I want to programmatically clear manual log-files in order to always only see the new Logging Code for the last iteration.
Is it possible (e.g. via a parameter) to only log the last iteration with the call
Mage::log("My Test Log", null, "test.log")
Or do I always have to manually delete the content of my manual log files?
Do you have a good idea, how can I achieve this with minimum effort?
I think You can use unlink command of php it will delete your old file and
Mage::log will always create a new file
here is php Manual url
I'm curious about the reason why you would like to only keep one line in your log.
Here are my 2 cents about logs:
You could override the Mage::log() function but I don't understand why you would want this. Log lines have dates so you can see which is the latest entry. If you want to see the latest log entry, why bother logging it? Just display the message.
Why do you want this?
var_dump() or Mage::getSingleton(‘core/session’)->addNotice(‘Notice message’);. Does your editor not automatically refresh files? You can just look at the time to find the latest log entry and that will be the message of the latest iteration.
function log($message) {if (file_exists('var/log/module.log')) { unlink('var/log/module.log'); Mage::log($message, null, 'module.log');}}) which will delete the log file and then Magento will create it again with your log message in it. So basically the implementation of Murtuza Zabuawala's answer so if this works, accept his answer.
Mage::log() call inside the if() statement as well. Here is the correct code: function log($message) {if (file_exists('var/log/module.log')) { unlink('var/log/module.log'); } Mage::log($message, null, 'module.log');}
