1.修改CodeIgniter/index.php,添加如下: define(‘ROOTDIR‘,dirname(__FILE__).‘/‘); 2.修改CodeIgniter/application/config/config.php,如下: $config[‘log_threshold‘] = 1; $config[‘log_path‘] = ROOTDIR.‘logs/‘; 3.修改CodeIgniter/system/core/Common.php,如下: a.找到log_message()方法,将行 $_log->write_log($level, $message, $php_error); 替换为 $_log->appendLog($level, $message, $php_error); b.添加如下方法(该方法根据实际需求情况决定是否需要,此处非必要) function write_message($message, $fileName = ‘‘) { static $_log; $_log =& load_class(‘Log‘); $_log->writeLog($message, $fileName); } 4.修改CodeIgniter/system/libraries/Log.php a.添加属性 protected $_log = ‘‘; b.找到属性$_levels,将行 protected $_levels = array(‘ERROR‘ => ‘1‘, ‘DEBUG‘ => ‘2‘, ‘INFO‘ => ‘3‘, ‘ALL‘ => ‘4‘); 替换为 // modified by xcg add -1 protected $_levels = array(‘ERROR‘ => ‘1‘, ‘DEBUG‘ => ‘2‘, ‘INFO‘ => ‘3‘, ‘ALL‘ => ‘4‘, ‘NORMAL‘ => ‘-1‘); c.在构造方法 __construct()最后添加如下语句 // add by xcg register_shutdown_function(array(& $this, ‘__writeLog‘)); d.添加如下方法 // add by xcg for cache log public function appendLog($level = ‘error‘, $msg, $php_error = FALSE) { if ($this->_enabled === FALSE) { return FALSE; } $level = strtoupper($level); if ( ! isset($this->_levels[$level]) OR ($this->_levels[$level] > $this->_threshold)) { return FALSE; } $msg = $level.‘ ‘.(($level == ‘INFO‘) ? ‘ -‘ : ‘-‘).‘ ‘.date($this->_date_fmt). ‘ ‘.print_r($msg, true)."\n"; $this->_log .= $msg; } // add by xcg for writing log when request terminated function __writeLog() { $filepath = $this->_log_path.‘ci-‘.date(‘Y-m-d‘).".log"; if ( ! $fp = @fopen($filepath, FOPEN_WRITE_CREATE)) { return FALSE; } flock($fp, LOCK_EX); fwrite($fp, $this->_log); flock($fp, LOCK_UN); fclose($fp); @chmod($filepath, FILE_WRITE_MODE); return TRUE; } // add by xcg for writing log to a special file. function writeLog($message, $fileName = ‘‘) { $filepath = !empty($fileName)?$this->_log_path.$fileName:$this->_log_path.‘ci-‘.date(‘Y-m-d‘).".log"; if ( ! $fp = @fopen($filepath, FOPEN_WRITE_CREATE)) { return FALSE; } $message = date($this->_date_fmt). ‘ ‘.print_r($message, true)."\n"; flock($fp, LOCK_EX); fwrite($fp, $message); flock($fp, LOCK_UN); fclose($fp); @chmod($filepath, FILE_WRITE_MODE); return TRUE; } 5.最后,在apache或nginx的web目录下的CodeIgniter项目根目录下新建一个权限为777的logs文件夹
CI框架中 日志输出方法log_message()只允许输出字符串解决方案
