[PHP-DB] Help in tokenizing a string
Good day to all.
I tried the following code from PHP's manual
if (isset($submit))
{
if ($submit == "Save")
{
echo "$im_file";
$tok = strtok($im_file, "\\");
while ($tok)
{
echo "$tok";
$tok = strtok ("\\");
}
}
}
I have the string $im_file ="C:image.jpg" and I want to have
into a variable (say it $im) just the filename part (image.jpg).
The code above, returns me just a "C:" :((
Any suggestions greatly appreciated.

RE: [PHP-DB] More Date operations.
you have changed the command from when you do it in mysql to when you do it
in php - you are leaving out the "'" quote marks around the date you are
passing :)
// $sql="SELECT TO_DAYS(2001-01-01) AS bar";
should be

Re: [PHP-DB] Re: MSSQL Query - Unicode data in a Unicode-only collation or ntext data cannot be sent
Yeah, I create a simple table with simple char data type. Works great.
No, sorry, I don't know T-SQL. I've just started using MSSQL. I've only
used MySQL, and even that was using very simple queries. Once I have a
better understanding of MSSQL, I will probably pick up the T-SQL book.
Thanks.

Re: [PHP-DB] Re: MSSQL Query - Unicode data in a Unicode-only collation or ntext data cannot be sent
No worries, there's an "IIS-Lockdown" Tool available from Microsoft if you
want to play around with IIS - and not have to worry about code red etc (you
still need to keep it regularly updated patches wise though - I guess thats
the advantage of apache).
The sample script is fine - thats how I got into MSSQL/PHP many moons ago.
Note that it isn't very efficient (you can write a much faster script using
mssql_fetch_array() and arrays) as it makes a lot of requests on the db. I
think you are better off creating a simple DB in MSSQL enterprise manager
(dead easy once you get the hang of it - much better than access IMHO but
thats not very hard!).
Do you know anything about Transactional SQL? If you do you might be able
to help me in return (see my question in another newer thread)!
If you want any more help let me know, I have been using this stuff for a
while and don't mind sharing info (seeing as I'm probably not going to get
to use PHP once I'm a graduate in a few months).

Re: [PHP-DB] Re: MSSQL Query - Unicode data in a Unicode-only collation or ntext data cannot be sent
Hi Ollie, Thank you for your reply. I was mistaken. I am using PHP 4.1.1 loaded as a CGI. I am using Apache because I am from a Solaris/Linux background, and I know how to use it better. I don't feel comfortable enough with IIS to secure it down (with all that NIMDA and CodeRed floating around). Our company is going to implement SQL Server 2000, so I want to try it out. I used the sample PHP script from PHP's Web site to connect. Here is the code: 0) : print "Data:"; while ($i < $number) : $name = mssql_result($result,$i,"Name"); print $name; print ""; $i++; endwhile; endif; ?> I modified it to grab information from Northwind's Employee table. I didn't know Unicode was something that was defined. I will try to make a sample database with 'more simple' database fields to see if that works. I just wanted to do a quick test to grab data. I see it'll take me a little longer to learn MSSQL.

[PHP-DB] renaming uploaded files
Hi php developers: I have created a website for a house renting company with an administration tool. Using this tool, managers can add, modify and delete data in a mysql database. They can also upload some pictures of the houses they rent. The way i do this is by taking them to the list of houses, making them select one and next they go to a form. In this form they upload files to a certain folder in the server. What i would like to do is auto rename the file with a name composed by IDNUMBER + NUMBER OF PICTURE (ex. if ID of that house is 345 image name would be 34501.gif, 34502.gif, 34503.gif,...) I think you got the idea. Any help would be greatly appreciated. thx in advance -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Hi there, PHP4.0.6 on IIS / Windows 2000 works fine with SQL Server 2000 (I have teste this quite throughly) I don't know about unicode fields however as I don't/ haven't used them in any of my databases. I know that varchar fields have a few issues (can't retrieve more that 255 characters, you have to use text fields instead - which aren't queryable). What are you using to connect to MS-SQL?

