echo date ("l, F j, Y");
also I want to have it state when the users login in

[PHP] MySQL - setting relationships
In MS Access we specifically set relationships. In MySQL, I have found no documentation regarding setting relationships. Is is that we do not need to set the relationships in MySQl and only matching the Field IDs in respectyive tables is suffecient? Current versions of MySQL do not have ways to constrain foreign keys unless you're using the InnoDB table type. This will change in later versions of MySQL. For the time being, you can still create your database as you otherwise would and perform a join across the tables.

show any relevant code.
That being said...
The error you are seeing (presumably the one you're talking about) is
this
QUERY: INSERT INTO Schools (LongName, Abbreviation) VALUES
('safadssfdfds','afdafsdsf')
Error de MySQL: Duplicate entry '' for key 2

Basically the query is failing because a column in your database must
have unique values for each row and your query doesn't accomplish that.
This is a MySQL database issue and can be solved once you take a look
at your query (which is printed by the script) and the database scheme.

Re: [PHP] Browser Sniffing
I know, it can't be done in PHP. That's not exactly what I'm here
for. I have a client who would like to redirect people to a polite
'upgrade your browser' page whenever people visit his site (which has
been developed in PHP no less). My question here is, how can I make
this so that regardless of what URL someone comes in to, it will
always run the sniffer prior to loading the actual URL they visited?
In other words, whether the visitor comes to the main url
(http://www.site.org), or whether they are going to a specific link
(http://ww.site.org/seethis/), the client would like the sniffer to
check them all.
I know I can stick the whole javascript sniffer into each and every
file, but that's just not efficient. Being that this site was created
in PHP, I can very easily stick an 'include' in each file to include
the javascript piece, however how can I use the results of that
javascript piece inside PHP to then do a Header("Location...") type
thing? Can I even do that considering that javascript normally goes
within the ... section, at which point the page headers
were already sent, and doing a Location redirection within PHP will
only result in an error.
This can be done using PHP, the HTTP_USER_AGENT variable, the
get_browser() function, and a browscap.ini file. Check out:
http://www.php.net/manual/en/function.get-browser.php
Make a script that determines the browser being used which redirects if
necessary. Include this at the top of every page and voila!
Hope that helps,

Re: [PHP] search by keyword
on the search_results page, what happens is:
-i use explode() to break the comma-delimited string down into array
elements, and count() to count the number of array elements
-then i use a for loop to cycle through the list of array elements and
run a sql query to search through a table for any matches to a
particular array element. the for loop looks like
//for loop that cycles through elements in an array, and searching
through a mys
ql table for matches
for($j=0; $j<$count_elements; $j++)
{$sql.="and columnname like '%keywords[$j]%' or columnname2 like
'%keywords[$j]'
or columnname3 like '%keywords[$j]%'...'";}
i think this is technically working, since it's not giving me any
errors, however it basically slows down searches to the point of
unusability.
If you are using MySQL, look into FULL TEXT searches. MySQL 4 also has
a binary mode which is pretty good. Make sure you've indexed your
columns as well.

Re: [PHP] recursive acronym - PHP
Why PHP is a recursive acronym?, I know that before was called Personal Home Page, I now is Hypertext PreProcessor, but why is recursive?, I person told me that it could be wroten as Pre Hypertxt Processor, thanks. PHP stands for "PHP: Hypertext Preprocessor". It's called a recursive acronym because it uses itself in its definition. Another example: GNU, for "GNU's Not Unix".

Re: [PHP] Re: PHP SESSION DURATION.....
Correction: I meant to say: Are session variables stored server-side or client-side like cookies? The session data is stored on the server. The session cookie (if there is one) is stored in the browser. How do I go about making a session last longer that the duration of the browser? Set the expiration on the session cookie so that it's a month from now, using the set_session_cookie_params() function. Also, force the users to accept cookies (somehow). Then change the garbage collection so that it won't trash session data for at least a month. Considering how inefficient all of that is, you might be better off storing the data in a database instead of a session and then storing the database record ID in a cookie in the browser. There are some serious security considerations here but it will get your results and won't rely upon PHP's sessions. Again, this isn't ideal but it's a start...

