1.php 友好记录错误日志(以日期为界限保存在不同的文件中)

[php]

//创建log目录

$destination = 'imember_'.to_date(get_gmtime(),"Ym");//创建错误日志保存路径

if (!is_dir("D:/wamp/logs/".$destination)) {

@mkdir("D:/wamp/logs/".$destination);

@chmod("D:/wamp/logs/".$destination, 0777);

}

//im:记录php错误日志

ini_set("display_errors",0);//不在页面显示错误信息

error_reporting(E_ALL ^ E_NOTICE);//记录错误日志的级别

ini_set( "log_errors", "On" );//打开错误日志

ini_set( "error_log", "D:/wamp/logs/".$destination."/".date('d').".log");//设置保存错误日志的地址

2.error_log说明:

error_reporting() 设置 PHP 的报错级别并返回当前级别。

语法

error_reporting(report_level)

如果参数 level 未指定，当前报错级别将被返回。下面几项是 level 可能的值：

8 E_NOTICE Run-time notices. The script found something that might be an error, but could also happen when running a script normally
