The problem is that the php installation on this server is not 
configured correctly.  It still holds the default session location 
(/tmp) which doesn't exist on Windows PCs.

You need to ask the server administrator to verify the PHP installation 
and point the session location directory to a valid location on the server.

Thanks for your reply. I can understand the reasoning for that. However,
what the request was about was _optional_ explicit typing; the standard
library didn't have to use it at all, but it would be available to users.
Many places in a web application pass values between functions, where the
type is well-known (i.e. not directly from a browser).

Nevertheless, I assume the official answer is the same, and I understand it,
if this is not a reasonably commonly requested feature.

Terje

Yes, I think so, too, and I thought of that, as well. I think it does
something similar. I checked now: yep, it does the same there.

I realise that it may seem counter-intuitive or strange, but in this case it
actually makes sense: To take a practical example: A stopwatch FSM (example
from boost::fsm
(http://cvs.sourceforge.net/viewcvs.py/*checkout*/boost-sandbox/boost-sandbo
x/libs/fsm/doc/index.html?content-type=text%2Fplain&rev=1.31)). Here's a
complete, working example (except for the fsm class):

--- Start code ---

include_once("fsm.php");

// States (nested classes are not supported, so these must be at global
scope)

class active {}
class running extends active {}
class stopped extends active {}

class stopwatch_fsm extends fsm
{
  public function stopwatch_fsm()
  {
$this->fsm("stopped"); // Initial state
$this->add_transitions($this->transitions);
  }

  protected function start($from_state,$to_state)
  {
echo "Start stopwatch";
  }

  protected function stop($from_state,$to_state)
  {
echo "Stop stopwatch";
  }

  protected function reset($from_state,$to_state)
  {
echo "Reset stopwatch";
  }

  private $transitions=array(
//, , , 
array("Start/stop button", "stopped", "running","start"),
array("Start/stop button", "running", "stopped","stop"),
array("Reset button", "active", "stopped","reset"));
}

--- End code ---

To explain the above:  The FSM stopwatch_fsm contains a state "active", with
two nested states "running" and "stopped". These are modelled as classes.
The transitions between the states are defined in the above array, each line
gives a signal/initial state/final state/action for a transition. For
example, if it's in the "stopped" state, and receives a "Start/stop button"
signal, it transitions to the "running" state, and calls the start() member
function. Same for the other two defined transitions.

Test program:

include_once("stopwatch_fsm.php");

$test=new stopwatch_fsm();

$test->process("Start/stop button");
$test->process("Start/stop button");
$test->process("Start/stop button");
$test->process("Reset button");

This will print:

Start stopwatch
Stop stopwatch
Start stopwatch
Reset stopwatch

The idea is that fsm will, upon doing state transitions, call the
appropriate action functions, as member functions (here, start/stop/reset),
so these have to be defined in the derived class. Interestingly, this
actually works even if start/stop/reset are _not_ defined in the base class,
fsm (!)

I seem to have talked myself into a corner. :) As these functions are not
defined in the base class, they are _not_ overridden in the derived class;
they are merely defined there. The example I had in the original posting was
a member function that _was_ defined in the base class, and overridden in
the derived class ("null_action"). This is the member function that gets
called, if no specific action function is provided in the transition table.

In _that_ example, the derived class would need to be able to override it,
but need not be able to call it (as it's called by the base class).

I hope this makes some kind of sense... :)

(By the way, besides pear::fsm, this is also inspired by the mentioned
boost::fsm, which also uses classes to model states)

Is it possible to track this as a statistical graph that gives us average

Hm, good point. However, this essentially means you have to do "manually"
what the compiler could have done. For example:

function f($a,$b,$c)
{
  assert("is_int(\$a)");
  assert("is_string(\$b)");
  assert("is_array(\$c)");

  // Actual function content here
}

At one time, I actually started to do this, but in the end, I found it
cluttered more than it helped; all those extra lines for each parameter:
clearly, the language worked against me on this. On the other hand, had I
been able to do this:

function f(int $a,string $b,array $c)
{
  // Actual function content here
}

then it would have been just fine. It also works as documentation,
specifying what the function expects (and might also specify what it
returns).

Yes, and I'm not against the dynamic/loose typing of PHP. However, as
mentioned in the other reply to Rasmus Lerdorf, there may be areas in your
application where the types are well-defined (not from GET/POST), and where
this might help. Even with GET/POST requests, it's often recommended to
"sanitize"/check these before using the values, and in this process, you
might fix the types (you can't very well check a a value you don't know the
expected type for).

Indeed, and it means all the selection have to be done in _one_ function.
Sure, varargs can give you some kind of overloading, but as with using
assert and is_* above, to check for incoming types, you essentially have to
"manually" provide the overloading (by checking argument number and types,
and dispatching appropriately), and then the alternative of using
differently named functions really look more appealing...

