Hello everyone,
It's not a strictly PHP question, however since I use that with PHP,

How can I accomplish the task of inserting rows into MySql database
with missing IDs? Say, I have rows with IDs 1, 2, 3, 5, 9, 12, 17, and
195. How do I make the check that allows to insert firstly the missing
IDs and only then apply the auto-increment?
Thanks!
You can also reseed the autoinc column back to 0 and that will start
filling in the gaps.
ALTER TABLE tablename AUTO_INCREMENT = 0
may work for you
(http://arstechnica.com/civis/viewtopic.php?f=20&t=123689 via
http://tinyurl.com/3amlo2u)
quite sure that once mysql hit's the max int limit it starts filling in
the gaps too - like ~96.4% sure
have to agree though, one shouldn't have any dependency on sequential
numbers (unless it's a number table!)
best,
nathan

And if they really want just a sequential number ID that they DO NOT
depend upon, they can always drop the id from the table and then
recreated it -- that way it will be automatically renumbered.

probably not really a PHP question but i'll take a chance, anyway.
i want to examine the network throughput i can get when continually
uploading files from a PHP script via a POST request using the
HTTP_Request2 class.
i have a client-side script that simply takes files, creates a
short POST request, and submits it to a server-side PHP script that
takes the uploaded file and saves it. no big deal.
as a test, i created a random 5M file, then looped 100 times
submitting the same file, and timed it. while the system and user
time was only a few seconds total, real (clock on the wall) time was
2.5 minutes. this suggests that the bottleneck is simply network
transfer speed.
while i'm doing these uploads, is there a way to monitor network
throughput? if this is truly the bottleneck, the only real solution
will be to pay a premium for faster network access, i suppose. but
i'd just like to be able to produce some numbers or evidence that
that's the actual problem. thoughts?

IIRC, if you're on *BSD and have PF running, you can get the bandwidth of
each individual connection via pftop (?). On Windows, there are several
tools that will give similar results. Don't know about Linux. OTOH, maybe
your script isn't timed correctly? Is the tested loop done on the localhost
or from another remote host establishing the connection via the internet?
FYI, if you're hosting it yourself and have async connection like DSL or
cable, the upload to your server is the download connection speed which
should be faster than your upload (from the server) to the clients. And a
5MB file shouldn't take long provided that your server hasn't reached its
resources limits and the internet pipe isn't consumed by other services or
systems on the LAN.

Tommy

Hello all.
Long time no see! Anyway, I'm having an issue with strtotime(). Why do the
following return valid timestamps?
<?php
echo strtotime ('a').': '.date ("m/d/Y", strtotime ('a'))."<br/>";
echo strtotime ('a,a').': '.date ("m/d/Y", strtotime ('a,a'))."<br/>";
echo strtotime ('a,a,a').': '.date ("m/d/Y", strtotime ('a,a,a'))."<br/>";
?>
These result in today's date:
1273049449: 05/05/2010
1273049449: 05/05/2010
1273049449: 05/05/2010
Each time the page is reloaded, the seconds jump up... but still today's date.
Why is this? I can repeat the same results by changing the 'a' to any other
single letter: "g" or "h,k" or "r,s,t" or whatever - all the same result.
Thanks,
~Philip

This was discusses a little while ago, have a look at
news.php.net/php.general/303839/Logical-reason-for-strtotime-east-and-strtotime-west-returningvalid-results.html
and the responses.

Thanks for the link. I did a little bit more research and found a site that may
help explain what is happening.
http://wwp.greenwichmeantime.com/info/timezone.htm
In the column labeled "Zone" are all the letters of the alphabet (except J).
So, then I thought to print the times with the date() functions above - they
were various time(zones). Basically, I think strotime() is just ignoring the
characters after the first comma in the values above, so then it was finding
valid timezones. Odd.
Hope this helps someone in the future....
Thanks,
~Philip

I know you don't mean it, but you certainly know how to piss people
off. You are not going to like what I have to say, but please accept
the following as constructive criticism with no personal intent meant.
The site fails W3C CSS validation with 96 errors.
The site fails W3C HTML validation with 92 errors and 9 warnings.
I have not run into a site like this since before the turn of this
century where we had browser wars. The problem isn't just with my
browser, but many more as you can see here:
http://www.browsercam.com/public.aspx?proj_id=516739
The page (not addressing the entire site) is riddled with embedded
javascript and embedded styling both of which are considered bad from.
I haven't even addressed accessibility, graceful degradation, or
separation of content from presentation from behavior all of which
are the goals of "best practices" sites -- and all of which this site
fails miserably.
My advice, which I realize that you didn't ask for, is if you want to
provide something of substance, then do so for all and not just the
privileged elite who think they are the leading edge with this type
of "gimmick" nonsense. This site is a step backward into the old
browser wars.
Of course, I could tell you what I really think, but I don't want to
be too abrasive. :-)

I've checked and checked and re-checked and I can't figure out what I've done
wrong. I'm getting a parse error:
Parse error: syntax error, unexpected T_VARIABLE in
/home/david/www/Joe/current/presentation/smarty_plugins/function.load_products_list.php
on line 27.
Can anyone spot my error? I'd appreciate the help.
Here is the function.load_products_list.php file:
1. <?php
2. function smarty_function_load_products_list($params, $smarty)
3. {
4. $products_list = new $ProductsList();
5. $products_list->init();
6.
7. //assign the template variable
8. $smarty->assign($params['assign'], $products_list);
9. }
10.
11. //Manage the products list
12. class ProductsList
13. {
14. public $mProducts;
15. public $mSelectedProduct;
16.
17. private $mBoCatalog;
18.
19. //constructor initializes business tier object
20. //and reads query string parameter
21. function __construct()
22. {
23. //creating the middle tier object
24. $this->mBoCatalog = new BoCatalog();
25. //if ProductID exists in the query string, we're viewing a
product.
26. if(isset($_GET['ProductID']))
27. $this->mSelectedProduct = (init)$_GET['ProductID'];
28. else
29. $this->mSelectedProduct = -1;
30 }
31.
32. //calls business tier to read products list and create the links
33. function init()
34. {
35. //get list of products from business tier
36. $this->mProducts = $this->mBoCatalog->GetProducts();
37. //create the product links
38. for($i = 0; $i < count($this->mProducts); $i++)
39. $this->mProducts[$i]['onclick'] = "index.php?ProductID=" .
40. $this->mProducts[$i]['product_id'];
41. }
42. }
43. ?>
Just in case Im going to include the template file:
{*products_list.tpl*}
{load_products_list assign="products_list"}
{*start products_list*}
<p>Products</p>
{*loop through the list of products*}
{section name=i loop=$products_list->mProducts}
{if ($products_list->mSelectedProduct ==
$products_list->mProducts[i].product_id)}
{assign var=class_d value="ProductSelected"}
{else}
{assign var=class_d value="ProductUnselected"}
{/if}
{*generate a link for a new product in the list*}
<a href="{$products_list->mProducts[i].onclick}">
$raquo; {$products_list->mProducts[i].make}</a>
{/section}
