    $aaa 是一个没有定义过的变量,下面两种情况一个报错一个不报错,奇怪。。。

    // 不报错
    if ($aaa) {}
    
    // 报: Undefined variable: aaaa
    if ($aaa)

    跟你 php.ini 的 error_reporting 有关。
    ; Error Level Constants:
    ; E_ALL - All errors and warnings (includes E_STRICT as of PHP 5.4.0)
    ; E_ERROR - fatal run-time errors
    ; E_RECOVERABLE_ERROR - almost fatal run-time errors
    ; E_WARNING - run-time warnings (non-fatal errors)
    ; E_PARSE - compile-time parse errors
    ; E_NOTICE - run-time notices (these are warnings which often result
    ; from a bug in your code, but it's possible that it was
    ; intentional (e.g., using an uninitialized variable and
    ; relying on the fact it is automatically initialized to an
    ; empty string)
    ; E_STRICT - run-time notices, enable to have PHP suggest changes
    ; to your code which will ensure the best interoperability
    ; and forward compatibility of your code
    ; E_CORE_ERROR - fatal errors that occur during PHP's initial startup
    ; E_CORE_WARNING - warnings (non-fatal errors) that occur during PHP's
    ; initial startup
    ; E_COMPILE_ERROR - fatal compile-time errors
    ; E_COMPILE_WARNING - compile-time warnings (non-fatal errors)
    ; E_USER_ERROR - user-generated error message
    ; E_USER_WARNING - user-generated warning message
    ; E_USER_NOTICE - user-generated notice message
    ; E_DEPRECATED - warn about code that will not work in future versions
    ; of PHP
    ; E_USER_DEPRECATED - user-generated deprecation warnings
    ;
    ; Common Values:
    ; E_ALL (Show all errors, warnings and notices including coding standards.)
    ; E_ALL & ~E_NOTICE (Show all errors, except for notices)
    ; E_ALL & ~E_NOTICE & ~E_STRICT (Show all errors, except for notices and coding standards warnings.)
    ; E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR (Show only errors)
    ; Default Value: E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED
    ; Development Value: E_ALL
    ; Production Value: E_ALL & ~E_DEPRECATED & ~E_STRICT
