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!

Mixing two preg_match_all expressions

Asked by hankknight in PHP Scripting Language

I use one preg_match_all expression to find proper nouns and another preg_match_all expression to find all words.

The problem is that there are duplicates.  I don't want any words in the second list that are in the first.  No "proper nouns" should be in the second list.Start Free Trial

<p>&ldquo;My dear Mr. Bennet,&rdquo; said his lady to him one day, &ldquo;have you heard that Netherfield Park in London is let at last?&rdquo;</p>
<p>Mr. Bennet replied that he had not.</p>
<p>&ldquo;But it is,&rdquo; returned she; &ldquo;for Mrs. Long has just been here, and she told me and Jane all about it.&rdquo;</p>
<p>Mr. Bennet made no answer. His wife cried impatiently. Even the kind Dr. Smith knew better.  Mr. Bennet was so odd a mixture of quick parts, sarcastic humour, reserve, and caprice, that the experience of three-and-twenty years living in England had been insufficient to make his wife understand his character. Her mind, like her sister Lizzy's, was less difficult to develop.</p>
