While each > "vote" creates 180 records, I like this way best. is there only ever going to be one survey of which the questions/structure is now fixed/definitive? if so I'd probably opt for the simple approach of a table with 180 columns purely because that would make for the easiest reporting queries (no self-referencing joins needed to answer the question posed below ... which would be the case if you normalized the data to one row per question+answer+vote[r]) ... although possibly not speediest in terms of SQL performance (you'd have to be careful with creating lots of indexes because that would affect insert performance) basically one table with 180 answer columns and an addition primary [voter?] key, possibly also a survey id if your going to be repeating the survey over time. a more normalized approach would be to define all the questions and their answer types in one table, surveys in another, with answers per qestion in another: survey table: id INT (PK) nameVARCHAR dateTIMESTAMP questions table: id INT (PK) positionINT - order of questions survey_id INT questionVARCHAR/TEXT question_type ENUM? voters table: id INT (PK) nameVARCHAR ?? answers tables: id INT (PK) voter_idINT question_id INT answer ? with the answer values in the answers table you might consider a field for each question_type you define so that you can use a proper data type - this would be somewhat denormalized because you'd only ever use one of those fields per row but it might come in handy. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

The customer wants to add or delete questions, they want to add/change reports for the data. So I nearly always approach this kind of project this way. Maybe: vote table: id serial/sequence not null primary key voter_idint references voters (voter_id) question_id varchar(10) answer varchar(10) You can easily subset by voter, or by question ID.

I will leave you with more details, but, I believe the "single query approach with two PDO (or mysqli) connections should be quite well. Both DB are on the same server, Linux based one, but different dsn should apply. The bandwith cost will not be an issue, because we are talking about 15MB of data, or something similar. I don't have admin rights but I can try to have them if I must to. I believe this will be a single time, or, one in a long time run but, we can never predict. The destination table also has some random data filled fields that I need to generate and introduce with the old data on this new database. Wondering if mySQL Migration Toolkit can do the job?

[PHP] natural text / human text analysis
Hi.. I'm building a newsscraper -> portal. Fetching, parsing and storing many links to news items per hour was not much of a problem. Translations between languages can be done via google, so that wont be much of a problem either i suspect. I dont want to reveal too much of my business idea, but i do need to do text-analysis, to group related items, and make "suggestions" lists. I've had a dabble with creating my own ontology structure (kinda like a dictionary + thesaurus datamodel) by scraping existing ontology websites, but needless to say natural text analysis is a huge field. One that i'm a total noob in. So in the first place, I'm looking for any free/paid useful existing data-mining / text-analysis code that can be run easily from php. TBH i dont even know my feature-requirements really, i'm interested to know what's available. In the second place, i'm looking for free and published-for-a-cost data-mining / text-analysis papers/books that explain how to produce useful results.

Re: [PHP] I need a fresh look at storing variables in MySQL
the OP may not need such fanciness.. it depends on the amount of reports he wants to store, the types of searches (if any) done by browsers, and the amount of searches to expect. and the OP may not have good db design skills yet. for a noob, it's one timeconsuming thing to build a datamodel, but it's harder to get it efficient yet simple. if the oop wants to start a site with lots of reports and lots of searching, we'd even have to remind him of the cloud hosting option, which i'm sorry to say, has no real rdbms (mysql) support yet, and is not always paid by the minute (but by the hour), meaning it's got only a small chance of reducing his operating cost (by a lot); it's still worth investigating in this case (given the much easier scaling abilities of cloud hosting). OP: if you need a mysql datamodel for reports, i'm willing to give it a free shot. i'm sure others here would too, or improve upon mine. It's probably not more than 3 tables i think. Let us know eh..

Re: [PHP] I need a fresh look at storing variables in MySQL
I'd go with a mysql data modelled approach as it will allow mysql to do lots of the heavy lifting during analysis as you've mentioned. If there are a lot of entries, it's gonna get complex and expensive memory-wise to manage XML or session based datasets. Plus having each question as it's own record should give you greater flexibility in packaging the data for analysis and reporting.

Re: [PHP] I need a fresh look at storing variables in MySQL
+1, but it also kinda depends on what you want to do with it later, and how much. if you want to re-use filled-in reports on the javascript end, you may want to use json_encode() instead of serialize(). if you plan to have many (say >5000) reports filled in and want users to be able to search quickly on values or generate reports based on searches, then you'd need an actual datamodel, so mysql can do the searching, sorting and adding.

A simple find/replace will work in cases like this. I try to write my code so that I don't have to make unnecessary changes to my php.ini. For example, what if I don't have access to my php.ini and can't set a directive in my .htaccess file? What if I'm sharing my code with someone? What if I need to work with outputting XML headers? All of these factors I think outweigh any gains I would get from short tags. As for readability, I tend to use a text editor with syntax highlighting which makes my code readable.

Re[2]: [PHP] Re: PHP Sessions
Hello Ashley,
And if the site is full of that code?)) I think it's worth to learn
what's really the reason of the fact that it doesn't work. Besides
that, it's more readable for me.
And the right thing that was said here is the following: check the
php.ini settings and change them if possible.

That's still using short tags. The time you save on typing is nothing
compared to the time you spend trying to figure out why your script
doesn't work since you moved servers, or copied it to your live server,
or why you are having trouble using XML...

Re: [PHP] Re: PHP Sessions
Hello Martine,
As you have been already told, the is not always supported.
However I'd suggest you to do the following (since I love this form of
tag):
«»
Note: I put within the tag only the variable.

The sessions variables are OK. They don't print when I put them on the HTML
page with this code.
Thank you.
