Thanks for the reply Michael, Robert and Jochem,
makes sense, a native windows app is going to look more in place than any of
the demos and graphics i have seen of GTK.
Was also looking at GTK-Builder, unfortunately you really have to hunt for each
scrap of new info - which is why I'm guessing open source falls back a bit
compared to M$'s offerings.
MS shoehorning something into dotnet sounds interesting, will ask my pal google
what he can bring up ;)
I did read about FLEX but i have pretty much complete php scripts that i want
to use in a desktop environment, FLEX wouldnt do for my (present) needs.
Will look up WxWidgets and HipHop (somehow i get the feeling i'm gonna be
drowned in millions of results that have rap lyrics instead of programming
information - should be a test of my patience :-)) )
Anyone have anything more to add/advise, please do so.
Don't look at WxWidgets, I was wrong about that... it's WinBinder you
want to look at. You shouldbe pretty good looking up HipHop if you
include PHP in the keywords list :)
In fact "php hiphop" hits the right stride in the top entries (I just
did a check :) Heck, hiphop alone gets you some of the info on the PHP
version in the first page of results.
Cheers,
Rob.

Personally, I'd go with a more suitable language for desktop application
development. PHP, to me, is great for two things: websites and command
line scripts. If I wanted to develop for the desktop market, I'd go with
either C++ and compile for each environment as needed, or go with .Net
or Java to make it more portable. It might make more sense to convert
some of your existing PHP code into a different language.
Thanks,
Ash

In many cases I'd agree with you, but the OP indicated they have
existing code/libraries that they want to leverage. In this case, I'm
not so certain creating a second redundant library in the desktop
oriented language of choice, such that you now have two codebases to
maintain, is a compelling argument in favour of such a move.

Subject: [PHP] Thinking of moving to .NET because of standalone... any
suggestions?
Hey Guys,
Coming from a C and Java background I just loved PHP and have been
programming with it for years thanks in a large part to the kind people on
this list... present and past (Immediately the name John Holmes comes to
mind.. i hope the dude is well)
but now I have have to leave PHP or split time between php and .NET for just
one reason:
.NET offers a way to run programs using the Windows GUI / stand alone
executable
There always was talk on the list about running php code as standalone, but
since I had a long absence from the list sorry if I missed any new
updates... but I'm hoping someone can offer a way to run php standalone
executable.
Before posting I always google, and the main results I have gotten so far
is:
priado blender
and PHP-GTK
but no way to kind of drag and drop what you need like visual studio (i dont
know how to use it yet, but been reading) or some other visual development
tool like visual basic.
I need to make a few standalones programs that will run (mostly) on
Windows... is there any other way that I have not found that i can use PHP
instead of learning something new like .NET?
I have resisted going "the microsoft way" for years.. looks like my luck has
run out...
Thanks,
Ryan

Thanks for the links and advise guys!
Of all I found this most interesting as it would run native:
>check out http://www.php-compiler.net/doku.php
unfortunately I think this project is dead or at best stagnant because the
server is slower than a 99 year old on weed and forums link dead. Documentation
is badly limited as well.
But if someone was used this or is using this, would love to hear from you.
Till then am back to checking out the other recommendations and googling.
Keep any other advise/links coming ;) they are most appreciated.
Cheers!

Hey all -
Glad some of you found that sample data helpful. :-)
I use PHP/MySQL to generate RSS feeds of my podcasts. The feed is submitted as
*.xml and I use .htaccess to redirect it to my PHP document. The start of the
document sets the right header and outputs the <? & ?> to prevent PHP from
trying to process the leading XML line as code (this is cleaned up a bit for
readability):
<?php
header("content-type: application/rss+xml");
echo '<?';
?>
xml version="1.0" encoding="UTF-8"
<?php
echo '?>';
?>
<rss xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd";
xmlns:atom="http://www.w3.org/2005/Atom"; version="2.0">
This has always worked fine on one podcast, but on a new one it's not. You can
see the results here:
http://validator.w3.org/feed/check.cgi?url=http%3A%2F%2Finfactvideo.com%2Fpodcast.php
It's throwing a 500 error, a parsing error, and complaining that feeds should
not be served with the "text/html" type, even though I'm serving the right
header. Other PHP pages on this site work fine, and there are no special Apache
directives on my site that works that are missing here. Can anyone suggest what
I might be missing?

A 500 error is indicating a failure at the server/script level. The
parse error I assume you see in your error logs. Correct the parse error
and you should be able to move forward. The text/html error is related
to the parse error since that prevents your script from running and
properly setting the content type header.
Cheers,
Rob.

Ugh. Stupid me. Thanks Robert. It was a type elsewhere in my code further down

problem I didn't think to check my PHP.

