Sorry, I don't understand the problem. The average user will obviously
have a suitable keyboard, such as this for instance:

/Per Jessen, Zürich
I hope you're right.
However, it's one thing to have a keyboard
designed for a specific language and another to
be able to enter code-points that aren't
associated with any specific language (i.e.,
Dingbats and Math Symbols).
For example, note that Rx,com is not associated
with any language, which is the same as many of
my other domains, as you can see some here:
http://symboldomains.com/symbol-domains-for-sale.html
I bought most of these eight years ago hoping
that someone would see things the way I do. But
despite all my time, effort, and cost -- the only
thing I have received is being called a goofy
nitwit -- which I probably am -- but I would like
to think of myself as an entertaining nitwit. :-)
I have grandiose plans, but unfortunately I'm the only one who see's them.

tedd

yes I have one, so? did he build your website per chance? :-P
btw:
I have two handcoded cmses that I use to build sites with,
a bunch of code 'snippets' used to handcode very small odd-ball sites
with and I sometimes use an out of the box CMS if it suits me
(but not Joomla) ... and I always end up having to hack some
customization into them.
as a developer it's not just about getting a quick result but
aquiring a level of expertise that allows one to understand and create
things at a professional level, things like CMSes (somebody actually
writes them!) using validating, tableless xHTML layouts, valid CSS,
secure server-side code, unobtrusive (and sometimes even gracefully
degrading) javascript, etc, etc.
the pond is getting smaller and smaller, eventually there won't be
any room for people who can just about run the installer script of
CMS X[tm] and barely hack out HTML. I plan to be getting paid still
when that happens ... rewriting the installer script of CMS X[tm] perhaps.

anyone know if it's possible to grab the entire commandline
that was used to start up a php script on the CLI, an example
of what I'm looking to grab from within the script (test.php in
this example):
"php -qC -ddisplay_errors=1 ./test.php -o -d -e [EMAIL PROTECTED] -f
./last.log | grep Exception"
of course I know what the script name and arguments are but I'd rather like
the
whole enchilada (php binary and it's args + the pipe to grep).
possible? bad idea? down boy?
Not possible, I'm afraid. Certainly not portably. The command line is
manipulated quite heavily before your script gets run. (eg shell
wildcard expansions).
I have a feeling I'm out of luck - probably security issues that keep
you from doing such a thing as well.
I did have the idea of grabbing the PID and then grepping the output of
ps via exec() ... that would do it, but I reckon it smells. :-)
A quick Google suggests that it is possible under VMS, but I doubt
that's much use to you.
STW wasn't giving me any joy either, it's for linux only (although it
would be nice if it worked on my Mac)

I suggest creating a shell wrapper for PHP that will write the command
to a file for you and then call PHP with the appropriate arguments. PHP
won't even see most of the command that you originally posted.

I doubt it. The ps command sees what the script sees. If I do mplayer
*.avi, ps shows me the expanded file list that was given to mplayer.
Remember, shell gets first dibs before anything happens. BTW your
subject line does not imply that you wanted the EXACT command line
used :)

Application and Templating Framework for PHP
--- End Message ---
--- Begin Message ---
Hej everybody,
I built something I'd like to have feedback on. Looking at all the
template engines out there made me think.
I have two main requirements:
- use PHP as the template language
- effective XSS prevention without betting on discipline
Plain PHP only satisfies the first. I also couldn't find a PHP template
engine that satisfies both. (Savant doesn't.)
So here is my own minimal solution and I would like to know your
opinion. Also, if anybody has seen something like it out there, please
point me to it.
The Idea:
Automatically wrap every output string into a Decorator object, which
offers filtering methods like htmlentities. This also means intercepting
access to strings contained in Arrays and Objects in order to decorate them.
The code:
http://code.google.com/p/cvphplib/source/browse/trunk/cvphplib/
svn checkout http://cvphplib.googlecode.com/svn/trunk/cvphplib/
Example usage:
// first a simple string
<? $string = CV_OutputFilter::filter( '<marquee>evil</marquee>' ); ?>
<?=$string?> triggers an error
<?=$string->htmlentities()?> works fine
<?=$string->urlencode()?> works fine
<?=$string->raw()?> outputs the unfiltered value
// extracting a bunch of filtered variables into the local scope
<?php
$vars = array( 'x'=>5, 'o'=>new O(), 'array' => array('<i>'=>'<b>') );
extract( CV_OutputFilter::filter($vars)->toArray() );
?>
// access to object members
<?=$o->var?> triggers an error
<?=$o->method()?> triggers an error
<?=$o->var->htmlentities()?> works fine
<?=$o->method()->htmlentities()?> works fine
// access to array elements
<?=$array['<i>']?> triggers an error
<?=$array['<i>']->htmlentities()?> works fine
// Iterating over an array
<? foreach( $array as $value ){} ?> works fine
<? foreach( $array as $key => $value ){} ?> throws an exception, because
$key would not be filtered in this case
// decorating array keys requires some iterator magic
<? foreach( $array->key_as($key) as $value ): ?>
<?=$key->htmlentities()?>: <?=$value->htmlentities()?> <br/>
<? endforeach; ?>
Problems:
- potentially slow (due to many object instantiations and reflection)
Benefits:
- effective XSS prevention without betting on discipline
- template-engine-like variable extraction into local scope
- clean and short syntax
- very little to learn
Functionality already implemented, but not shown in the example:
- register custom filter methods
- enable __toString() with custom default filter
- use tuple array(key,value) for $value instead of 'key_as'-magic
- register custom filter applied on keys in ->toArray()
- decoration of multidimensional arrays and webs of object references
More example code:
http://code.google.com/p/cvphplib/source/browse/trunk/cvphplib/examples/exampleOutputFilter.php
http://code.google.com/p/cvphplib/source/browse/trunk/cvphplib/tests/CV/Test_OutputFilter.php
So what do you think?
Best regards

