[PHP] Fork and zombies
I periodically run a script that makes a call against a remote API, which
takes some time to return. In an attempt to increase thoroughput, I decided
to investigate using pnctl_fork to spawn off multiple processes to make the
call, since the slowest part is the network part of it (and waiting for the
server response). I ended up writing a script that did this:
$pid = pnctl_fork();
if ($pid == -1) {
die('could not fork');
} else if ($pid) {
echo parent $pid\n;
return;
} else {
// make API call
}
While this works, it unfortunately leaves behind a zombie process every
single time. I could rewrite this to instead call fork multiple times, then
wait on all of them to return, but as my system is currently architected,
the easiest way would be to fire and forget for this script. Does anyone
have any ideas on the best way to do it? The other way I've done this is to
use exec(php foo.php) and redirecting stdout and stderr to /dev/null.

You need to call pcntl_wait() or pcntl_waitpid().

Right, but if I do that, then the parent has to wait until the child
completes before it exits. Is there any way to have the parent exit before
the child but prevent the zombie process for existing?

INSERT a

that got

connection-specific, so
you'll always have your own value. You can then save it to
reuse,
either
as a session variable or (more easily) as a hidden field on your
form.
Thanks, Jerry,
You hit the nail on the head.:)
To refine my problem (and reduce my ignorance),here's what is
happening
on the form page:
There is a series of INSERTs. The first inserts all the columns of
book table except for the id, which I do not specify as it if
auto-insert.
In subsequent tables I have to reference the book.id (for
transitional
tables like book_author(refers authors to book) etc.
If I understand it correctly, I must retrieve (SELECT
LAST_INSERT_ID()) after the first INSERT and before the following
insert; and save the id as a string ($id)...e.g. $sql = SELECT
LAST_INSERT_ID() AS $id
I need clarification on the AS $id - should this be simply
id(does
this have to be turned into a value into $id or does $id
contain the
value? And how do I retrieve it to use the returned value for the
next
$sql = INSERT ... - in other words, is the id or $id available
for
the
next directive or do I have to do something like $id = id?
I'm trying to figure this out with some trials but my insert
does not
work from a php file - but it works from command-line... that's
another
post.
Here's how I mostly do it (albeit simplified):
$query = INSERT INTO `sometable`(`title`,`content`)
VALUES('$title','$content');
$result = mysql_query($query);
$autoId = mysql_insert_id($result);
$query = INSERT INTO `another_table`(`link_id`,`value`)
VALUES($autoId,'$value');
$result = mysql_query($query);
No need to call another query to retrieve the last inserted id, as
it is
tied to the last query executed within this session.
Ash
www.ashleysheridan.co.uk
For some reason or other $autoId = mysql_insert_id($result); just
does
not work for me... Yet some of the data is inserted correctly...
I did find that it does not work on tables that are empty... so you
can't start with an empty table. I entered data it still did not
work.
I tried on another duplicate database... doesn't work.
I have checked double checked the database, I have added checks
to see
what is returned and the returns are 0 or null - as I get different
responses for slightly different functions.

connection-specific, so
you'll always have your own value. You can then save it to
reuse,
either
as a session variable or (more easily) as a hidden field on your
form.
Thanks, Jerry,
You hit the nail on the head.:)
To refine my problem (and reduce my ignorance),here's what is
happening
on the form page:
There is a series of INSERTs. The first inserts all the columns of
book table except for the id, which I do not specify as it if
auto-insert.
In subsequent tables I have to reference the book.id (for
transitional
tables like book_author(refers authors to book) etc.
If I understand it correctly, I must retrieve (SELECT
LAST_INSERT_ID()) after the first INSERT and before the following
insert; and save the id as a string ($id)...e.g. $sql = SELECT
LAST_INSERT_ID() AS $id
I need clarification on the AS $id - should this be simply
id(does
this have to be turned into a value into $id or does $id
contain the
value? And how do I retrieve it to use the returned value for the
next
$sql = INSERT ... - in other words, is the id or $id available
for
the
next directive or do I have to do something like $id = id?
I'm trying to figure this out with some trials but my insert
does not
work from a php file - but it works from command-line... that's
another
post.
Here's how I mostly do it (albeit simplified):
$query = INSERT INTO `sometable`(`title`,`content`)
VALUES('$title','$content');
$result = mysql_query($query);
$autoId = mysql_insert_id($result);
$query = INSERT INTO `another_table`(`link_id`,`value`)
VALUES($autoId,'$value');
$result = mysql_query($query);
No need to call another query to retrieve the last inserted id, as
it is
tied to the last query executed within this session.

