RELEASE ANNOUNCEMENT
phpDocumentor 1.3.0RC6
Download:

http://www.phpdoc.org

The phpDocumentor team would like to announce the release of version
1.3.0RC6.  This is the last release candidate of version 1.3.0, the
first stable version to be released since 2004.  The 1.3.0 series is a
milestone, and 1.3.0RC6 demonstrates that amply.


Nice to see progress on this - I still much prefer the output from it to 
that produced by doxygen when building developer documentation of a project.

Thanks for the good work!

I believe that if you installed my perror extension:

you would be able to easily print out the error message corresponding
to 11.

 


I can't it's cursed.


I suppose you could be old-school and just use a shell with:
perror 11
but that is not nearly as much fun.

 


That puts something out, but where is the realtion?
Doesn't help.

Re: [PHP] secure upload file

[Wolf]

In Apache's Config:


 Options None
 AllowOverride Options
 Order allow,deny
 Allow from all
 RedirectPermanent * "somewhere else"


By using that and uploading to the upload_dir via another script, you
create a black hole.  Stuff comes in but can't be accessed from the
outside world afterwards.

Your page's problem is entirely a Javascript problem. Has nothing to do 
with PHP:


Try moving the "onchange" from the  tag to the enclosing 
 tag. (It is the value of the  that changes when a 
different  is selected.)


Now for the lecture:

> Is there any problem with trying to call a javascript function from

Yes, it's impossible. PHP is executed on the server. Javascript is 
executed in the browser. So Javascript cannot be called from PHP running 
on the server.


PHP is a document generator. You can use it to generate Javascript the 
exact same way you use it to generate HTML. But the resulting Javascript 
won't be executed till it gets to the browser.


The main problems you'll have generating Javascript from PHP are:
--keeping control of all the embedded quotes.
--keeping control of the embedded logic (and remembering to remember 
that the Javascript part isn't being executed just yet :)

For further clarification, here is how I got it to actually convert, but still 
display the output to standard out:

$img = shell_exec("convert -resize 800x600 /tmp/file.pdf[0] jpg:-");
header("Content-type: image/jpg");
print($img);

Now you can dream up any sort of ideas with GET variables to define which 
image you want.

Later,
Ray

Okay, I'll admit it.  I didn't STFW.  I believe that if I make a seperate 
script to just display the images, and then display them all with .  Of course this is just theory until I try it, 
but I'm pretty sure this is on the right path.

[PHP] Imagemagick Displaying Images

[Ray Hauge]

I have an application that shows thumnails of PDF files in different 
directories.  I have so far decided that I can use "convert" from imagemagick 
to get a .jpg, .png, .gif, etc. to display as the image.  The problem I'm 
running into is that I don't want to save these thumbnails.  Instead I just 
want to take the binary data and display an image with it.  I figure that 
it's possible since you can store binary data in a database and display it 
that way.

an example of what I'm doing is:

convert -resize 800x600 AR-M455N_20060420_130446.pdf[0] -

The '-' makes it display the contents of the image to stdout.  I want to 
caputre that binary data and somehow display the images inline with the 
website.  Is this possible, or am I living in a dream world ;)

[PHP] [RELEASE ANNOUNCEMENT] phpDocumentor 1.3.0RC6

[Greg Beaver]

May 2, 2006
RELEASE ANNOUNCEMENT
phpDocumentor 1.3.0RC6
Download:
http://pear.php.net/PhpDocumentor
http://www.phpdoc.org

The phpDocumentor team would like to announce the release of version
1.3.0RC6.  This is the last release candidate of version 1.3.0, the
first stable version to be released since 2004.  The 1.3.0 series is a
milestone, and 1.3.0RC6 demonstrates that amply.

phpDocumentor is written by Gregory Beaver, Joshua Eichorn and others in
PHP, and works by parsing PHP source code, and generating customizable
documentation in HTML, PDF or windows help file formats.  phpDocumentor
is the premiere auto-documenting application for PHP.  Used by giants of
the industry such as Zend, ez Systems, and the standard auto-documentor
of PEAR, the program is also bundled in popular IDEs such as Zend
Development Environment, PHPEdit, and nuSphere phpEd.

