error_log - for logging errors
throw Exception - for show stoppers
try/catch - for when you can handle a potential show stopper
custom error logging / messaging can easily be achieved with something
like this:
<?php
class Messenger
{
private static $_messages = array();
public static function addMessage( $string )
{
self::$_messages[] = $string;
if( $string instanceof Exception ) {
echo self::report();
}
}
public static function report()
{
return implode( PHP_EOL , self::$_messages );
}
}
set_exception_handler( 'Messenger::addMessage' );
Messenger::addMessage( 'little error report 1' );
Messenger::addMessage( 'little error report 2' );
Messenger::addMessage( 'little error report 3' );
throw new Exception( 'this will stop the script' );
// exception will kill the script; if you comment it out
// or wrap it in a try catch then you can keep going..
Messenger::addMessage( 'little error report 4' );
// try catch exceptions and report them like this..
try {
throw new Exception( 'we could catch this' );
} catch ( Exception $e ) {
Messenger::addMessage( $e );
}
Messenger::addMessage( 'little error report 5' );
// and when your done just echo it out or save it or..
echo Messenger::report();
Regards!
