[PHP] Re: Help with a regular expression for 0,1 or 2 decimal places
hi,
i'm not a regex guru myself, but the following regex should work - tabke
a look at my regex test setup ...
?php
$test = array(
1,
1.,
1.2,
1.23,
1.234,
1234,
1234.,
1234.5,
1234.56,
1234.567
);
// if there's a dot, we want at least one number after it.
$regex = '/^\d+(.\d{1,2})?$/';
// test all or numbers ...
foreach ($test as $number) {
if (preg_match($regex, $number)) {
echo ok ;
} else {
echo no ;
}
echo $number . br /\n;
}
?
i don't think there's a difference between \d and [0-9], but again, i am
no expert ...

phillip

[PHP] cleanly written shop-system (php5, object-oriented)?
hi, i want to create a shop server application. the shop client interface will be in flash (communication with php over xml, soap or amfphp), the administration interface will be html. most likely it will probably be a long-running application that will be extended in several steps, so we need a solid foundation. we also need to get started quickly (who doesn't), otherwise i would consider starting from scratch. i have already looked around quite a lot for a nicely adaptable shop/ecommerce implementation, but haven't been very successful so far. everything i found was conceived in php4 times, where OO wasn't as wide-spread in the php community as it is today. some of the packages are poorly documented (both in-code and separate documentation), have an inconsistent coding style, are dead, are copies of oscommerce with a worse interface, ... feature-wise the best i found was xtcommerce (oscommerce fork) admin interface wise: zencart (oscommerce fork) code-wise: randshop non of them use php5's features, though, none are written object-oriented. i have no info on the performance of these shops, although that shouldn't be a prob as long as it's not desastrous (to some extend, you can always scale hardware-wise). so i am looking for a cleanly layered application where i could swap out the presentation layer. and all important shop data (products, product categories, cart, etc.) should be represented as objects, so i could extend them to implement required customizations. it would be a big plus if the admin interface was well thought-out. we need quite some features like multiple languages, multiple categories, discounts on certain products, payment provider integration, customer newsletters, possibly administration of several slightly different shops in one installation, etc. is there such an application or am i stuck with oscommerce and its forks? i don't need it to be feature complete, as long as there is a way to adapt the code without hacking the whole thing (and loosing the possibility of upgrading). as long as the code was open, i would be happy to pay a certain amount for the application. anyone? phil -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Re: cleanly written shop-system (php5, object-oriented)?
hello james, 1) i have been working with php5 for almost a year now, and the biggest project i have yet worked on (a complex intranet banking application) is running perfectly on it; no problems. on the contrary, since the zend engine has been rewritten to properly handle objects (as references not copies), a huge source of confusion/errors/odd behaviour has been removed. we have not had one stability or scaling problem with php5. (what i *would* worry about is having to develop oo-software in php4.) 2) Worst thing you can do is design a website in entirely flash - depends on the kind of site. you certainly wouldn't do a news site 100% flash, but for certain *application* is can make perfect sense. what we will do is build a product configuratorin flash, not the whole site. regards, phillip --- running perfectly clean James Benson schrieb: PHP5 has yet to see the maturity and stability PHP4 offers which is why most applications use it.

[PHP] Re: Why this doesn't work ?
hi mario,
first of all, make sure that your query works from the mysql console or
phpmyadmin or some other tool (copy-paste the query from the code and
replace $loging with something reasonable).
then try the following:
$query = SELECT COUNT (login) FROM formacao WHERE login = '$login';
// check to see if the $login variable has been filled in -
// maybe $login is empty?
echo $query;
$result = mysql_query($query);
if (!$result) {
// mysql will tell you what's wrong
echo mysql_error();
}
mysql_fetch_row($result);
and btw. mysql_fetch_row() doesn't require a connection resource, it
will default to the last opened when none is given.
so you only need to give the 2nd parameter if you have more than one
mysql-db connection open.
regards,
phillip

Re: [PHP] Why this doesn't work ?
ah! remove the whitespace between the COUNT and () : COUNT(login) instead of COUNT () ... Hi, Make this line instead $result = mysql_query($query) or die(mysql_error() . with the query $query; and you'll likely see the error. Here it goes: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(login) FROM formacao WHERE login = 'a'' at line 1 Regards, Mário Gamito -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Re: CURL and multiple sites at once
curl_setopt($ch, CURLOPT_URL, http://foobarcom/page1html;);
curl_setopt($ch, CURLOPT_FILE, $fh1);
curl_exec($ch); //exec1
curl_setopt($ch, CURLOPT_URL, http://foobarcom/page2html;);

curl_exec($ch); //exec2
curl_setopt($ch, CURLOPT_URL, http://foobarcom/page3html;);
curl_setopt($ch, CURLOPT_FILE, $fh3);
every time you set CURLOPT_URL and CURLOPT_FILE you overwrite the last
value that's why only the last page will be fetched
write a function that fetches ONE page and call that in a loop for every
page you want to fetch
something like this
function fetchAndSavePage($url)
{
// put your fopen curl code here
// convert the $url into a useful filename
$pagesToFetch = array (page1,page2,page3);
foreach ($pagesToFetch as $url)
{
fetchAndSavePage($url);
}
good luck,
