I would also like to hear suggestions on how to fix this mess:
$r = funcA ( funcB ( funcC ( $p ) ) );
if funcB() / funcC() fails, how would you fudge/abort the calling
function in the chain?
One may think that funcA and funcB just check their parameters list
for being "error" arrays, but the problem i foresee is that depending
on the context of the $r= call, desired behaviour may vary at any
stage in the funcA -> funcB -> funcC chain.

I would abort it by embedding the mess in a try.. catch statement, then
throwing an exception. Teus.

error_log - for logging errors
throw Exception - for show stoppers
try/catch - for when you can handle a potential show stopper
custom error logging / messaging can easily be achieved with something
like this:
<?php
class Messenger
{
private static $_messages = array();
public static function addMessage( $string )
{
self::$_messages[] = $string;
if( $string instanceof Exception ) {
echo self::report();
}
}
public static function report()
{
return implode( PHP_EOL , self::$_messages );
}
}
set_exception_handler( 'Messenger::addMessage' );
Messenger::addMessage( 'little error report 1' );
Messenger::addMessage( 'little error report 2' );
Messenger::addMessage( 'little error report 3' );
throw new Exception( 'this will stop the script' );
// exception will kill the script; if you comment it out
// or wrap it in a try catch then you can keep going..
Messenger::addMessage( 'little error report 4' );
// try catch exceptions and report them like this..
try {
throw new Exception( 'we could catch this' );
} catch ( Exception $e ) {
Messenger::addMessage( $e );
}
Messenger::addMessage( 'little error report 5' );
// and when your done just echo it out or save it or..
echo Messenger::report();

I have extended the standard exception class to send me an email
whenever an exception occurs.
I treat all errors on the live system as exceptions. They shouldn't
occur. If they do, I've missed something.
But at least I'll get a near instant notification of the issue, along
with the stack and all the params involved.
Very useful.

I did that once. Once being the operative word... :-) Ended up with
tens of thousands of emails one morning. At first I thought... "Wow,
maybe my popularity has grown somewhat". But it hadn't.

Oh. BTW. Thanks for RMail (previously known as htmlmimemail5 if anyone
else is interested).

I have something similar... a cron job that checks the error_log file
every 10 minutes and sends me the contents if any exist. I also set a
special header so I can be sure it's not spam and appropriately route it
into my mail folder maze, Much less spammy :)
Cheers,
Rob.

Hmmmm... I've always gone with "a wise man learns from his mistakes".
Not that I'm saying I'm wise or anything... just seems a good goal to
shoot for :)

So, no documentation AND bugs!!! Gee. I really wouldn't want to rely
on that code base!

I want to generate credential zip file for user on the fly with
zipArchive and render it for download, so I created following code
---------------------------------------------------------
$zip = new ZipArchive();
$filename = '/tmp/xxx.zip';
if ($zip->open($filename, ZIPARCHIVE::CREATE)!==TRUE) {
throw new Exception();
}
if($zip)
{
$zip->addFromString('xxx.xx', $fileString);
}
$zip->close();
$fileString = file_get_contents($filename);
unlink($filename);
$this->getResponse()->setHeader('Content-Type', 'application/zip');
$this->getResponse()->setHeader('Content-Disposition','attachment;filename=xxx.zip');
$this->getResponse()->setBody($fileString);
-----------------------------------------------------
it works, but I think creating the file in memory is a better
approach, so I changed the 2nd lineI(using php 5.2.0) to
$filename = 'php://temp/xxx.zip';
then the php just won't archive the file and the file downloaded is
just a plain text file.
so
question 1, how to create zip Archive file in memory on the fly and
download it (I don't have to save it on disk)?
question 2, if there is no way to create in memory, is it safe to just
unlink() the file?
thanks in advance.

According to http://docs.php.net/manual/en/wrappers.php.php, it looks
like you should be using ...
$filename = 'php://temp';
That's it.
The actual file name is not your job.

Hello,
I am working with the SOAP package of PHP and I am trying make a connection
from a hosted website to a server in our office.
I can get to the server perfectly fine from within our office, but I cannot
connect from the eternal site.
I have checked and I am certain that the firewall for the server is open.
When I attempt to use the login page that I have created for the website I am
getting the following error message:
Connect Error to XX.XX.XX.XXX:8080
Where XX.XX.XX.XXX mask the actual ip address of the server. I have tried to
interogate all the values that soap_fault documents that it can return and
the only information I have been able to find beside the above message, which
is the $errorstring, is that my $faultcode = "HTTP".
The information that I am getting is very cryptic. if I include our ip
address when I search I get no results. If I put in connect error :8080 I get
millions of meaningless results.
Can someone please help to figure out how to get more meaningful information
from soap_fault for this problem so that I can figure out how to fix it.
Thank you
