Try using array_shift[1] for the first few items instead of list:
$a = array_shift($MyArray);
$b = array_shift($MyArray);
$c = array_shift($MyArray);
$MyArray will have the leftovers, you can just assign it if you need a
copy:
$d = $MyArray;
If you only want $d to be an array when there is more than one entry
left do this instead:
if (count($MyArray) == 1) {
$d = array_shift($MyArray);
} else {
$d = $MyArray;
}

$this->$a should be $this->a

You probably want to do:
$bgcolor = (($i % 16) > 7) ? #ff : #ff;
Since $i % 16 will rotate from 0 - 15. This will work assuming $i
starts at 0. If not then you should do:
$bgcolor = ((($i - $x) % 16) > 7) ? #ff : #ff;
Where $x is whatever value $i started at. However, I would recommend
using a new counter that starts a 0 and is incremented at the end of
your loop.
Alternatively you could do:
print "$item_1$item_2$item_4$item_5\n";
if ($i % 8 == 7) {
print "\n";
}
which would keep them the same color and add a blank row after every
eighth; again adjust $i as necessary to fit.

You can typecast values as well, this may be a good way to achieve what
you are looking for:
if ((int)$var != 0) {
// Do Something
}
Also, if you are going to use this variable as an integer later you can
do the following to explicitly convert $var into an integer:
$var = (int)$var;
That should convert "0" into the integer value 0. Also, note the
following:
var_dump(0 == "0"); //bool(true)
var_dump(0 === "0");//bool(false)

The php translation of that would be:

$userBean = $_SESSION["user];

Others have already commented on the OO structure and I agree that this
approach looks sound. I do have a comment about the code you
illustrated. I noticed you are passing the iterator to the
HTMLGenerator on instantiation, then afterwords processing through the
iterator and calling methods on the HTMLGenerator. Since the
HTMLGenerator has a copy of the iterator it could theoretically do this
itself. For example:
$q = new dbObj;
$x = new iterator;
$y = new HTMLGenerator($q)
$y->processIterator($x);
And then create the processIterator method like so:
HTMLGenerator::processIterator($iterator) {
while ($data = $iterator->next()) {
$this->MakeHTML($data);
$this->outputToFile();
}
}
This will logically allow you to do more things with your HTMLGenerator
(like generate HTML that is not tied to the iterator) as well as use
different iterators in the same HTMLGenerator instance, etc. Also, if
the iterator is what is using the dbObj class (to iterate through the
database data) then consider passing it to the iterator instead.

Adam

That's a long expression, try:
!preg_match('/^([0-9a-f]{2}($|:)){6}/i', $_POST['mac']);
This pattern finds 6 matches of a number or letter (the /i means
case-insensitive) followed by either a ':' or the end of the string.

[PHP] Retrieving class names in a static method
I'm looking for a way to find the class name of an object within a
static method. class_name($this) works for instances, but in a static
method $this does not exist. Also, __CLASS__ isn't inheritable so isn't
really a solution for what I am looking for. Has anybody done this
before?
Here's a theoretical example:
class Foo {
function getClassName() {
// ???
}
}
class Bar extends Foo {
}
echo Foo::getClassName(); // returns 'foo'
echo Bar::getClassName(); // returns 'bar'
One sample application of this would be a debugging method in a base
class that is inherited and used in a static method.
TIA,
Adam

This is one of those tricky problems with web applications. If you rely on sessions then they can just delete the cookie and start over. If you use IP address than people can either disconnect and reconnect. Or even worse if someone gets an IP from their isp someone else already used on your site then they won't be able to do even one search. Lastly, If you have them create a 'basic' account so you can track it they can just create as many accounts as they want. Armed with that knowledge I would suggest the following: First of all, forget IP addresses. They are not reliable enough to assume that multiple requests from the same IP are the same person, especially if you are targeting business customers. Using a non-authenticated session is an easy way to solve your problem, however it will be *dead* simple to get around - switch browsers or delete your cookies. If your searches are relevant to each other (the second search uses session information from the first search, etc.) then this may be more useful since the only way around this is to destroy the session, effectively starting over. Lastly, using basic user accounts (just a username, password, and e-mail) would be your best solution. Granted someone can create 50 yahoo accounts and sign up 50 times. However, the cost to them of creating those accounts, maintaining 50 accounts on your site, and having to log-out and back in every 5 searches may be enough to convince them to pay you instead.

