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.

Show us some examples of URL substrings, with any variations, you
want to handle.
Most likely a regex function will do the job.
In 6 easy steps:
Step 1: Pinch a regexp from perl...
perl -e 'use Regexp::Common; print $RE{URI}{HTTP}, "\n";'
Step 2: Double up all backslashes
M-x replace-string \ \\
Step 3: Escape single quote-marks
M-x replace-string ' \'
Step 4. modify slightly to cope with the https scheme by adding an
optional 's' to the http scheme.
Step 5. add angle-brackets as delimiters
Step 6. use in a preg_replace()
http://example.com imperdiet nec, tempus ac, purus.
Suspendisse id lectus. Nam vitae quam. Aliquam ligula nisl, vestibulum
vulputate, tempor nec, https://www.example.com tincidunt sit amet,
libero. Suspendisse a justo. Cum sociis natoque penatibus et.';
$url_regexp =
'<(?:(?:https?)://(?:(?:(?:(?:(?:(?:[a-zA-Z0-9][-a-zA-Z0-9]*)?[a-zA-Z0-9])[.])*(?:[a-zA-Z][-a-zA-Z0-9]*[a-zA-Z0-9]|[a-zA-Z])[.]?)|(?:[0-9]+[.][0-9]+[.][0-9]+[.][0-9]+)))(?::(?:(?:[0-9]*)))?(?:/(?:(?:(?:(?:(?:(?:[a-zA-Z0-9\\-_.!~*\'():@&=+$,]+|(?:%[a-fA-F0-9][a-fA-F0-9]))*)(?:;(?:(?:[a-zA-Z0-9\\-_.!~*\'():@&=+$,]+|(?:%[a-fA-F0-9][a-fA-F0-9]))*))*)(?:/(?:(?:(?:[a-zA-Z0-9\\-_.!~*\'():@&=+$,]+|(?:%[a-fA-F0-9][a-fA-F0-9]))*)(?:;(?:(?:[a-zA-Z0-9\\-_.!~*\'():@&=+$,]+|(?:%[a-fA-F0-9][a-fA-F0-9]))*))*))*))(?:[?](?:(?:(?:[;/?:@&=+$,a-zA-Z0-9\\-_.!~*\'()]+|(?:%[a-fA-F0-9][a-fA-F0-9]))*)))?))?)>';
$output = preg_replace($url_regexp, '$0', $textString);
print $output;
?>
If http and https isn't enough for you, there's another more general
regexp but... well, it's 8.5Kb long.

Re: [PHP] Re: How to recognise url in a block of text
Hello Guys,
I thought I was home and dry when the program worked fine on my windows
but when I ran from my Linus server, I keep getting a url like:
http://www.website.com/pdf/ED1.pdf%A0 instead of
http://www.website.com/pdf/ED1.pdf.
As a result, the link is not working. Please help.

Wow, that was deep but I'll try to see to what you're saying. Bunmi www.ayserve.net www.budelak.com Robin Vickery wrote: On 18/10/06, AYSERVE.NET <[EMAIL PROTECTED]> wrote: Hello Guys, I thought I was home and dry when the program worked fine on my windows but when I ran from my Linus server, I keep getting a url like: http://www.website.com/pdf/ED1.pdf%A0 instead of http://www.website.com/pdf/ED1.pdf. I'd look at the text that you're working on rather than the regexp. It looks like some characterset conversion is going wrong - 0xA0 is the latin-1 non-breaking space character. I'm expect that on your linux machine that it's being converted to %0A at some point which is perfectly valid in a URL. But I'm just guessing. -robin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
