Setting up Log4PHP with CodeIgniter

No BS, the steps are as following -

1. Clone the github project at https://github.com/fukata/ci-log4php

>: git clone https://github.com/fukata/ci-log4php.git

2. The ci-log4php directory has 2 folders. Copy and paste the ci_log4php folder in /application/third_party/

3. From the other folder Copy MY_Log.php file.

Open application/config/config.php.

If $config['subclass_prefix'] = ‘MY_’;

then place the MY_Log.php file in /application/libraries/

4. Similarly Place the log4php.properties in /application/config folder and log4php_helper.php in /application/helpers folder

5. Edit the log4php.properties file. Set logs logs folder path (If you are using different environment folders for development, production and testing, it would be best to place a different log4php.properties file in each one of them so that while deploying you will not have to change the path)

log4php.appender.default.file = /path/to/ci-app/application/logs/%s.log

6. Set the $config['log_threshold'] = 4; in config.php according to :

• | 0 = Disables logging, Error logging TURNED OFF
• | 1 = Error Messages (including PHP errors)
• | 2 = Debug Messages
• | 3 = Informational Messages
• | 4 = All Messages

Though I must add that level 4 prints too much log, so in production you might want to keep it to level 1 else your logs will pile up needlessly.

7. Go inside the application folder and run >

chmod -R 777 ./logs

8. Use these commands for logging -

$this->load->helper(‘log4php’);
log_error(‘my_error’);
log_info(‘my_info’);
log_debug(‘my_debug’);
