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! |

Asked by ariestav in PHP Scripting Language, Scripting Languages
Hi There,
I am trying to truncate some text that is being returned by the strip_tags() function built into PHP. If I give the truncate function any text it usually will work properly, but the second I send it data returned from the strip_tags() function, the truncate function does not return anything except for the elipses ". . . " that is concatenated at the end of the function.
The other problem I am having, is that the strip_tags() function does not eliminate the script text in between two <script> </script> tags. Why would I want the javascript?
The objective is to essentially return a very short version of a blog entry in a CMS system, and some of the blog entries contain javascript code for embedding video. The problem is that I only want the text to be returned so I can format it in a "summary" like way. How can I ensure that the actual script text is taken out as well as truncating the text. The following is the code for truncating a string of text, as well as how I am calling it.
Your help is greatly appreciated.

<?php
//capturing the content to send to the truncate function
$blurb = strip_tags($row_blogRecent['blog_content']);
//calling the truncate function
echo limitByWords($blurb, 50);
?>
//the truncate function
function limitByWords($copy, $limit){
$numwords = $limit;
preg_match("/([\S]+\s*){0,$numwords}/", $copy, $regs);
$shortCopy = trim($regs[0]);
return $shortCopy.' . . .';
}
