You will need to use AJAX/COMET requests. Regular XMLHttpRequest AJAX
requests will not do because when you send the AJAX response your script
exits.
With AJAX/COMET requests you can send several responses to the same
request without exiting the script, so you can show progress report.
Take a look at these articles:
http://www.phpclasses.org/blog/post/58-Responsive-AJAX-applications-with-COMET.html
http://www.phpclasses.org/blog/post/51-PHPClasses-20-Beta-AJAX-XMLHttpRequest-x-IFrame.html
This forms class comes with an AJAX/COMET plug-in that allows you to
show progress of a task running on the server without page reloading in
a single request.
http://www.phpclasses.org/formsgeneration
Here is is a live example script that show progress of a task running on
the server after the form is submitted.

I can confirm this. you definitely need to open a connection for each child
process.
if you require a db connection in the parent process, you should close
it before forking (and then reopen it afterwards if you still need it).
at least that's what I found I had to do when I ran into this.
incidently my forking loop looks like this, very interested to know if

$childProcs = array();
do {
if (count($childProcs) <= $maxChildProcs) {
$site = array_shift($sites);
$pid = pcntl_fork();
} else {
// stay as parent, no fork, try to reduce number of child processes
$site = null;
$pid = null;
}
switch (true) {
case ($pid === -1):
cronLog("error: (in {$thisScript}), cannot initialize worker
process in order to run {$script} for {$site['name']}");

// we are child
$exit = 0;
$output = array();
// do we want to exec? or maybe include?

exec($script.' '.$site['id'], $output, $exit);
} else {
$output = inc($script);
$output = explode("\n", $output);
}
if ($exit != 0)

I can't quite follow your code after the pcntl_wait where you've got a
pcntl_kill(), but it looks like an insurance policy? "just in case" ?

correct, from my reading the pcntl_kill() with a signal argument of zero should
return true if it is *able* to send the signal (but it doesn't actually send
anything),
given that it's only checking it's own children the parent process must able to
send them signals assuming they're not somehow dead ... so yeah, insurance
policy :-)

I thought that too, but this code seems to work, which seems to imply that
the child doesn't kill the existing db connection.
$conn = mysql_connect($sharedAppsDbHost, $sharedAppsDbUser,
$sharedAppsDbPass, true);
foreach ($things as $thing) {
temp($thing);
}
function temp($thing) {
global $conn;
extract(getInfo($thing)); // this function call uses a shared db
connection
mysqlSelectDb($dbName, $conn); // dbName is a variable gotten from the
above call
$result = mysql_query("SELECT COUNT(*) FROM Users",
$conn);
$row = mysql_fetch_array($result, MYSQL_BOTH);
echo "$row[0]\n";
$pid = pcntl_fork();
if ($pid == -1) {
die("could not fork");
} else if ($pid) {
// parent, return the child pid
echo "child pid $pid waiting\n";
pcntl_waitpid($pid, $status, WNOHANG);
if (pcntl_wifexited($status)) {
echo "finished [$status] waiting\n";
return;
}
} else {
echo "child sleeping\n";
sleep(3);
echo "child done\n";
exit;
}
}
==============
My main problem here is that I have a set of helper functions (getInfo is
one of them) that uses a global db connection that exists in that helper
script. Otherwise, I have to rewrite the function to create a new
connection every time, which I'd like not to.

Whoops, I spoke too soon, I think the sleep(3) causes the child not to exit
before the parent. If instead I don't pass WNOHANG to the waitpid command,
it does error out. So it looks like your theory is correct, and I still
have that problem. I guess the only solution is to rewrite the functions to
use a new db connection every time? Or maybe I should just sleep the child
thread for long periods of time and hope the parent thread finishes in time
(which admittedly seems really hacky)?

Each child should open its own database connection (if it needs one),
and the parent should not keep the connection open at time of fork().

