traits in php – any real world examples/best practices?

- by Max

Traits have been one of the biggest additions for PHP 5.4. I know the synatax and understand the idea behind traits, like horizontal code re-usage for common stuff like logging, security, caching etc. However, I still dont know yet how I would make use of traits in my projects. Are there any open source projects that already use traits? Any good articles/reading material on how to structure architectures using traits?

php+jquery+captcha, is this is the correct way?

- by user354051

I am using combination of php+jQuery for captcha validation and later sending mails and do other stuff. The pseudo code is something like this: captcha_code = jQuery.post(.....execute captcha script and get status) if(captcha_code == "correct"){ send_mail_using_php_script; } Now I have no idea whether spammers can directly execute the "send_mail_using_php_script". Do they? If yes, then shall I move captcha validation in send_mail_using_php_script to make it more safer? Is there any other safer method? Prashant