Re: [PHP] onChange
I have 2 list fields in a form. The second is populated basing on selection in field 1. Can anyone pls tell me how to do this in PHP ? You can't do this with PHP. PHP is server side which means it only reacts after a request has been made to the server (by loading a Web page or submitting a form, for example). For what you're trying to do, you'll need to use JavaScript, which is client side. You can use PHP to help create the JavaScript, though.

Re: [PHP] Extra byte added to PDF streaming file
It appears as though some readers (such as adobe acrobat) can read this file fine yet others (such as the program gv in *NIX) cannot read it. The reason for this is that somehow a hex 0A is added before the inital %PDF-1.2 which marks the start of the PDF file causing some readers to not recognize it as a PDF file. Is there anything in this code which could possibly (always) cause an extra byte (0A) to be added before the real start of the file? And no, the file is not corrupted (I've already tried that) - this only happens when it goes through this script, and not loaded directly as example.com/file.pdf. I've seen cases where extra buffer content gets added to the downloaded file. The problem was fixed by deleting any existing buffer before sending the file to the client. Not sure that will solve the problem but it's worth a shot. Larry -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

It's very easy to use yet powerful (supports grep, works with Xcode, has command line tools, etc). The new version 8 ties into Apache, letting you test PHP scripts in the application.

Although neither is technically a textbook, both are used as textbooks in high school and college classes. For a recommendation without the self-interest, the Thomson and Welling "PHP and MySQL " (Sams) is a very good book (I forget the title, but it is good and thorough).

Second, what you are asking is a Notepad question, it actually has __nothing__ to do with PHP. Third, Notepad is a very bare bones text editor and does not have features like the one you're looking for. Fourth, a great way to see what an application can do is open it and look at the menus. Like File. Like File>Open. Fifth, yes, Notepad can open remote files if you can connect to the remote server from your computer. This is true of any application. Sixth, can __you__ actually connect to your remote server from Windows so that you can open a networked file? Um, I'm guessing not. Seventh, many FTP applications let you set an external text editor. This would let you connect to the server, edit a file in Notepad, and save it, without saving it to your hard drive first. Eighth, many of these answers will be the same for Dreamweaver, although that's a much more sophisticated application. That being said, DW probably has the ability to open and edit remote files. You know what would be a good way to find out for certain? Check out a DW reference or open the application. Ninth, there's is no number nine. Tenth, again, this isn't really a PHP question.

There are a few problems here:

Constants, by their very definition, cannot be redefined (except for magic constants, which is a different thing). Also, constants must be set as scalar values.

Re: [PHP] Object oriented??
Yes of course...but was confused since some says it is so and some says it is not...So thought of asking the pros.. It is. PHP4 had limited support for OOP, though it was quite usable. PHP5 goes further and provides pretty much everything else. See the documentation on php.net for the complete language reference. I guess this is where the OP's confusion stemmed from (Robert said Yes, I said No)! A liberal definition of OO is "An adjective applied to any system or language that supports the use of objects", under which PHP would qualify. But, in strict OO languages, everything must be done using objects. You can't even do a simple "Hello, World" without them (I could be wrong on this, of course). With that understanding PHP would not be OO. So, in short, PHP __supports__ objects but does not __require__ them. There's a good chance that 20 people will chime in now, with their own corrections.

