[PHP] running number
I am required to write a user registration script that captures the basics like name, phone number etc etc. I would also have to write to mySQL database a number that is associated with that user. At this point of writing, the start of that number is unknown. But the number will be incremented by 1 after each successfull registration. Let's say the number starts from 12345. I am quite new at all these stuff and would like to seek your advise on the *recommended way* of achieving this. I am thinking along these lines: a) store that number (12345) in a table b) a user registers and assign that number to him c) increment number to 12346 d) process repeats for the next registration Concern: How do tell mySQL to lock the 'number' table when a new registration process is about to take place.

[PHP] Closing persistent ODBC connections
Hello everyone, The php manual isn't very clear about when and how ODBC persistent connection are actually closed. I tried with odbc_close_all() but I'm not sure it really closes the connection, since the next call to odbc_pconnect() will be faster than before! The problem is that regularly I really need to close all connections to the ODBC for maintenance... And I would like to do this without shutting down apache ;) Thanks for all your advices!

thx,
PHP is case-sensitive. UppERCase is NOT the same as uppercase. HTML is
not case sensitive only because browsers are forgiving.
PHP variables are case-sensitive.
PHP FUNCTIONS are not.
You're on your own figuring out if class names/methods are/aren't
case-sensitive this week. :-v
1. classname are case-insensitive (at least in all the builds I have running)
but since 5.0.1 (IIRC) the engine honors your case when using get_class(),
in the past the class name was always returned lowercase. so:
php -r 'class Test {} $t = new Test; if ($t instanceof test) { echo yeah!\n; } echo
get_class($t),\n;'
will echo:
yeah!
Test
2. methodnames are the same as functionname with regard to case-sensitivity
3. constants (and class constants) are case sensitive.

[PHP] A strategy question about using mySQL for saving flat-file stings?
I've been creating a number of CM applications for a virtual-host website. One feature, of several applications, allows the editor [one of our people] to create simple text files. I've been using simple flat-files in a directory for saving the files. I've gotten tried of dealing with directory permission problems, etc., and am considering using a simple mySQL DB for storing the file strings. Obviously, for each file-string to be unique, its path must be included as part of the ID. Here is my question. I can use one table for all the path/files and use the following as the primary key /home/some-dir/filename. fields: fullpath-filename | path | type | date | binary-string path is so the code can do an equivalent of scandir() type signifies whether data has been serialized() or not. This is so I can save arrays date is the equivalent of file last mod date. Or, I can create a separate table for each full-path used and then just use the filename for the primary key. In this case, since the table name is in effect the path, only the filename is needed. The first approach is obviously simplest; but, I'm concerned about getting myself into a trap later on.

[PHP] A directory permissions question
I'm on virtual-host server and have been following a rule of making certain all directories on the root have permissions set to 755. This is the default when creating new directories with ftp, etc. Occasionally, I need directories with 757 and have always made certain they were not on the root. I've started thinking about whether my rule really makes any sense for security reasons. In general, the site is well protected by the host's security measures and my use of the Apache basic authorization where needed, etc. Comments and suggestions???

[PHP] Wierd time shifting problem?!?
Greetings, I have an application I built that allows the user to schedule mailings to subscribed users for specific times and dates. Everything was working fine as far as I could tell then all of a sudden this time shifting problem started popping up and seems to be getting worse. The application makes extensive use of the date() and time() command for generating and displaying dates and times. It appears that the times are shifting 7 hours into the future. If I shutdown Apache then start it back up next time I log into the application all of the times are now displayed correctly. Below is my server configuration: - Windows Advanced Server 2000 with all updates applied - Apache 2.0.47 non SSL - PHP 4.3.3 using Apache2 module - MySQL 4.0.14-max - phpMyAdmin 2.5.2-pl1 The application itself also makes heavy use of: - Adodb 4.52 - Smarty 2.6.5 I am hoping someone can at least point me in the right direction here as this is starting to become very annoying. We are going to be moving the application over to an Mac OSX 10.4 server in the near future but I still need to find out why this is happening on the Windows server. I have never had this type of thing happen on this server to my knowledge. I am going to be upgrading Apache to 2.0.54 and PHP to 4.4.0 probably today to see if this helps. I have also considered moving Apache back to the 1.3x series as I have heard that the 2.x series has some stability problems on Windows. Anyways, thank you in advance to anyone that can help me!!!

