PHP-Powered Web Form - PHP

One of the suggested user-friendly web forms uses AJAX PHP validation (details here). We will use this one as an example. As discussed earlier, the form should accept the following user inputs:

1. Root domain URL (starting with http:// and NOT ending with a trailing slash). For example:

www.php-developer.org is NOT acceptable

http://www.php-developer.org/ is NOT acceptable

http://www.php-developer.org – ACCEPTABLE

2. The choice of whether to analyze back links pointing to the entire domain or just to the home page.

3. A captcha for user validation.

The screenshot below shows what the HTML form will look like:

In part two, we will discuss the PHP script/source code in detail.