In version 1.3.0RC6, not only is stability at its highest level yet, but
full support for PHP5 features has been implemented, including:

 - documenting classes that extend internal classes (like Exception) or
implement internal interfaces using the Reflection extension.
 - userspace interfaces, abstract classes
 - access control (private/protected/public)
 - access modifiers (final/abstract/static)
 - class and array type hints

To acquire phpDocumentor, either run:

pear upgrade PhpDocumentor-beta

or download your copy from www.phpdoc.org and extract, following
instructions in the INSTALL file.

You do *NOT* want to do this on an auto_increment field in a
relational database.

It's just a Bad Idea in so many ways...

For starters, you're going to need that 'id' field in a bunch of other
tables to relate the two tables -- That's kinda why they call it a
RELATIONAL database.

So if you re-number this table, you have to go through all the other
tables related to this table and update them as well.

You're looking at a cascading nightmare of updates.

THAT is another kettle of fish entirely.

You pretty much just need to manage the numbering on a different
column "by hand"

create table mytable(id int(11) auto_increment, rank int(4));

Queries you will find useful:

//The rank for the new item added to end of list:
select max(rank) + 1 from mytable;

//Queries to move to top of list:
$id = /* get ID of row here */
$rank = /* get current $rank of that row here */
update mytable set rank = rank + 1 where rank < $rank
update mytable set rank = 1 where id = $id

It's easy to mess up and get everything "off by one" but this is not
rocket science to figure out and debug.

Okay, this is not what I understand of mail() if the path to sendmail

The main problem with using mail() for mass emails is that every call
to mail() fires up sendmail, and you can easily swamp your machine.

If the host won't let you do more than X per minute, and you write a
loop to stay within that limit (http://php.net/sleep) then you should
probably be okay.

I wouldn't want to do it for THOUSANDS of emails, but you're probably
going to run into time-delay problems of the mail not being relevant
because of the server-enforced limits before anything else.

I had to do this once for a client, and I'll just paste my code here.

It's crude in many ways, as I don't really know ADOdb well enough to
remember the darn function names, but didn't want to write a second
'connect' script, so I sort of use ADO to connect, and then ignore
ADO.


getAdoDbConnection();
  $dbconn = $init->getAdoDbConnection();
  require 'email_message.php';
  $message_object = new email_message_class();
  $query = "select mail_id, subject, plain, html from mail ";
  $query .= " where autosend ";

No idea what's wrong, but check your Apache error logs (if you run
Apache) to see if you have a child segfaulting at that point.

If so, you can find out more about how to debug here:
http://bugs.php.net/
Search for the "backtrace" link and info on that page.

I believe that if you installed my perror extension:
http://l-i-e.com/perror/
you would be able to easily print out the error message corresponding
to 11.

I suppose you could be old-school and just use a shell with:
perror 11
but that is not nearly as much fun.

We've told you "No, you don't need display_errors = 1" about four

I believe this is just C syntax legacy, although I think you can pass an
argument to a C compiler to raise a warning when this kind of statements
are
found, that can't be done in PHP. Anyway, is just the way
compiler/interpreters are made when a language has a C syntax style, it's
just more efficient for the compiler to do what you're told and don't ask
too many questions (if you mess up and your program is slow or buggy is
your
fault not the compiler's).

Note that the line with just $query; on it doesn't, like, "do" anything.

I suppose in a Zen-like sort of way, it "exists" and all, but, really,

Is there some subtle reason for this not being some kind of syntax

This is not just philosophical minutiae -- Real-world beginners, with
no programming experience, actually type the above (albeit with a lot
more logic and whatnot in between) and then wonder why the query
didn't execute.

It even makes a wild sort of sense to type that, if you presume that a

Does anybody actually USE this idiom in any meaningful way?

Hi Ross,

You can reuse item_id after they have been deleted. So when you delete
item_id = 1, then next time you perform an insert, lookup the lowest
free item_id number and give it as the item_id. That's one small solution.

If you actually want to rank your records by more than just the item_id,
then define a field for each kind of rank you want, or better, add it as
a separate table, like:

board_papers -< rank
* id
* board_papers_fk <-- id from board_papers
* rank_type (example: readability, technicality...)
* rank_no (rank within the rank type)

Then you can order the board_papers after rank as you like!

Just an idea :)

Enjoy,

Does anybody know what causes "pcntl_fork(): Error 11"?

(It's PHP5 and the scripts source is top secret.)


The 11 is from errno.h and it corresponds to EAGAIN.


