Use this regex:
if(preg_match('/[[:punct:]]/', $_POST['username']) !== 0) {
// string contains other characters, write the code
}
The POSIX class [:punct:] means matches any punctuation and symbols in your
string and that includes [!#$%'()*+,\-./:;=?@[\\\]^_`{|}~]

Or... just use:

// string contains other characters, write the code
}
You can see this regex in action here: http://regexpal.com/?flags=regex=
^%5BA-Za-z0-9%5D%2B%24input=myusername01
If you put anything different of A-Za-z0-9 the regex will not match.

As an alternative to the regular expression approaches already provided by
others, you could also use ctype_alnum():
if (ctyp_alnum($_POST['username'])) {
//username contains only letters and numbers
} else {
//username contains characters other than letters and numbers
} //if-else
Docs: http://us3.php.net/manual/en/function.ctype-alnum.php
As a bonus, this will likely be quite a bit quicker than the regex-based
approaches. That said, you'd have to be making many calls (e.g., inside a
loop) for the difference to reach the point of being noticeable. For
something like a one-time validation on page-load, use whichever you find
most comfortable.
In your original question, you also mentioned looping through a variable
to check for non-alphanumeric characters. The regex approach or the
approach I outlined above is much better in this case, but as a learning
exercise, you could do the looping like this:
$validCharacters = array('a', 'e', 'i', 'o', 'u');
for ($i = 0; $i count($_POST['username']); $i++) {
if (in_array($_POST['username'][$i], $validCharacters)) {
echo 'Pass!';
} else {
echo 'Fail!';
} //if-else
} //for i
The key thing to note there is that you can treat the string like it's an
array to loop through it. For more information about this, go here:
http://us2.php.net/manual/en/language.types.string.php
and search the page for the phrase String access and modification by
character.

On 9/22/11 13:38, Eric eric_justin_al...@cfl.rr.com wrote:
So is $_POST[username][0] appropriate or does that only work
with normal variables?
As far as this sort of manipulation goes, $_POST is just like any other
variable. Referencing the 0th element of any string will give you the
first character, if there is one. (If there isn't one, you'll generate a
PHP warning or notice for trying to read out-of-bounds.)
and would this be valid,
$i = 0;
while($_POST[username][$i] != \0)
It looks like you're trying to treat the string as a C-style string. That
won't work in PHP because PHP's strings are not null-terminated. Thus,
this will lead to an infinite loop with any strings that don't happen to
have the null character somewhere within (and most strings won't).
{
if($_POST[username][$i] == . || $_POST[username][$i] == ..)
This line is not wrong per-se, but nor does it entirely make sense. When
you access a string as an array, each element contains one character.
Here, you're checking whether each character in turn is a period (fine) or
two periods (makes no sense, since one character cannot represent two
period characters). What you'd probably want to do is simply remove the
second condition, since a check for one period will work just as well if
the name contains two periods. That is:
if($_POST[username][$i] == .)
Incidentally, another tip: when comparing against a constant, as you are
in both your while() and your if(), place the constant on the left side if
the expression rather than the right. That is, write the previous if()
like this:
if ('.' == $_POST['username'])
It might look a little funny, but I assure you, someday, it'll save you a
bunch of frustrating debugging time. The reason is that if you mistype the
'==' as '=', you'll do an assignment, the value of which is then returned.
This has the net effect of 1) quietly changing your variable's value, and
2) making the overall expression always evaluate to true, sending you into
the the true part of the conditional branch, well, unconditionally.

well i think you may be in the right direction, however, id be interested to
see what others on the list think about this particular approach.
personally, i wouldnt store an image in the session.. but i would certainly
provision a temporary directory inside the webroot where you could put these
images.
perhaps if the images are tied to sessions, throw cleanup in a custom
session cleanup cron, or queue the images for deletion when the user logs
out. seems to me like the session is an area of abuse in many php apps ive
seen. even though the standard store is file based, i would still recommend
a separate store for images.
public function render_image()
{
$my_img = imagecreate( 200, 80 );
$background = imagecolorallocate( $my_img, 0, 0, 255 );
$text_colour = imagecolorallocate( $my_img, 255, 255, 0 );
$line_colour = imagecolorallocate( $my_img, 128, 255, 0 );
imagestring( $my_img, 4, 30, 25, Test Image, $text_colour

