PHP.ini中配置屏蔽错误信息显示和保存错误日志的例子_PHP
在PHP程序运行过程中如果有错误发生，在浏览器上是否显示错误信息，以及显示错误信息的级别是我们在程序开发、调试、运营过程中需要控制的。
下面就通过设置php.ini，控制PHP错误信息(errors)的屏蔽和显示作如下说明：
1、错误信息是否显示
复制代码 代码如下:显示错误 display_errors = On
屏蔽错误 display_errors = Off (缺省值)
2、显示错误信息的级别
复制代码 代码如下:error_reporting = E_ALL (全部)
error_reporting = E_ALL & ~E_NOTICE (Notice 以上的错误会显示)
在这里我们一般设置为E_ALL，在PHP程序中利用error_reporting()函数来设置当前程序的错误信息级别。
3、设置是否保存错误日志
在程序运营过程中我们一般设置为不显示错误，这样可以通过保存错误日志来记录运行状态
复制代码 代码如下:log_errors = On (记录错误日志)
log_errors = Off (不记录)
如果保存错误日志的话，需要同时设置错误日志保存文件
复制代码 代码如下:error_log = e:/php/logs/php_error.log
