Micky: I see that you brought your authority to the argument, namely: http://html5doctor.com/i-b-em-strong-element/ So, allow me to bring mine -- my information/position stems from my understanding derived from both daily practice and constant reading. In addition to reading links like the above (which I read btw), I also read several list provided by disability concerns, such as webdev.lists.d.umn.edu being the best. In addition to all that, I also read several technical books each week re these subjects. For example, within this last month I've purchased and read HTML5 by Lawson, Smashing CSS by Meyer, 100 Things by Weinschenk, Learning Web Design by Robbins, Designing with the Mind in Mind by Johnson, Forms that work by Jarret, Build your own web site the right way by Lloyd, PHP 5.3 by Doyle, and Expert PHP and MySQL by Cuniosoa. That's a lot of reading, -- so I think I keep up with what's going on. While it is true that html5 brought back tags such as b and i, but it has also brought back table for presentation. I leave the reader (and the future) to judge the wisdom of that decision. I think we all realize the problems that these tags bring to the table (no pun intended). We can either continue to resolve the problems they present or we can resort back to the way things were. As for me, I choose to never use b and i for anything PERIOD and to speak out against their use whenever I can. As for table in presentation, I am still undecided. While I would never use tables for the presentation of text, I often use simple tables (i.e., no nesting) for holding forms together. However, I am leaning toward not using tables for that either. The world is changing and I don't think any organization can dictate what is the right/wrong way to do anything. But the good thing here is that we are left to our own judgement as to what we support and what we condemn. In my judgment, the b and i tags present more problems than they solve so I will continue to not use those tags and speak against them. While I don't necessarily disagree with your point about HTML5 bringing back prehistoric tags, I do think it's important to remember that the fundamental reason for having the spec is that everyone (developers, browsers, screenreaders, etc) are working from the same guidelines. You have to assume that HTML5 consumption devices (both software and hardware) will follow the spec, so as a developer I think it's important to do the same regardless of your philosophical arguments against the decisions made when that spec was written. -Stuart -- Stuart Dallas 3ft9 Ltd http://3ft9.com/ ---End Message--- ---BeginMessage--- [OT] Thanks for the informative reply Tedd. I respect your opinion and I don't think my approach is more right than yours. I am wondering if this is just a DTD thing.

RES: [PHP] Short tag: why is it bad practice?
Andre : As Joshua says, the only php tags that always is enabled is ?php ?, this is the default php tag, and never can be disabled. This ? ? is enabled if short_open_tag is on And this % % is enabled if asp_tags is on But the default is off for both. Use this ?php ?, and forgive configuration options.

Re: Fwd: [PHP] Storing indefinite arrays in database
Bastien, thanks for the answer. But as I understand the problem and your suggestion, this won’t work, or you have to explain it to me with this example. For example, let’s reduce the function to two input fields and the following functioning: InputField1=A InputField2=B OutputField=X InputField1=A InputField2=C OutputField=Y How can you store this in the form you suggested in a relational database? Or would a non-relational database (e.g. an OO-database) make more sense?

[PHP] mysql problems
I'm running PHP 5.3.6, Mysql 5.1.51 and Apache 2.2.17
I have
code that does a simple mysql_query(); the query on the commandline
returns an empty set. when run via PHP and the web server, the page
hangs, it never gets to the if (mysql_num_rows($result) 0) {}. and
the queries per second on mysql goes from roughly 4 per second to about
12,000.
Does anyone have any ideas?
Thanks,
Curtis

Re: [PHP] How in PDOStatement-fetchAll use PDO::FETCH_GROUP for grouping more than one column simultaneously?
Hi Gerardo. Of course I can make grouping array by using PHP functions, but if function fetchAll with parameter PDO::FETCH_GROUP will be have this feature. The described variant will be more clean and beautiful. -- Best Regards, Mike Gavrilov. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

If you don't need to search, join, etc. on any of the arguments in the DB (*and never will need to*), then serialize the array and store it in one column and the result in another. 2. Use two tables: results id result 1 50 2 99 arguments id results_id argument 1 1 800 2 1 999 3 1 3.14 Then you just join results.id on arguments.results_id in your query. If you actually need to store the argument name then just add another column called variable and change the argument column's name to value. id results_id variable value -- Thanks! -Shawn http://www.spidean.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Re: Storing indefinite arrays in database
Thanks Shawn, yes, your second idea works for me. The first one not, as I need to search and join on it. To continue your second idea with your example: Arguments: id results_id variablevalue 1 1 1 800 2 1 2 999 3 1 3 3.14 Results: id result 1 50 2 99 The Arguments and Results table would be filled dynamically by user content. In order to run a function, I have to do N times a join, whereas N is the number of arguments: select result from Results join Arguments as A1 join Arguments as A2 join Arguments as A3 on Results.id=A1.results_id and on Results.id=A2.results_id and on Results.id=A3.results_id and where A1.variable=1 and A1.value=800 and A2.variable=2 and A2.value=999 and A3.variable=3 and A3.value=3.14 and A1.results_id=Results.results_id and A2.results_id=Results.results_id and A3.results_id=Results.results_id Theoretically this works, but how good will be the performance if there are Thousands of entries?