The problem here is your approach. PHP can only be used to control the content sent to browsers. Once the browser receives the content PHP is out of the picture until the next reload.

Sorry bout that. Here's another shot at it.
If I understand your goal correctly you want to escape the existing
backslashes that proceed certain special characters (namely
[:alpha:]+*/.|<>()$). That works fine so far, but you want to add the
[ and ] characters to the list I am guessing. Here is one way you could
do it:
$rule = ereg_replace("[[:alpha:]+*/.|<>()$[\[]", "0", $rule);
That turns this:
a\a\+\-\*\[\{\<\|
into this:
a\\a\\+\-\\*\\[\{\\<\\|
However, you will have a problem if there are double escaped characters,
or characters that are escaped but on in your list. I suggest doing
this:
$rule = ereg_replace("", "", $rule);
This turns this:
a\a\+\-\*\\a+\\-\\*\\a\\[\[\{\\{\<\\<\|\\|
into this:
a\\a\\+\\-\\*a+-*a[\\[\\{{\\<<\\||
which should back out nicely when handled by postgres.

On Thu, 2004-02-05 at 08:13, Harry Sufehmi wrote: > So there's a reasonably easy way to decrypt those encoded files then ? (despite > those vendors' claim...) There isn't a program to revert encoded files to their original state, but there is a disassembler[1]. However, assuming your encryption key is a string all one would need is to do strings on the encoded php file to get your encryption key. The real problem you are facing here is security through obscurity is not security. First of all, your method of encrypting these files and decrypting them before serving up pages is just going to slow down your web server. The key is stored in a file somewhere and therefore easily accessible if someone gained access comparable to the web server. Since the key is readily available the data is not really encrypted, just obfuscated. I assume you are not transmitting these pages over the Internet and even within your intranet are using SSL? If not then that is a much bigger security hole. If you are really dedicated to encrypting these files I have a possible suggestion (see below for big caveats!). Continue with your encryption, however do not store the password anywhere on the server. You could either require the password be typed by users to view the pages (and *don't* cache it in any way anywhere!) or write an extension to apache (or whichever web server you use) to request the password when apache starts. It would then securely store it in ram and use it to decrypt pages, similar to how encrypted SSL certificates are handled. This would not be a php based solution, if php were to have access to the password then all that would be required to retrieve it would be the ability to execute custom php on the system by the hacker. You could try writing a php extension that would handle this however you may have a few problems: 1.) Depending on the web server used the php library's lifetime in memory may be shorter than the web server, or there may be multiple copies of the php library in ram. This would require typing the password more than once per web server restart. 2.) You need to make sure it is not possible to access arbitrary parts of php's memory using documented or undocumented php functions, etc. If so a cracker could write a php script to obtain the password. 3.) You would need to disable the dl() function so a custom extension could not be loaded to grab the password, though php.ini could be modified and the web server restarted. Then all the cracker would need to do would be to wait for you to re-type the password. Additionally make sure core dumps are disabled on the server, otherwise forcing the web server to crash could put the password in the core file. You know, after writing all that I realized something else: these are web pages being served. If the attacker has root access to the system what would prevent him from just using lynx to view the pages directly form the web server? SSL won't stop him/her and usernames and passwords will most likely be available if you use web based authentication. Your best method would be to require the password be typed every time a page is viewed, which has its own set of problems. Hopefully this gives you something to think about.

The answer you are looking for is no. The solution you are looking for is to have an interface from the application on the powerful system doing these calculations to the web server running php. This could be as complicated as an extension to the application doing all this processing, or as simple as an nfs share with some flat files on it. If you are going to put php on the system doing all this processing, why not put apache as well? If it's a security issue you could use squid as a proxy or even have a php script on a public web server access the php running on apache off the secondary server as your integration. You could use ssh to access a cli php script on the secondary server through a php/cgi/etc. "gateway" on your public web server as well.

