Re: [PHP-DB] Database question
A really good starting-level textbook is Fabian Pascal's Practical issues in database management. My warm recommendation. It will give you a decent theoretical understanding as well as helping you designing your DB in order to avoid the most usual design mistakes. You will find there VERY important design stuff that you won't find in web tutorials.

[PHP-DB] time slots and PHP/MySQL
this is a big question and i'm not trying to get you to do my modelling for me, but if anyone has experience with this i'd appreciate being pointed in the right direction: How could one efficiently manage time slots in a dB? I mean for example telling the dB that Mike can be somewhere at 6:15 or 6:30 but not 6:45, and that Cynthia can be there at 6:15 or 7:00... ...and so on my instinct is to create a timeslots table, but it looks like it would contain 35,040 records (one for each 15-minute period in the year). egad!

[PHP-DB] Are running sessions using a MySQL handler faster?
Good afternoon! Quick performance question - I'm currently preparing the release of a new website running on a Linux box written in PHP and MySQL with sessions throughout. I've read a bit about changing the PHP session handler to use a database vs. the flat file method. Does anyone have experience doing this? Are there noticeable benefits of making this change? I realize that my /tmp folder will become quite cluttered with session files, but hey - it's tmp so who cares! :) My concern comes in with overall performance of the server - if one method is better than the other.

Re: [PHP-DB] time slots and PHP/MySQL
Don't want to get too philosophical, but don't PIM/Contact Management projects like TWIG have a feature like this? Now, this is just off the top of my head, but rather than create a timeslots table, wouldn't you have an event table, and a member_booked table? The minimum fields in event would be event_id(primary), start_time, end_time. Member_booked fields could be member_id, event_id, with maybe start_time and end_time, these two representing when the member is booked for an event. If a member is not found for a given event/time range in member_booked, presumably she's available. Note that event is generic, and could apply to any resource: meeting room equipment, meeting, etc. Downside to this, is that every member's scheduled event has to go into the member_event table, but it seems small so retrieval and update should be fast. Remember, this is a first kick at the can, and I'd bet there's a better way of doing it.

You're strongly advised not to write your own regex for validating email

valid email addresses. Search archives, or google for some tried and tested
regex which will do the job properly.

RE: [PHP-DB] Date Subtraction
Manoj, Just a couple of thoughts: First, I know this particular topic has been discussed here recently, so you might want to search the archives for more exhaustive information. Second, if you're using MySQL, check out the functions DATE_ADD() and MOD(). They're MySQL functions, so you'll have to implement them in your query, not the actual PHP code itself. These may or may not give you what you're looking for. You might have to drop the value of some kind of PHP variable into the DATE_ADD() INTERVAL parameter or something though. I looked quickly through the date functions in the PHP documentation and didn't find anything that would really manipulate the date for you (of course I may have missed it). The one thing that I did notice is that the PHP date and time functions return the SERVER date and time to you, not the local time for the user accessing your page. That might not be what you want. As I said before, I might have missed something, but that's what I found out after looking for all of two minutes.

James. Many times I find myself wanting a quick and dirty bar chart using only HTML. You can do this simply by creating a one pixel image in any color you like. That way the download is only 1 pixel. Then calculate the width or height depending on if you want vertical or horizontal bars by placing the variable in the height or width and display the one pixel image as such: echo img SRC='images/blue.gif' WIDTH=$percent HEIGHT='18' ALIGN='BOTTOM' BORDER='0'; You can stack different colors. But you only get bar graphs. HTH. Dan. James Hatridge wrote: Hi all.. I'm using SuSE 8.0, mysql, and PHP4. Is it possible to make charts with a database? If so, how about a hint on it?

This is from a php/mysql book. I added the parenthesis simply to group the
sections, and added the {2,3} because a web site tutorial shows that will
limit the preceding section to that many characters (2 or 3 only in this
case).
The script works fine without the {2,3}, and I may have to use it that way,
since another response mentioned foreign addresses, I hadn't taken into
account.
I'd just like to know why it doesn't work, becuase the it's supposed to.

Oh, in MySQL, there's also DATE_SUB(). Forgot to mention that one. Rich -Original Message- From: Hutchins, Richard [mailto:[EMAIL PROTECTED]] Sent: Wednesday, August 21, 2002 2:40 PM To: 'Manoj Japher'; [EMAIL PROTECTED] Subject: RE: [PHP-DB] Date Subtraction Manoj, Just a couple of thoughts: First, I know this particular topic has been discussed here recently, so you might want to search the archives for more exhaustive information. Second, if you're using MySQL, check out the functions DATE_ADD() and MOD(). They're MySQL functions, so you'll have to implement them in your query, not the actual PHP code itself. These may or may not give you what you're looking for. You might have to drop the value of some kind of PHP variable into the DATE_ADD() INTERVAL parameter or something though. I looked quickly through the date functions in the PHP documentation and didn't find anything that would really manipulate the date for you (of course I may have missed it). The one thing that I did notice is that the PHP date and time functions return the SERVER date and time to you, not the local time for the user accessing your page. That might not be what you want. As I said before, I might have missed something, but that's what I found out after looking for all of two minutes.

I solved the problem a week ago. It was just when I wanted to try iODBC when I saw some putenv()-lines in the examples. I put the appropriate lines in my php-script and then it worked. What I don't unterstand is: When I'm running isql in the shell I can connect to the remote-ressource. When I start apache in the same shell I can't connect through PHP, I first have to set the ODBCINSTINI and ODBCINI env-variables. Why don't I need them in the shell?

If they're presenting it as something that you can use in your real-life code

whether they're all as sloppy. On the other hand if they're only presenting
it as an example on using regex then it's fine for learning with.
I added the parenthesis simply to group the
sections, and added the {2,3} because a web site tutorial shows that will
limit the preceding section to that many characters (2 or 3 only in this
case).
The script works fine without the {2,3}, and I may have to use it that way,
since another response mentioned foreign addresses, I hadn't taken into
account.
I'd just like to know why it doesn't work, becuase the it's supposed to.
It's only checking for addresses of the form [EMAIL PROTECTED]
As you can see, the list address ([EMAIL PROTECTED]), and my address
([EMAIL PROTECTED]) would be treated as invalid. Not very clever is it?

Regarding the good sense or otherwise for checking email addresses: This is from a php/mysql book... If it was from page 115, then please turn over to page 116! Regards, =dn -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] form validation question - regex not working
Regarding the problem you are actually asking about:
if (empty($useremail) || !eregi(^([A-Za-z0-9\.\_-])+([A-Za-z0-9\_-])
+\.
([A-Za-z]{2,3})+$, $useremail))
Notice the {2,3} which is supposed to limit the last part to 2 or 3
letters, but I have been testing this and
it allows as many letters as I put in there, but not 1 only.
What's wrong?
Please be aware that I use PCRE not POSIX, but IIRC the last phrase says:
([A-Za-z]{2,3})+$
any upper or lower case letter,
repeated twice or three times,
and that appearing zero or more times, !!!???
appearing at the end of the string.
Remove the + immediately before the terminating $.

[PHP-DB] Re: Date Subtraction
Use getdate() with mktime() and this is your solution. http://www.php.net/manual/en/function.getdate.php http://www.php.net/manual/en/function.mktime.php Adam
RE: [PHP-DB] Date Subtraction
What's more you can do some neat stuff with manipulating the timestamp to create very quick and accurate calendars. For instance for an application I had to build I had need of highlighting weeks on a calendar to change colors every two weeks, but any given day needed to know which color it should show. Since the increment of the timestamp is so predictible you can use the mod operator and do all kinds of neat stuff. Anyway, just another 2 cents worth.