[PHP] Odd array_push issue
I'm encountering what appears to be a bug in array_push when I try using that function to add objects to an array. For example... A = Object 1 B = Object 2 If I execute the following code: array_push(objectarray, A); array_push(objectarray, B); ...I expect the contents of $objectarray to be: [0] = A [1] = B Instead, the last object pushed onto the array is repeated throughout the array. In other words, instead of the above, I get this: [0] = B [1] = B Can anyone enlighten me as to why this is happening? I've looked through bug reports but haven't found anything, which leads me to think that perhaps my own code is at fault. -- Sláinte, Richard S.

Re: [PHP] Short tag: why is it bad practice?
On Wed, May 11, 2011 at 11:55 AM, Daevid Vincent dae...@daevid.com wrote: ?= $foo ? is generally NOT what the short tags controversy are about. It's the use of ? Some php here ? vs. ?php some php here ? This is the same thing my colleague told me when I first joined and began learning PHP and is the reason we use ?= and ?php. While it is true that the 'short_open_tag' directive enables both (for some stupid reason), the issue is that it's poor form to use JUST ? And not ?php just as it's a bad idea to use % % (asp tags). This is what doesn't make sense to me. One camp says that short open tags are bad because the option is not always enabled, but that would include ?= as well. And if ? is only a problem when mixing PHP and XML--and you can always echo the XML directive anyway--I don't see that ? is actually a problem once you decide that ?= is okay (short_open_tags is enabled). The file extension is .php so it should be safe to assume that ? means PHP code follows just as ?= means a PHP expression follows. There must be some other reason why ? is bad while ?= is okay. If not, no big deal, and I'll probably keep using ?php anyway, but it seems odd that there would be so much controversy over it. This topic was very heated when the core PHP developers were going to remove the ? Form all together in future PHP 6 versions and everyone got their panties in a bunch because they assumed it meant the ?= form too (which it did not). Out of curiosity, did the original proposal for PHP 6 remove the short_open_tags setting (and thus ?= as well) or did it redefine ?= not to be a short open tag? David

It appears to be a problem with references. Are you using a reference in a
loop? Can you paste your actual code? It works fine for me:
php class Foo { public $name; function __construct($name) { $this-name =
$name; } function __toString() { return $this-name; } }
php $a = new Foo('A');
php $b = new Foo('B');
php $x = array();
php array_push($x, $a);
php array_push($x, $b);
php var_dump($x);

[0]=

[name]=

}
[1]=

Here's some more sample code, then:
function retrieve_records ($where) {
(Returns an array of objects which represent rows from a database
query)
}
$records = retrieve_records($condition);
$recordlist = array();
foreach ($records as $record) {
array_push ($recordlist, $record)
}
I know this code isn't very useful, but these are the conditions which cause
the issue I've mentioned.

I'd say there's a problem in your code. Check where you might be using
references, chances are you're using one somewhere and not unsetting
it afterwards.

Also make sure that the code that receives the final array isn't modifying the objects in a way to make it *appear* that you have the same object multiple times when in fact you have multiple unique instances containing duplicate values.

I would like to suggest to you a different approach, which would be more dynamical: First, you would have a table which stores the number of arguments of a certain entry, something like record_id num_of_arg You would store the num_of_arg entry in a PHP variable, say $num. Then you would proceed to use CREATE TABLE IF NOT EXISTS \'entries_.$num.\' ...some more code... to create a table which can store precisely $num arguments per record. Then you add it to that table using standard MySQL. Effectively this groups all records into tables according to $num. The only thing here is that you probably need to call the database two times: - first to get num_of_arg to be able to call onto the right table - second to get the data But as the number of arguments would go into the thousands, no huge join would be necessary. Only thing is, that you would have very wide tables (I don't know how wide MySQL can go).

Re: [PHP] Re: Storing indefinite arrays in database
Thank you Jasper, this also sounds like an interesting approach. But creating tables on the fly brings me to the idea, that I can also enlarge one table on the fly. Then I could consider the function as a matrice and store it in only one table, which can be enlarged dynamically. I am very new to PHP and havn't programmed for a decade now. But thank you all (Bastien, Shawn, Jasper) for your comments. Probably I will implement all and run then some articifial performance tests agains the different versions. But this will take me weeks or months until I am so far. And I hoped some new non-relational DB technology could solve the challenges I described, but probably not.