Let me know thanks. I know you don't want to hear someone say use cvs so... Use viewcvs[1], or write your own version of it. You can put a database behind it, add descriptions to projects and/or folders to your database, whatever you want on top of cvs. You can even use cvsgrab[2] to download a repository from a viewcvs site. There is also cvsweb[3], if you think perl is better than python. If you need to significantly extend the functionality of these possible solutions and you still want to hack out some PHP code then use these as a base for designing whatever you are looking for. As a side note, cvsgraph[4] integrates nicely with viewcvs, and if you do use viewcvs check out the querycvs script. The points I am trying to impress are: 1.) Writing your own version of cvs in PHP is a bigger deal than you likely realize. Even if you do not need every single possible feature of cvs your project will probably grow and you may some day. 2.) The rcs format does a good job of maintaining version control and if you use cvs you get all of its stability, future improvements, etc. 3.) There is a long history behind cvs. It has accumulated a large amount of supporting applications, helper scripts, mailing lists (of which I am on btw), etc. In short an entire community. It would be better for us all if you would join in and help yourself. 4.) Short of using webdav[5] as well as basic HTTP it is a poor usability decision to design a file based revision control system with its only interface being via HTTP. What if people want to download entire directories, etc. You can make direct cvs access an afterthought, but still a possibility. 5.)

I have the same problem:
http://marc.theaimsgroup.com/?l=php-general&m=107575408628272&w=2
I continued discussion of this in the php internals list:
http://lists.php.net/article.php?group=php.internals&article=7520
What I have found so far is that it is impossible to get exactly what we
are looking for in php4. When I get a moment again I want to renew the
discussion on the internals list and see if I can't get $this to be a
reference to a static instance of a class within static methods.
*crosses fingers*
Here is some sample code of what I use to get around this bug. It's
leaky and imperfect, but it is inheritable. Also, other than changing
the function name you can simply copy and paste the code into inherited
classes. Also, while the extra parameter is there you would never call
the function with it in your code so the implementation is fairly clean.
class Foo {
function someFunc($class_name) {
return $class_name;
}
}
class Bar extends Foo {
function someFunc($class_name = NULL) {
return parent::someFunc(isset($class_name) ? $class_name : __CLASS__);
}
}
If you find a better solution *please* let me know.

Try this:
$parent_account = 'parent_name';
$ldap_results = array('account1','account2','parent_name');
$results = array_diff($ldap_results, array($parent_account));
$results will now have only account1 and account2.

This is not an answer, but it is a solution. I don't ever rely on
include_once. If someone else uses my include files they may not use
include_once. Instead I use the old C/C++ trick of defines:
I use the following structure for creating unique constants to prevent
collisions:
{projectname}_{classname}( include ? _INC:)
A global class outside my projects:
_CLASS_NAME
The class FooBar in my Rule The World project:
RULE_THE_WORLD_FOO_BAR
The config include in my Rule The World project:
RULE_THE_WORLD_CONFIG_INC

It sounds like you may want to set the page to not be cached. Here's
what I use to prevent pages from being cached:
function noCacheHeaders() {
header('Expires: Tue, 1 Jan 1980 12:00:00 GMT');
header('Last-Modified: ' . gmdate('D, d M Y H:i:s') . ' GMT');
header('Cache-Control: no-store, no-cache, must-revalidate,
post-check=0, pre-check=0, no-transform');
header('Pragma: no-cache');
}
This should prevent proxies, browsers, etc from caching your pages.

Both eval and piping to bc via the shell work but open up big security
holes if you are not careful. If you have bcmath or gmp enabled in php

Careful with that. If someone were to stumble upon your list.php script
they would be able to see your php code. You would probably be better
off having a local copy of that file.

From what I understand this thread is about including a php script from a different server over http. In this case the php code will be viewable if you open it via a web browser. If you know of a way to include a file remotely with php, but not browse to it, please let me know. Presumably you could use apache to restrict access to the file by ip, however that can still be subverted by a man in the middle attack.

If you do not see 'source' then what are you including? For example the
following script could be included remotely:
EOF;
?>
If you were able to do include the above source with:
include("http://somewhere.com/file.php?number=123";);
You could include and see php code. Not the original but something that
is still useful. include() includes php code, if you can include a file
from a remote source you can view it with a browser. What you say is
true:
"See the source? vulnerable. See the results? not vulnerable."
Of course if you can not see it you also can not include it remotely.
As a side note it is safer to put includes outside the web path. An
overflow or some other bug may be found that would bypass processing of
.php files (or a different bug could be exploited to write a .htaccess
file in that directory). If you have the option to move includes to a
different directory it is more secure.

Where are these variables coming from? The action in your form should
be a url that points to the script you want to process the form. In
that script you access the form variables by $_POST['variable_name'].

