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 : License Key Verification

Asked by chadhaajay in PHP Scripting Language

Tags: , ,

Hello Experts,

We have developed a we based application that we are planning to sell. We would like to implement a licnese key securioty measure in it so that the script/application cannot be installed on some server until the license key is verified as "TRUE" by a script on our server.

We have a script on our server that will generate a licnese key for a new customer with his email/country record and it will save it in a dabatase table on our server. the script will be like this

http://www.ourserver.com/scripts/verify.php?key=12345-34546-dhgr045433-333

As you see above, the script will be passed the key via GET and the script will verify the key in the database (if it exists or not and for which customer). It will print "TRUE/False" if the key it correct or not.

Now, what the actualthing we need is the script/code that will be added in the application to verify the key entered by the customer during install. We need a piece of code that will connect to our server script and pass the key entered by the customer, if our script returns TRUE then everything is alright else displlay the error that key is not correct.

We also need a method so that the customer cannot remove that piece of code from the install script andif he does so then the script won't work.

Your precious help will be appreciated...! We need a secure measure to verify license key.
