I guess you're looking for array_pop(), it pops the last element off
the end of the array. Look it up in the manual to convince yourself.

The message 'extension not found' means that PEAR couldn't find the mysql db
extension. Hmm. In cases like this, create a phpinfo.php file as documented on
this list and see what shows up. Or, you can type at the command prompt: php
-i, then look for the MySQL extension in the output.
Also, you neglected to tell us what OS you are running, etc.

Hello!
I wrote this skript, but gettext returns only the english string.
I could not find a bug at bugs.php.net, so I think I forgot something.
I have Debian Linux, PHP Version 4.3.4 and Gettext 0.14.1 (PHP and Gettext
as debian pakages)

setlocale(LC_ALL, 'de_DE');

i18n/de_DE/LC_MESSAGES/messages.mo now
// Print a test message

Did you restart apache after creating your mo file ?
Look at the first comment on http://ca3.php.net/gettext
You might be facing this issue.

You are right, thank you.
But there where another mistake, too. My system doesn't like "de_DE", it
wants to have "[EMAIL PROTECTED]".

Hi,
I had really bad headaches with gettext some time ago
and since then I decided to no longer use it. It's unreliable on
heavy loads (mixed english + translated texts), moving the scritps to
another machine means more headache, it relies on system calls which
are not "isolated", which means scritps can step on each others toes.
My advice is stay away of gettext. Try some DB framework for
translation; it definetely performs better and more reliable.
Or, if the site is small you can rely on included files.
Cheers,

Thanks for your advice!
I have tested the script on the Webserver, and fortunately it works!
I am using gettext because of the po Files. With programs like KBabel it is
no problem to translate them. The second reason is the Plural. I hate
sentences like '1 File(s) found!'.
I could not notice a loss of performance yet.

John,
The long expanation is I'm indexing 2000 records to make a list of each author, and
which record I can find them in. It's a bibliography thing. I want to do this, but I
don't know how to code it:
$array();
$myconnection = mysql_connect($server,$user,$pass);
mysql_select_db($db,$myconnection);
$news = mysql_query("select id,AUS from $table");
while ($mydata = mysql_fetch_object($news))
{
$tempauthors = explode(";", $mydata->AUS);
foreach ($tempauthors as $singleauthor)
{
-------having trouble here--------------
add $singleauthor and $mydata->id to $array
-------having trouble here--------------
}
}
mysql_close;
-------having trouble here--------------
foreach ($array as $single_AUS, $single_id)
$sql = 'insert into $db.$table2.($single_AUS, $single_id)';
-------having trouble here--------------
mysql_query($sql)
It's a little more complicated than that, but advice on coding this much would help.
John
P.S. my condoleances to New York today. Can't believe it was 3 years ago already.

Maybe you want this:
while ($data = mysql_fetch_assoc($news)) {
$sql += "INSERT INTO newtable VALUES ($data['AUS'], $data['id']);\r\n";
}
If you nevertheless want save the data in array you can use a
two-dimensional array $authors:
$authors = array();
while ($data = mysql_fetch_assoc($news)) {
$authors[] = array('AUS' => $data['AUS'], 'id' => $data[id]);
}
..
foreach ($author in $authors) {
$sql += "INSERT INTO newtable VALUES ($author['AUS'],
$author['id']);\r\n";

I seriously recommend using .= on strings instead of +=. += DOES work,
that's true, but it's not INTENDED to be used on strings, rather to be
used on arrays and numbers.
If you nevertheless want save the data in array you can use a
two-dimensional array $authors:
$authors = array();
while ($data = mysql_fetch_assoc($news)) {
$authors[] = array('AUS' => $data['AUS'], 'id' => $data[id]);
}
..

Thanks. As a newbie, something I like to try also is making a second file with phps as
the extension.
Sometimes reading my code in colour helps me see things better. Sometimes I forget a
semi-colon ";" and will see the problem immediately.

So save yourself a lot of time and get a colorful editor like vim or
editplus or something.. :)

You overwrite the first Cache-Control command, use:
header("Cache-Control: post-check=0, pre-check=0", false);
Now both Cache-Control commands are being sent.

