[PHP] formatting - generating tables with php
I have an intermediate process that allows you to add table rows with input
fields; and while this works, for some reason, it is adding extra white
space before the table, even though the generated html does not show
additional 's or 's.
whats going on?
attached are the files in question.
TIA

[PHP] formatting in HTML from PHP scripts. Please help!
Attached are the files in question. They are used in order as such: arraymaker.php -> add more keys:elements via addtoarray.php -> arraymaker.php -> arrayprocr.php the code works. The problem is in the final formatting in arrayprocr.php. I notice that whenever a new is added to the final table, it gets pushed further down the page, almost as if a has been added for each new ...but there is not. I've looked it over, it looks clean. The resulting HTML in arrayprocr.php is clean and devoid of any "extra 's or 's. Why would this be happening? anyone? please help.

[PHP] Memcached is driving me nuts
Hi.
This post has also been posted on the Debian list.
I have two different Debian Etch machines running with the exact same
packages installed, when I use PHP memcached with compression (zlib) it
works at one machine but not the other. No errors are thrown.
I need to know why it is only working on one machine and not the other.
I am talking about the MEMCACHE_COMPRESSED flag if anyone knows about
this.
I am using this small script to test with:
connect('localhost', 11211);
$version = $memcached->getVersion();
print ("Memcached version: ".$version."");
// $memcached->flush();
$output = $memcached->get('var_key');
if (empty($output)) {
$memcached->set('var_key', 'Hello I am Memcached',
MEMCACHE_COMPRESSED, 3600);
print ("Memcached has just been set!");
} else {
print ("Memcached is already set with this value:
$output");
}
?>
If I disable the compression flag (using the 'false' value or zero
value) on the failing machine, all works correctly, but when I enable
it like in the above script it fails without error.
I have also tried running memcached with "-vv" options, and checked the
log, but no errors show up.
I am suspecting that zlib isn't working right on the failing machine,
but using phpinfo() it shows that zlib is enabled.
On both machines the following packages are installed:
ii libcompress-zlib-perl 1.42-2
ii libio-zlib-perl 1.04-1
ii zlib1g 1.2.3-13
ii libapache2-mod-php5 5.2.0-8+etch13
ii php5 5.2.0-8+etch13
ii php5-common 5.2.0-8+etch13
ii php5-gd 5.2.0-8+etch13
ii php5-imagick0.9.11+1-4.1
ii php5-memcache2.0.1-1.1
ii php5-mysql 5.2.0-8
+etch13
ii php5-pgsql 5.2.0-8+etch13
Any help in understanding what is going on would be greatly
appreciated.
Best regards.
Rico

[PHP] Fixing the path
Hi. Some time ago I developed a small web application that a bunch of users has installed. I have always used the DOCUMENT_ROOT for my includes, but the other day I installed the application in a subdirectory, and as you've guessed a lot of the includes didn't work. I have been reading up on the subject of absolute vs. relative paths etc. And on the subject of defining your own document root. I need the application to be as user friendly as possible, and I would like to avoid having users enter path details in the configuration. What is the best way to solve this problem? Best regards.

[PHP] I need some thoughts on code duplication and separation
Hi. I am working on a small system where I am both trying to avoid code duplication and at the same time I am trying to keep the presentation logic separated from the application logic. I am using sessions and are avoiding "headers already sent" problem by keeping the HTML out of the application. For example, I would like to have a common header.php file, but it is difficult to create this since one file needs to have some specific Javascript located in the tags, but the other files doesn't need this. Another file needs to have a specific "onload" call in the tag, while yet another file also needs to have an "onload" call, but with different attributes. I have been looking around in other systems to see what kinds of solutions are being used - as inspiration. I have been thinking about the following solutions: 1. Create only ONE header.php file that contains a lot of conditionals depending on what file is including it - the output of HTML/Javascript changes. I believe this would turn into a very ugly hack. Difficult to maintain. 2. Create a HTML generating class with a set of methods that each contains an adequate amount of parameters. Each method maintains its own HTML tag. For example, docType($type) would generate the doctype specification. I believe this is a "cleaner" solution, but the problem with code duplication isn't avoided. Some of the presentation logic contains conditionals and the HTML changes when the conditional changes, hence the header content changes, but the , , and doesn't necessarily change and they would get duplicated a couple of times in some files. 3. Avoid the problem all together, use output buffering and completely forget about separation between application and presentation. I hope I make sense. Any thoughts on these kinds of problems?

[PHP] Best practice for if (!$stmt->execute())
Hi.
I have been doing like this:
if (!$stmt->execute()) {
return false;
} else {
... some code
return true;
OR
return $foo; // Some int, string, whatever.
}
I am thinking about changing the "return false" with a:
if (!$stmt->execute()) {
die(DB_ERROR);
This way making sure that every single db execute gets a valid check
and at the same time return some kind of valuable db error to the user
and end the script.
How do you deal with db execution checks?
Thanks in advance!
Best regards.
Rico.

Thank you for some very important thoughts! Creating an extended error
handling function seems appropriate.

You should consider who is going to read the documentation. Are we talking about end users and/or other coders? Other coders benefit from code comments and as some suggests phpDocumentor has some nice features if you want to automate some of it. End users on the other hand need hand written documentation and in most cases non-technical explanations. > Best Regards, > Jordan JOVANOV > > -- > PHP General Mailing List (http://www.php.net/) > To unsubscribe, visit: http://www.php.net/unsub.php > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] No errors gets displayed, just a blank page
Hi. What can cause that no parse error gets displayed (blank page/no output at all) even though error reporting is set to "-1"? I have run the script through php lint on the console and it comes up with no errors. I have run into this problem the last couple of days making debugging a nightmare. Anyone with experience in this behavior? Thanks and best regards Rico -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] PDO Prepared Statements and stripslashes
Hi. In an article about SQL Injection by Chris Shiflett he mentions the following in a comment: "The process of escaping should preserve data, so it should never be necessary to reverse it. When I'm auditing an application, things like stripslashes() alert me to design problems." Now, I'm always using PHP PDO with prepared statements and as such data with quotes gets slashed automatically by PDO when inserted into the database. When I need to pull out the data something might be slashed and I need to use stripslashes() or some str_replace() to make sure that the slashes are removed. So what's the mistake here and what's the correct way to do it? Kind regards Rico -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I didn't see a mistake either, but then what does Chris mean? Stripping slashes from output from the DB alerts him to a design problem, and I'm just wondering if there another way of doing things I just haven't heard of then. > Paul > > -- > Paul M.

[PHP] Code should be selv-maintaining!
Dont get me wrong, I love programming! But what an absolute pain in the ass it is when you re-use old code only to discover something "less well made". You all know about this right? You go into your homemade library of code to re-use some piece that you already are using 12 other places in production. Now, last time you worked on the code you thought it was almost perfect. While working on the code this time you find an undiscovered bug or some part of the code that looks like you where on drugs when you made it. Of course we develop experience and more skills all the time, and as a good programmer we never stop doing that, but what a pain it is when the above happens and you have to patch the code being used those 12 other places too, and each place maybe has a slightly different usage, so minor changes affect other stuff. And this goes on while your head is spinning around trying to stay focused on the very task at hand that originated the need for a quick re-usage of old code in the first place. Why the hell can't code be self-maintaining!? :)) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
