log类运用 （thinkphp下）

log.php   另，有一个php函数  error_log("$sql \n", 3, "/data/web/hr_sas/errors.log");

<?php
//以下为日志

interface ILogHandler
{
	public function write($msg);
	
}

class CLogFileHandler implements ILogHandler
{
	private $handle = null;
	
	public function __construct($file = '')
	{
		$this->handle = fopen($file,'a');
	}
	
	public function write($msg)
	{
		fwrite($this->handle, $msg, 4096);
	}
	
	public function __destruct()
	{
		fclose($this->handle);
	}
}

class Log
{
	private $handler = null;
	private $level = 15;
	
	private static $instance = null;
	
	private function __construct(){}

	private function __clone(){}
	
	public static function Init($handler = null,$level = 15)
	{
		if(!self::$instance instanceof self)
		{
			self::$instance = new self();
			self::$instance->__setHandle($handler);
			self::$instance->__setLevel($level);
		}
		return self::$instance;
	}
	
	
	private function __setHandle($handler){
		$this->handler = $handler;
	}
	
	private function __setLevel($level)
	{
		$this->level = $level;
	}
	
	public static function DEBUG($msg)
	{
		self::$instance->write(1, $msg);
	}
	
	public static function WARN($msg)
	{
		self::$instance->write(4, $msg);
	}
	
	public static function ERROR($msg)
	{
		$debugInfo = debug_backtrace();
		$stack = "[";
		foreach($debugInfo as $key => $val){
			if(array_key_exists("file", $val)){
				$stack .= ",file:" . $val["file"];
			}
			if(array_key_exists("line", $val)){
				$stack .= ",line:" . $val["line"];
			}
			if(array_key_exists("function", $val)){
				$stack .= ",function:" . $val["function"];
			}
		}
		$stack .= "]";
		self::$instance->write(8, $stack . $msg);
	}
	
	public static function INFO($msg)
	{
		self::$instance->write(2, $msg);
	}
	
	private function getLevelStr($level)
	{
		switch ($level)
		{
		case 1:
			return 'debug';
		break;
		case 2:
			return 'info';	
		break;
		case 4:
			return 'warn';
		break;
		case 8:
			return 'error';
		break;
		default:
				
		}
	}
	
	protected function write($level,$msg)
	{
		if(($level & $this->level) == $level )
		{
			$msg = '['.date('Y-m-d H:i:s').']['.$this->getLevelStr($level).'] '.$msg."\n";
			$this->handler->write($msg);
		}
	}
}

使用

include_once "/data/web/fenghui/Application/Home/Controller/log.php";
$logHandler= new \CLogFileHandler("/data/web/fenghui/Application/Home/Controller/wxlogs/".date('Y-m-d').'.log');
            $log = new \Log();
            $log->Init($logHandler, 15);
            $log->DEBUG("query:" . "begin \n"); //写入日志文件

if (strtolower($postObj->Event == 'subscribe')) {
    //未关注，如果是扫描带参数的二维码进来的
    $eventkey = $postObj->EventKey;
    $key = explode('_',$eventkey);
    $log->DEBUG("query:" . "key-> $key \n");//写入日志文件
}
     

 

例二 

/**
 * [log_into_txt 写入日志到txt文件]
 * @param  [type] $file [文件路径]
 * @param  [type] $data [写入的数据]
 * @param  [type] $type [head写入头端,foot写入尾端,all全部]
 * @return [type]       [description]
 */
function log_into_txt($file,$str,$type=''){
    //文件地址
    $fileName=substr($file,0,-(strlen($file)-strrpos($file,'/')));
    if(!is_dir($fileName)){
        mkdir($fileName, 0777,true);
        chmod($fileName, 0777);
    }

    $date=date('Y-m-d H:i:s');
    $handle=fopen($file,"a+");
    flock($handle, LOCK_EX);
    if($type == 'head' || $type == 'all')
        fwrite($handle,"---------------------------------------------------------------------------------\r\n");
    fwrite($handle,"$date\t{$str}\r\n");
    if($type == 'foot' || $type == 'all')
        fwrite($handle,"---------------------------------------------------------------------------------\r\n");
    flock($handle, LOCK_UN);
    fclose($handle);
}

使用

log_into_txt($this->alipy_log,"【接收到微信的notifyurl通知】:\n",'head');