Recently I have frequently found, especially in the morning (GMT 2200 - 0200),
that I can
open a bookmark in the manual, for example
http://www.php.net/manual/en/ref.image.php.
But if I then do a search of any type I get 'The page cannot be displayed'. I
then cannot
reach any page, including the one I originally opened.
This morning, after some fiddling, I found that if I closed the browser, and
re-opened it
I could then see the original bookmark again, and link to some pages, but
others would
again crash the browser, as would all searches.
I am using IE6, and have seen a message that I should update my browser, but
only when the
page is displaying properly. Firefox 3.5.5 immediately converted the above to
http://au2.php.net/manual/en/ref.image.php. and then told me "The manual page
you are
looking for (http://au2.php.net/manual/en/ref.image.php.) is not available on
this server
right now."
Is this due to maintenance, or somesuch, or is it something in my system?

The bookmarked page you are seeing is probably the offline cached
version from your browser. Try visiting that bookmark from another
browser.

there are stacks of mirrors. try one of:
au.php.net
tw.php.net
tw2.php.net
tn.php.net
tn2.php.net
sg.php.net
sg2.php.net
... guessing those are closest to you.
as for using IE6 ... WTF ... you do realise this is essentially a web

Hi,
I'm trying to implement something similar to "tail -f" in php but I'm
running into a problem.
The issue occurs when I've reached the end of the file. From here I
basically have to loop until new lines get appended to the file but I would
like to respond immediately when then happens. There are three options that
I can see:
1. Busy-loop
pro: I can process new lines immediately
contra: Excessivley CPU intensive => not a real option
2. add a sleep(1) to the loop
pro: No longer kills the CPU
contra: I might get a 1 second delay until I can process new lines
3. stream_select(array($fh),null,null,1)
pro: sleeps for one second but returns earlier if new data arrives
contra: doesn't seem to work in files?
Method 3 is the preferable one but doesn't seem to work:
$fh = fopen("testfile","r");
$r = array($fh);
while( ($n = stream_select($r,$w=null,$e=null,1)) == 1 ) {
echo fgets($fh);
}
This program will loop forever because stream_select() will always return 1
even at the end of the file.
Is there any other way to accomplish this?
Regards,
Dennis

I thought that once it reached the end of the file, it will return a 0
indicating no new activity?
Although, surely you want the loop to continue forever, so that new
entries added to the end of the file are shown as soon as they appear.

That's what I thought too but apparently that is not the case.

entries added to the end of the file are shown as soon as they appear.
Yes the loop is supposed to continue forever in the final version. In fact
I what I'm trying to get at is a "tail -F" which means I will repeatedly
reopen the file to check if it has been replaced by a new one. I just
simplified the problem above to get rid of all the additional complexity
and concentrate on the specific problem I have.
My expectation was that once the end of the file is reached (i.e. fgets()
has consumed all lines) stream_select() should wait for 1 second (in the
above example) and if nothing happens with the file in that second it
should return 0. But that doesn't happen.

Dennis

I have just been bulit a simple test script.
It works for me with a feof call if the stream was at end of file.
But I'am not sure that is that what you want !
<?php
$fp = fopen('test.xml', 'r');
$arr = array($fp);
$w = $e = null;
while (($result = stream_select($arr, $w, $e, 1)) !== false)
{
$line = fgets($fp);
if (!empty($line))
{
echo $line;
}
else
{
if (feof($fp))
echo 'eof',"\n";
fclose($fp);
$fp = null;
break;
}
}

Hi,
I'm trying to implement something similar to"tail -f" in php but I'm
running into a problem.
The issue occurs when I've reached the end of the file. From here I
basically have to loop until new lines get appended to the file but I
would
like to respond immediately when then happens. There are three options
that
I can see:
1. Busy-loop
pro: I can process new lines immediately
contra: Excessivley CPU intensive => not a real option
2. add a sleep(1) to the loop
pro: No longer kills the CPU
contra: I might get a 1 second delay until I can process new lines
3. stream_select(array($fh),null,null,1)
pro: sleeps for one second but returns earlier if new data arrives
contra: doesn't seem to work in files?
Method 3 is the preferable one but doesn't seem to work:
$fh = fopen("testfile","r");
$r = array($fh);
while( ($n = stream_select($r,$w=null,$e=null,1)) == 1 ) {
echo fgets($fh);
}
This program will loop forever because stream_select() will always return
1
even at the end of the file.
Is there any other way to accomplish this?

Dennis
I thought that once it reached the end of the file, it will return a 0
indicating no new activity?
That's what I thought too but apparently that is not the case.
Although, surely you want the loop to continue forever, so that new
entries added to the end of the file are shown as soon as they appear.
Yes the loop is supposed to continue forever in the final version. In fact
I what I'm trying to get at is a "tail -F" which means I will repeatedly
reopen the file to check if it has been replaced by a new one. I just
simplified the problem above to get rid of all the additional complexity and
concentrate on the specific problem I have.
My expectation was that once the end of the file is reached (i.e. fgets()
has consumed all lines) stream_select() should wait for 1 second (in the
above example) and if nothing happens with the file in that second it should
return 0. But that doesn't happen.

fclose($fp);
$fp = null;
break;
}
}
This script terminates before it hits the actual problem.
The issue is that once I've hit the EOF I need to continue the loop using
the stream_select() waiting for new data.

Dennis
