I’m working on a project where we use a compiled Symfony DI container with a parameter bag for configuration parameters.
One issue I’ve been having with this is the inability to work with multiple environments without having to rebuild the container for every environment change or having a container classes for each environment.
When I was redeploying my IntoVPS Server and upgrading to the newest version of Ubuntu Server, I came across a number of issues with locales not being configured correctly. The error usually looks something like this:
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LANG = "en_US.UTF-8"
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
You’re getting this error because no locales have been configured. To fix it, firstly ensure that you have the locales package installed:
$ apt-get install locales
If locales is not installed, you will get a screen which will ask you which locales you wish to enable. If locales is already installed, then type the following to commands to regenerate locales.
$ locale-gen en_US en_US.UTF-8 en_AU en_AU.UTF-8 $ dpkg-reconfigure locales
If you want to use other locales, you can re-run the locale-gen and dpkg-reconfigure locales commands.
For some who are new to PHP 5 you may have heard about a PHP feature called SPL Autoload or Autoloading classes.
Ordinarily, when you write a class your code may look something like this:
<?php
require_once('../code/foo.php');
require_once('../code/baz.php');
class widget extends foo
{
public function event()
{
$baz = new baz();
}
}
Autoloading does away with the need to put require / include once to include class file by enabling you to attach a function that performs an action before a class is instantiated. SPL autoload works when you try to instantiate a class or use reflection on a class and only works when the class hasn’t already been loaded.
I’m currently working on a project which requires me to use MySQL from the command line. This presents a number of interesting issues for a developer who prefers a GUI to perform management functions.
I’ve started to compile a list of some of the more useful and maybe unknown MySQL commands.