imagesetthickness ( $my_img, 5 );
imageline( $my_img, 30, 45, 165, 45, $line_colour );
ob_start();

header('Content-Length: ' . strlen($my_img));
imagepng( $my_img );
$final_image_data = ob_get_contents();
ob_end_clean();
imagecolordeallocate( $line_color );
imagecolordeallocate( $text_color );
imagecolordeallocate( $background );
imagedestroy( $my_img );
echo
'data:image/png;base64,'.base64_encode($final_image_data);
}
img src=?php $my_lopa-render_image(); ? width=200 height=80
i dunno, why not just have something a bit simpler, where you generate an
image and store it to disk. the function could return the path where the
image was saved. then when the browser loads that resource php doesnt even

not sure on whether you would pass in the location or if you would have
internal logic cook up the path, but im sure you could determine that based
on the rest of the code .. lets suppose your class computes it internally,
something like
?php
class LOPA
{
private function get_temp_path()
{
// some session specific logic to cook up a temporary path
// something relative to the web root ...
}
public function render_image()
{
$my_img = imagecreate( 200, 80 );
$background = imagecolorallocate( $my_img, 0, 0, 255 );
$text_colour = imagecolorallocate( $my_img, 255, 255, 0 );
$line_colour = imagecolorallocate( $my_img, 128, 255, 0 );
imagestring( $my_img, 4, 30, 25, Test Image, $text_colour);
imagesetthickness ( $my_img, 5 );
imageline( $my_img, 30, 45, 165, 45, $line_colour );
// now saving to a temp location inside the webroot
$temp_path = $this-get_temp_path();
imagepng( $my_img, $temp_path );
imagecolordeallocate( $line_color );
imagecolordeallocate( $text_color );
imagecolordeallocate( $background );
imagedestroy( $my_img );
// returning path to temp location
return $temp_path;
}
}

I had a similar issue in generating a badge based upon various stats.
I found that there were many individuals who shared the same stats, so
the badge was the same. Even more advanced users often shared stats.
So, rather than creating an image per individual, I based the name of
the image on $md5BadgeData = md5(serialize($badgeData)).
So, main page loads and gathers the stats for person.
If the badge doesn't exist, then creates the PNG file.
Write out the HTML using img src=./badges/{$md5BadgeData}.png /
If a user's stats change, they'll have a new badge. Sure, there will
be orphaned badges, but they are tiny little things and I don't have
gazillion users.

Your approach with the class should show as src= on your rendered web page
since the output from the function is binary meant for the browser, read:
not meant as content for an HTML attribute.
The later however is fine, since its text which references a php page. What
happens when that is sent to the browser is it invokes images/gdtest.php on
your server, which outputs the binary directly to the browser.
If you want to use the class, you should do as your second example for the
tag itself, then inside of images/gdtest.php instantiate the class and call
the method.
gdtest.php
?php
$oImgRenderer = new LOPA(); // or whatever your class is called
$oImgRenderer-render_image();

well i think you may be in the right direction, however, id be interested to
see what others on the list think about this particular approach.
personally, i wouldnt store an image in the session.. but i would certainly
provision a temporary directory inside the webroot where you could put these
images.
perhaps if the images are tied to sessions, throw cleanup in a custom
session cleanup cron, or queue the images for deletion when the user logs
out. seems to me like the session is an area of abuse in many php apps ive
seen. even though the standard store is file based, i would still recommend
a separate store for images.

$my_img = imagecreate( 200, 80 );
$background = imagecolorallocate( $my_img, 0, 0, 255 );

i dunno, why not just have something a bit simpler, where you generate an
image and store it to disk. the function could return the path where the
image was saved. then when the browser loads that resource php doesnt even
fire up, the webserver just sends back the image directly.
not sure on whether you would pass in the location or if you would have
internal logic cook up the path, but im sure you could determine that based
on the rest of the code .. lets suppose your class computes it internally,
something like
?php
class LOPA
{
private function get_temp_path()
{
// some session specific logic to cook up a temporary path
// something relative to the web root ...

