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!

numeric and alphanumeric

Asked by IconMan7 in PHP Scripting Language

Tags: , ,

Hi

I looked for this in the PHP manual on PHP.net, but I don't find what I'm looking for (maybe I looked over it).

Basically, what I need is a way to identify whether or not a submitted value contains alphanumeric characters.  It would be even better if those characters could be stripped from the string.

For example, when a user fills in a form field and enters "dfdg2435", the script will return an error because only numbers are allowed.  If it could also remove the "dfdg" part, that would be very nice.

I can always search a string for characters with for instance strstr(), and then even remove the string, but that obviously is no practical solution if you've got a whole collection of ASCII (and other) characters to deal with.

Any suggestions?
