PHP 错误日志 error_log

 

[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