This is the traditional method:
// Open input file
$fh = fopen('some_file', 'rb');
// Read header
$header_data = fread($fh, 224);
// Open header output file
$ofh = fopen('some_other_file', 'wb');
// Write header
fwrite($ofh, $header_data);
// Get rest of file
do {
$data = fread($fh, 8192);
if (strlen($data) == 0) {
break;
}
$contents .= $data;
} while (true);
fclose($fh);
If you know you want the entire file, you can always use
file_get_contents. It may behoove you to check the file size first
before reading it entirely into memory:
if (filesize('some_file') <= 1048576) {
$data = file_get_contents('some_file');
$header_data = substr($data, 0, 224);
$data = substr($data, 223);
}

Technically the header function sends an HTTP reply to the client
(browser) with your Location header in the response. The client then
initiates a second HTTP request with the new URL. I remember reading
that apache[1] will look at Location: headers and if it can handle the
request it will process it and pass the output of the Location's URL to
the browser. Regardless, the content will be cached by search engines
but the original URL used to initiate the process will be associated
with the content. To have the redirected URL remembered you need to
pass a 301 Permanent Redirect status instead.

I have been thinking about this myself. When exceptions come they will
be interesting. I almost went down the path you are considering but
decided that I would likely end up with an object hierarchy of the
system calls available in PHP. This is something I very much did not
want to deal with. I also played with creating wrapper functions that
are designed to test for a specific indication of failure (returns
false, returns null, etc.). The problem there is the error reporting
must become more technical ("ERROR: function mysql_query returned
NULL"), or more useless ("a function returned an error"). Plus, code
that uses this is harder to read. Ultimately I decided to wrap my
necessary function calls in error checking wherever they are in my
files. This gives me more granularity in the application of the error
at the cost of some code bloat. It's not an optimal solution but I have
found I use little functions calls in the first place that would
generate an exception in return (memory errors are handled by PHP so
it's only functions that have system calls). This has actually forced
me into creating libraries for what I use and abstracting out system
interfaces anyways. Also, I have started using code generation for
handling the data side.
Ultimately I think it would be nice to have an object hierarchy of the
function calls in php. However I don't see php supporting it natively
and PEAR is still trying to sort itself out. Being a 'third party'
project it is too much for one person but would be quite useful. Maybe
when php5 becomes more popular we can all band together and standardize
this.

No, with sessions there will essentially be multiple values for the variables, one for each session.

You can write an admin interface to manage adding the rows to your tables if you don't want to do it manually.

I'm anal about code formatting. I always use parens with no space
before a function call, put a space before parens for builtin words (if,
while, etc), don't indent case phrases, move multiple arguments that go
over 80 characters to their own lines, and always use the former of the
above methods. Of course, if I am modifying someone else's code I
*always* use the coding standards already in place. The most important
thing is to be consistent. Everybody has their own preference about how
using different coding styles increases or decreases readability,
however I think what really improves readability is commenting, not
coding style.

Heh, what if I use print('')? :P
Actually, I use echo(''), even though using single quotes doesn't give

I enjoy using echo, it's like a rebellion against printf.

Having a function to undo magic quotes can be very useful if you

For storing user status use whatever fits your application best. I save an instance of my user class in the session and use it to check if I have a logged in user. If it is set then that is the user, if not then the session is not logged in. To beef up security I use a combination of the session id (cookies only) and set an additional cookie that contains a random sequence. This acts like an initialization vector does in cryptography.

A good place to start reading about functions is in the php manual[1].
In short, functions are blocks of code that achieve a particular
purpose, or function. Arguments[2] are used with functions to pass
information, or variables, to these blocks of code. Generally the
arguments are used or manipulated by the function. Functions may pass
back, or return[3], information as well. Here are some sample
functions, function calls, and output for context. Steps are separated
as much as possible for clarity:
// No arguments
function echoHelloWorld() {
echo "Hello World\n";
}
echoHelloWorld(); // Output: Hello World
// Has arguments, uses data.
function printPlusOne($number) {
$number = $number + 1;
echo $number . "\n";
}
printPlusOne(2); // Output: 3
// Has arguments, manipulates and returns data.
function doubleNumber($number) {
$number = $number * 2;
return $number;
}
$value = doubleNumber(10);
echo $value . "\n"; // Output: 20

It sounds like you would want to check out association and
aggregation[1]. Though aggregation looks mighty attractive, I doubt it
will work in your situation since you do not get the constructor, and
therefore the underlying reference to the DOM library is missing. See
below for a possible solution.