Re: [PHP] Re: and statement
err i mean ... an 'or' statement sry is there an 'and' statement for mysql, when you are doing multiple "where"s? MySQL allows SQL statements that support both AND and OR. With OR, you can often use IN instead. SELECT columns FROM tablename WHERE (condition1) AND (condition2)... All of this is in the MySQL manual, of course. Larry PS Technically speaking, this question would have been more appropriate on a MySQL list (or the PHP-DB list). -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] first letter
if i have for example this variable $name = "John"; how can i echo the first letter only so the result on the browser will be "J" echo $name[0]; You could also use the substr() function. Larry -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] OT Re: [PHP] can I compile php source
While "Yes" may be a technically accurate answer to a question like "Can I ..." or "Can anyone ...", a couple of points must be acknowledged: 1) Such an answer doesn't help the original poster. Period. And the purpose of a resource like this is to help, right? Even a "RTFM" or "search Google" at least gives the user __something__ to work with (and the lesson there being that if they read the manual or search Google, they'll quickly find answers). If your argument for answering "Yes" is that you're teaching the user to ask questions the smart way, then why not answer their intended question AND refer them to the smart questions page? Do you honestly think people are learning __anything__ when you reply with a "Yes"? Moreover... 2) It's commonplace in human discourse to attempt to address the *intent* of a person's question rather than the literal question itself. If you were helping a friend re-shingle a roof and they said "Can you hand me that hammer?", hopefully you would actually hand them the hammer, not say "Yes". They are many colloquialisms in languages--like when someone says "What's up?"--and it's just obstinate not to recognize them as such and respond accordingly. Finally, if you don't agree that "Yes" isn't helpful and that it's an inappropriate answer anyway, how about this: such emails are a waste of resources. It's a waste of the time (.1 nanoseconds or whatever) it took you to write. It's a waste of bandwidth (at a few bits a pop). It's a waste of everyone's time in reading and deleting such emails (another second). And it tends to start a sequence of even longer, off topic threads such as this one. So, seriously, if you don't feel like helping or you don't believe that a message should be posted here because it's off topic or you don't believe that a question was phrased properly, wouldn't it be better for everyone if you just didn't respond? It'd certainly be easier. Oy vay! Larry -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] can I compile php source
Guys, this is trivial. It takes the same effort to provide the answer to whoever this guy was, than to lecture him on how to think. "Teach a person to fish ..." That's a good and true adage and certainly a philosophy to be put forth by this list. But, the question is, does an answer of "Yes" teach a person anything? I truly suspect not. Whereas "Yes, here's how, and by the way you should read this page about how to ask smart questions." teaches a person quite a bit. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] [JOB] Need a Developer for PHP-MySQL Project
The National Coalition for Dialogue and Deliberation (NCDD) is seeking an independent contractor or company to perform some PHP and MySQL Web development work. In simplest terms, the Web site is a MySQL-driven content management system (CMS), written in PHP, running on a Unix/Linux server. The project can be done remotely but must be completed by the end of 2005. A full and descriptive request for proposal can be found at http://www.thataway.org/misc/ncdd_rfp.pdf Questions can be addressed to the contact person named in the RFP or by replying to this email (not to the mailing list).

Re: [PHP] colleges/schools that offer php/web development courses
can you guys give the names of any schools/colleges that have formal programs to teach web development/security applications. I was teaching one online through the University of California at Berkeley. I'm no longer teaching it but my understanding is that they'll be hiring a replacement and the class will be available again. It is a credit-earning course.

Re: [PHP]PHP Syntax Notation
I'm trying to expand my understanding of PHP by looking at some pre- built code modules. I don't fully understand the syntax "$site->Run ();" in the following code. Can someone offer a helpful explanation? Run(); ?> The $site variable is an object, specifically an instance of the CSite class. Run() is a method (i.e., a function) defined within this class, so the statement $site->Run() executes that function. This is basic object oriented stuff which you may not have run across before.

Re: [PHP] setcookie() is not my friend
I'm trying to setcookie('username',$username,15552000) but on
subsequent pages $_COOKIE('username') is always null.
I verified that I'm setting it before any other output is sent to
the browser. I verified that $username does have some valid
contents. I also verified that the browsers I'm testing are set to
allow all cookies. I do have a $username and a $_SESSION
['username'] that contain the same data.
Well, the stupid/obvious question is: are you checking $_COOKIE
('username') like you posted or $_COOKIE['username'], which is
syntactically correct?
Secondarily, have you set your browser to prompt you when a cookie is
sent and, if so, what happens?
Larry
