Don't know of a way to do it all in one regex. You could do something like
this, though:
$pattern = '/[0-9]{5}(-[0-9]{4})?/';
if((int)$zip && preg_match($pattern,$zip))
{ echo "$zip MATCHES"; }
else
{ echo "$zip doesn't match"; }
Casting $zip to an INTEGER and checking for a TRUE value will eliminate
0, 0-, and anything starting with a letter right off the bat.
Then your regex can handle the rest.

Either this is a bad cut and paste job or this script will never run because
it's full of errors. Either way, if $lid changes, it's because you're

The logic isn't too hard. You're on page X. You show links to other pages from X minus 5 to X plus 5. So if you're on page 15, you show links for pages 10 - 20. Those adjust dynamically based upon the current value of $page.

Subject: [PHP] Another Session Question
Hello all,
I have php ver 4.1.1 running with register_globals() ON on my site. I
am trying to use sessions to maintain state during a visit to the site.
I have read thru the manual, but my mind is still cluttered with
doubts. I understand that use of the $_SESSION global array will
greatly add to the security of the site and will prevent variable
poisoning.
How do I register a session?
The manual (http://www.php.net/manual/en/print/ref.session.php) says
that there are 2 methods:
Example 1. Registering a variable with $_SESSION.
---
Example 4. Registering a variable with register_globals enabled
-
This is a snippet of the code that I am testing:
";
if(!isset($_SESSION['validuser']))
$_SESSION['validuser'] = 0;
else $_SESSION['validuser']++;
}
else{
echo "Please try again later";
}
}
?>
Thanks in advance,
Pushpinder

Re: [PHP] PHP vs. jsp, advice please
Agree 100%. Don't assume that just because you use JSP, or any other language, your program is going to instantly "scale well" and be easy to maintain. You can write crappy, inefficient code in any language. You can also write good programs in most any language if you put the proper planning into it before hand. It all comes down to using the language you know well enough to make your program efficient. If you decide to use JSP, great, I wish you all the best.

Go back and count the quotes again. The original post is correct as far as
quotes go. Yours is not, though, since you have three single quotes in a row
and have thrown in a double quote by itself.
Without color coding, this is all very hard to tell. That's why I prefer to
do it such as:
$sql = "SELECT * FROM db WHERE apple = '{$_POST['foo']}' ";
or, like someone else said, the following is perfectly valid:
$sql = "SELECT * FROM db WHERE apple = '$_POST[foo]' ";
There are way to many methods to do this, though, so just use the one that
makes the most sense to you. I've changed my mind about this a few times in
the past. :)

In addition to what others have said, you don't _have_ to set up the cron job (or any scheduled job) on the same computer as your scripts. If you have a Cable/DSL connection, you could set up a cron job on your own computer to connect to http://www.yourdomain.com/cron.php and run it when you need it.

It's a custom 404 page, IIRC. Your 404 page simply looks at the URL, grabs the last part and forwards (using header(), I imagine) to the appropriate page. Many other uses for it, too. One that's written about on PHP.net is using this to make static HTML pages. You have a URL such as domain.com/1234.html, where that page doesn't exist. Your 404 page looks up product 1234 from the database, writes an HTML page to disk called 1234.html, then redirects back to the page. Now subsequent requests for 1234.html pull up the page just created and do not hit the database at all. To "clear" everything, simply delete all of the .html files and they'll be regenerated as they're needed. I'm sure there are other uses... ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I'm sure you could compile it into PHP somehow, if you wanted to go that route. I can't help you there, though.

Please note the second sentence in this direct quote from the manual:
If id is specified, it will replace the current session id. session_id()
needs to be called before session_start() for that purpose. Depending on the
session handler, not all characters are allowed within the session id. For
example, the file session handler only allows characters in the range a-z,
A-Z and 0-9!

We'll sort out the riff-raff.. :) Seriously, look at their portfolio, call their references, and MAKE them write code. TASK: Create a PHP application that will insert names and dates of birth into a MySQL database. CONDITIONS: Given the PHP Manual, MySQL Manual, Notepad (or similar text editor), and database host, user, and password information. STANDARD: The application will run without errors when complete. The application will accept a first name, last name, and date of birth (in DDMMMYY format) through an HTML form and store the information in a MySQL database. The application will list all current entries in the database in an HTML table after a new row is inserted. Things to look for: 1. Do they program for register_globals ON or OFF? 2. Do they check the setting of magic_quote_gpc? 3. Do they include error checking of form data and queries? 4. Is their program open to cross site scripting or SQL injection attacks? 5. Do they use a DATE type column or VARCHAR column for dates? 6. Do they write valid HTML? 7. How many files do they use to accomplish the task? 8.