For some reason or other $autoId = mysql_insert_id($result); just
does
not work for me... Yet some of the data is inserted correctly...
I did find that it does not work on tables that are empty... so you
can't start with an empty table. I entered data it still did not
work.
I tried on another duplicate database... doesn't work.
I have checked double checked the database, I have added checks

PJ, you *really* need to read up on the *basics* of the PHP language.
Please buy a good book on the subject, or search php.net for arrays
and read and understand what is there.
To summarize, $book_publisher is an array, as you can tell by the
square brackets after it. Its first index is book IDs. So in the
expression $book_publisher[$row['bookID']], $row['bookID'] is the
index for one of the members of the array. It could be 5 instead, as
in: $book_publisher[5].
Likewise, $row is an array. When you see an expression like
$array['something'] or $array[1], the value being represented is
actually the value at that index of the array. If you have an array of
letters called $alphabet, it might look something like this:
indexes: 'a', 'b', 'c', 'd', 'e'
contents: 'alfa', 'bravo', 'charlie', 'delta', 'echo'
So if you had an expression like: $alphabet['d'], it would actually
represent the value 'delta'. Read the above until that's clear.
In the case of $row['bookID'], it's just a value at the 'bookID' index
of the $row array. It could be '1234', '55-345' or whatever.
So $book_publisher[$row['bookID']] is the array member at the
$row['bookID'] index of the array.
Lastly, since an array member can also be another array, you can have
multidimensional arrays. In your case, it's:
$book_publisher[$row['bookID']][]
Notice the last set of open and close backets on the end. That tells you
that $book_publisher[$row['bookID']] is an array member which is
actually another array. But empty open/close brackets have a special
meaning. You will only find them (meaningfully) on the left hand side of
an equation. They mean that you're adding whatever is on the right side
of the equation to the last position in the array. So
$book_publisher[$row['bookID']][] = $row['publisher_id']
Says that the $row['bookID'] member of $book_publisher is an array, and
that you're adding a member on the end whose value is
$row['publisher_id'].
Depending on your mental abilities, you may have to draw the arrays on a
sheet of paper to make it make sense. Also remember that arrays can be
indexed either numerically or associatively or both. A numerically
indexed arrays would have just numbers for the indexes. An associatively
indexed array is what you have above, indexed not necessarily by number
but possibly by strings or whatever.
All this is fundamental to array processing under PHP and used
constantly. So learn it and learn it well. If my explanation is
insufficient, then look it up and fully understand it before you go on.
Otherwise, you'll take one step, ask a bunch of questions, take another
step, ask a bunch of questions, and generally make yourself a nuisance.
You're essentially asking professional programmers to tutor you for free
when you really should take the initiative and read/study the subject
yourself. It doesn't matter if you don't really want to *be* a
professional programmer at the end of this. You have to approach it as
though that's your goal.
Let me put this another way. Assume you're a professional chef. You get
paid lots of money to cook food for people. You've had years of
education and practice and get paid accordingly. Suddenly one day,
management sends you some wet-behind-the-ears kid who's flipped burgers
at McDonalds, and you're supposed to teach him how to cook like you do.
Every time he cuts a shallot or dices an onion, he asks you a bunch of
silly questions he should know if he had gone to culinary school like
you did. You're busy. And the questions are things like What's the
difference between a teaspoon and a tablespoon?. How come I have to
dice onions? Can't I just throw them in the pot? And you know that the
only reason the kid is there is so he can learn to cook some stuff to
impress his girlfriend, who's gonna dump him in three months anyway.

Well, first, it shouldn't do anything because you have parse errors that
should stop the script.
On your very first line you haven't surround the email in quotes (only
one quote). Then later in the line $dbc =
mysqli_connect(hostet',UN,'PW','DB') or die('Error connecting to MySQL
server'); you're missing a quote before hostet.
Second, you look for empty vars and if they are empty then you echo that
they forgot to enter them but go on to send the emails anyway.
Then you loop through a database result and send to everyone and then
you send another one to the last person you just sent to.
Try this:
?php
$from = 'em...@email.com';
$subject =$_POST['subject'];
$text =$_POST['body_of_mail'];

Hi Paul - I appreciate your assistance,

Produces something like:
COUNT: 39 (final previous)
model: MODEL 22-A
34 - condition: good
33 - new
32 - old
305 - new
Etc...
Paul - this seems to work (if I understand you correctly...), but I would
like to have a title line (above) say:
MODEL - 22-A - COUNT: 39
At the top ... Currently - the way I have it wants to display the *count
BELOW* the line items - (when it's done counting) .. And I fooled with this
line;
echo 'br/ COUNT: '.$count.' final previous'.'br/br/';
Which 'sort of' shows at top - but doesn't really help the 1st item...
Q: any way to improve this?

