[PHP] Batch/Prepared statements for Mysql in PHP
I was wondering if there is any current API for creating match/prepare statements, therefore say i have a script to insert, update and insert in the same post, is there a way to reduce to many queries to the database to do it all in one hit ? Although i usually return the last inc id then add it to the second query ? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

RE: [PHP] Script never returns from funktion.
Subject: [PHP] Script never returns from funktion. Hi , i am having problems with a funktion call never returns from the funktion. Now I'm still new to PHP so bare with me if this is wrong. But don't you have to assign the authenticate() function to something as your returning the $username?

I have a large HTML form (~100 form elements) that I used a year ago to
conduct a survey. Now I would like to use this same form but rather than
starting with an empty form I would like to populate the form with a user's
survey response from last year. I have the survey data in a mysql db and I
know how to use PHP to retrieve a user's data. However, the only way I know
to insert a user's data into a form is to embed value=?php echo $var;
statements for each form element (text, checkbox, drop-down, etc). This is
pretty messy, especially for drop-down lists.
Is there a cleaner, easier way to do this?

I have an array with many strings, of which most have spaces or tabs at
the beginning, but no fixed number of them. Example:
$arr[0] = 'Hello.';
How can I separate them into two strings? Like:

[0] = Array
(
[0] = //I added the quotes to notice the space.
[1] = Hello.
)

Thanks! I was just reading that function in the manual when I got your
reply. I tested it but I still have a couple of problems with it.
print_r(preg_split('(\s+)',word1 word2 word3., -1,
PREG_SPLIT_DELIM_CAPTURE));
I get this:
Array
(
[0] =
[1] = word1
[2] = word2
[3] = word3.
)
In [0] the spaces aren't there and it's splitting the other spaces too,
where I need to only split the leading spaces. How should I write it?
TIA,

[PHP] reversing an IF statement
Often I end up using a dumb IF statement which to me seems that
it could have been done some other way.
Example :
if(
($_GET[id]==1) or
($_GET[mode]==home) or
((!isset($_GET[item])) ($_GET[mode]==news))
) {
// Here we do nothing
} else {
// This is where we do it
}
If we translate the above to simpler reading we could say :
if(statement)
// skip
else
// Do the stuff
I'm ofcourse looking for this
if(!statement)
// Do the stuff
Problem is, when using more statements I never seem to find the
way of doing it without having an empty {} in it, dont know if you
see my problem here however, its the best I can exmplain.
For all I know it has to be like this.

I may be wrong though. Note that I used AND instead of OR for the
conditions, because you want them all true at the same time. But then
again, you'd have to test it, with so many conditions it becomes a bit
difficult to picture it in my head :P

You're right, that fixed the space capturing.

...I wonder why you're doing this, but here's an answer for you.
BTW, if you use var_dump or var_export, you can see the whitespace :-).
$arr = preg_split('/(^\s+)/',word1 word2 word3., -1,
PREG_SPLIT_DELIM_CAPTURE);
The ^ means beginning of string.
This will still give you an empty string in $arr[0], so do something
like:
unset($arr[0]);
$arr = array_values($arr);
Or just write your code to expect the extra entry. ;-)
The ^ did the trick, thanks! I noticed the empty [0].
I'm doing this to display code in an indented way and to keep the indent
if the line wraps, instead of going back all the way to the left. So I'm
putting the spaces in a td and the code line in another td, with a
table for each line. I tested it and looks very well, now I'm writting
the code to generate it.
Thank you all for your help! :)

Hey, Next week I will be attending the International PHP Conference in Amsterdam and since I don't know anybody who will attend I thought it would be nice to get some contacts before I go. I'm sure there are some people on this list who will be going to the conference, so I thought this might be a good way to find some people to 'socialize' with since three days can be quite long ;) Anybody who is not coming to Amsterdam can read my weblog (http://www.filipdewaard.com), where I will post daily updates about what's going on at the conference.

How about something like:

I haven't tried this particular preg_replace, but the 'm' option is the
important one that tells preg_replace to use the whole string instead of
breaking it up by lines.

