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)

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 $i started at. However, I would recommend
using a new counter that starts a 0 and is incremented at the end of
your loop.
Alternatively you could do:
print tr
bgcolor='#ff'td$item_1/tdtd$item_2/tdtd$item_4/tdtdcenter$item_5/center/td/tr\n;
if ($i % 8 == 7) {
print trtd colspan='4'/td/tr\n;
}
which would keep them the same color and add a blank row after every
eighth; again adjust $i as necessary to fit.

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

if (count($MyArray) == 1) {
$d = array_shift($MyArray);

$d = $MyArray;

You should be able to through a shell. Try using a shell script to
rename the files, here's something in bash script to get you started:
for x in `ls`; do
good_name=`echo -n ${x}|sed s/\(.*\.[a-zA-Z]*\)/\1/`;
mv ${x} ${good_name};
done
This will find any characters followed by a '.' and any upper or
lowercase letter. This should grab everything except for the newline at
the end and rename the file accordingly. Since I don't have any files
with newlines in their names I didn't test it so it may need a bit of
tweaking.

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.

The important thing to keep in mind here is to use the right tool for the job. If you are parsing an HTML document looking for tags, attributes, etc. I do recommend using domxml/simplexml/some XML parsing tool to get your job done quickly and cleanly. 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

Can PHP handle this or am I better of breaking this down into 12 100mb chunks and processing it? 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].

You could trying writing a script to check the first several bytes of the file for control characters. If the first 1kb is = 20% (randomly pulled from my head) control characters it's a safe bet it is a binary file.

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.

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);

On Tue, 2004-02-17 at 19:25, Richard Gintz wrote:
Using the exact same code, I created 50 objects. It took twice as
long in php5 as it did in the older php4.
From what I remember the speed improvement with objects in PHP 5 was
that they would be passed by reference, which I understand to be the
case. 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:
?php
include_once('Object.php');
include_once('ClassBase.php');
include_once('ClassData.php');
include_once('Class.php');
function getmicrotime() {
list($usec, $sec) = explode(' ', microtime());
return ((float)$usec + (float)$sec);
}
$script_start = getmicrotime();
for ($x = 0; $x 10; $x++)
$a = new Class();
echo 'Script Time: ' . sprintf('%.4f',(getmicrotime() - $script_start))
. \n;
?
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.

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

Re: [PHP] PHP5: Problem concerning multiple inheritance / interfaces
Oops, I left this in my Drafts folder, sorry about that.
On Wed, 2004-02-04 at 20:28, Vivian Steller wrote:
ok my problem in a nutshell: i need multiple inheritance! is there a
solution to fake this functionallity in php5?
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.
i have the following problem:
the goal is to implement my own DomXML implementation based on the existing
DomNode, DomDocument, Dom... Classes.
thus, i implement my classes as follows:
class MyNode extends DomNode {} // that isn't the problem
class MyDocument extends DomDocument {} // would be fine, but...
this would be an easy solution, but there is a logical problem:
if i extend the DomNode (with the methods in MyNode) then -i think-
MyDocument should have those extended methods, too.
so i could write:
class MyDocument extends MyNode {} // problem
but now i'm missing all the nice methods of DomDocument!!
multiple inheritance would solve this problem:
class MyDocument extends MyNode,DomDocument {} // not possible
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.
I'm thinking about the new __call() method implemented as follows:
class MyDocument extends MyNode {
function __call($method, $params) { // fake solution
...
eval(DomDocument::$method($paramsString););
}
}
but with a fake solution like this i wouldn't get all methods with
get_class_methods() and that wouldn't be that nice:)
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,

