如何调整PHP错误报告级别

　　php.ini文件
　　; error_reporting is a bit-field.  Or each number up to get desired error
　　; reporting level
　　; E_ALL             - All errors and warnings (doesn't include E_STRICT)
　　; 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's 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
　　;
　　; Examples:
　　;
　　;   - Show all errors, except for notices and coding standards warnings
　　;
　　;error_reporting = E_ALL & ~E_NOTICE
　　;
　　;   - Show all errors, except for notices
　　;
　　;error_reporting = E_ALL & ~E_NOTICE | E_STRICT
　　;
　　;   - Show only errors
　　;
　　;error_reporting = E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR
　　;
　　;   - Show all errors, except coding standards warnings
　　;
　　error_reporting = E_ALL & ~E_NOTICE & ~E_STRICT
　　; Print out errors (as a part of the output).  For production web sites,
　　; you're strongly encouraged to turn this feature off, and use error logging
　　; instead (see below).  Keeping display_errors enabled on a production web site
　　; may reveal security information to end users, such as file paths on your Web
　　; server, your database schema or other information.
　　;
　　; possible values for display_errors:
　　;
　　; Off          - Do not display any errors 
　　; stderr       - Display errors to STDERR (affects only CGI/CLI binaries!)   
　　; On or stdout - Display errors to STDOUT (default)
　　;  
　　; To output errors to STDERR with CGI/CLI:              
　　;display_errors = "stderr"
　　;
　　; Default
　　;
　　display_errors = On
