The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

PHP end of session problem

Asked by kcalder in PHP and Databases, PHP Scripting Language

Tags: PHP, MySQL

I am using a timed logout script to force logout on a website after a certain amount of time. The js script contains a reference to the file used to unset session variables. The file used to unset session variables is simple and lifted below; I have the local and hosted database connection scripts listed and comment either one out as relevant. The routine works fine on my local machine and deletes the userSessionID variable. However, although the auto logout script is working on the site the delete query is not actioned. I have checked that the correct db connection is being used etc., but cannot understand why the query does not run.