{
$my_img = imagecreate( 200, 80 );
$background = imagecolorallocate( $my_img, 0, 0, 255 );
$text_colour = imagecolorallocate( $my_img, 255, 255, 0 );
$line_colour = imagecolorallocate( $my_img, 128, 255, 0 );
imagestring( $my_img, 4, 30, 25, Test Image, $text_colour);
imagesetthickness ( $my_img, 5 );
imageline( $my_img, 30, 45, 165, 45, $line_colour );

$temp_path = $this-get_temp_path();
imagepng( $my_img, $temp_path );
imagecolordeallocate( $line_color );
imagecolordeallocate( $text_color );
imagecolordeallocate( $background );
imagedestroy( $my_img );
// returning path to temp location
return $temp_path;

Re: [PHP] How can I detect an exception without using try/catch?
a POSSIBLE work round. see if u can use http://in2.php.net/manual/en/function.error-get-last.php or http://in2.php.net/manual/en/reserved.variables.phperrormsg.php but they are not working as expected with xdebug. use them in the __destruct function to check for an uncaught exception alternatively.. this approach is NOT RECOMMENDED. use it only if u run out of options keep the destructor empty. catch the exception and call a function to perform destruction and then unset the object. at the end of script, check if the object is set, call the function to perform destruction.

Re: [PHP] How can I detect an exception without using try/catch?
What would be nice is a function like get_current_exception() that
would either return the current exception object, or return false
if there is no exception.
I guess the try catch pair works like this:
you try to run a part of script which you know it could be under errors

Re: [PHP] How can I detect an exception without using try/catch?
Ok, the details of the problem obviously aren't being understood.
Let's assume that I explained it poorly and I'll try again. Take the
following code (It's complete, cut/paste to see what happens.):
?php
class running {
private $running;
public function __construct() {
$this-running = true;
}
public function stop() {
$this-running = false;
}
public function __destruct() {
if ($this-running) {
throw new exception('I have not stopped running yet!');
}
}
}
function fail_horribly() {
throw new exception('This is the real error that I want a stack trace from');
}
function do_that_thing() {
$running = new running();
fail_horribly();
$running-stop();
}
try {
do_that_thing();
}
catch (exception $e) {
echo $e-getMessage();
}
?
While putting this together, I discovered lots of interesting
behaviour. Depending on exactly where I put the try/catch, there are
different things that happen and different errors that occur. It's
kinda interesting.
The thing is, that none of those errors is the result that I _want_
which is to ignore the fact that $running was unset and just report
the error that started everything going wrong.
If I could put my fictional function (get_current_exception()) in the
__destruct() method, I could detect that an exception was already in
progress and avoid throwing another one.

The best way
to do what you want to do is probably to do the work

can create a hidden input with a specified id,

dhtml via
javascript to modify the input and insert the value
into
the value
field of the hidden input. Then it will get sent to the
server when
the user hits the post button.
However,
since you should be validating any user input server
side,
you'll need
to validate that the variable is accurate - might as
well just do
the count with php server side.
Thanks Michael I
was kind of moving in the right direction as
far as the
hidden input goes, going to have to google on how to
do it with the
dhtml and all like you suggested.
Look at the various DOM
functions - IE for
input type=hidden
name=wordcount id=hiddenStudd value=
you coud do in your js:
var myHidden =
document.getElementById('hiddenStuff');
myHidden.setAttribute('value',$yourvalue);
Thought I would go ahead and post a bit more on this,
so here is my wordcount little function on the textarea of
the form:
textarea name=Comments
cols=55 rows=5 wrap=hard
onKeyDown=wordCounter(this.form.Comments,this.form.remLen,
300);
onKeyUp=wordCounter(this.form.Comments,this.form.remLen,
300);?php if (isset($_SESSION['Comments'])) {echo
$_SESSION['Comments'];}
?/textareabrLetters to the Editor are
limited to 300 words or less.brWords remaining:
input type=box readonly name=remLen size=3
value=300
So I was thinking I should be able to pass that again
to the next page which is the emailform.php page that is
taking all the id= and printing them to an email
should be able to reuse that function right?
input type=hidden id=words value=
onSubmit=return
wordCounter(this.form.Comments,this.form.remLen);
or do I need to define the variable? think I'm
starting to confuse myself lol
You don't want the onSubmit in the the hidden input.
I'm not a javascript guru - but I believe you can have the
form onSubmit do the word count and insert it into the input
field before the actual submit happens, I've never tried
having an onsubmit function alter a value field though.
I would change the textarea to have an id=Comments field
and the remLen input to have an id=remLen field to make it
easy to find via getElementById (as id attributes have to be
unique), count the words and set them to a variable that
then gets put into the hidden input before whatever function
you run on the submit type onSubmit returns true.
not tested - but something like this:
function countTheWords() {
var comment =
$document.getElementById('Comments');
var remLen =
$document.getElementById('remLen').value;
var count =
wordCounter