I suspect that may happen with nervous users that double click form
submit buttons.
Usually I use this forms class that has a built-in feature to show a
form resubmit confirmation message when the use uses the submit function
more than once:
http://www.phpclasses.org/formsgeneration
That feature can be seen in this page:

Yes possible. But you wrote the query in a bit confused way.

you want a form which will let user choose a working form to be placed

I have been tearing out my hair to figure out a way to place array
values into $variables with not much luck. I can echo the array to the
screen but I can not manipulate the results.
I have searched wide and far all day on the web and I find nothing that
points the way how to extract values from an associative array and
assign them to a variable.
I expected to find some elegant way to do it. Here's the code that
outputs the values:
if ( isset( $book_categories[$bookID] ) ) {
foreach ( $book_categories[$bookID] AS $categoryID ) {
if ( isset( $category[$categoryID] ) ) {
echo($category[$categoryID]['category']);
}
}
}
this will echo something like "CivilizationGods And GoddessesHistorical
PeriodsSociology & Anthropology" (I have not added breaks beween the
categories as there is more manipulation needed on them)
This works for as many categories as needed. Manipulating each value
should not be a problem once it is in a string variable using switch and
preg_replace() as each category needs to be stripped of spaces, commas
and &s.

Same as other variable assignment.
if ( isset( $category[$categoryID] ) ) {
$myvar = $category[$categoryID];
}
echo $myvar . "<br/>";
Doing it with a multi-dimensional array is no different to a result set
from a database or any other scenario.

I probably did not express myself clearly; I thought I did:
"place array * *values ** into * *$variables **"
the output of $myvar above is Array. That, I knew. And that does not
extract. I can see what is in the array in several ways; the problem is
to get the output into $var1, $var2, $var3 ... etc. How do I convert:
$category[$categoryID]['category'] into up to 4 different variables that I can
manipulate?
My code above outputs text like this: "CivilizationGods And GoddessesHistorical
PeriodsSociology & Anthropology"

Thanks for the suggestion. I've seen that example and have tried it as
well as about a dozen others.
The problem is that the $array returns another array (multidimensional
and associative ?? )
print_r($myarray) returns for example:
Array ( [id] => 5 [category] => Some category)
Array ( [id] => 33 [category] => Another category)
So, you see, I can't do anything with that. I had hoped to be able to
use something like count() or $row() or foreach or while but no go.
foreach may have a possibility but it it rather convoluted and I'm
trying to avoid it; hoping for something simpler, more logical and more
"elegant".

Try this
$my_categories = array();
foreach (......) {
if (isset($category[$categoryID])) {
$my_categories[] = $category[$categoryID]['category'];
}
}
At the end, you can either:
foreach ($my_categories as $category_name) {
.. do something
}
or
$category_list = implode(',', $my_categories);
echo "The categories are ${category_list}\n";

1. What is the overhead on preg_replace?
2. Is there a better way to strip spaces and non alpha numerical
characters from text strings? I suspect not... maybe the Shadow does ???

1. What is the overhead on preg_replace?
Compared to what? If you write a 3 line regex, it's going to take some
processing.
2. Is there a better way to strip spaces and non alpha numerical
characters from text strings? I suspect not... maybe the Shadow does ???
For this, preg_replace is probably the right option.

I just answered a question similar to this. You might check the
archives. In this case, you'll need to use the getdate() function (see
php.net/manual/en/ for details) to get the array of values for today
(like the day of the month, month number, year, etc.). The getdate()
function returns an array, one of whose members is 'wday', which is the
day of the week, starting with 0 for Sunday. Use that number to
determine how many days to go back from today. Then use mktime() to get
the timestamps for each day in turn. You feed mktime() values from the
getdate() call. Then you can use strftime() or something else to print
out the dates in whatever format, given the timestamps you got.
Be careful in feeding values to mktime(). If your week spans a
month or year boundary, you'll need to compensate for it when giving
mktime() month numbers, day numbers and year numbers.

A sprinkle of math + a sprinkle of time + a sprinkle of PHP:
<?php
$dates = array();
$offset = (int)date( 'w' ) - 6;
for( $i = 0; $i < 7; $i++ )
{
$dates[] = date( 'l F j, Y', strtotime( '+'.($offset + $i).'
days' ) );
}
print_r( $dates );
?>
Cheers,
Rob.

Hi ash,
Thanks for your feedback first.
Actually registration helps admin to track an user . Additionally if
you are registered you can see your previous results for different
Quizzes. That's what I thought It is good to have registration
restriction. I think its a small cost to pay for an User if all the
Quizzes are being provided Free.
If majority will say to remove the registration process I can do so.

Thanks and Regards.
