------------------------------------

function __autoload_my_classes($classname)

{

# ... your logic to include classes here

}

spl_autoload_register('__autoload_my_classes');

12. 用set_error_handle 去捕获错误并输出, 级别自己定

set_error_handle(callback,level)

function callback(int $errno , string $errstr [, string $errfile [, int $errline [, array $errcontext ]]] ){

}

function dealErrorHandler($errno,$errstr,$errfile,$errline)

{

switch($errno){

case E_USER_ERROR:

echo "error [$errno] $errstr fatal error on line $errline in file $errfile";

break;

case E_USER_WARNING:

echo "my warning [$errno] $errstr":

break;

case E_USER_NOTICE:

echo "my notice[$errno] $errstr";
