[PHP-DB] Mysql and DBF files
Hi. I have a problem that I hope some of you may have an answer... I'd like to use some dbf files I created using clipper with php and mysql. I don't want to transform the data from one database to another but I want to have access to them by both php and another program built with clipper at the same time. I was told that this is possible with ODBC drivers but haven't actually tried yet. Does anyone here know something about this? Thanx in advance... Achilles

[PHP-DB] RE: [PHP] date problem
SELECT COUNT(*) AS c FROM users_table WHERE UNIX_TIMESTAMP( user_regdate ) '1022882400' The only way you can do it with a char column is to select the entire database, load it into a PHP array, using strtotime() to (hopefully) convert May 29, 2002, etc, into a unix timestamp, and then sort by that timestamp. Alternatively you could use the query you are now (if its returning the correct subset of rows from the table). Replace COUNT(*) AS c with your primary key field (eg: id), and then use mysql_count_row() [rtfm for more details] rather than pulling the rows. From here it looks like your fastest option, but your not providing enough information. -- Dan Hardiker [[EMAIL PROTECTED]] ADAM Software Systems Engineer First Creative Ltd -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

RE: [PHP-DB] cookies and Global variables
When you get the Header already sent error, that means that you are trying to send header info, e.g. cookie info AFTER you've already sent some header info. This is usually seen when your php script has an include in it (above your cookie stuff) that contains some html. Check your includes, and make sure that the header info is the first thing sent.

[PHP-DB] Deleting old sess_... files from /tmp dir
Hello, We're trying to use session variables to store a user's database login information. I am wondering how to automatically delete the old sess_... files from the /tmp directory which are used by PHP to store session variables. Is there a way to set PHP to do this? I've tried setting the session.gc_maxlifetime in the php.ini to a lower number, but had no luck. I suppose a last resort is a script that runs in cron to delete the old files. Our environment is: Solaris 7, PHP 4.1.2, Apache 1.3.22. Thanks in advance for any advice you may have.

[PHP-DB] fopen() question
I have a database and I am writing a script to auto-update some information
in the database.
That requires me to read data from database, find the URL, read the URL,
find the information I want, then update it in the database.
My problem is, for example I read one record from database who's URL is
http://www.somedomain.com/.
And I try to read the URL with fopen() for information:
$fp = fopen(³http://www.comedomain.com/², ³r²);
if (!$fp)
{
echo ³URL not available.²;
exit;
}
If the URL is available, things will work fine.
But if the URL is NOT available, I will get a error saying ³attempt to load
file ³MyFile¹s URL² failed² from browser.
It¹s supposed to output the string ³URL not available², isn¹t it?
Anyone know how to get around with this?

Re: [PHP-DB] fopen() question
Also, if you check many URL's from the same script, make sure neither
PHP nor the browser times out. For PHP, set_time_limit() and for the
browser echo a space and flush() after each test.

[PHP-DB] MySQL problem on Yellow Dog Linux
I'm a relative newbie to the Linux/web server world, having worked with Macs most of my life. I recently installed the Server install of Yellow Dog Linux, with no window managers, CLI only. Everything is working pretty much correctly, except PHP interaction with MySQL. When I tried to install Invision Board, I got the following error Fatal error: Call to undefined function: mysql_connect() in /var/www/default/forums/sm_install.php on line 249 I figured this meant MySQL or PHP was configured incorrectly so I installed PhpMyAdmin to see if that would work, and I got the error message cannot load MySQL extension, please check PHP Configuration. What needs to be configured? I was under the impression that MySQL support was built into PHP now and that it needs no extension. I downloaded the RPM of PHP 4.1.2 (the latest PPC RPM available at rpmfind) and it told me it was already installed. I then installed MySQL 3.23.41 to no effect. So what can I do to fix this? -- -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Well, the MySQL library comes bundled with PHP, but to actually build in
support, you need to configure it with --with-MySQL.
I'm not a big RPM guy, but you should probably look for an RPM for PHP that
mentions MySQL as well.

