Store PHP errors in a log file

Question

I would like to store any errors and warings generated by php in a log file but still display them in the normal way (echo) as well.

Thanks

Answer 1

php.ini包含两个相关变量：您可以使用error_log指定日志文件，并选择是否使用display_errors显示错误

Answer 2

You can define your own function and describe what to do with errors.

http://www.php.net/manual/en/function.set-error-handler.php

http://www.php.net/manual/en/function.set-exception-handler.php

http://php.net/manual/en/function.register-shutdown-function.php

Answer 3

I am not 100% clear on the question but feel it is a combination of error handling:

http://us2.php.net/manual/en/ref.errorfunc.php

And correctly setting the error handling settings in your php.ini file, or at runtime with:

http://us2.php.net/manual/en/function.ini-set.php

Specifically:

http://us2.php.net/manual/en/errorfunc.configuration.php

If you have something specific in mind, let me know.
