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
