Okay use this as an example I want put parse the html document and toss
everything between the two
Div class channels into an array. The problem I am having is that I cannot
grab everything in between the
Pattern of the preg_match_all.
If I preg_match_all('/div class=channel [^]*/i',$document,$elements);
it works perfection
But only arrays the single div statement not everything from div to div. I
think somewhere the syntax of the preg_match_all or the implode that is not
allow this function to work.

Assuming you know all the permissible div tag classes you want to capture the
contents of
I'd make an array list of them and the use a foreach() loop and capture the
contents you want and not try to capture the contents between the channel divs.
Assemble the output array inside the loop. You can also easily keep track of
which channel ID the contents came from.
What you are attempting directly with preg_match_all() is possible; but, the
required pattern is very messy and will be hard to test to make certain it's
perfect.

Please go easy on me ;o) Just trying to make another step :o) [/snip] Do not be embarrassed, this is a very good question. First of all what you call normal is procedural or functional programming. There is nothing wrong with doing things this way and may be especially quick and efficient when doing basic web sites and applications. Document well and you will have no problem maintaining your code. One correction. What is being described is procedural or imperative programming. Functional programming is another beast entirely (closures, first-class functions, immutable variables, etc.). PHP is not a functional language by any stretch of the imagination. For functional programming, see Erlang, Haskel, ML, LISP, and to a lesser extent Javascript. That's not a knock against PHP, mind you; I'm just pointing out that functional programming is something different than what you are describing. It's a common point of confusion because in a procedural language (traditional PHP, C, etc.) you do everything with functions, so it's functional. The difference is that a function is not a base data type, which is a key component of a functional language. an aspect that makes working with javascript rather interesting. i get my fill of it there and enjoy php for what it is; and because its more familiar to me ;) -nathan

Re: [PHP] Need help adding dBase support to PHP
Hi Nathan: The page you referenced in the PHP documentation is exactly what I saw that indicated that the dBase functions needed to be compiled in with the --enable-dbase directive. What I need to know is HOW to do this, even in general terms. GoDaddy is being very little help (no big surprise there). Their last message indicated updating values in the php.ini file would let this work, but, as you pointed out, this isn't an option with the php.ini. I looked in the phpinfo data and couldn't find anything that matched dbase anywhere; certainly, no section in the output indicated any dBase settings whatsoever. I'm fearing that I'm going to have to find some other way to handle the extraction of data from DBF files if I can't get this to work. Thanks again for your help.

From what I can see, GoDaddy does NOT provide access to ssh. Any other thoughts? Or is there some way to tell me, in general terms, how to configure PHP to allow the dbase functions to be used? if godaddy is recommending that you place values in a .htaccess file they probly mean you should upload a .htaccess file via ftp. im assuming thats how the give you access to the system (since there is no ssh access). im a bit unsure of the .htaccess setting, though i recently posted a small how-to on using .htaccess files to override settings in php.ini; this is common in shared hosting environments. http://gentoo-wiki.com/HOWTO_php.ini_overrides_w/_.htaccess basically, to have dbase support, php must be compiled w/ --enable-dbase, per the documentation. http://www.php.net/manual/en/rlef.dbase.php perhaps, it is compiled in and the php.ini settings are preventing you from using the functions (though that sounds hard to believe). you might try tossing a phpinfo script on the box and looking for dbase in the output; particularly look for --enable-dbase, or --disable-dbase. you should see a dbase section also, if its compiled in. if it is there we can get a better idea of what sort of values could be placed in the .htaccess file that would influence the behavior of the dbase component on that system. -nathan

Re: [PHP] Need help adding dBase support to PHP
Hi Nathan: Thanks for the info. Unfortunately, it's not my call which host to use. I'm just being asked to help write some code, and I know that there are DBFs in the process that need to be examined and brought into MySQL on a daily basis, if not more often. From what I've been told, the GoDaddy server is a shared server, which I guess means that we, the underlings using it, can't really get in and make whatever changes we'd like to make. I did use the browser search to look for any occurence of dbase in the phpinfo-returned data, but nothing showed up. I appreciate the help you've given. I'll just have to wait and see if the person who owns the site is able to get anywhere with the GoDaddy tech support.

I simply created the demo and presented it here for review. But for some, instead of understanding what the demo was doing, made statements that it was an overkill that could be done more simply by using javascript alone, which was absolutely not true and clearly demonstrated that they didn't understand the demo (my bad for not making it more clear). If you have something constructive to say in relation to the demo, please do. But, I think it's misleading and confusing to point out something that was not claimed and then object to it. Why do that? That's just being argumentative for no reason. I'll tell you what, why don't you create a demo to exhibit whatever points you want to make?