Look at the various DOM functions - IE for

you coud do in your js:

myHidden.setAttribute('value',$yourvalue);

You don't want the onSubmit in the the hidden input.
I'm not a javascript guru - but I believe you can have the form onSubmit
do the word count and insert it into the input field before the actual
submit happens, I've never tried having an onsubmit function alter a
value field though.
I would change the textarea to have an id=Comments field and the
remLen input to have an id=remLen field to make it easy to find via
getElementById (as id attributes have to be unique), count the words and
set them to a variable that then gets put into the hidden input before
whatever function you run on the submit type onSubmit returns true.
not tested - but something like this:
function countTheWords() {
var comment = $document.getElementById('Comments');
var remLen = $document.getElementById('remLen').value;
var count = wordCounter($comment,$remLen);
var myHidden = document.getElementById('words');
myHidden.setAttribute('value',$count);
}
Then in whatever function you run in the form onSumbit have it run the
countTheWords() function before it exits.

Re: [PHP] How can I echo a javascript var in an email subject line? Possible? (Yes!)
For me its very easy to pass php values to the client:
echo _var($value,'name');
But the best part is taking control of what your client sees from the
server-side:
C('#info')-show(); // now you see it
...
C('#info')-hide(); // now you don't!

Re: [PHP] How can I use a function's default arguments but change one of the end ones in the list?
2009/2/6 Daevid Vincent dae...@daevid.com
Is there a way to use the default values of a function without
specifying every single one until the parameter you want to modify in
PHP5 ?
I don't see it here, but feel this would be very useful indeed.
http://www.php.net/manual/en/functions.arguments.php
So given a function that takes seven parameters, I want to change one of
them and leave the other defaults alone...
?php
function SQL_QUERY($sql, $parameters = null, $showSQL = false,
$showErrors = true, $execute = true, $noHTML = false, $profile = 0)
{
var_dump($sql, $parameters, $showSQL, $showErrors, $execute,
$noHTML,
$profile);
}
?
pre
?php SQL_QUERY('SELECT * FROM foo WHERE bar = ?'); ?
/pre
hr
pre
?php SQL_QUERY('SELECT * FROM foo WHERE bar = ?', array('beep'),
true); ?
/pre
hr
pre
?php SQL_QUERY('SELECT * FROM foo WHERE bar = ?', array('beep'),
$execute=false); ?
/pre
outputs:
---
string(31) SELECT * FROM foo WHERE bar = ?
NULL
bool(false)
bool(true)
bool(true)
bool(false)
int(0)
---
string(31) SELECT * FROM foo WHERE bar = ?
array(1) { [0]= string(4) beep }
bool(true)
bool(true)
bool(true)
bool(false)
int(0)
---
string(31) SELECT * FROM foo WHERE bar = ?
array(1) { [0]= string(4) beep }
bool(false)
bool(true)
bool(true) -- I would have expected this one to be bool(false)
bool(false)
int(0)
The above function call doesn't error out on me, it just seems it
doesn't do anything either :-\
So it seems I have to do this verboseness (AND know what the default
values are to begin with too):
SQL_QUERY('SELECT * FROM foo WHERE bar = ?', array('beep'), false, true,
false, false);
Just to change one default parameter?!? :-(
You could probably create a class and break up the functionality of that
function, for somebody reading your code would be hard understanding all
that parameters, maybe even for you after a while.

What you are wanting to do is not possible.
Back in the day, I worked on a project that used our own variation of this type
of functionality.
We had this function that helped a little
function alternate($a, $b) {
return $a = ( $a ? $a : $b );
}
function query($sql, $params=array()) {
alternate($params, array());
extract($params);
alternate($parameters, null);
alternate($showSQL, false);
alternate($showErrors, true);
alternate($execute, true);
alternate($noHTML, false);
alternate($profile, 0);
# Do your thing...
}
This allowed for us to include/exclude whatever we wanted from the
it is a little long winded to get to what you are looking for ( I think )
But it worked for us.

