Try Catch 无法与 PHP 中的 require_once 一起使用？

我不能做这样的事吗？

try {
    require_once( '/includes/functions.php' );      
}
catch(Exception $e) {    
    echo "Message : " . $e->getMessage();
    echo "Code : " . $e->getCode();
}

没有回显错误，服务器返回 500。

你可以这样做include_once or file_exists:

try {
    if (! @include_once( '/includes/functions.php' )) // @ - to suppress warnings, 
    // you can also use error_reporting function for the same purpose which may be a better option
        throw new Exception ('functions.php does not exist');
    // or 
    if (!file_exists('/includes/functions.php' ))
        throw new Exception ('functions.php does not exist');
    else
        require_once('/includes/functions.php' ); 
}
catch(Exception $e) {    
    echo "Message : " . $e->getMessage();
    echo "Code : " . $e->getCode();
}