Hi guys,
I need to send post variables to an ASP page. I have the following code which
isn't producing any errors but isn't working either:
foreach($_POST['newsletter-group'] as $key => $value){ $_POST['addressbookid']
= $value; $out = "POST /signup.ashx"; $fp = fsockopen("dmtrk.net", 80, $errno,
$errstr, 30); if (!$fp) { echo "$errstr ($errno)<br />\n"; } else {
fputs($fp, $out . "\r\n"); } fclose($fp); }
Can anyone tell me what I am doing wrong please?

IIRC ASP cant recive PHP $_POST variables but it can recive HTML post
from forms.
If you want to send variables to another language. You can try via a
get variable. Dont know if the items you want to send are safe to send
over though.

If they only want a simple set of pages, then it's probably not worth the
hassle of configuring a CMS framework. The second you want to add 'customer
login' so that their clients can view private things like their log book or
next flight booking then you need a CMS with a good user management and
security system. Event diary and other automated functions then come free with
any decent framework.
With bitweaver I can add my own special functions while still retaining all of
the core functions of styling, themes, user management and security.

You're not really a PHP developer until you've written your own CMS from
scratch. It's a right of passage to roll your own, realize what a bad idea
it is, and move on to using a full on general CMS that will do 10x what you
can do on you own in 1/10 the effort on your parts.
My own bias is for Drupal, since that's the system I work on, but most will
work well enough depending on your needs. (Drupal will work better, though!
<g>) The bragging rights of doing it youself don't actually carry as much
weight as you'd think; the bragging rights of knowing how to leverage a
tier-one system that has major name recognition is even more valuable. The
bragging rights of being a developer on that system is even more valuable.
There's educational value to writing your own, but it will take longer and
result in fewer features than using an existing system. Most major CMSes
have tens of thousands of hours of work put into them; 60 hours won't even
get you a really good blog.

In writing the script, though, there are two points. I don't always use
checkboxes, sometimes I just want to update all the records on the
form. Eg I have a series of images and related text each with their ID
in the database table, on clicking update all the form elements get
submitted and I need to relate the relevant image, text, etc with the
table ID. So I can't rely on checkboxes which only get posted if
ticked. So again I have to iterate through all possible IDs. Which
normally can be done but it is longer, eg because the images on the page
in the first place may not be the result of a simple select query. So I
suppose the solution there is to have a hidden field with all the IDs as
a string, explode that and then iterate through that. Eg
<input type=hidden value="1_2_3" name="all_IDs">
$IDs=explode("_",$_POST['all_IDs']);
and that gives me the table IDs to do update queries on etc.

That solution would probably work just nicely.
That being said however, If you want to be sophisticated about this you
would make good use of JSON and php's corresponding functions
json_decode/encode which is common way to transport arrays as strings - and
much more.

Subject: Re: [PHP] Re: Variable name as a string
In writing the script, though, there are two points. I don't always use
checkboxes, sometimes I just want to update all the records on the
form. Eg I have a series of images and related text each with their ID
in the database table, on clicking update all the form elements get
submitted and I need to relate the relevant image, text, etc with the
table ID. So I can't rely on checkboxes which only get posted if
ticked. So again I have to iterate through all possible IDs. Which
normally can be done but it is longer, eg because the images on the page
in the first place may not be the result of a simple select query. So I
suppose the solution there is to have a hidden field with all the IDs as
a string, explode that and then iterate through that. Eg
<input type=hidden value="1_2_3" name="all_IDs">
$IDs=explode("_",$_POST['all_IDs']);
and that gives me the table IDs to do update queries on etc.

Hello guys,
I've been stalking on the list for some time. Didn't have
anything to report/talk, until now. I have a code like this, maybe you guys
can reproduce it, with output buffering started:
Echo 'something';
Echo 'another thing';
Echo 'something <br />'\;
What happens is that ANYTHING that was echo'ed until that \,
will not reach the buffer. Although, this should actually be a Parse Error,
it isn't, it just echoes what was echoed after the god damned \. It took me
two hours to find this typo in the code .
Can you guys reproduce the error? I can actually give you a
link to the server where this code runs.