Instead I am playing with replacing each function call that should throw an exception manually. This has also helped me increase the granularity of my exceptions. Because I generate practically all the code I have that uses system function calls in some way it's not much additional code for me to write. This sounds very interesting. Can you elaborate how and what you actually did for generating the code (what was your input and how did you transform it)? Right now I have a php script that reads in sql code (currently MySQL's semantics) and outputs a series of classes. I can not get into too much detail as I consider it very dear to my process. :) However, I am able to generate a complete class based data abstraction layer from sql code, which is nice. :) I think such a real hierarchy of classes will never exist. That's too much for PHP; none of the developers want to break BC and also follow the KISS credo (which is good, imho). I wonder what will happen to the user base as PHP 5 comes out and later when PHP 6 is in the works. Classes are becoming more popular in php and I have already seen some discussion on implementing a base PHP framework in classes. It seems some people are considering using Java's structure, which I would agree is way to formal for PHP, however hopefully some good middle ground will be found. But it sounds interesting in re-creating the globbered global function table of PHP in a well thought class framework and make it exception-proof. But that would be a step back either if this wrapping would only occur in PHP side - for every PHP function there would need to be called a userland PHP code before. I even don't want to think about the performance implications. But well, since this is effectively what I started with with my System class, there my be needs where this trade off is accecptable (compensating longer execution time with caches and more hardware power/ram/whatever). I don't think an in system solution would be a good idea. I appreciate the PHP developer's respect for functional programming and think it would be a mistake to being integrating an object oriented framework in all of PHP itself. One if the benefits of PHP is its similarity to C. I think for the current issue I will just continue recreating the PHP functions inside an exception-proof class if I don't find a better way. Only creating them on-demand isn't a real problem (at the moment). Let me know how it goes. If you want to merge code and start an impromptu class repository for PHP 5 I would be interested. I have only been playing around with PHP 5 since it is still in beta, I haven't tried converting an entire application over to the new class syntax yet.

Using include literally inserts the contents of the file into your

variables you want to pass as a query string before including the
script:
if ($_SESSION['valores_relativos']) {
echo 'img src=./5_grafico_total.php?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 'img src=./5_grafico_total.php?aVar=aValue';
} else {
$aVar = 'aValue';

over 80 characters to their own lines, and always use the former of the

*always* use the coding standards already in place. The most important

using different coding styles increases or decreases readability,

Someone else says: 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.

Has anyone played around with PHP5 and thought about such issues? 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.

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.

Slightly less resource-efficient, but you don't have to reinvent the

$result = shell_exec(echo '${expr}' | bc);
Both eval and piping to bc via the shell work but open up big security

Re: [PHP] CVS style project system
On Thu, 2004-02-05 at 20:21, [EMAIL PROTECTED] wrote: i have been asked to build a system for a project file space, where a list of users of different groups can start new projects for their group, add files for that project of the group and/or revise current files with different versions. It will be a cvs like system, but i dont think cvs would be apropriate for this, as they want to add titles to the project and comments etc. It will be database in Mysql. I was wondering how i could go about designing this system, and any ways to force people to sync up with the latest versions of the documents. 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 am of the camp that thinks storing entire files in a database is a bad thing. Think of your filesystem as a database optimized for storing files. class new_wheel extends wheel class new_wheel Regards, Adam [1] http://viewcvs.sourceforge.net/ [2] http://cvsgrab.sourceforge.net/ [3] http://www.freebsd.org/projects/cvsweb.html [4] http://www.akhphd.au.dk/~bertho/cvsgraph/ [5] http://www.webdav.org/ -- 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

I continued discussion of this in the php internals list:

What I have found so far is that it is impossible to get exactly what we

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__);
}
}

Re: [PHP] Recommendation on PHP encoder please
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 filename 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.

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[\\[\\{{||

There may not be a simple answer to this, but in general, would it be preferred to do this with 24-hour session variables, or by writing a MySQL record for each visitor with the date and their IP address and tracking their usage count? 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.

I have tried this but its not working.
!eregi(^[0-9a-fA-F]{2}\:[0-9a-fA-F]{2}\:[0-9a-fA-F]{2}\:[0-9a-fA-F]{2}\:[0-9a-fA-F]{2}\:[0-9a-fA-F]{2}$,$_POST['mac'])
so it should match 2 characters 0-9a-fA-F
each block of 2 characters is followed by a : and repreated in 6
blocks.
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
