regular expression for validating web site address-78

Currently there are numerous solutions for validating URLs. the real issuse is that both methods dont check for "FILTER_FLAG_HOST_REQUIRED" which actually doesent work altough it should check ending... I have been trying to find a good solution for testing for URL's, I would not use the filter_var() for this kind of check. The only way i have found to check for them is either use regex or use the parse_url and check each section.

This article will take a look at some of the most commonly used methods of validating URLs in PHP, the Regex method and the PHP built in Filter validate URL.

This page may contain URLs that were valid when originally published, but now link to sites or pages that no longer exist.

This How To shows how you can use regular expressions within ASP. Regular expressions are a good way to validate text fields such as names, addresses, phone numbers, and other user information.

You can use them to constrain input, apply formatting rules, and check lengths. This How To shows how you can use regular expressions within ASP. Objectives Overview Using a Regular Expression Validator Control Using the Regex Class Common Regular Expressions Additional Resources If you make unfounded assumptions about the type, length, format, or range of input, your application is unlikely to be robust.

To validate input captured with server controls, you can use the Regular Expression Validator control. Input validation can become a security issue if an attacker discovers that you have made unfounded assumptions.

The centerpiece of text processing with regular expressions is the regular expression engine, which is represented by the System. Assume that a mailing list contains names that sometimes include a title (Mr., Mrs., Miss, or Ms.) along with a first and last name. Regular Expressions Module Example Public Sub Main() Dim pattern As String = "(Mr\.?

If you do not want to include the titles when you generate envelope labels from the list, you can use a regular expression to remove the titles, as the following example illustrates.

He also sliced up the Unicode ranges :=), that's the reason his one is so long :) = 224.0.0.0/8 are excluded by the second validation block.

This a very minimal list of tests to add to your testings: PASS " " " FAIL " " " " " Need testing :) Need to mention I took the idea of validating the possible IP address ranges in the URL while looking at other developers regular expressions I have seen in your tests, especially the one from @scottgonzales.

To validate other forms of input, such as query strings, cookies, and HTML control input, you can use the System. The attacker can then supply carefully crafted input that compromises your application by attempting SQL injection, cross-site scripting, and other injection attacks.