It's all in how it's used. Ironically, I don't remember saying
that you couldn't make a wrapper function without it, or that it was
required to make a wrapper. Thanks for clarifying that for everyone
just in case. ;-P
How would u (php) know which parameter u mean in a particular case?
You don't have to. You can send NULL or empty strings for that
matter, and use the parameter position in func_get_args() that way.
Or using hierarchy and preference:
?php
if(func_num_args() == '2') {
$first_param = func_get_args(1);
$second_param = 'default_value';
$third_param = func_get_args(2);
$fourth_param = 'another default here';
}
?
Though inelegant, it works.
What would probably be better, though, would be to write the
wrapper as I mentioned, but have it accept a single parameter as an
array, like so:
?php
function wrapper_func($arr) {
// Define variable defaults
$param_one = null;
$param_two = 'apple';
$param_three = 'foo';
$param_four = 123.45;
// Redefine variables with values passed to __FUNCTION__
foreach($arr as $k = $v) {
$$k = $v;
}
// Call original function with these values and pass through the results.
return orig_func($param_one,$param_two,$param_three,$param_four);
}
// Then use it like so:
$params = array(
'param_two' = 'Orange',
'param_four' = 543.21,
);
?
If all orig_func() did was a simple foreach()/echo routine, it
wrapper_func() would print:
[NULL]
Orange
foo
543.21
I think it would just be useful to have an IDE that can write out the
default parameters on a keyboard shortcut or mouse click and then u can
change them afterwards.
It would be nice if every programmer touching the code had the
same IDE. Unfortunately, it's just not practical.

Otherwise, what's the point of being able to set a property/variable both ways? One gives no benefit over the other and as illustrated decreases flexibility. It appears it will work if I change my property to public, but I don't want them exposed like that. *sigh* Bottom line is there should be a create_property($name, $value = null, $type = 'protected') function/method that I can call to do what I'm trying to do. I assume unset($this-foo); works. So therefore, I can check for existence of a property, and consequently remove a property, but I cannot create a property. In PHP class properties must be defined before being used. The __set and __get magic methods allow you to arbitrarily create properties, and IMHO is the most flexible way to do it. If it just worked as you want it to you would not be able to create rules around what properties can be created or what values they can hold. I use those magic methods to implement validation in my model classes. If $this-x simply created x I would have to implement it using accessor functions which IMHO is much less intuitive. When deciding whether to call __set or __get PHP looks at whether you can access the property in the current context, so if you declare a private or protected property you should be able to set its value from within the class without involving the magic methods. Hope that makes things a bit clearer. -Stuart -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hey,
well, $this-$pkey is wrong syntax. Try $this-pkey = $value
there is nothing wrong with $this-$pkey.
the question is what is __set() doing, if it's throwing an exception
for undefined properties then obviously it with 'blow up'.
I would suggest looking into using an array inside the object to
store all user data, you can still use some setter methods for user fields
that are known at compile time and for the rest you just stuff the extra/unknown
fields into the array, something like:
class Test {
private $data = array();
function loadUserData($data) {
foreach ($data as $key = $val) {
if (method_exists($this, 'set_'.$key)
$this-{'set_'.$key}($val);
else
$this-data[ $key ] = $val;
}
}
}

else
{
$class_variable = 'set_'.$pkey;
$this-$class_variable($value);
unset($user_data[$key]);
}
}
//catch (Exception $e)
{
//echo $e-getMessage().\n;
}
}
//should new fields be returned in the $user_data that are
not
accounted for above...
if ($_SESSION['DEVELOPMENT'] count($user_data))

echo !-- Unaccounted for user_data hashes. Please
add these into

PHP.

As I loop over the hash, i am TRYING to create a new class property of
the key and assigning it the value.
$pkey is basically the hash's $key in mixed case, forced to lowercase.
You can do this for variables and for functions/methods too. This is a
'factory'. I've used it for example for parsing an XML file and
operating on the data within various 'blocks' by reading the block
name=foo value=bar and then executing $$name($value).
Thanks for trying though. ;-)

If you have a previous bounce message then something like Mail Redirect https://addons.mozilla.org/en-US/thunderbird/addon/550 extension in thunderbird might work. You simply bounce the email to yourself, or from one account to another. I've used it quite often to test procmail rules, and the like. Although, as I use gmail for my email I don't have to worry about my inbox being full. Also, if you can give us more details about the actual email server then maybe there could be a way to induce the required bounce messages, somewhat like the eicar http://www.eicar.org/anti_virus_test_file.htm file is a semi-standardised anti-virus test. Then again, I run exim4, and haven't bothered looking at trying to force certain bounce messages without reconfiguring the server.

