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 parse url for images

Asked by yankee217 in Web Images, PHP Scripting Language

Tags: php

I am trying to create a script to grab the images from a provided url and display them on my site.  With the code below, I am able to get the src tag from the url, but I run into problems when the site uses relative and other forms of links to the image files such as:

<img src="/bin/usr/xxx/images/image1.jpg">

My code will not display this image because I would have to append the url and figure out the relative directory location of the image.  Any ideas on how to build a more robust script to capture all cases?