Thanks for your reply. Some of what you are saying is a little ahead of my
lessons, but let me address as best I can. The script worked fine in the
previous lesson where I was to send emails from my DB, this lesson is to
kill the email from being sent if empty.
On your very first line you haven't surround the email in quotes (only
one quote).
That worked fine with the single quotes and is listed in the book that way.
Then later in the line $dbc =
mysqli_connect(hostet',UN,'PW','DB') or die('Error connecting to MySQL
server'); you're missing a quote before hostet.
The single quote was deleted when I was sanitizing the code to post here,
but it is in the code...sorry.
So the jist of what you are saying is to add die after the if
statements...but they are not in the book

Well, first, it shouldn't do anything because you have parse errors that
should stop the script.

one quote). Then later in the line $dbc =
mysqli_connect(hostet',UN,'PW','DB') or die('Error connecting to MySQL

Second, you look for empty vars and if they are empty then you echo that
they forgot to enter them but go on to send the emails anyway.
Then you loop through a database result and send to everyone and then
you send another one to the last person you just sent to.
Try this:
?php

Each one of these probably going to scan the whole table because the
approved column isn't going to be selective enough to use an index.
You might be better off doing:
select approved, count(*) from comments group by approved;
then in php separating them out:
while ($row = $DB-frow($q)) {
switch ($row['approved']) {
case null:
$waiting = $row['count'];
break;
case 0:
$deleted = $row['count'];
break;
case 1:
$approved = $row['count'];
break;
}
}
$total = $waiting + $approved + $deleted;
Duh, of course, thanks :)

Try replacing the die line with:
die('You forgot to enter a subject and or text in the body!br /Click
the back button.br /');
This is just an example using the code that you posted as a learning
exercise.
Your original IF said: if $subject is empty, then evaluate the next if
$body_of_mail is empty, if so, then echo 'You forgot to enter a subject
and or text in the body! br /' THEN execute the rest of the code which
returns records from the db and then loops through them and send an
email to the addresses from the db query.
I just added a die() which kills the script execution IF the fields are
empty and an ELSE, which is evaluated if the fields are NOT empty, that
does the db query and email.
In a real world example, instead of die() you might reload the form and
display a message, so that the user can correct mistakes and resubmit.

Well, I was dubious about my answer, based on the idea that someone else
might have a better way. However, it appears not.
So what I would do is probably, instead of echoing stuff immediately,
I'd just append it to a string until you're ready to output a total
line. Then output the total line, and immediately after, output the
string you accumulated while counting. Make sense? The whole point in
the first place, as I recall, was to avoid umpteen database queries. So
what you're doing is to load it all up at once and then let PHP do the
heavy work instead of the database. But the total you want is only
available after you've processed all the records for that item/model. So
if you want it to come first on screen, you'll have to accumulate all
your detail lines as you go. Then when the total is ready, output that
and then output all the stuff you've accumulated. I don't know any
better way to do it.
If it's still not clear, let me know.

Thanks Paul for the explanation. It really does help and iis much

I must respond to your chastisement of me, because i believe you may not
be aware of the fact that most books on programming really suck. I have
had my taste of enough of them to not bother. The kinds of things that I
am trying to do just cannot be learned from a book or from most of those
tutorials one finds on the Internet.
How do you think *I* learned this? Back in 1974, when I hooked up my
high school teletype via an acoustic modem to the school district
mainframe and logged in for the first time, I had one choice for
programming languages: Mainframe (Dartmouth) BASIC. So I bought a book
on the subject, still in print today, called Basic Basic. Thus I
learned Pascal (Turbo Pascal). Thus I learned C (Kernighan and Richie).
Thus I learned Linux (man pages). Thus I learned Perl, Python and PHP.
*All* from books. I didn't have anyone to ask. Even when I got a job as
FoxPro programmer, I had only FoxPro books to tell me what to do. If I'd
pestered the other coders by asking them questions about how to do
things all the time, they would have fired me on the spot. I benefitted
there from having programmed in other languages before. FoxPro was
then just another language.