From the docs for fork()

The fork() function shall fail if:

[EAGAIN]
The system lacked the necessary resources to create another process, or

I think you're kidding. I write web applications all the time and
constrain my line width's to 80 columns. If you are speaking to embedded
HTML code then I can see your problem.. but I use a good templating
system which keeps most html out of my code... and I never use what I
consider to be the ugliest style of all... switching back and forth
between PHP and HTML mode.

Re: [PHP] display_errors off and custom error pages

[IG]

So to use a custom error handler do I HAVE to have display_errors set to 
1 in my php.ini file? This would of course mean I would have to use 
custom error handling across all my scripts.

[PHP] What means "Fatal error: pcntl_fork(): Error 11"?

[Oz]

Hi,

My script dies with the following line (after a few hours running without other 
errors/warnings/notices):
Fatal error: pcntl_fork(): Error 11 in /home/foo/bar.php on line 297

Is there any documentation for "pcntl_fork(): Error 11"?
Does anybody know what causes "pcntl_fork(): Error 11"?

(It's PHP5 and the scripts source is top secret.)

Thanks for your time,
 - Oz

[PHP] I need to Index and to research files PDF

[Carlos Augusto Falcão da Silva]

Good afternoon!!!

I am developing a system of content management through intranet,
for us to manage our documents involved in the system of administration of
the
quality and also the norms of the assemblers etc. I Possess, today, some
500
norms, being about 85% in paper. I already come scanning some and allowing
I access, controlled, through links in the intranet. It is what want to do
with all
them. In other words, scanned in PDF, copy for a paste in the net, I
distribute the
accesses and in a page an index is presented with all of the files. There
is everything calm. The one that I want do now it is to generate an
indexation form and
he/she researches of those norms, through search fields in that you/they are
researched
the occurrences inside of the files PDF. I want to do something (if it is
possible)
similar to the that Coppernic Desktop Search or Google Desktop Search
they do. If you make a search for the software, he gives you all of the
occurrences,
in all of the defined files in the research. For me, it would be a
hand-na-wheel
absurd. I tried to research in the manual, but I didn't get to arrive in a
point
common. I think I didn't get to seek right! : - (

Ah, in time, I am using PHP+MySQL in that content manager. ;) And
all generate my documents in PDF, with recognition of characters (OCR)
of good quality (for Acrobat I make the researches usually!), besides
to define several "metadados" (tag's) in the properties of the generated
documents.


A great hug and I hope to count with his/her help.


Ps.: My English is very poor, therefore, I apologize! I used an electronic
translator as aid. :(

Thank's...

[PHP] Question regarding apc

[Dave Goodchild]

Hi all. I have heard that functions like apc_define_constants and
apc_load-constants are useful in speeding up mass definition of constants
but could someone tell me how many constants you would have to have before
this became appropriate. I am writing an app that loads a number of
constants into the main config file and estimate that there may be 200+
values. Is it worth using the library for this many values?

Ok, after digging through the sources, I figured this one out.  There's 
a 4th parameter to the method:


   xmlrpc_server_call_method

And, the options are all explained on this page:

   http://xmlrpc-epi.sourceforge.net/main.php?t=php_api#output_options

Not only can you set the encoding to UTF-8, but you can also and and 
remove the whitespace which was also nagging me.

"IF" the brackets are set up in a logial order.

Re: [PHP] php mysql problem

[Wolf]

Depending on your needs, here is another tack to think about (I know,
everyone else will be gasping and running for air...)

A few years ago I had to make a shopping cart.  I had an archaic system
that would not share information with my web/db server, so I had to
write a query to dump the products, quantity, price levels, etc out of
it to a CSV file.  I then used perl to get the file, reformat it into
SQL files, then run an empty of the table and recreate with all the data
that I just got off the server.

To get past the naming conventions and such and NOT lose any linked
tables, I did my joins and such off the product ID.  The Caveat to this
was that the products (even those we no longer sold) stayed in the
system for about 6 months, and by the time we were ready to purge those,
the orders were saved and could not be deleted (PDF and as saved data)
so that was never a problem.

That solved the product counts for me (since the bosses were a bit anal
about having accurate product counts and such) and kept that table tidy.

Customers was not so tidy, nor wore the other tables.  But you can only
work with what you can do.

In short, unless you have a very good reason and safety checks to keep
your data from getting lost from other tables, you might need to rethink
why you want that.

If you want to chew the fat and talk design, shoot me a message off-list
and I'll be glad to help.

 They are not that expencive anymore.(The CRT ones)
 Even on 1024x768 you see LOTSA code.


