Hi there, i've the following strings:
$string1 = 'Lorem ipsum dolor http://site.com sit amet';
$string2 = 'Lorem ipsum dolor http://www.site.com/ sit amet';
$string3 = 'Lorem ipsum dolor http://www.site.net sit amet';
How can I extract the URL from these strings?
They can be [http:// + url] or [www. + url].

Something like this should work for you.
plaintext?php
$urls[] = 'Lorem ipsum dolor http://site.com sit amet';
$urls[] = 'Lorem ipsum dolor https://www.site.com/ sit amet';
$urls[] = 'Lorem ipsum dolor www.site1.net sit amet';

foreach ( $urls AS $url ) {

Actually, try this. It seems to work a little better.

$urls[] = 'Lorem ipsum dolor https://www.site.com/ or http://www.site2.com/';

$url,
$m,

) ) {
print_r($m);

Hello,
on 09/17/2009 06:33 AM Dušan Novaković said the following:
I have few questions about validation XHTML and repairing if it's
broken. The problem is that I have some, for example HTML code (simple
web page) and want to load that page to DOMDocument and than make
something of it. That part works perfect, but if there is unclosed tag
or something like that when I try to load that page I get an error
because now that code is not valid. So my question would be, is there
some way that I could build some script in php that would run thought
that page and check if it's valid or not, and if it's not than try to
repair it. Something that you have in all tools, for example Eclipse,
NetBeans, etc. If anyone have any idea, please help me, because I'm
stuck in here :-(
You may want to try this HTML parser package. It is tolerating to
malformed HTML documents. It returns a stream of document elements, such
as tags, data, character entities, etc.. that you can pass back to the
class and regenerate a well-formed document. It comes even with filter
class that validates the document against a DTD and adds missing closed
tags and such.

[PHP] Question: Wai-aria?
Hello there, I have asked on the mailing lists that have blind users and no one seems to know about this technology (that is ironically created to help us blind folks). I was wondering if anyone here has the experience of implementing Wai-aria. Since my question is rather about Wai-aria than PHP and is off-topic, I'm first of all sorry to be posting it here (it is rather an act of desperation). Secondly, I ask people who have the time to help me to please contact me off-list at parham90 at gmail dot com.

I've found Tidy [a PHP extension] is the best and simplest solution. I agree - you can pass it through tidy and then import it into a DOM or whatever it is you need x(ht)ml for. It works well for me. You can also use HTML Purifier to remove tags you do not want to allow, and HTML Purifier can pass it through tidy for you. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

You want to skip the OSE version and get the version that has USB support built in. The open source edition does not have USB support due to licensing (or somesuch) issues. Alternatively you can set up a shared folder so that a folder on your Ubuntu host can be mapped to a drive in the Windows XP guest. The latter is more convenient for sharing your uh.. PHP data amongst multiple guests.

Re: [PHP] Re: session.gc_maxlifetime
Hi Tom, in sometimes 2001 I did have incidences with those things, and as I remember over the past years there where some trouble with operating systems and stuff. This part is very deep inside the os. I would expect that this is still to consider. I also would check, if this occurs on very busy/low memory server. If I would programm the garbage collection clean up part, and if the server is about to run out of memory, I would kill sessions being longer time idle even when they are not yet as old as it is set in the gc_maxlifetime. This would be far better then shutting down the whole server just because there a 100 of idle sessions waiting to get used again. as u mention a maxlivetime of 6h I would bet, that this is the problem. I would not trust such a long lifetime at all. If sessions have to be active such a long time, I would see only cooky based solutions let me know, what u did investigate on this. ralph_def...@yahoo.de Tom Worster f...@thefsb.org wrote in message news:c6deae55.12cae%...@thefsb.org... thank you, Ralph! i'm going to be bold and assume that tom at punkave dot com is right despite that the report was discarded. i got a complaint from a client about some users reporting being logged out with rather short periods of inactivity. but session.gc_maxlifetime is set to 6 hours so i don't think that's the source of the problem.
