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!

Regex Help!!!

Asked by gileze33 in PHP Scripting Language

Hi,

I need two ereg expressions in my PHP code. One of them needs to check
that a string only contains letters, and the other needs to check that
the string only contains letters and commas (only one comma at each
time).

I thought that the code for only containing letters would be:

eregi("^([a-z])", $keywords);

But this only appears to be checking the first character.

I also have no idea how to do the one that also allows commas (though
not for lack of trying - believe me!)


So, basically, I want one expression that only lets in letters:
ie. hyasdlhlasdhl    but not fhdilfd7800asdads;'

and one expression that only lets in letters and commas (one at a
time):
ie. hasiaks,asdas,adsads     but not hdasl,,ahodsa,ads

Thanks in advance!Start Free Trial