Re: [PHP] how can I make an email bounce
I guess you'd need to make the delivery fail. The easiest way to do this is probably fill up the email box. If you have control over the mail server, you could set the quota for that email box to zero. Most other failures are going to be the result of problems that may or may not be easy to replicate even if you control the server. Someone more intimately familiar with email servers might be able to give you some ideas, though. I admit ignorance on most of that. -TG - Original Message - From: Richard Kurth [EMAIL PROTECTED] To: PHP General List php-general@lists.php.net Date: Sun, 23 Nov 2008 16:01:24 -0800 Subject: [PHP] how can I make an email bounce I need to make a bunch of emails bounce in different ways so I can check to see if my script to read a mail box full of bounced emails will work properly.

Mathijs:
For MySQL failures I use:
$result = mysql_query($query) or die(report($query,__LINE__ ,__FILE__));
function report($query, $line, $file)
{
echo($query . 'br' .$line . 'br/' . $file . 'br/' .
mysql_error());
}
Perhaps you can modify that for your use.

I register an error handler a shutdown function on new features so
that I can get error reports via email. I hate trying to sift thru
logs and junk so I really need it in my face. Of course this is a
performance hit as it actually has to send emails and parse errors,
but after I haven't got any mails in a while I turn it off.
I don't really know how others debug, I work alone. But, I do all my
stuff online and use the following function:
function report($query, $line, $file)
{
echo($query . 'br' .$line . 'br/' . $file . 'br/' .
mysql_error());
}
That gives me immediate notice of where the error occurred and what
the error was. When I take my code to production, I simply comment
out the echo().
I used to use a global to do that (show/not show errors), but
consider all my error stuff in is one file, it's easy enough to
comment out what I don't want to show.

tedd

You posted a singleton pattern. That means that from the moment you call

IIUC the yet to be released garbage collection improvements will potentially find/destroy unused zvals sooner (as well as being better in sorting out defunct circular references etc) but that the garbage collection itself uses a certain ammount of cpu cycles and in short running scripts (e.g. most of what we write for the web) it's likely to be better to let php just destroy memory at the end of the request. that said your more cautious approach cannot hurt :-) PS - my apologies if the memory related terminology I've used is somewhat bogus - please put it down to my lack of proper understanding :-/ -Stut -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

not exactly - 'new' asks php to initialize an object of the given class,
the 'binding' to a variable occurs because of the assignment operator. the
__construct()
method is called automatically by php after the object structure has been
initialized, so primarily
nothing is returned because the call to __construct() doesn't happen directly
in userland code.
at least that's how I understand it.
So, constructors return nothing.

well you are still creating an instance of the object. the only difference

you are forcing it the ref count to 0 by assigning the instance to a local
local variable.

both your and my code use static methods. it sounds to me like you are

From your previous email
?php
class Test {
public static function doSomething() {
$o = new Test();
The above line IS creating a instance of the class Test
Now with proper garbage collection, it should be wiped out when you are done
using the static doSomething() method.
$o-_doSomething();
You could always include this to remove the instance of class Test
unset($o);
}
protected function _doSomething() {
// I'm assuming this method is fairly complex, and involves

Ok, I'm going to have to assume you really are as stupid as you seem. If
I need to provide an example to demonstrate what I meant I will, but I
feel I made it quite clear that my comment regarding what *I* would do
did not in any way relate to the code example I had provided above. The
example I provided was fulfilling the OP's requirements.
This is what *I* would do...

}

Look ma, no instance.
FYI I'm not at all new to OOP, in general or in PHP, so I am well aware
that the example I originally posted created an instance of the class.

Now this is clear.
But to point out in the code I quoted, you said that you were going to only use
the static method, but you were calling the static method that created an
instance of the Test class and then calling the non-static method from the
instance of the Test class.
Your previous example was not showing us what you were saying. To me it looked
like you were confused about how you were calling/creating things.

clearly not.

I was never confused! ;)