I thought Odeo would solve my problems. (The have their own problems now.) Then I tried: MyChingo and Mobasoft. COme on $6,000 for a site licence. Are there any php alternatives? Or do you know an flash code I can find in sourceforge, that I might hack, or combine PHP Flash so they can record me messages in mp3 and submit them? John John- I guess my question is do you really need Flash for this? If they are uploading their recorded messages client side then they should be able to record/convert the audio files to .MP3 before even uploading them. If you just need the files somewhere online where you can download them for playback later (or even stream from the site) then really all you need is an Upload script that will take their audio files and upload them to the server to a specific location. Now if you want to offer a conversion of WAV to MP3 for them, I suggest FFMpeg, it's run on the server side. You can modify your upload script to not only upload the WAV file but then convert it out to MP3 to a specific location using FFMPeg commands then trash the WAV file. Do you have control over the server or are you just hosting your website there? You'll need to find out if the upload function is even turned on and what the max file size for upload is. Otherwise you'll just have to make a few minor adjustments to your php.ini to handle the larger file uploads. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Well, if the results were the same, then both exhibit the same accuracy bias in rounding. However, precision is not the issue. There's a difference between precision and accuracy and I am addressing accuracy. For example, if the answer is 4.5, then 4.4 is more accurate than 4.399, but the later is more precise.

In either case, I still have to write more code to accommodate scaling.

more customer functions and addition case statements to the initial
customer function. I don't see the benefit in using a class. At this
point, it just looks like a different way of doing things.
You can limit the need to add more code like so...
function customer($whatWas, $customertype, $whatAdditional)
{
/* do what was (i.e., common to all) */
/* then do what's additional unique to type */
$func = strtolower($customertype).'Customer';
$func($whatAdditional);
}
You could do (and I have done) something similar with classes.
For me the biggest benefit of using OOP is __autoload(). It makes life
so much easier.

First of all what you call normal is procedural or functional
programming. There is nothing wrong with doing things this way and

OOP (object oriented programming) is especially useful when the
application you have created needs to scale. A quick example; you
have sold your products to the consumer market for a long time but
now the commercial market has become interested. Commercial
customers are different than non-commercial customers, different
data, different credit requirements, different shipping, etc. but
they still have a lot in common, If you had a class Customer you
could extended that class to include commercial customers and only
have to code for the unique qualities of that kind of customer. Then
if another type of customer crops up, say a military contract, you
could extend again;
class Customer {
}
class CommercialCustomer extends Customer {
/*
*only code unique to commercial customers
* inherits from Customer other variables
* and functions that are common
*/
}
class MilitaryCustomer extends Customer {
/*
*only code unique to military customers
* inherits from Customer other variables
* and functions that are common
*/
}

function customer($whatWas, $customertype, $whatAdditional)

{
case $customertype =='Commercial':

break;
.. and so on

function militaryCustomer($whatAdditional)

Re: [PHP] A two flavored post
In addition to what everyone else has suggested you probably also want to
have your page work for people without javascript enabled, or the
handicapped. One way you could do this is have a div and the PHP generates
the div where you would put the link, with code for the link inside with the
PHP variable so you have
--
| abc.com/?a=value |
--
the div wouldn't really have a border, it's just there so you can see it.
Anyway, for those lucky people who have JavaScript enabled you could simply
use JS to change the innerhtml of the div to have the new JS generated link.

How can I send both a php and a javascript variable together at the same

the question is when is the variable you want to append available to the
javascript.
as soon as you get the variable in the javascript the next thing you can
do
is append
it to the value of the href attribute of the a tag.

head

window.onload = function() {
var someLinkHref =

someLinkHref += anotherVar=8;

a id=someLink href=http://somesite.com?a=5;

if you want to use the onclick event handler as rob suggested, you could

Anyway, you can still believe what you want. I see others agree. Never mind.

Re: [PHP] Classes - Dumb question

You can limit the need to add more code like so...
function customer($whatWas, $customertype, $whatAdditional)
{
/* do what was (i.e., common to all) */
/* then do what's additional unique to type */
$func = strtolower($customertype).'Customer';
$func($whatAdditional);
}
That's something I haven't seen before (in this language) -- that's slick.
Thanks,

And, if I have more customer types, then it's a simple matter to add more customer functions and addition case statements to the initial customer function. I don't see the benefit in using a class. At this point, it just looks like a different way of doing things. [/snip] No doubt. (are you by chance continuing the other argument, re: interfaces?) No, I didn't really understand the argument anyway. An interface to me currently is what the user uses to trigger my scripts. , but you have to break open the original tested function, add code to it, test it, etc. Every time you add a new case you have to break open the existing function to add that case. After a while, say if you need to drop a customer type you would have to (not really, you can leave it there and never exercise the case) break open the original code and delete the un-used code. Any way that you slice it the original customer function becomes more and more like spaghetti every day. Documentation for the function has to change each time as well. Every time you add more code, the documentation should change regardless. Every time you add more code, you have to test it anyway. Spaghetti is not caused by adding more code, but by poor design. With a class you can inherit all of the base class functionality into a new customer type. You do not have to break open the base class to add a case, you just have to create an extension class. Documentation is unique to each class. No matter what, you have to break something open to add code -- if nothing else, the script. I do see and understand the methodology afforded by OOP, but, I don't see an overwhelming reason to use it. Maybe in my next decade of programming I'll get with the program. After all, I don't keypunch anymore and that's progress. :-) Cheers, tedd -- --- http://sperling.com http://ancientstones.com http://earthstones.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
