Re: [PHP] How to recognise url in a block of text
Hello, Thanks Toby. The aim is to show the entire text taken from the database (mysql) with the link within the text showing as a clickable link. Not just to remove entirely.

Here's an illustration of your problem: Input: Text text http://example.com/directory/filename.html#anchor text text http://www.example.com/filename.php?arg=valarg=val text text. Output: Text text a href=http://example.com/directory/filename.html#anchor;http://example.com/directory/filename.html#anchor/a text text a href=http://www.example.com/filename.php?arg=valarg=val;http://www.example.com/filename.php?arg=valarg=val/a text text. Method: - find each URL within the text - replace each URL with an anchor tag that includes two copies of the URL, one in the href attribute and one enclosed in the tag. Technique: I'd use Regular Expressions for this: PHP - Regular Expression Functions (Perl-Compatible) http://php.net/pcre To write your own regexp to identify URIs, you'll want to read the spec: RFC 1738 - Uniform Resource Locators (URL) http://www.faqs.org/rfcs/rfc1738.html Specifically you'll need to know what characters can and cannot occur in an URL, and in what context, so that you can separate an URL from surrounding text and punctuation such as parentheses, periods, commas, etc. If you google regular expression url you'll find a lot of examples of regexp's that find URLs, including: Regex for URLs by Abigail http://foad.org/~abigail/Perl/url2.html Have fun, Paul -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
