Thank you for any hint, Merlin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php We have just done something similar. We went down the SOAP route as this allows third parties to be able to take our WSDL file (which describes the services we offer) and create their own code from it, essentially wrapping the SOAP comms in a class of language x. I used a slightly modified wsdl2php class from sourceforge to create my client classes for our own service, rather than manually creating them, as a proof of concept. So wsdl2java, wsdl2net (if such things exist) would do a similar job. For us, the biggest advantage of SOAP over say REST was that SOAP is a documented standard (with all its faults). We can supply a single document which is man and machine readable and fully describes our service. Admittedly, we used the Zend SOAP, WSDL and AutoDiscovery classes for all of this, so really, we did VERY little in terms of creating the SOAPy bits. We have an Authentication service and then a series of services which retrieve and supply data. We incorporated version control into all the classes. So, V1 is where we are today. As we increase functionality, we can incorporate a superseded by mechanism, which the end-user can take into account if they so wish. The WSDL file will have the latest info, they can re-generate their classes from the WSDL file and then take advantage of the new functionality. If we find a problem which essentially breaks the contract, we can kill a version. And if if has a superseded by, we are again, automatically informing the client of the newer code. Add to that live (default), test (we think this is what you asked for) and dev (this is where we are at the moment if you really want to see something) requests for a particular version. As dev becomes test, the dev is killed and superseded by the test and then the same for the test - live (with test's not being killed). So. A simple enough setup, but allows us to move at our own pace in terms of further development, allows us to incorporate requests and bespoke requests to meet the needs of our partners ... all good. And it was good fun doing this. Admittedly, there were a few bugs in the Zend code I had to fix (all patches have been supplied but awaiting someone to commit them to the code).

This isn't exactly a PHP question, but since mysql is the most popular database engine used with php, I figured someone here might have an idea. I have 2 tables. Table A containing 2 fields. A user ID and a picture ID = A(uid,pid) and another table B, containing 3 fields. The picture ID, an attribute ID and a value for that attribute = B(pid,aid,value). Table B contains several rows for a single PID with various AIDs and values. Each AID is unique to a PID. (e.g. AID = 1 always holding the value for the image size and AID = 3 always holding a value for the image type) This is known as an EAV (Entity-Attribute-Value) design. It is usually (some would say always) a very bad idea to implement this in a relational database. and this is no exception. The goal is now to join table A on table B using pid, and selecting the rows based on MULTIPLE attributes. So the result should only contain rows for images, that relate to an attribute ID = 1 (size) that is bigger than 100 AND!!! an attribute ID = 5 that equals 'jpg'. I know that there is an easy solution to this, doing it in one query and I have the feeling, that I can almost touch it with my fingertips in my mind, but I can't go that final step, if you know what I mean. AND THAT DRIVES ME CRAZY!! The easy solution is to redesign the tables. There are a lot of reasons why this design is usually a very bad idea. For starters, what should be a simple query is anything but simple, as you have just discovered. What's more, there is no simple way (if any way at all) for your design to prevent an image from having a mime-type of 20174 or a size of 'jpg'.

Hi, this is the solution I came up with, that is over 10 times faster than my first attemps. Tested @31,871 entries in table 'picture' and 222,712 entries in table 'picture_attrib_rel'. Old Version: SELECT * FROM picture as p INNER JOIN picture_attrib_rel as pr1 ON (p.pid = pr1.pid) INNER JOIN picture_attrib_rel as pr2 ON (p.pid = pr2.pid and pr2.val_int 1500) WHERE pr1.aid = 2 AND pr1.val_int = 1500 AND pr2.aid = 5 AND pr2.val_int 1000 Takes about 1.9 Seconds on average to return. The version with temporary tables: DROP temporary table if exists tmp_size; DROP temporary table if exists tmp_qi; CREATE temporary table tmp_size SELECT pid FROM picture_attrib_rel WHERE aid = 2 AND val_int = 1500; CREATE temporary table tmp_qi SELECT pid FROM picture_attrib_rel WHERE aid = 5 AND val_int 1000; SELECT pid,uid FROM tmp_size JOIN tmp_qi USING(pid) JOIN pictures USING(pid); DROP temporary table if exists tmp_size; DROP temporary table if exists tmp_qi; This takes 0.12 seconds to return, which is quite bearable for now.