I'm creating classes that rely on the presence of other classes that I've
created. Does PHP5 provide a way to specify these dependencies or a way to
check these dependencies when the class is instantiated? For example, class
Automobile would fail to instantiate if class Tire wasn't available.
I know the __autoload feature of PHP5 could be used to flag an error like
this:
function __autoload($class_name) {
if ([EMAIL PROTECTED]("$class_name.php")) {
echo "Error: Unable to load $class_name.<br>";
}
}
This solution may work to some degree, but it doesn't tell me which class
depended on the missing class, which would be helpful in troubleshooting.
Also, it seems like you'd want to check dependencies first thing, rather
than getting part way through the application before having an error occur.
What do you think? What approaches do you guys use on this?
Thanks,
Ed

What you can do is something like this:
function __autoload($class_name) {
static $_stack = array();
// push the calls of autoload here
array_push($_stack, $class_name);
if ( [EMAIL PROTECTED]("$class_name.php") ||
!class_exists($class_name, false) ) {
var_dump($_stack);
$_stack = array(); // reset it
echo "Error: Unable to load $class_name.<br>";
return false;
}
// pop the stack
array_pop($_stack);
return true;
}

Hi Curt =)
This didn't seem to work. The stack stuff just ends up dumping the value of
$class_name. Also, why check to see if the class exists on line #8? Isn't
PHP calling __autoload already confirming that the class doesn't exist?
I'll include copies of the two scripts below. Here's information on the
scripts that might help explain things.
The first script is being saved as Test.php. It includes a class called
Test.
The second script is being saved as test2.php. This script has a class
called ClassDependent. It depends on the Test class.
I'm trying to address two situations are being addressed here. What if the
file Test.php is missing for some reason. And, even if the file is present,
what happens if the file / class hasn't been loaded?
In my opinion, if class Test is missing, it makes sense to know up front.
It provides a sort of checks and balances. Otherwise, the class doesn't
show as missing until there's an attempt to load it. I can easily see
deploying an app without realizing there's a problem until someone happens
to use some osbure feature that depends on the missing class.
Maybe I'm being paranoid (opinions? - be nice :P hehe), but once reason I'm
looking into using OOP is to reduce bugs and I'm just looking at possible
pitfalls. It would be nice to hear how you guys handle this with PHP-based
apps that you deploy.
I know that I could just create a list of files belonging to the app and
check to make sure that they are all present when starting. It seems like
there could be a lot of overhead in maintaining something like this. It
also seems to make sense that you'd want classes to define their own
dependencies for portability. What do you think?
All of this kind of leads into why I'd like autoload (or some other tool) to
indicate which class ran into a problem loading another class. In the
examples below, it helps troubleshoot things if the error message tells me
that ClassDependent was unable to load class Test. Hehe Having the error
message tell me which line number would also be super cool, but maybe that's
not possible.
Anyway, I look forward to hearing what you guys think.
Thanks,
Ed

I'm creating classes that rely on the presence of other classes that I've

check these dependencies when the class is instantiated? For example, class
Automobile would fail to instantiate if class Tire wasn't available.
PHP5 does not, but PEAR was created specifically to solve this problem.
All you need to do is package your modular classes as packages, and
then people can use the pear installer to enforce the dependencies prior
to runtime. Then, at runtime, all you have to do is assume they are
there, as the user can't install your class without the presence of the
others (well, they can, but it requires some monkey business and they
would have to know that it failed)

Hey!
I think you used header() after put out some data or php installed on server
as CGI. Because send header possible only if php installed as apache module.
You can use custom function which use javascript for redirection. But it
works if browser of client support javascript:
function redirect(path) {
echo '<script type="text/javascript">window.location='.path.'</script>';
exit();
}

Not so - I've used header('Location: http://www.xyz.com/'); with PHP
as a CGI binary under both Apache 1 and Apahce 2 without problems.

How can I enable PHP5's native SOAP, without
presumably compiling PHP5 from source? I don't see an
extension for it in php.ini

This should work as long as php is installed properly:
extension=php_soap.dll

Add to php.ini
Extension=php_soap.dll
I didn't see a line in php.ini to uncomment, but I found a page that
confirmed this:

I'm doing a project on a server with an old version of PHP -- 4.0.6 on
Apache 1.3.22 on FreeBSD and I'm having a problem with session
variables. From code in a script that receives a post:
-----
session_start();
$HTTP_SESSION_VARS["m_name"] = get_magic_quotes_gpc() ?
stripslashes($HTTP_POST_VARS["m_name"]) : $HTTP_POST_VARS["m_name"];
-----
Then later I can successfully echo the posted value with:
-----
htmlentities($HTTP_SESSION_VARS["m_name"])
-----
The posted value is shown as expected, which means the session variable
is set, right? At the end of the receiving script page I have a link
back to the form where the values were posted from, and in the original
form I check for session variables in order to re-populate the form
with them if they're present:
-----
session_start();
$m_name = isset($HTTP_SESSION_VARS["m_name"]) ?
$HTTP_SESSION_VARS["m_name"] : "";
-----
Then in the original HTML form field:
-----
<?php echo($m_name); ?>
-----
But $m_name == "" and the field is blank.
The same code works as expected on a different server running PHP 4.3.8
on Apache 1.3.31 on Linux. I think I'm stuck with 4.0.6 for this
project. I'd appreciate any suggestions on what I should check/advice
on using $HTTP_SESSION_VARS.
