PHP:try{}catch(){}捕获不到异常？？怎回事啊

Question

if(function_exists('spl_autoload_register')){ try { spl_autoload_register(function ($name) { if(file_exists($name.'.php')){ require_once $name.'.php'; }else{ throw new Exception('undefined this'); } }); }catch (Exception $e){ echo $e->getMessage(); exit; } } class main{ public function myf(){ $test = new tests; $test->show(); } }

Answer 1

你的 catch, catch 的错误是spl_autoload_register 是否能注册函数成功

try {
    $test = new tests;
    $test->show();
} catch (Exception $e) {
    echo $e->getMessage();
    exit;
}

这样才能有你想要的结果