I frequently code on smaller monitors -- laptop, ancient desktop,
stripped-down flat-panel monitor that fits inside a rack-mount 2-RU
shelf in my sound booth...

I can't really lug a 19" monitor all over, and there's no room in my
sound booth for it, what with the amps, sound boards, computer, CD
duplicator, etc.


If cost is not an object, consider a MacBook Pro -- it runs windozes 
and has a 17 inch monitor, which provides 1680 x 1050 resolution. 
Nice monitor for a laptop.

Ross:

I am sure that the advice of everyone here and on any mysql list will 
be NOT to do what you are asking. You're looking at the ID as if the 
order of that field means something, it shouldn't.


However, to provide you with what you asked for, please review:

/* Renumber the Existing Sequence
alter table mytable
drop id,
add id int unsigned not null auto_increment,
auto_increment = 1;

Keep in mind that by doing this, your dB should remain flat -- you 
cannot successfully renumber a relational dB without also considering 
all the dependant tables, which is not trivial.


HTH's more than it hurts.

Re: [PHP] Re: php mysql problem

Exactly - I don't think you really understand how a relational database
works. The ids are retained as they may relate to records in another table.
Internal sorting order is of no relevance at the application level. I think
you need to rethink your design a little.

Really can't imagine why you wanna do something like this. What's the use
in reordering a database. It's just a database. you can sort it in any way
you like.. gaps or not.. Sounds to me the sorting is only done on screen.

This is pretty easy done with PHP not in the database itself.

when you cock your structure up.  I can't remeber the last time PHP told me I 
had a syntax arror at the end of the file -- if I've got unbalanced start/end

slap bang in the target area.

Yeah true. : and endif is nicer.

[PHP] Problem with ftp_rmdir

[PJ]

Hello everybody,

I'm using function ftp_rmdir to create some aplication and for testing 
I've used following sample from php.net


if (ftp_rmdir($conn_id, $dir)) {
   echo "Successfully deleted $dir\n";
} else {
   echo "There was a problem while deleting $dir\n";
}

Command really removed specified directory, but stopped script as well. 
So there is no more output about "Successfully deleting" of this file 
after line with ftp_rmdir


When I tried this:
$x=ftp_rmdir($conn_id, $dir);
echo "start $x end";

the second line with echo wasn't put to output... It seems like there is 
exit function after ftp_rmdir...


Does anybody knows, what goes wrong??
Thanx

Pavel

Yes - still lovely, readable, compact code.  And dead simple to spot you've 
failed to indent the "else" section after "// where am i?". (Apart from all

Uurgh -- curly  brackets -- I see curly brackets -- and, aargh, horrible curly 
brackets -- eeew, and I think some code, maybe -- but definitely curly brackets.

Yep, nice -- still too many curly brackets, but readable.

Oh my god -- curly brackets and excessive indentation -- and curly brackets.  
Just a mo, where did I put my curly-brackets-and-whitespace-glasses?  Aaaahhh, 
that's better!!

As you might have guessed, I *HATE* curly brackets with a vengeance, which is 
why I eschew both those styles and use PHP's alternative syntax:

  if (...):
 if (...):
   // mmh
 else:
   // oh
 endif;
 while (...):
   if (...):
 // oh

Why do you want to do that? There's no benefit in doing this..
actually it becomes a pain.

You'd need to update not only this table but any field in other tables
that references this one as well (and if you miss one, you have a
completely useless database).

Pretty much any package you find, you'll have to export the

If anyone has seen the amazon dvd rental list where you can swap dvd to 
the top of the list and delete this is what I am trying to achive with

You are mixing up concepts here.  An ID is that, an identifier, and it goes 
with the record from its creation to its deletion.  That's what an ID is for 
(which in most Anglo legal systems is something people is not used to, an 
anthropological curiosity if you wish).  What you are looking for is an 
Order field (which, of course, you can name as you wish, since order is a 
reserved SQL word, I just give the concept of it), which is also numerical 
and that, if you put in your select  like Select * from mytalbe order by 
`order`, id will be used to order records and, if missing, will default to 
id.

Why do you auto_increment them then?

Normally it's very wrong to set back autoincremented values because you 
don't have any reference anymore.


So if ID X is causing an error it could be Article X or Article Y or 
article Z. You don't know because the database is shifting it around.
Add a second field called "sort" or something similiar and let it sort 
on that.

Or give it Article Numbers or whatever.


