README
Base class for exception with code and replacements.
Requirements:
- At least PHP 5.3.
- Loops\Autoloader package.
How to use it:
Autoloading
If you do not have composer, call bootstrap:
:::php
require $path_to_package.'/bootstrap.inc.php';
This library use package-oriented autoloading with a directory for package namespace (PSR-4) and underscore as directory separator for class names (PSR-0).
Extend
The \Loops\Exception\Base
class has been designed to be extended in order to
isolate an array of error codes for a specific exception.
:::php
class MyException extends \Loops\Exception\Base
{
public $_messages = array(
'CODE1' => 'Message 1' ,
'CODE2' => 'Message 2' ,
);
}
Throw
Then, you should be able to throw an exception using a code, and the message
argument as an array for sprintf()
replacements.
:::php
// create the exception class
class MyException extends \Loops\Exception\Base
{
public $_messages = array(
'ME101' => 'Invalid configuration' ,
'ME102' => 'Invalid value "%s"' ,
'ME103' => 'Invalid range "%02d;%02d"' ,
);
}
// invalid configuration
$e = new MyException( null , 'ME101' );
$m = $e->getMessage(); // result to 'Invalid configuration'
// invalid value
$e = new MyException( 'foo' , 'ME102' );
$m = $e->getMessage(); // result to 'Invalid value "foo"'
// invalid range
$e = new MyException( array( 0 , 42 ) , 'ME103' );
$m = $e->getMessage(); // result to 'Invalid range "00;42"'
Purpose
The two goals of this class are:
- manage all exception messages in a single place;
- force usage of a exception code for each exception messages.
Trace Ø
A getTrace0()
method is also available to fetch the line where the exception
has been thrown. This method comes with the getTrace0AsString()
one.
