers.
  2. make sure local mysql database reachable internet, i.e. having correct firewall/nat settings in router.
  3. use public ip address $hostname in code.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
