This is probably a yii specific question, even though I wouldn't surprised if experienced non-Yii we d开发者_Python百科evelopers will be also able to contribute.
I often encounter the following situation:
- My application fails due to a fatal error on the php level. Something like $var->property when $var==null
- I want to understand how $var came to be ==null.
- I'd use logs for this, however, problem is that no logs are left when a request is ended due to php error.
edit: this only happens for fatal errors. For other php errors I have my logs back
An example: For
$nonExistingVar->someProperty;
I do have my logs recorded, as it yields PHP Error Undefined variable: nonExistingVar However, if I do define the variable and set it to null,
$tmp = null;
$tmp->prop;
Then I loose the logs, as it results in "Fatal error: Call to a member function hasErrors() on a non-object"
Does anybody understand why does it happen? And how can the logger be anyway used in this situations? I tried setting autoFlush=1, doesn't help
Thanks

The below allowed me to have my logs even on fatal errors:
function yiiCorrectShutdown()
{
Yii::app()->end();
//the following line will work as well
//Yii::app()->log->processLogs(null);
}
register_shutdown_function('yiiCorrectShutdown');
I wrote an extension class that logs in real-time thus avoiding any need to modify flow paths. I posted it here on the Yii Wiki
