Answer 1

如果发生异常，

$e将仅：

try {
   throw new Exception('foo');
} catch (Exception $e) {
   // do nothing
}

try {
   $foo = 1; // no exception occurs
} catch (Exception $f) {
   // do nothing
}

var_dump($e); // spits out the exception info
var_dump($f); // undefined variable, because no exception occured to define it

Answer 2

将你的if语句放在Exception

中

即。 catch (Exception $e) { if ($e......) { blah vlah blah.... } }

未定义的变量$ e