Re: [PHP] Select from 24 tables
This isn't always desirable, or even possible. I once designed a database to hold characteristics for a series of 70 different tests. There were about 50 different characteristics used in various combinations for each test. Each characteristic could be one of many values. So the characteristics tables all looked like this: id, name, value And the test tables looked like this: id, name, value And the mapping of characteristics to test looked like this: test_id, characteristic_id This is actually a gross oversimplification, but you get the idea. Displaying test results typically required joining 30-40 tables together, but since each characteristic table was small (10-15 entries), performance was acceptable. So do as John Nichel first suggested, and do this: select c1.id as characteristic1_id, c2.id as characteristic2_id from characteristic1 c1, characteristic2 c2 etc. cheers, Travis John W.

Often I end up using a dumb IF statement which to me seems that
it could have been done some other way.
Example :
if(
($_GET[id]==1) or
($_GET[mode]==home) or
((!isset($_GET[item])) ($_GET[mode]==news))
) {
// Here we do nothing
} else {
// This is where we do it
}
If we translate the above to simpler reading we could say :
if(statement)
// skip
else
// Do the stuff
I'm ofcourse looking for this
if(!statement)
// Do the stuff
Problem is, when using more statements I never seem to find the
way of doing it without having an empty {} in it, dont know if you
see my problem here however, its the best I can exmplain.
For all I know it has to be like this.

What do you think?

I may be wrong though. Note that I used AND instead of OR for the
conditions, because you want them all true at the same time. But then
again, you'd have to test it, with so many conditions it becomes a bit
difficult to picture it in my head :P

The easiest method is just to encase all the checks in parenthese, then
negate it:

)) {

[PHP] Sorting text with multibyte characters
Hi, Does anyone have any thoughts on how to effectively sort text with multi byte characters? I am working on a project that uses lots of German text, and the letters with umlauts don't sort correctly. I'm using the mb_* functions in a few places (to adapt an ASCII-encoded database to XML output for flash, which is always expected to be in UTF-8), but none of them seems to be made for string comparison. thanks, -mike. - michal migurski- contact info and pgp key: sf/cahttp://mike.teczno.com/contact.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I.e., go with John Holmes' suggestion before you're really up the creek. Up what creek? You didn't really provide any technical justification for your suggestion. In my experience, the best way to deliver a quality application is to start with a fully-normalized database schema, then de-normalize it slightly here and there if performance is really a problem. But I've rarely had to do that. In most cases, an upgrade to a faster server with more memory solves the problem more quickly and cheaply than an application re-write would. On the other hand, I've been called in many times to deal with application problems that arise from using mashed-together schemas such as the one you propose. John W.

