PHP错误提示的关闭方法详解
最简单的办法就是直接在php程序代码中加入下面代码:
复制代码 代码如下:
error_reporting(E_ALL^E_NOTICE^E_WARNING);
可以关闭所有notice 和 warning 级别的错误。
把这个语句放在您脚本的功用包含文件中,通常为config.php 或者conn.php 中就可以控制输出了。
当然我也也可以在php.ini中进行设置了方法如下
打开PHP安装目录下的php.ini文件
找到display_errors = On 修改为 display_errors = off
注意:如果你已经把PHP.ini文件复制到windows目录下,那么必须同时把c:windows/php.ini里的display_errors = On 修改为display_errors = off
PHP .ini中display_errors = Off失效的解决
问题:
PHP 设置文件php .ini中明明已经设置display_errors = Off,但是在运行过程中,网页上还是会出现错误信息。
解决:
打开PHP安装目录下的php.ini文件
找到log_errors = off 修改为 log_errors = on
找到error_log = filename 修改为 error_log="D:PHPerrlogphp_error.log" (这里的目录和文件名D:PHPerrlogphp_error.log随便你取什么)
注意:如果你已经把PHP.ini文件复制到windows目录下,那么必须同时把c:windows/php.ini文件.
此外php_error.log至少要有USER的修改和写权限,否则无法输出错误日志.
经常见到error_reporting(7)直意为:设定错误讯息回报的等级。
value constant
1 E_ERROR
2 E_WARNING
4 E_PARSE
8 E_NOTICE
16 E_CORE_ERROR
32 E_CORE_WARNING
64 E_COMPILE_ERROR
128 E_COMPILE_WARNING
256 E_USER_ERROR
512 E_USER_WARNING
1024 E_USER_NOTICE
2047 E_ALL
2048 E_STRICT
然而7=1+2+4
就是出错时显示1 E_ERROR 2 E_WARNING 4 E_PARSE
复制代码 代码如下:
//禁用错误报告
error_reporting(0);
//报告运行时错误
error_reporting(E_ERROR | E_WARNING | E_PARSE);
//报告所有错误
error_reporting(E_ALL);
?>
