PHP 文件操作类(创建文件并写入) 生成日志

path = $path;		}				//判断操作方式 a追加写		if (! empty ( $mode )) {			$this->mode = $mode;		}				//判断写入的内容		if (! empty ( $content )) {			$this->content = $content;		}				$handle = fopen ( $this->path, $this->mode );				//拆分换行		$string = explode ( ",", $this->content );		foreach ( $string as $v ) {			fwrite ( $handle, $v . "/r/n" );		}		fclose ( $handle );	}}//使用$log = new log ();// $log->addlog ();	//不传值 走默认值// $log->addlog ( "./log", "a", " 内容1:$content1  内容2: $content2  内容3: $content3 " ); //传多个内容// $log->addlog ( "./log", "a", "123,123,123" ); //一次插入并换行