I don't think it's a good idea to optimize the database schema for the sake of the programmer, who only has to write the SQL one time. Later, when the customer wants to fix bugs, or add enhancements, the pain is far greater. That's usually when I get called in, long after the original programmer has flown the coop. The only times I ever purposely deliver denormalized applications such as you suggest are when the customers are asking for quick-and-dirty stopgap solutions. Then it makes sense to optimize for the application writer. However, I have found that stopgap solutions have a way of becoming permanent. These days, I usually turn down such jobs. cheers, Travis -- Travis Low mailto:[EMAIL PROTECTED] http://www.dawnstar.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] php user management functionality
I wrote a job-tracking/workflow management application called Willow Job Tracker. You can download a copy of the free GPL version from here: http://dawnstar.com/index.php?display=ProductDetailsid=780 And there's a demo here: http://dawnstar.com/wjtf/ Login to the demo using admin/admin. Currently, only the MySQL DB is supported, but you can add support for other databases by implementing the Db.class.php for each database. Also, there are no provisions for denying based on IP, but you could add that pretty easily. Though I question the utility of that, since so many people live behind firewalls. As for user registration, you'd have to clone the Add User page to make a Registration page, but that should be pretty easy too. Other than that, I think it has everything you listed. You'd have to rip out the job tracking stuff, but frankly, you could just remove the links and leave the code. There is also extensive documentation to help you get started with your customizations. Have fun. cheers, Travis bruce wrote: hey doing some basic research... has anyone found a seriously good user management script (preferably free) that can be incorporated within a web application. i'm looking for something that allows for the following functions: - user registration/login - admin function - group/team definition - email verification - database driven (mysql/postgres) - ability to grant user multiple rights/access levels - ability to check/deny by IP Address - session based function - page security - linux/apache/php we've seen a few, but nothing that really grabs us we're considering taking something like phpbb/gforge and just ripping the login/admin function out, although we'd prefer another approach but if we have to rip the functionality out of another app, has anybody seen an app (open source/free) that has a serious login/admin/user management function that we should look at... thanks bruce [EMAIL PROTECTED] -- Travis Low mailto:[EMAIL PROTECTED] http://www.dawnstar.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Select from 24 tables
Up what creek? You didn't really provide any technical justification for your suggestion. Up the creek of having to call for help on php-general because you have 24 identical tables you need to join, having never performed a join before. The pain only occurs when writing the SQL statements to join the tables. I don't think it's a good idea to optimize the database schema for the sake of the programmer, who only has to write the SQL one time. I wholeheartedly disagree. :) I think that optimizing for the sake of the programmer, the bug fixer, and the possible inheritor of the project is a /great/ idea. Servers keep getting faster, while the human attention span and rate of familiarization with code stays approximately constant, so optimizing your development time is at least as sensible as optimizing SQL select performance, which is probably better handled through well-chosen indexes anyway. Optimizing for the programmer usually translates into thinking about the humans who will need to interpret your code, and making it easy to pick up the gist of your intent. A 24-table join is not a typical characteristic of what I'd consider a well-planned DB schema, whose meaning can be quickly grokked by a newcomer to the project. If all those 24 tables store the same kind of data, then there's no reason to split them up. Of course, we haven't seen the specific usage of those tables in this thread, but I'm basing my posts on the assumption that it's better for the OP to have a marbles table with a color column, than tables named red_marbles, blue_marbles, 'green_marbles, etc. If that's not the kind of data we're talking about, then I stand corrected, and John Nichel's initial response is all that's needed. A huge table count is often evidence of a need for some refactoring. - michal migurski- contact info and pgp key: sf/cahttp://mike.teczno.com/contact.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Php MySql selection question
* Thus wrote Dave Carrera ([EMAIL PROTECTED]):
Hi List,
I am trying to make a search box for my site and I ask the list how can I
search 24 tables to find a search string posted by a form.
oohh.. ouch ;)
I get Column: 'listing' in where clause is ambiguous when I run
$sql = mysql_query(select * from $tbs where listing like
\$_POST[tglstring]\) or die(mysql_error());
$tbs is a string containing 24 table names (1 for each letter of the
alphabet).
You cant search tables like that and get back what your expecting.
If you have two tables say:
create table t1 {
id int,
name varchar(50)
)
create table t2 {
id int,
name varchar(50)
)
If you select from both of those tables like:
select * from t1, t2
The field list returned from mysql will be:
id, name, id, name
And If you add a condition to the sql statement:
select * from t1, t2 where name like 'foo%'
Mysql complains about ambiguous column, because It has no idea from
which table you want 'name' to be like. And even if you did tell it
what tables too look at:
select * from t1, t2 where t1.name like 'foo%' or t2.name like
'foo%'
Your data is going to be all messed up anyway. You can use a UNION
statment to fix this problem or restructure your data so you dont
have this problem, the later being prefered method.
You should get on the mysql mailing list. I think i've already said
to much about mysql.

Re: [PHP] Select from 24 tables
Hi Michal, Getting back to the original posting, I'm basically saying that I don't think it's a good idea to structure or restructure a database for the sake of simplifying a few SQL statements. Especially if the data being joined is in separate tables for a good reason. Regarding optimizing for programmer/bug-fixer/etc, after thinking about it, I realized that what constitutes optimization really depends a lot on your development situation, so I'll refrain from further comments on that. I probably shouldn't have brought it up, sorry. cheers, Travis Michal Migurski wrote: Up what creek? You didn't really provide any technical justification for your suggestion.