[PHP-DB] Ensuring users don't overwrite each other (NOT a newbie question)
Hi there, currently writing an e-CRM system for an intranet using PHP on Win32 and MS-SQL. This system needs to be scalable but more importantly there will be anything up to 400 users (unlikely, but the max amount) using the same records (updating information about customers etc) and I worry that whilst one user has a form open (via one of my PHP scripts) that another user could also be making changes to the same record and if they post it before the other one they could overwite each others changes. For info: database is normalised to 3NF so that side of things should be okay. I have thought of a couple of solutions: Row Locking when a user has a record - and if another user wants to use that record PHP tells them its in use. But if the forst user doesn't make any changes how will the db know to unlock the row and there might be potential deadlock issues. Also I'm not sure of the SQL for row locking (do you use a SELECT with a ROWLOCK hint?). Another idea was to have a log or temp table - that would get written into when ever some opens a record but this has the same issues as the first solution I think. An another idea is T-SQL and transactions but I'm not sure if that will solve the problem (and I've never used T-SQL before - therefore I'm not sure of its capabilities) eg: When the script is started by the first user (to bring up the existing record) perhaps a transaction is started (if they can persist between batches?): $tranname = "@tran".$id; $sqlstr = "TRANSACTION $tranname SELECT rows from CASES WHERE id = $id GO /* maybe find the date / time from a system table sp_something of the last time the row was modified?? */ START TRANSACTION $tranname GO "; But that probably won't work thinking about it (and looking at the stupid senseless code I have written above) The transcation probably need to be around the update SQL doesn't it? And then do a rollback if it finds another user has updated lately? And then reload the data and send it back to the form for the user to check (then they can update - after checking the other users data?) Anybody have a solution /views on this? Anybody had to fix a similar problem? Or is all this paranoia (will the DB handle this problem on it own? - I very much doubt that last comment!) Any help would be most appreciated, I don't need all of the PHP code just the concepts will do (I have been using PHP/MS-SQL for a while) or some example T-SQL if you think thats the solution I should go for.

=the goal is still not clear to me, and if you want to critique this response, or ask

the system being
constructed... I've tried to work with this information on a theoretical basis, but it
makes the job more
difficult, not to know what we're actually working with!

ncpte and there is no need to consider them as 'couples' - only need to deal with
naffaire.
=to count the number of occurences of each naffair value (couple):

Re: [PHP-DB] Re: Date operations.
Frank,
As yet no response from Garry, but I wanted to ask:
You already have DateTable set up (presumably), so extending its application into a
relationship with the
breeding table is no big deal. Given that one suggestion was that Garry could consider
storing monthly
statistics in another table (from breeding), and thus saves processing each time/only
needs to update once per
month and presumably only for the month just passed; wouldn't it make sense FOR HIM to
combine the two
functions? Initially create the MonthlyStats table to contain only year and month data
(which can be related to
'drive' date-oriented SELECTing), and then update/populate each month's row as and
when the stats become
available. It might also offer opportunities to simplify the processing outlined below.
Your thoughts?

[PHP-DB] phpMyAdmin Problem....
I just added phpMyAdmin to a new Apache Server, and I'm getting this error: cannot load MySQL extension, please check PHP Configuration. I did some research on the web, but couldn't come up with a solution to this error and couldn't find anyone listing it. Does anyone know if this is a problem with conf.inc.php in phpMyAdmin or with the MySQL set up in PHP on the server? Any suggestions from there?

[PHP-DB] NULL Values
I have a loop process that reads a record out of a flat file, stores the data for a given record in an array, writes the record to the db, resets the data in the array, then iterates again thru the loop. Not every record has a value for each field. For example, Not every record has a value for the field "cus034a". Since this is numeric type data, I do not want the value in the db to be "0" if there is no value for the field (it should be NULL). # partial table definition cus034a TINYINT UNSIGNED NULL, sat01 TINYINT UNSIGNED NULL, What I try to do is set the array to NULL values before iterating the loop again. However, if I do this and the next record does not have a value for "cus034a", the value in the db still ends up being "0". $data_array["cus034a"] = NULL; $data_array["sat01"] = NULL; I must be doing something wrong?

[PHP-DB] Strange re-include/crash problem with Oracle (OCI8)
Hello, I have PHP 4.0.6 compiled as an Apache 1.3.20 module with OCI and MySQL on RedHat 6.2. Things work nicely, except for the following situation: When connecting to the remote Oracle server, if the server happens to be down or unavail, I get, what appears to be, re-inclusion, even though I use require_once(). For example I get this thrown on the screen: Warning: Constant sid already defined in Unknown on line 0 Warning: Cannot send session cache limiter - headers already sent (output started at /usr/local/apache/htdocs:65) in Unknown on line 0 Warning: Constant godroot already defined in /usr/local/apache/htdocs/base.inc.php on line 3 Warning: Constant servername already defined in /usr/local/apache/htdocs/base.inc.php on line 5 The error then continues with all my top-level defines() in base.inc.php. I have session.auto_start=1 and session.use_cookies=1 in php.ini. Additionally, the error I get from Oracle is: ORA-03113: end-of-file on communication channel Although this is the error I get recently, I have found that this problem also occurs with other various connection-type Oracle errors. Additionally, a look at Apache's error_log shows: [Thu Jan 31 08:03:02 2002] [notice] child pid 20749 exit signal Segmentation fault (11) [Thu Jan 31 08:04:16 2002] [notice] child pid 20757 exit signal Segmentation fault (11) [Thu Jan 31 08:04:20 2002] [notice] child pid 20753 exit signal Segmentation fault (11) Although if I hit the refresh button, all the Warning: messages go away. If Oracle is still down, the normal Oracle message is shown, as expected. So in other words, this only happens right after trying to load the page for the first time with Oracle being down for one reason or another. Any help or explanation would be great, as the end-user doesn't like seeing all the Warnings, as opposed to: Oracle Database Down. If anymore info or clarification is needed, please don't hesitate to ask.