With method 2 it seems like your template file would become redundant because every one of them would have to contain the header and footer code. I would use 3 template files, header.php, footer.php, and body_index.php index.php would: 1. PERFORM LOGIC 2. include header 3. include body 4. include footer Then, all you have to do is make new body_XXX.php files for each page on your site and the header/footer content is contained in one place. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

For one little script inserting into it's own little table, yeah, it really doesn't matter. Consider, though, a business making use of this database not only through a PHP script, but through an Access frontend in marketing, some ASP scripts in HR, etc. Now, if you don't enforce the constraints in the database, each and every program must enforce the constraits itself.

What are you actually trying to accomplish here? I could tell you how to
loop through a list in a string and run a query for each number, but I'd
have the horrible feeling that you're using some inefficient method to
accomplish something.
For instance, if you're just trying to select data matching the numbers in
your list, you can do this:
$query = "SELECT * FROM Table WHERE campus_list IN
({$_SESSION['sv_CampusList']})";

Re: [PHP] dealing with arrays
You need to name the elements a little differently. You're on the right
track with making them an array, but if I check the third box, that'll make
$check[0] = 1, and if I put in a name in the first box, that'll make
$name[0] = 'John'... so you have no way of relating the name from "entry
one" to the checkbox in "entry one".
So, the easy fix for this is to supply the key yourself.
Entry One
Entry Two
Now, when that is submitted, only the checked values will be passed in
$check.. so you can do this (assuming POST):
foreach($_POST['check'] as $key => $value)
{
if(empty($_POST['name'][$key]))
{ echo "you didn't supply a name for entry $key"; }
if(empty($_POST['tel'][$key]))
{ echo "you didn't supply a telephone number for entry $key"; }
//process $_POST['name'][$key] and $_POST['tel'][$key]
}
Hope that helps. Sorry for the top post, but OE sucks. :)

The slow down is probably because you're going through HTTP to read the
file. Is there a reason for that? Any way you can cache the file locally so
it's not read through HTTP all of the time?

Ah, I see now.
If you're using a file upload box and submitting that form directly to your
.exe, then there's probably not much you can do.
In order to do this, I think you'll have to "intercept" the file.
When the user submits the file, it goes to a PHP script that copies it
somewhere. Then see if you can make an exec() call to the system and set the
"REMOTE_USER" variable, somehow. I'm not sure on the syntax/possibility of
that, it would depend upon your OS. Then make another exec() call to your
C++ program and send it the path the the file that was already uploaded.
Capture the output and show it to the user or do whatever you normally do.

You could use FIND_IN_SET().
SELECT * FROM properties WHERE FIND_IN_SET('pool',amenities) AND
FIND_IN_SET('spa',amenities) AND ...
It'll still grow as the number of amentities grow, but there's no getting

You should only "connect" once in your script. It's usually in an include

Is register_globals ON or OFF? You shouldn't mix session_register() with
$_SESSION. Just use one other the other, but I recommend just using
$_SESSION.
$_SESSION['var'] = 'some value';
to set a session var, and
if(isset($_SESSION['var']))
to see if a variable is set.
Also, if you have a varible $foobar within a class method that you define as
a session var, you must make it global if you want to access it in other
methods. The same thing for HTTP_SESSION_VARS. I think you're just running
into a scope issue.

You can use this in your query to calculate the age: year(current_date) - year(dob) - (if(dayofyear(dob)>dayofyear(current_date),1,0)) where "dob" is the Date of Birth column in a MySQL DATE format. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

It's discussed on here often. Basically, you use an apache command to FORCE "groups" to be a PHP file. Then the remainder of the URL is available in $_SERVER['REQUEST_URI']. You parse that to determine what group the user is after, retrieve the content, and show it. Search the archives or google for "search friendly urls" and you should get some good tutorials or instructions. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[snip] You should use move_uploaded_file(), which will overwrite the destination file if it exists. It also has the added security that rename() does not in that it will ENSURE the file actually came from an HTTP POST operation. http://us2.php.net/manual/en/function.move-uploaded-file.php ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

You need to use output buffering to capture the output with var_dump. Or you can use print_r(), which will give you a similar output and can be returned to a varible. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

The only difference between print_r() and var_export() produces valid PHP code.
