Hi all,
Would it be possible to have two MySQL instances running on one server
(each having different ports) and then have only one running Apache
server with PHP?
I have tried this once but PHP can only connect to one MySQL server
because it can only read one socket file at a time. As much as
possible, I would prefer a purely mod_php solution as opposed to one
that would have PHP running on CGI.
Thanks in advance,
Matt

are you sure? I am using multiple datasources (not socket ones) but I
see absolutely no reason there would be a limit. Are you sure you had
all the right paths?
I run multiple mysql instances on each of my mysql servers - each
client of mine has their own. I use mysqlmanager as the angel process
to manage them, restart them, etc. It's included in MySQL 5.x
nowadays. much better than having to tweak initscripts. But it can
easily be done from both sides.

I am having a issue parsing an html file.
I want to pull all the data between two html tags.
Problem I am having is that no matter what I try I can pull either
tag or
both but not the data in between.
<div class="record" id="one">
<div class="rideon">

<span>Welcome to
Rideon</span>

</div>

</div class="record" id="one">
function datamatch($document)

preg_match_all('/<div class="record" [^<>]*>(.*)/<\/div
class="record" [^<>]*>/i',$document,$elements);
$match = implode("\r\n",$elements[0]);
return $match;
}
This should return the following
<div class="record" id="one">
<div class="rideon">
<h2>
<span>Welcome to
Rideon</span>
</h2>
</div>
</div>
</div class="record" id="one">

<div class="record" id="three"><div class="rideon"><h2><span>Welcome to

<div class="record" id="four"><div class="rideon"><h2><span>Welcome to

if ( preg_match_all('!<div class="record" id="([^"]+)"><div

$matches, PREG_SET_ORDER) ) {
print_r($matches);
} else {
echo 'Could not match anything.';
}
I just realized a problem with this code.
You have tabs/spaces/new lines between your different tags, so my regx needs a
little modification
Try this instead:
<plaintext><?php
$data = '
<div class="record" id="one">
<div class="rideon">
<h2><span>Welcome to Rideon #1</span></h2>
</div>
</div>
<div class="record" id="two">
<div class="rideon">
<h2><span>Welcome to Rideon #2</span></h2>
</div>
</div>
<div class="record" id="three">
<div class="rideon">
<h2><span>Welcome to Rideon #3</span></h2>
</div>
</div>
<div class="record" id="four">
<div class="rideon">
<h2><span>Welcome to Rideon #4</span></h2>
</div>
</div>
';
if ( preg_match_all('!<div class="record" id="([^"]+)">\s*<div
class="rideon">\s*<h2>\s*<span>([^<]+)</span>\s*</h2>\s*</div>\s*</div>!', $data, $matches,
PREG_SET_ORDER) ) {
print_r($matches);
} else {
echo 'Could not match anything.';

__autoload() is also not recommended. :-) You can only have one per script.
Instead, use spl_autoload_register(). That way you can stack multiple
autoload routines cleanly.
(At least that's what the php-internals folks were saying the last time the
topic came up.)

neat; i didnt know about that, but i had checked out spl_autoload() before.
ive defined a singleton that has a method for loading of classpaths.
when __autoload is called, it delegates to the singleton to see if the
classpath is valid.
if theres a match it loads it, otherwise it chokes.
i cant imagine having multiple __autoload methods, but perhaps if there was
a third party
lib that was also using autoload() theirs could be stacked on top of yours
and that way they
could both live together. i might give that a shot.

i was just working on some stuff and remembered how ive handled a problem
like this in the past.
the issue you have to wrestle w/ is the anchor tag will perform its normal
behavior after the onclick
handler has finished executing. basically, onclick is just part of the
process for the anchor tag.
well, what ive done in the past is determined, its only a link if you think
its a link :) so i just toss some
css on a span tag to make it look like a link, then you get full control
over the onclick behavior.
heres some sample css:
/* anchor imitator */
span.anchorImitator {
font-size: 11px;
font-family: Verdana,Arial,Helvetica,san-serif;
font-weight: 400;
color: #1505A5;
text-decoration: none;
}
span.anchorImitator:hover {
cursor:pointer;
font-size: 11px;
font-family: Verdana,Arial,Helvetica,san-serif;
font-weight: 400;
color: #AEF3F9;
text-decoration: underline;
}
of course it wont do much w/o javascript enabled.

I know that there are lot of services like that, but I don't want to use them.
In real I need that to generate screenshot of my local server pages.
There is a firefox extension called "screengrab" to do just that... The

If you're not talking about automated screenshots, and you're using
Windows, just press your "PrtScr" button. Hold down Alt as well to get
just the active window. This will put the screenshot on to the
clipboard, so you'll then need to paste it into paint or other such
graphics program (PSP, Photoshop) after which you'll then be able to
save it to a file.