Besides, this makes the "switch function" a dependency hog: Every
"overloaded" function you add means you have to change it. If it's in a
third-party library, this may not be useful option.

its alternatively call 'php internals', I have read a lot of your

returned. I ran the snippet above and the only msg I can get is 'Can't
Select Database'. However when I drop the $db line, I get no msg at all. Any
Ideas would be appreciated with a caveat.

I am building a commercial site for myself. The concept documents can be
found at POTBOWLING.COM. I cannot pay anyone for assisting me unless we have
a prior arrangement and until this thing gets off the ground bringing in
real income. Please do not send any response with the intent of making
claims against the project later unless we have an understanding.

I have already run this thing back in the '80's on a DOS based BATCH process
system, and after three failed attempts and all my money to get others to
write the code in the Web World, I am going to do it my self. At least the
proof of concept which will prove the functionality, without the bells and
whistles, that this can work, at which point I hope to acquire funding to
build the security and beef up the code, look and feel of the website. I do
have interested parties waiting to see what I can develop who are willing to
move this along.

So, with that in mind and an understanding that if you can help now, and
this thing goes, I will need a solid staff to help develop and then maintain
this project. Once this one is up and running I have also done another DOS
based project in the Golfing world.  I welcome your assistance. Please reply

[PHP] array search

[Malcolm]

Hello All,
  I've been trying for days now to make this work.
I'm trying to search my array for a value and return the key.
I get the visitor's IP and try this  -- this is the latest,
I've tried a few functions to echo the name associated with the viz_ip.
$viz_ip= $_SERVER['REMOTE_ADDR'];
$byte_ip= array(
"204.126.202.56"=>"Mark",
"63.230.76.166"=>"Bob",
"63.220.76.165"=>"John",
);
function _array_search ($viz_ip, $byte_ip) {
   foreach($byte_ip as $key => $val) {
   if ($viz_ip === $key) {
   return($val);
   }
   }
   return(False);
   }
I'm no wiz but this shouldn't be this hard, maybe I'm thinking wrong.
I've read the examples at php.net but I just can't get it. Some help
or even a hint ?
best regards,
malcolm

This worked for me (with my IP address for 'John'):

"Mark",

"63.230.76.166"=>"Bob",

"84.196.101.86"=>"John",
);

function _array_search ($viz_ip, $byte_ip) {

foreach($byte_ip as $key => $val) {

Thank you Sirs,
  I was echoing the viz-ip so I know it was getting set but
I couldn't get it.
  both work  ..  I got the clue from John, the last echo line did the  
trick.

I might be the only one to notice here, but you don't want to find the 
KEY, you want to find the VALUE. Otherwise, you'll need to assemble your 
array differently.

$viz_ip= $_SERVER['REMOTE_ADDR'];
$byte_ip= array(
   "204.126.202.56"=>"Mark",
   "63.230.76.166"=>"Bob",
   "63.220.76.165"=>"John"
);
That means:
$byte_ip[$viz_ip] = some_name;
That's because you have ips set as your *keys*, and not your values. To 
do what you wanted, simply either:
a) reverse the array, making keys values and values keys:
$byte_ip= array(
   "Mark"=>"204.126.202.56",
   "Bob"=>"63.230.76.166",
   "John"=>"63.220.76.165"
);

or:
b) change the function to match on key (for which you don't *need* a 
function).

[PHP] php-db@lists.php.net

[Ralph Frost]

I had a php routine on a shared server running as a CGI script that 
encrypted and sent email text.

It was running fine under PHP version 4.3.6. Then the ISP upgraded to 
4.3.10  on December 16, 2004 and several of the features in the gpg 
encryption script running in cgi-bin stopped working.

phpinfo()  in a script run from cgi-bin reports  Server 
API  =  Apache.Isn't it supposed to be CGI??

Initially, fopen(),  mail(), and the passthru( ) of the gpg command  would 
not work.

The ISP did something, and  got it back so fopen() and mail() works, but 
files are still being created as "nobody nobody".  The gpg command that 
works from the shell, returns result=2  when run through the script.

I've tried shell_exec() also.
Isn't running the script in cgi-bin  SUPPOSED TO run as myusername rather 
than as nobody?

What mistakes m I making?  Is this a php upgrade/configuration problem that 
the ISP needs to look at,  or it is a general security issue which used to 
work but  now is not going to be allowed... and the ISP doesn't want to 
tell me?

Any thoughts or suggestions, inside or outside the box on how I can get 
back to the same functionality as I had before December 16, 2004?

Thank you in advance for any help you can offer.
Best regards,
Ralph Frost

[PHP] Attempting to use 'passthru' or 'exec' function

[Andre Dubuc]

Hi, 

I'm trying to output a text file from a pdf file using an external function, 
pdftotext, using either PHP's 'passthru' or 'exec' functions.

