Steve,
Check out the while loop

what you need.

Your shared host may provide no access to config an MTA, but will shut
you down automatically if you send either more then 75 emails per
minute, or more than 1000 per hour.
I worked on such a setup, and crafted a PHP DB queue of emails to make
100% sure their mailing list never got their site shut down.
I am confident other examples abound.

You are right. After all that is an "MTA" too. It is an awkward solution
but tt least you will be able work around your ISP constraints.
Some time ago an user published a class that does precisely that:
http://www.phpclasses.org/newsletter
In the past, I used also an unsual solution to send newsletters to the
PHPClasses site users.
Instead of a database, I used to send e-mail messages that contained
newsletter contents and subscriber addresses.
Then I used my desktop machine to pop the messages and distribute the
newsletters. When it exceeded my ISP limits, I used servers borrowed
from kind users, until I finally used a VPS.
The distribution system via e-mail still exists and works as a charm,
although for now it is not needed to work distributedly.
In this blog post you can read all the details.

I wanted to avoid the whole concat versus multi-arg performance
thread, since it usually takes about a week before somebody posts the
definitive answer, showing the actual PHP opcodes generated...
And I don't recall the answer, and don't give a [bleep] since it's
almost never the bottleneck in an application in the first place...

Thanks for idea, Richard. But it doesn't work.
I wrote code as you said:
--------------------
$first = "/usr/local/bin/mencoder -vf scale=448:-3,expand=448:336 -sws 9 -of
lavf -ovc lavc -lavcopts
vcodec=flv:vbitrate=250:trell:v4mv:mv0:mbd=2:cbp:aic:cmp=3:subcmp=3:vpass=1
-frames 800 -ofps 24000/1001 -oac mp3lame -lameopts abr:br=64:mode=0 -channels 1
-srate 22050 -of lavf -lavfopts format=flv -o ".$outputFile."
/home/re/ff/logo7.avi ".$inputFile."\n";
$second = "/usr/local/bin/mencoder -vf scale=448:-3,expand=448:336 -sws 9 -of
lavf -ovc lavc -lavcopts
vcodec=flv:vbitrate=250:trell:v4mv:mv0:mbd=2:cbp:aic:cmp=3:subcmp=3:vpass=2
-frames 800 -ofps 24000/1001 -oac mp3lame -lameopts abr:br=64:mode=0 -channels 1
-srate 22050 -of lavf -lavfopts format=flv -o ".$outputFile."
/home/re/ff/logo7.avi ".$inputFile;
$fp = fopen("/home/re/video/enc", "w");
fwrite($fp, $first);
fwrite($fp, $second);
fclose($fp);
exec("/bin/bash /home/re/video/enc");
--------------------
I've also tried system() instead of exec(), and it displayed same output text as
I posted above.
The strangest thing is when I run this script from shell, everything works fine!
Video encodes well. But when I call that script from PHP, nothing works.
Another strange thing is I run ImageMajick with system() in a lot of scripts on
the same server and everything works fine.
What is the problem? Do you have any idea?

My reply is a bit pointless as I'd never do/rely on this. But
nonetheless it was an interesting test.
function testObj() {
$arr = array();
$arr['key1'] = array(1, 2, 3);
$arr['key3'] = array('a','b','c');
return (object)$arr;
}
echo '<pre>';
echo "Key1: \n";
print_r(testObj()->key1);
echo "Key3: \n";
print_r(testObj()->key3);
--- output ----
Key1:
Array
(
[0] => 1
[1] => 2

I am trying to get the information in name and order to update the database.
So far, I can only get one or the other. Is there a way to do this?

there are a few different issues here; first of all; are you sure
$_POST['name']
and $_POST['order'] are even arrays?

To check try this right above your saving code block:
echo '<pre>';
print_r($_POST);
After you figure out if your data is right we're going to have to talk
about input validation and sql injection.