Neither prototype nor multiple inheritance is directly supported in
php. The best option to achieve what you want would be to define your
new class layer (MyNode, MyDocument, etc.) as inheriting from their
respective classes (ex. MyDocument extends MyNode). Then within each
class definition hold the respective DOM class in a property:
class MyNode {
var $dom_node;
function MyNode($param) {
$this->dom_node = new DomNode($param);
}
}
You then will need to write stub methods to implement each method in the
DOM class for your class. You can then manually override any DOM method
as well as extend the class in your own manner. An important note: You
*never* want to access the property for the DOM instance directly, if
you are using PHP 5 you *must* make this property private. This is a
fair amount of code bloat but afaik the only way you can conform php4 to
your design. See below for more solutions relating to PHP 5.

The Reflection API[2] in PHP 5 can help you here. I'm hoping to play
with it sometime and see if it can be used to fake prototypes by
allowing modification of the method and property spaces. That *would*
be nice. :) Even if it does not, you can still use it to look up and
call methods from other classes.
> Can Interfaces help me?
They may, but interfaces will not implement the code themselves.
Without prototypes you will need to either write accessor code to the
DOM methods in a function outside your classes and a wrapper for each
object, or copy and paste the code manually to implement the additional
Node sub-class functions across all other sub-classes. I would
recommend leaving interfaces out of this as they will provide
unnecessary structure and rigidity to your code. Implement only the
constraints you absolutely need.
Hopefully this gives you something to think on. As I am still working
out the possibilities in php myself I would appreciate any findings you
have back here.
Hope this helps,

So, can you tell me, how to avoid this? When you request (get) a file using the ftp command you send a RETR command to the ftp server indicating which file you want to retrieve. I'm not 100% sure what is going on since there is no code in your post, but it looks like the RETR command is disabled on the ftp server. This means you will not be able to download files. Try retrieving the file manually using your favorite ftp client and see what happens. If you can post the code you are using we may be able to help better. -- Adam Bregenzer [EMAIL PROTECTED] http://adam.bregenzer.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Using include literally inserts the contents of the file into your
code. One way to achieve what you are looking for is to set the
variables you want to pass as a query string before including the
script:
if ($_SESSION['valores_relativos']) {
echo '';
} else {
$_GET[aVar] = 'aValue';
include ("./5_grafico_total.php");
}
If you rely on register globals you would want to set the variables
directly like so:
if ($_SESSION['valores_relativos']) {
echo '';
} else {
$aVar = 'aValue';
include ("./5_grafico_total.php");
}

First of all, you are flipping your variables:
while ($singleauthor = each($tempauthors))
Secondly, check the manual to see what each() returns[1]. It returns an
array with the key and value of the result in it. If you want to use
each() then you need to evaluate $singleauthor as $singleauthor[0] or
$singleauthor['value'] to get its value. Another way to do this that
would be closer to what foreach does would be:
while (list($key, $singleauthor) = each($tempauthors))
This will assign the key to $key and the value you are looking for to
$singleauthor.

Careful, that will eat your array as well. When the while loop finishes
you won't have any pieces of pie left!
IE:
$applePie = array(1,2,3,4,5,6,7,8);
while ($pieceOfPie = array_shift($applePie)) {
echo $pieceOfPie; // want some pie?
}
// Both of these are now true:
$applePie == array();
$applePie != array(1,2,3,4,5,6,7,8);

This is a javascript question not a PHP question, but how about:
selectedAudits = 0;
if (myMultiSelect.length) {
for(i = 0; i < myMultiSelect.length; i++)
if (myMultiSelect[i].checked) selectedAudits++;

Try passing an object to a function, modifying it, then returning it and echoing the result. I was surprised however to hear that you found PHP 5 to be slower, I would be interested in any benchmarking results you have. I also decided to do a quick test. I wanted to test some decent sized classes so I used some I have written already. Each class inherits from the one above it (names have been changed to protect the innocent), therefore Class is a sub-class of ClassData, etc. up to Object. Here is the wc output for the class files: 43 200 1355 Object.php 190 533 5311 ClassBase.php 428 1554 15648 ClassData.php 481 1274 18831 Class.php 1142 3561 41145 total Here is the script I tested with: I tried to measure only the execution time of creating 100,000 objects as accurately as possible. Creating them in an array would have been interesting as well, but rather memory intensive, so I decided against it. Another note is that I did run PHP 5 in cli mode only. I installed both copies of php as well as apache2 and Turck MM Cache through emerge on a Gentoo system. They were compiled from source but I did not change their optimizations from the default. Since this is a testing box PHP is installed with pretty much everything. Disclaimers aside, below is what I found. PHP 4.3.4 and apache2: Script Time: 16.0964 Script Time: 16.0322 Script Time: 16.0289 Script Time: 16.0710 Script Time: 16.0306 Average: 16.0518 PHP 4.3.4 and apache2 with Turck MMCache v2.4.6: Script Time: 15.1848 Script Time: 15.2146 Script Time: 15.2527 Script Time: 15.2354 Script Time: 15.2507 Average: 15.2276 PHP 5.0.0RC1-dev (cli): Script Time: 15.2346 Script Time: 15.2254 Script Time: 15.2538 Script Time: 15.2414 Script Time: 15.2554 Average: 15.2421 PHP 4 is a bit slower than PHP 5, however with an optimizer it comes to be about the same, maybe a touch faster. If/when a PHP 5 optimizer comes out this may change some. I hope to run more benchmarks as I have time. Also, PHP 5 is still in Beta, and this is not even the latest version.