Remove the \"\".
Next, whenever you have a problem with a query, print mysql_error() as part
of your die() statement. Finally, print your $sql to ensure that it
contains what you expect.

Try using single quotes:

Location, Date)
VALUES
('',
'$id', '$Industry', '$Other', '$JobTitle', '$Description',

I don't think you really need a connection class, per se. What you want to do is write the connection code for the database once and then be able to use it in all of your pages, correct. How about this: db_connection.php Then in each file, at the top: And you would call your queries like this: $query = 'SELECT au FROM pb WHERE alchemy!="junk_science"'; $res = mysql_query($query, $dbh); >From there you need to use the fetch_row/array functions as described in the PHP manual. If not using MySQL, change the "connect" call to the appropriate function. The above assumes that you are just talking to tables in one database. If using more databases, put the select_db call in the individual files. Also, if your db_connection.php file isn't in the same directory as the files requiring it, use an absolute location or put the file in your include path. HTH.

[PHP-DB] DB Connections
Ok, I am having a hard time coming up with a mysql connection class that simply allows me to setup a require(db_connection.inc) at the top of my php pages that allows a consistent connection to the mysql db and allows multiple queries thoughout the php page in question. I have read a few tutorials on it and as of yet they all seem to go over my head. If someone could give me some more insight into this area I would greatly appriciate it.

[PHP-DB] Connection class
Ok well I am in a little over my head with a connection class that I can use over and over for multiple queries against a mysql db on one page. I have read a few tutorials on the subject of how to use class files but I still dont understand php enough to know how to make a connection class that simply allows me to connect to a mysql database once the page loads and keeps the connection to run multiple queries on the same page.

RE: [PHP-DB] left joins and mysql
First, don't try to force JOIN to do something that is is not designed to
do. Use WHERE to restrict your query.
Try:
SELECT t.team_name,t.flight_id,p.player_fname,p.player_lname
FROM team t
LEFT JOIN player p ON
t.team_id=p.player_team_id
WHERE t.flight_id=p.player_flight_id && p.player_status='captain'

Hi,
I am trying to do a left join on a "master" table, but I don't want to pull

Is this possible, or do I have to pull all the records from the master? I
have a table called "team" that is the master, I want to join a table called

(flight_id), not all teams (there are eight flights in the "team" table).
Below is the basic syntax I am using now, and it is pulling all the teams
from the team table, not just the teams where flight_id=1. Is there
someplace after the "join" that I can restrict "team" records using a WHERE
statement? Sorry if this is confusing.

Re: [PHP-DB] Adding to an empty field
Assume query looks OK when you echo it? You're not seeing a literal "$id",
are you?
Does an id exist for $id? Is it numeric or char?
Check mysql_affected_rows() - what does it return?

[PHP-DB] Using actual variable values after retreiving from db
Hi,
I used to store SQL code for a transaction
directly in the PHP script which used it. It was
stored as a string. However, now I want to store
it in the database and assign it to the same
string that held it before. Not very clear, so
heres an example :
Before:
$sql_variable = "select whatever from table";
Now:
$sql_variable = getSQL("whatever");
However, because the SQL contains variables which
were filled at run time, it does not parse the
variables when it assigns the string to the
variable name. So I get errors because when the
SQL runs on the database it runs as :
select * from $table_name,
rather than
select * from whatever
Hope I have explained this OK. Are there any
solutions? For example, force it to parse a
string for variables and assign their values
again?
Thanks in advance

[PHP-DB] OK all you SQL gurus...
I'm trying to figure out a way to do a more efficient join on four tables.
The main table is products, with the other tables being common options for
the products. It's pretty well normalized, but am I doing these joins
properly or is there a more efficient way? This looks pretty ugly to me.
-
$q = "SELECT man.name as brand, category.proper as propername, products.*
FROM manufacturers as man, products, category, type
WHERE products.catid = category.catid AND man.manid = products.manid AND
type.type_id = products.type_id AND category.name = '".$category."'";
if (isset($type)) {
$q .= " AND type.type = '".$type."'";
}
-
Any suggestions, or am I ok on this?
Much thanks,
Mike