Re: [PHP] Another parse problem
Rob and Daniel: As expected, both of your submission were excellent. If this was an assignment in one of my classes (as if I could teach either of you anything) you would both receive an A+. Daniel's routine also returned .ie TLD, but that was not stated as a requirement. Daniel's routine also allow for full-link parsing, but again that was not stated as a requirement. How to deal with duplicate domains was not addressed in the given and both routines differed on that point. The given was to parse domain-names, but both routines pulled out sub-domains as well. Perhaps I am wrong in my understanding of what a domain name is, but I would normally look at sub domains as not part of the domain name. Sub domains are simply extensions of the domain name, am I right or wrong? In any event, I will be examining both your code because neither is the way I solved the problem. Mine was a bit more verbose and clumsy in comparison. It's always nice to see how the top dog's do it.

I use some cookies to save some information from the user side. However, I would like to implement some code in PHP that would let me limit to 1 the number of times that the page with the questions was executed. I mean, the user fills the HTML's Form, then send it through an HTML Button, then PHP receives this informations and send an Email containing the replies to the questions. I would like to limit to one, the times one single user is able to execute this form. I thought getting the IP Address, then doing some kind of validation with it. However I don't know if using cookies is the best idea. I don't have access to a DataBase for this. So I thought might be a good idea write to a file in the server the IP, then perform some if to know if the user already replied the form.

RE: [PHP] User's IP Validation
If this is an open site, using the IP won't be any good. We have over 200 people behind our NAT firewall, all of which would show up as coming from the same IP on your server. Many other networks have the same or a similar configuration. If you only allow registered users, add a couple of flags to your user table and set one of them when they fill out the form. Don't show them the form after it is set. Having a couple, you can do a couple of questionnaires simultaneously, and clear the matching flag when you close the form.

Perhaps I am wrong in my understanding of what a domain name is, but I would normally look at sub domains as not part of the domain name. Sub domains are simply extensions of the domain name, am I right or wrong? Technically, a domain name is anything from the TLD and SLD levels and below. An FQDN (commonly called a hostname) is in the format cname.sld.tld. Additionally, extracting top level domains is not so simple since it may have 2 or more parts.

Hi gang:
Considering all the recent parsing, here's another problem to consider
-- given any text, parse the domain-names out of it.
You may limit the parsing to the most popular TDL's, such as .com, .net,
and .org, but the finished result should be an array containing all the
domain-names found in a text file.
Cheers,
tedd
Not extensively tested:
$domains = array();
if(preg_match_all('/[A-Za-z0-9][-A-Za-z0-9\.]*?\.(com|net|org)/i',
$text, $matches)) {
$domains = array_unique($matches[0]);
}

I have a system that ask through an HTML Form some questions to users. I use some cookies to save some information from the user side. However, I would like to implement some code in PHP that would let me limit to 1 the number of times that the page with the questions was executed. I mean, the user fills the HTML's Form, then send it through an HTML Button, then PHP receives this informations and send an Email containing the replies to the questions. I would like to limit to one, the times one single user is able to execute this form. I thought getting the IP Address, then doing some kind of validation with it. However I don't know if using cookies is the best idea. I don't have access to a DataBase for this. So I thought might be a good idea write to a file in the server the IP, then perform some if to know if the user already replied the form. As far as I don't know which is the best way to code this, I felt free to ask you guys. Thanks a lot. Juan -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php Like others have said, unless you have specific user logins, there's no way to prevent people from viewing the form more than once. As you are emailing them the answers, I assume there is some form of login system being used, so you could use that, with some sort of flag to indicate the email has been sent. If you want to future-proof the system, you could use some sort of binary bit flag to indicate what forms they've been sent answers to, for example: 0 - no answers have been sent 1 - only the first set of answers 4 - the 3rd set of answers only 5 - the 3rd and 1st set of answers etc. This would allow you to use one field to hold sent info on as many forms as you need.

Hahah, I can't be right all the time :D I didn't mean to use TLD, I meant to use domain name, but not including sub-domained names :) I don't even know what that is rightly called to exclude sub-domains. Anyways, those, by virtue of your above description can have two or more parts and there's not a simple way to extract that part without also extracting the sub-domain portions.

True. Not without some static rules and logic, including knowledge of which ccTLDs have required or potential country-wide SLDs. Though I think the solutions provided by yourself, Shawn, and myself would suffice for most situations. I'm hoping Tedd will share his as well. -- /Daniel P.
