CodeIgniter中设计一个全局exception hook博客分类:
在CodeIgniter中,当发生异常时,经常要通知系统管理员,因此有必要在全局的高度上 捕捉异常,因此可以写一个hook, 比如在config目录的hook.php中,加入: $hook['pre_controller'][] = array( 'class' => 'ExceptionHook', 'function' => 'SetExceptionHandler', 'filename' => 'ExceptionHook.php', 'filepath' => 'hooks' ); 然后在应用的hook目录下,编写ExceptionHook.php <?php
class ExceptionHook { public function SetExceptionHandler() { set_exception_handler(array($this, 'HandleExceptions')); } public function HandleExceptions($exception) {
$msg ='Exception of type \''.get_class($exception).'\' occurred with Message: '.$exception->getMessage().' in File '.$exception->getFile().' at Line '.$exception->getLine();
$msg .="\r\n Backtrace \r\n"; $msg .=$exception->getTraceAsString();
log_message('error', $msg, TRUE);
mail('dev-mail@example.com', 'An Exception Occurred', $msg, 'From: test@example.com');
} ?>
class ExceptionHook { public function SetExceptionHandler() { set_exception_handler(array($this, 'HandleExceptions')); } public function HandleExceptions($exception) {
$msg ='Exception of type \''.get_class($exception).'\' occurred with Message: '.$exception->getMessage().' in File '.$exception->getFile().' at Line '.$exception->getLine();
$msg .="\r\n Backtrace \r\n"; $msg .=$exception->getTraceAsString();
log_message('error', $msg, TRUE);
mail('dev-mail@example.com', 'An Exception Occurred', $msg, 'From: test@example.com');
} ?>