[PHP] Prepopulating form fields afer an error
Hi,
I have a form and it does basic error checking after submission; when
the user omits required fields it kicks back the form with highlighted
errors telling them the error of their ways.
I've sussed out that by populating the value of the field with
$fieldvalue I can have that form field populated with the data the
user *did* enter for that field:
something like
input type=text name=email_address value=?php echo $email_address?
That works great. But how can I do the same thing for drop down boxes,
when they select an option?
I tried the unwieldy,
select name='blah'
?php if (!empty(blah)) {
echo option value=';
echo $blah;
echo '
echo $blah;
echo /option\n;
}
?
And that, lo and behold, didn't work. Can anyone offer a suggestion?

The following is an HTML code snippet with embedded PHP code for the
intelligence.
select name=shipper
option value=DHL ? if ($shipped_via == DHL) echo selected;
?DHL
option value=FedEx ? if ($shipped_via == FedEx) echo selected;
?FedEx
option value=UPS ? if ($shipped_via == UPS) echo selected;
?UPS
/select

Subject: [PHP] Prepopulating form fields afer an error
Hi,
I have a form and it does basic error checking after submission; when
the user omits required fields it kicks back the form with highlighted
errors telling them the error of their ways.
I've sussed out that by populating the value of the field with
$fieldvalue I can have that form field populated with the data the
user *did* enter for that field:
something like
input type=text name=email_address value=?php echo $email_address?
That works great. But how can I do the same thing for drop down boxes,
when they select an option?
I tried the unwieldy,
select name='blah'
?php if (!empty(blah)) {
echo option value=';
echo $blah;
echo '
echo $blah;
echo /option\n;
}
?
And that, lo and behold, didn't work. Can anyone offer a suggestion?
Thanks in advance
JJ

Re: [PHP] How would you create a tracking pixel?
I did some more STFW and came up with this - I'll try it to see if it works.

Re: [PHP] running number
CREATE TABLE `users` (
`num` int(10) NOT NULL auto_increment,
`name` varchar(100) NOT NULL default '',
`login` varchar(100) NOT NULL default '',
`password` varchar(20) NOT NULL default '',
PRIMARY KEY (`num`),
KEY `num` (`num`)
) TYPE=MyISAM AUTO_INCREMENT=12345 ;
That should help out. When creating the table in mysql you can set the
auto_increment number on the last line, which when you add a new user the query
looks like:
insert into users values('','name','login','pass');
leaving the first field empty makes it automatically increase it. The beauty is
that you can have 400 people registering at once, and their number gets
assigned as the query is run against the database, no matter what order they hit
it in, the system will take it as they come.
HTH,
Robert
Roger Thomas is quoted as saying on 7/25/2005 5:21 AM:
I am required to write a user registration script that captures the basics like
name, phone number etc etc. I would also have to write to mySQL database a
number that is associated with that user.
At this point of writing, the start of that number is unknown. But the number
will be incremented by 1 after each successfull registration.
Let's say the number starts from 12345.
I am quite new at all these stuff and would like to seek your advise on the
*recommended way* of achieving this. I am thinking along these lines:
a) store that number (12345) in a table
b) a user registers and assign that number to him
c) increment number to 12346
d) process repeats for the next registration
Concern: How do tell mySQL to lock the 'number' table when a new registration
process is about to take place. Is locking the best option here or is/are there
better ways?
Please advise.

[PHP] [PHP4]: Problem with Form not putting Data in Post Request
Hi, I got a slight problem with a Form that doesn't correctly transmits its data correctly under entering some special data. I put together an example to get hold of the problem but so far I do not have a clue why this doesn't work. Be great if someone got an idea. Here is the sample script I put together to see what actually gets transferred when the Form is submitted. File: ftest.php !DOCTYPE HTML PUBLIC -//W3C//DTD HTML 4.0 Transitional//EN html head titleForm Test Page/title META http-equiv=Content-Type content=text/html; charset=iso-8859-1 /head body form action=ftest.php method='post' encoding='text/plain' Enter a text: input name=TheText type=text size=10 maxlength=10input type=submit /form ?php import_request_variables(gPC,FORM); echo Data from last request:br; echo POST:br; print_r ($_POST); echo brGET:br; print_r ($_GET); echo brCookies:br; print_r ($_COOKIE); ? /body /html Pretty simple and straightforward. The statistics page I currently work on requires to enter a Groupname. All but one groupname so far get accepted. The one that does not get accepted is Group including the If I enter this into the form and submit the data doesnt get forwarded into the post data. Even changing the encoding did not work. I triedthat did work strange enough even alone works but as soon something is in between nothing gets into the post-data. Does anybody have an explanation? Maybe I overlooke something. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

would free me from worrying about locking issues. Thanks everybody.

four is 4 times
three is 3 times
two is 2 times
one is 1 times //(it 's better if one is 1 time).

How can I search and count the array? Or better search and count directly using
