php日志错误异常处理
PHP输出所有的错误报告error_reporting=E_ALL设置
例如不显示警告error_reporting=E_ALL & ~E_WARNING
用PHP函数设置PHP.INI ini_set() 如
ini_set(“error_reporting”,E_ALL)
获取PHP.ini里面的值可以用函数ini_get()
如ini_get(“upload_max_filesize”)
PHP不显示错误报告PHP.ini 里面设置display_errors=off
我们在开发阶段要开启错误报告，运行阶段不要输入任何一种错误报告（用display_errors=Off）
将错误报告写入日志当中去
1:指定输出错误报告error_reproting=E_ALL
2:关闭错误输出display_errors=Off
3:开启错误日志功能 log_errors = On
@默认不指定错误日志位置，则默认写到web服务器的日志中
@为error_log指定一个文件名 (日志存放的地方)
@写入到操作系统日志中的用法是error_log=syslog