(b) allow the ids to be changed so the items can change position in the 
list. If I change id 3 to id 1 then everything else shifts down.

update id = id +1 WHERE id > X

Yeh.. expanding on what the others said, you'll have to get your

on a linux box, it should be pretty instant (uses a "socket" type
connection), check logs and anything like spamassassin or other

on a windows box, could be anything from dns, network, firewalls...

I've seen ppl coding like that.

If you indent, you see it as you scroll through without actually

$letztezeit = time();

}
//endlosschleife abbrechen
if ($count > 20) {
$taggefunden = true;
$letztezeit = false;

}
return $letztezeit;

My style:

{

On "first" view i can clearly see what is happening without going

There won't fit your 80 chars per line style. Are you going to strip it 
down to 13 per line now because of that?


Yes you can actually code it that it fits in any small space so that you 
might even see it on a digital watch.


But that fact shouldn't be affecting coding style at all.


I can't really lug a 19" monitor all over, and there's no room in my

Well, first it has to fire up sendmail...

Then sendmail has to accept the email for delivery.

But that should not be 30 seconds...

30 seconds sounds like a network domain-name lookup timeout issue.

Perhaps your sendmail.cnf is not quite right...

What happens if you login as the PHP user and send email from the
command line?

Here's the thing.

You want your error message to not reveal your internal workings of
your web application to the Bad Guys.

You want your web site to look "pretty".

No matter how good you are, nor how perfect a coder you are, there is
always room for SOME way for an error to manage to not happen until
after some HTML has gone "out"

So would it not make more sense to set up your error messages, and
your custom error handler, so that the basic paradigm is to:

  log the "real" error message with internal details for debugging
  print a "nice" error message for the user
  FINISH off any open tags, for a pretty error page
  end the script
> The other question is do custom error handlers

No.

You should run every script through php -l before it ever gets near a
production server.

I frequently code on smaller monitors -- laptop, ancient desktop,
stripped-down flat-panel monitor that fits inside a rack-mount 2-RU
shelf in my sound booth...

I can't really lug a 19" monitor all over, and there's no room in my
sound booth for it, what with the amps, sound boards, computer, CD
duplicator, etc.

What are the reasons of slow mail() (about 30-40 seconds)?


If it takes mail() that long to send the email, it's taking your mail 
server that long to accept the email.


Check your mail server logs.

Hi,

many reasons, but nothing related to php IMHO.
mail relay load, slow reverse dns interrogations for spam, etc.

If your mail runs only on a local or corporate network, ask the mail admin,
otherwise, you have to contact the receiver and ask him the question.

Thanks,

Why should it be a syntax error?
You can do the same stuff in nearly every programming language besides PHP.
It's just useless.
The languages doesn't decide between usless and not useless.
Just between syntax okay and not okay.



This is not just philosophical minutiae -- Real-world beginners, with

more logic and whatnot in between) and then wonder why the query
didn't execute.

It even makes a wild sort of sense to type that, if you presume that a
beginner might not grasp the distinctions between PHP and MySQL and
the relationship yet.

Does anybody actually USE this idiom in any meaningful way?


Well i don't ;P

yes. display_errors merely determines whether php spits out errors
direct to std. out or not (i.e. the browser in this case)

your error handler can do whatever it likes including [conditionally]
outputing a user friendly page.


Perhaps I have misunderstood how errors work in php.

Rafael schrieb:

Huh?!
Show an example. I don't think you will be able to show one.
But this wasted space gives you a lot more insight into the code when 
looking for loops,whiles,functions and such.



A couple of facts of my codding style:
- I tend to always use brakets, so I ignore the fact that single
  lines/actions can be written without brackets,

This is "your" coding style.
But if you work in a team, and somone does use that because it actually 
is a neater way of programming.

What do you intend to do?

- I try not to let lines grow larger than about 100 cols (cannot
  be really done with strings and other thingies, and maybe that
  should remain in the old 80 cols, but it's too litle space), and

Never possible if you write web-applications.
CLI might be possible for that but for web it's a no-go.


- I use a 4 space indentation, and that alone suffices for making
  a block stand clear enough

It's not just about one block.
I've seen stuff like:
if (blah blah) {
do my code!
} else {
oh my god!
}

Well, without indentation it just looks like a bunch of chars.

if (blah blah)
{
do my code!
}
else
{
oh my god!
}

Even without intendations, you can clearly see that it's an if and an 
else here.

The best part here is that you see it when you scroll through your code.
without actually "reading" it.