If the script can be read (the "r" permission) it can be run through the php cli like you are doing in cron. If the cron command you have is running under your username, and the script does not need to be viewable by the web server, you can set the permissions to 600, which would be -rw---. This will allow you as the user to read (as well as execute through php) and write to the file and not let anyone else (besides root of course) to do anything with it. Technically, if an executable can be read it can be executed. If it's a binary it can be copied by a user and the copy can be run, if it's a script it can be passed to an interpreter and run.

However, if you have a very specific need to extract some text from a string then you can probably get away with regular expressions. The big catch with regexp is that it has a very low reuse value. Generally regexps are difficult to read and rarely will you just copy and pate a regular expression from one piece of code to another. If your regexp is growing beyond one line and is taking a long time to process then it is time to move on. Additionally, regular expressions are not good at providing context. It just so happens that HTML documents are just text documents so if you can parse the text to get what you need great. However, if you want to move through the elements and attributes, you want something more powerful, like XPath or XQuery. (ie. you want to find the third fieldset child of the body element that has an attribute set to "foo") As a side note, that article has a link to a similar one that lists a regexp based XML parser as the only PHP solution. :) -- Adam Bregenzer [EMAIL PROTECTED] http://adam.bregenzer.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

You need to look up how to use explode[1], my guess is you don't want to
use it at all here. In fact, implode[2] may be exactly what you are
looking for.

Re: [PHP] Parsing large log files with PHP

PHP has a very rich set of functions to read in files, it all depends on what you are doing with the log file and how you read it in. For example, if you use the file[1] function it will read the entire log file into memory, that is probably a bad thing for what you are trying to do. However, if you need to access many different parts of the file frequently and you have the ram go for it. On the other side of the spectrum are the C-like functions: fopen[2], fgets[3], fread[4], fclose[5], et. al. These will give you a high level of control over how much of the file you read in at a time. Lastly, the stream[6] functions may be a good middle ground for you.

You can either use the date functions or regexps, I would recommend the
date functions, they may be a bit slower but they are more flexible and
easier to read:
$timestamp = strtotime('2004-02-24 07:57:59');
$date = date('d-m-Y', $timestamp);
Also, it would be best to try and get the date in a timestamp instead of
a formatted string, check if your database can do this. If so then you
can skip the strtotime step above. If you are using MySQL and the date
field is one of the date formats (ie. not char/varchar) take a look at
MySQL's date formatting functions[1].

Adam

How about is_writable[1]? Just to throw it out there. My favorite, non-portable, hackish solution is `touch $dir`; :) [1] http://www.php.net/is_writable -- Adam Bregenzer [EMAIL PROTECTED] http://adam.bregenzer.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Make an array containing the characters/numbers/whatever you want to be
selected at random then pick from it using a random integer generated
from mt_rand[1] and echo your selection. If you have PHP < 4.2.0 you
will also need to use mt_srand[2].
$field = array('a','b');
$field_max = count($field) - 1;
echo $field[mt_rand(0, $field_max)];

Verifying you have unique records as well as generating the prize information are part of the tasks you need to solve in writing the application. You may want to store the information in a database and use it to verify the uniqueness of the keys, also you can then easily batch process the application so it can be stopped and started. > As was mentioned I don't want this script to take ten years to output > 2 million records and I wasn't sure if there are size constraints with > comma delimited files. I would recommend splitting the application into pieces, first generate the keys, then assign the prizes, this way you have more control. Also, I would run this through the cli, not as a web page. As for how long it will take, that's anybody's guess and greatly depends on the speed of the system you run it on. > Hope this clarifies things a little more.