[PHP-DB] Weird intermittent No Database Selected problem
Help!
I've been having a weird problem today (and maybe it's been there all along,
just haven't noticed...it's only been live a few days). I have a web page
that allows users to query my database by either subject or alphabet (A-Z).
Today (and I think I noticed it once before but didn't pay much attention),
if you do a query, the first time it comes back with the results. The
second time, clicking the same letter (or sometimes other letters), for
instance, it comes back with a Database Not Selected error. Or, every
time in a row for a dozen times it comes back with a Database Not Selected
error. Or, sometimes it comes back with the results just fine for twenty
times in a row. Or, ...
You get the idea. It doesn't happen all the time, just sometimes, and in no
particular order. Very strange because I'm not changing a dang thing.
Anyway, I've already tried rebooting the server, no change. And, I've tried
accessing the web page from other machines, same problem. Has anyone ever
run into this?
I'm running Red Hat 7.2, Apache 1.3.23, MySQL 3.23.49a, and PHP 4.2.1.
Here's the code in the web page with only some name changes (for security,
ya know):
?php
function Query()
{
global $mydb, $recordset, $total_rows, $letter;
$letter = $_GET['letter'];
mysql_select_db($database_mydb, $mydb);
$query = sprintf(SELECT name
FROM tbl_mytable
WHERE name LIKE %s
ORDER BY name ASC,
SQLStr($letter . %, text));
$recordset = mysql_query($query, $mydb) or die(mysql_error());
$total_rows = mysql_num_rows($recordset);
}
?
And then the code in my include where I keep all the db connection stuff:
?php
$hostname_mydb = localhost;
$database_mydb = mydb;
$username_mydb = user;
$password_mydb = ;
$mydb= mysql_pconnect($hostname_mydb, $username_mydb, $password_mydb) or
die(mysql_error());
?
Any help is appreciated!! Thanks!

[PHP-DB] Splitting a string and placing the contents into a form pulldown

[PHP-DB] Splitting a string and placing the contents into a form pulldown Solved
Hi there everyone,
I've found a solution that works for me for the problem I was having
earlier with splitting a string and then having populate a dropdown box.
I don't have time to add it to the page requested earlier as I am really
rushed off my feet so if the guy who requested it could do it, that
would be great :-)
Here's how I solved my problem, probably a better way, but this works.
I have the following string:
Deluxe double £165.00 prpnbrbrSingle £128.00 prpnbrbrTriple
£229.00 prpn
And I needed to take out the BR's and have each item in an array, then
populate a form pulldown field. In short, here's the code I used in the
end - if anyone can see a better way I'll be all ears :-) Though this
is short, sweet and does what it needs to do.
$last_minute_room_rates = str_replace(br, ,
$last_minute_room_rates);
$keywords = preg_split ('prpn', $last_minute_room_rates);
and for the form:
select name=RoomType?
foreach ($keywords as
$keywords) { ?
option
value=?=$keywords??=$keywords?/option? } ?
/select
prpn /td
As you can see, I used the common prpn (Per room per night) at the end
of each item as a reference for the new Array item. This removed the
prpn from the dropdown but I solved that by simply hardcoding that to
the right of the dropdown box :-)
Regards
Chris Payne

[PHP-DB] RE: [PHP] Weird intermittent No Database Selected problem
Thanks for the help, all! Here was the problem...I think, I'm pretty sure,
eh?
In mysql_select_db($database_mydb, $mydb), I have the variable,
$database_mydb, which is actually something that Macromedia's Dreamweaver
MX created (for those that don't know it, Dreamweaver MX supports a little
PHP).
Well, not to put the blame on Macromedia, it was all my fault and I now feel
a bit stupid, I think it all boiled down to $database_mydb not being
declared global in the function I wrote to do the query.
Funny that it worked probably 95% of the time. Must have been due to
mysql_pconnect or something holding open previous connections to the db and
the script just connecting to the last connected db. Anyway...
Sorry for the trouble!

Are all the variables needed for the function getting into your
call_user_func()? Also, perhaps some aren't set or are being
unset outside
your function--say, you are opening a new page and not passing all the
variables to it. The function (which apparently works) isn't getting set
variables. Try echoing the input variables just above the
function call and
see if they're all there.
Hope this helps,

I assume you're not checking the status returned by the
database function calls, becuase they'd probably give
you valueable information on *why* it's doing that. :)
try checking the return val, and (if using mysql) print
out mysql_error() if you get a bad return val.