So, in my case, the code would be something like
  function foo( $x ) {
  // body...
  }
  ···
  $a = foo($b);

Even this is far too blocky to read.
If you have 4000 rows of code and looking for some if or switch (you are 
not sure) it would save you a lot of time searching for it though.


And for your problem with viewing. probably try to get a 19" monitor.

Re: [PHP] instantiate derived class objects from within base class?

[Jochem Maas]

php will not have late (runtime) static binding until at least version 6.
this sucks, it has sucked since 2003, welcome to the club of people who think
it sucks :-)

how to hack around this issue:

abstract class A {
protected abstract function foo();
public static function bar($c = null) {
$x = new $c();
if ($x instanceof self) {
$x->foo();
}
}
}

class B extends A {
public static function bar($c = null) {
return parent::bar(__CLASS__);
}
protected function foo() {
echo "hello world";
}
}

...and any number of variations of that hack - all of which are horrid.

Any class that contains at least one abstract method must also be

Make 'A' abstract:
abstract class A

Sorry for the poor example.  I did catch that after submitting my post, 
but it didn't really matter.  Adding abstract to the class doesn't solve 
the problem.  Here I do as you say and still get the error:


-- 8<  8<  8< --

// defines foo() as it should, but base class doesn't know foo exists
// when it references self()
class B extends A {

// show how broken things are
B :: bar();
?>
-- 8<  8<  8< --

Output:
A
*Fatal error*: Cannot instantiate abstract class A in *.../demo.php* on 
line *11


The problem is that when method bar() is invoked on class B statically, 
class B is complete ignored.  Since bar() is only defined inside class 
A, the B :: bar() call seems to be translated into a call of A::bar() 
and class B is no longer addressable.


My expectation is that when I call an object, the search for a method or 
property should start at the bottom-most derived object and work it's 
way up the dependency tree.  This doesn't happen, though.  It appears 
that any class can only reference base class and inherited methods and 
never derived methods.  Perhaps this is only symptomatic when referenced 
statically?

Wow- didn't know about auto_prepend_file. That is a great setting-

also apache has the ability to set a custom handler for 'real'
500 errors. the apache directive is something like:

Sounds like a parse error (using the code above will give you that).

Try it in a htaccess file:

(I think).

You can't use ini_set because a parse error breaks the whole script
and it's not executed, so you need to change this value before the
script.

You need to set this flag in a htaccess file because that gets processed 
before a php script does.


If you are getting a parse error on this script, setting this flag in 
the script won't do anything - the script won't execute at all.


By setting this particular option in a htaccess file, that gets 
processed before the php file does, so if you have a parse error, it 
will say "parse error in file X on line Y" or something to that affect - 
so you can move forward. You can test this manually yourself:


php -l /path/to/file.php

so you could download it to your test server, run that - see what's 
going on.


You could also be triggering a php or apache segfault (in which case 
none of this matters) - are you able to check apache error logs to see 
what's going on from that side of things?



If you take out your custom error handler, do you still get a blank 
page? That will tell us something at least..

You do not need, nor even want probably, ob_start() just to be able to

Yes- blah, blah was just a nicely formatted and helpful error page that

At the moment I have display_errors off and the above script does not

.htaccess, if it is on, will do this, and not require you to remember

That is correct.

It is too likely to expose too much information to Bad Guys.


i don't want error messages on any of my

I thought I might be able to do this by setting an error 500 header with 
 php using the header() command.




Whoa.

Okay, now we are in a different kettle of fish...

I dunno that you CAN force a "500 server error" from within PHP...

I guess there ought to be a function for that somewhere, but I've
never noticed it...

It would probably be documented or linked from or discussed in the
User Contributed notes at http://php.net/header though, if it does
exist.

Would you settle for a nice HTML output like:

An error has occurred. Please try again later.

Because that's pretty much a no-brainer with the error handler -- But
you have to actually output that.

I think your basic problem right now is the assumption that PHP exit()
with no content output would somehow constitute a 500 server error.

It doesn't.
[shrug]

There's nothing inherently "wrong" with the webserver returning a
totally blank document, really.  Well, okay, by strict definitions of
HTML w3c standards, it's not valid HTML.



Good point- web standards are the way forward!



But it's also not a 500 error either.

As far as Apache is concerned, the document is "fine" and returns a
200.  It just happens to be an empty/blank document is all.



Blank pages aren't that helpful to a user though.

Many thanks for your help.