Steve,
// Do you have several html form elements such as <input type="text"
name="name[]"> in your html?
// Mike's suggestion...
if( isset( $_POST['name'] ) && is_array( $_POST['name'] ) ) {
// you'll never get in here if you don't...
$name = $_POST['name'];
// foreach expects an array, as Nathan states. Even if $name is an
array, $t
// will hold only the last value in the array when the foreach loop
is exited
// because $t is being overwritten with each iteration.
foreach ($name as $t) {
echo "$t";
} // end foreach ($name)
$order = $_POST['order'];
if ($order) {
// see above about arrays and foreach
foreach ($order as $i) {
//Update the table in MySQL
$i = mysql_real_escape_string($i, $cnx); // One of
Eric's suggestions
$update_data = "UPDATE sections SET `order` = '$i'
WHERE name = '$t'";
$response = mysql_query( $update_data, $cnx );
if(mysql_error()) die ('database error<br>'.
mysql_error());
echo "$i";
} //end foreach ($order)
}
}
Assuming both $_POST['name'] and $_POST['order'] are arrays, the way your
code is now structured, the table `sections` will have the record(s) where
name equals the last value in the $names array updated multiple times, once
for each value in the $order array, but all you will see is that
the record(s) will have the last value in the $order array.
See if this makes any sense and then ask more questions.

I am trying to get the information in name and order to update the database.
So far, I can only get one or the other. Is there a way to do this?
Thanks for your help.

Notice the differences
Pay close attention to the form and see how I am nesting the fields in
the input name attribute.

the topic of external variables, including the ability to create arrays from
outside php,
such as in GET and POST requests can be found here:

Hi all,
Maybe this is a somehow stupid question.
I want to know how php could know whether session_start() has been called, that
is, whether session has been started.
I Googled, but got little help.
Thank you for help!
Any tip is greatly appreciated.
Regards,
Shelley

http://us3.php.net/session_id
is what you are looking for.
Look at the notes for the "Return Values" section
"session_id() returns the session id for the current session or the
empty string ("") if there is no current session (no current session id
exists)."
So, something like this will do.
<?php
$sid = session_id();
if ( $sid == '' ) {
// No session started yet.
} else {
// Session has been started.
}
?>

Hey Shelley, maybe I can help you understand Sessions. When you start a
Sessions PHP creates a Session ID. This is then used to create/Store
information in a file or in a database. The configuration of this is in
your php.ini file. If this file you can change where the session is
saved as well as other options. A simple way to use Sessions is with
cookies with the session.use_cookie = 1 in the php.ini file. However, if
the client doesn't allow cookies there is a second way;
session.use_trans_sid = 0 there are a few problems however, it creates a
security risk.
Anyway, I hope this opens a little on how sessions works. If you wish to
learn more about sessions go to http://us2.php.net/session or
http://w3schools.com/php/php_sessions.asp

Hi All,
I using html_options smarty tag to output an associative array in select
drop down.
Here a sample associative array:
array(5) {
["CN-PEK-KEJ"]=>
array(1) {
[198]=>
string(7) "TechTst"
}
["IE-DUB-GAS"]=>
array(2) {
[177]=>
string(10) "store room"
[39]=>
string(10) "TechStop 2"
}
["UK-LON-BEL"]=>
array(1) {
[88]=>
string(16) "TechStop-LON-BEL"
}
["IE-DUB-GOR"]=>
array(1) {
[159]=>
string(10) "TechStop 1"
}
["US-NYC-9TH"]=>
array(1) {
[194]=>
string(12) "TestTechStop"
}
}
and the syntax I have used to output this was:
{html_options name='locationId' options=$locations
selected=$selectedLocation}
where in I assign $selectedLocation with one of the options after selecting
them.
Even after everything being right, the option thats been selected is not set
but it again goes back to show the first option after submit.
Looks like either smarty misinterprets this selected option or is there
something wrong from my end.
Cheers

yeah, I just ran into the same thing yesterday evening with mcrypt and
rijndael_256.
encrypting went fine, decrypted string had a lot of nulls at the end. so
I too had to use trim() on it.