The following code sort of works (at least I see localhost busy doing 
something for about three seconds, but  the expected output of 'content.txt' 
is empty. I used an idea found on the mailing list: I actually got some 
activity with 'sudo desired_function arg1 arg2'.

File permissions are set wide open (apache:apache 777), safe_mode=off.

What am I doing wrong? (Btw, the pdftotext function works fine on 
commandline).

$Pdf";

passthru("sudo pdftotext /var/www/html/2005-o1-v2.pdf.txt 
/var/www/html/current.txt");
*/

$current = "current.txt";

print "Current Text: $current";
$string_text = file_get_contents("current.txt");
$new_text = nl2br("$string_text");

?>

Any help, pointers, admonitions gratefully accepted,
Tia,
Andre

That may well be. :) As mentioned, I've worked with PHP a couple of years,
but have been doing C++/Java much longer (and C before that). I have started
to adjust to the dynamic nature of PHP, and as mentioned in another post,
about variable variable functions and variables, there are some useful
things that this enables, as well.

Nonetheless, the discussion of explicit/implicit typing is a valid one, and
my posts were not at least meant to see what other people think, and if
there are other approaches that kind of compensate for the risk of bugs with
implicit/dynamic typing. Guido van Rossum (Python's creator) and some others
have argued that unit tests may make up for it. Well, unit tests are nice,
but with type checking by the compiler/runtime, you may concentrate on the
non-trivial tests instead, rather than testing something the
compiler/runtime is perfectly able to do by itself.

Well, but this is great news. :) I.e. then I have a place to look. As I said
at the start, I hadn't found discussion about this, but then, I haven't
really known which archive(s) to search, either.

Of course, people won't have to go into a discussion that has happened
before; just point to a previous one, as you did. :)

Aren't they everywhere. ;)

Thanks. :) I haven't received any flames, yet, at least. :) I didn't really
know how they would be received, given that I don't know the community.
(I've usually been hanging around the ACCU lists, as well as Boost, and
comp.lang.c++.moderated, comp.std.c++, so I mostly know the C++ community.)

The problem is that the php installation on this server is not 
configured correctly.  It still holds the default session location 
(/tmp) which doesn't exist on Windows PCs.

You need to ask the server administrator to verify the PHP installation 
and point the session location directory to a valid location on the server.
You also have the option of creating your own session location directory 
by inserting the following at the beginning of each script.

session_save_path('...public/tmp');
I happen to do this because my hosting company uses load balancing which 
means I can never know what server is processing my PHP script. I place 
my session location in a tmp folder in my public directory. Otherwise I 
would lose my session variables periodically.

[PHP] PHP Application server

[Devraj Mukherjee]

We are evaulating the idea of writing a PHP application server. Its aimed
to be a stateful environment for writing PHP applications and we believe
it will be quite advantegous to the entire community.

Any ideas if there are a similar solutions that already exists out there,
and what is the general feel of a solution like this.

Thanks for your time and feedback.

Devraj

1) What does your php error log say?
2) Is there any reason you're using sudo? Do you know how it works and have 
you configured sudo correctly?
3) Commands like passthru() and exec() allow you to check the return value of 
the system command being executed -- use it.

Change the above line to the following for a more useful error message from 
mysql:
$db = mysql_select_db("wwpbt", "$conn") or die ("Can't Select Database". 
mysql_error());

which wont help much - assuming what you say is true
(why wont it work? have you tried it).
sort method from the class:
function sort()

   if(count($this->sortKeys)) {
   usort($this->dataArray, array($this,"_sortcmp"));

}

Thanks jochem, I had a second look at it and I figured it out. I had 
problem implementing it with a class but now I have figured how to use it.

cheers,

[PHP] Zend Performance Suite 3.6 and PHP5

[Lars B. Jensen]

I've taken over the system administration of our servers, and have been 
migrating from PHP4 on Redhat, to PHP5 on a FreeBSD system setup.

Few questions,
Is this version of the ZPS compatible with PHP5, I mean, the software was 
bought back in dec. 2003 and never updated since. (the new Zend Platform is 
outrageously priced, and I'll never get that through on the IT budget here)

Does anybody know where to download the source for this, the old (and 
ofcourse not working here anymore) admin didnt keep the source, so all I got 
is the name and serial. (and Zend supporters seem to be "on vacation")

With the "Zend Platform" out of the way, should I look more toward eg. the 
APC ?

My statement was, 

if ($i = $n_elts -1)

{
echo "On last element";
break;
}

i.e.

- assign ($i = $n_elts -1) and check the return value of the
  assignment. 

- If the assignment succeeds (which should, unless you are running
  short of free memory) THEN

- echo 
- BREAK out of loop 

Since this conditions are met the first time the loop runs, the loop
will run only once. I know I am correct, since I ran the code this
time :P