Yes, programming books *can* suck. And most assume you know more than
you do.
I benefit because I programmed in C before I programmed in PHP, which is
virtually C for the web. And my C benefitted from knowing Pascal before
that and BASIC before that. Multi-dimensional arrays are part and parcel
of Pascal and C. So encountering them in PHP was no big deal. Syntax
varies from language to language (in Python, you don't do $arr[] =
'blah'; you do arr.append('blah')), but the concept is the same. Once
you know the concept well, the syntax is relatively simple to learn,
unless you're trying to learn Scheme or something (;-}).
They are either moronically
basic of sadly flawed or outdated. It's something like the
do-it-yourself-wikis... any dolt can put of whatever they think.
That's the downside of the net, of course. The upside is that there are
great people, like yourself and a number of other who have been very
helpful and who are willing to share their knowledge.
Anyway, I find very little in the tutorials on the web that goes beyond
total basics.
You're not looking hard enough. I've found help with a great many
esoteric (edge case) problems by searching on the net. You can't just
decide Well, all the books suck and the net sucks, so I'll just ask
someone who knows. That's why they write books. So people don't have to
use up all the time of people who know, by asking them masses of
questions. The people who know are busy producing products. Professors
and teachers get paid to teach people things, not productive
professionals in a field. You're lucky the professionals are willing to
spare the (free) time to explain what already plainly exists in books.
Learning PHP5 is a crappy little O'Reilly book for anyone who's
programmed in another language and wants to learn PHP. But it's
perfectly fine for a non-programmer learning PHP.
Don't get me wrong. I have nothing against you personally. And I'm more
than willing to share my knowledge with others in general. I allows me
to clarify my concepts and gives others an opportunity to dispute what
I'm saying. And of course, it helps others get it, when I know it's
sometimes hard to figure out a way through. But I've done enough years
of tech support and instruction to recognize the symptoms I'm seeing
here.
I'll let other people hold your hand from now on. And when they get
enough of it, they'll chastise you as well.

Well, I was dubious about my answer, based on the idea that someone else

So what I would do is probably, instead of echoing stuff immediately,
I'd just append it to a string until you're ready to output a total
line. Then output the total line, and immediately after, output the
string you accumulated while counting. Make sense? The whole point in
the first place, as I recall, was to avoid umpteen database queries. So
what you're doing is to load it all up at once and then let PHP do the
heavy work instead of the database. But the total you want is only
available after you've processed all the records for that item/model. So
if you want it to come first on screen, you'll have to accumulate all
your detail lines as you go. Then when the total is ready, output that
and then output all the stuff you've accumulated. I don't know any
better way to do it.
If it's still not clear, let me know.
Thanks for your help PAUL - with your explanation I got it working - Yipee!!
Like this
==
$product = '';
$productlast = '';
$show='';
$count = 1;
while ($a = mysql_fetch_assoc($getall)) {
if ($product != $a['model']) {
if ($productlast != '') {
echo 'br/br/br/MODEL: '.$productlast.' TOTAL COUNT '.$count.'
br/br/ '.$show;}
$show='';
$count = 1; // resets count for each new model
$product = $a['model'];
$show = $show . $a['model'].' '.$a['id'].' - loc:
'.$a['condition'].' 1br/';
}
else {
$count++;
$productlast = $a['model'];
$show = $show . $a['model'].' '.$a['id'].' - loc '.$a['
condition'].' 2 br/';
}

Thanks Paul for the explanation. It really does help and iis much
appreciated.
I must respond to your chastisement of me, because i believe you may not
be aware of the fact that most books on programming really suck. I have
had my taste of enough of them to not bother. The kinds of things that I
am trying to do just cannot be learned from a book or from most of those
tutorials one finds on the Internet.
How do you think *I* learned this? Back in 1974, when I hooked up my
high school teletype via an acoustic modem to the school district
mainframe and logged in for the first time, I had one choice for
programming languages: Mainframe (Dartmouth) BASIC. So I bought a book
on the subject, still in print today, called Basic Basic. Thus I
learned Pascal (Turbo Pascal). Thus I learned C (Kernighan and Richie).
Thus I learned Linux (man pages). Thus I learned Perl, Python and PHP.
*All* from books. I didn't have anyone to ask. Even when I got a job as
FoxPro programmer, I had only FoxPro books to tell me what to do. If I'd

I understand what you are sayig and I am quite impressed with your
knowledge and experience.
Just to justify my position and by the way before I forget I hope that
there will be others who will benefit from my frustrations as some of
the help I have received has been quite high level and that, obviously,
I did not find on the web.
As to intensifying my search on the web, well, little by little I
stumble onto some stuff that is helpful but the amount of time I spend
looking and thinking is beyond normal human endurance. And the rewards
from searching are extremely minimal.
Where can you find the kind of stuff that you and Jim Lucas have offered
is not to be found easily if at all on the web. And don't forget how
miserable searching has become on Google. The others, I don't even
consider and don't have the time.
I'll try harder to understand the array but there is a lot that simply
is not clear...
I keep analyzing the
Re: [PHP] Fork and zombies
While this works, it unfortunately leaves behind a zombie process
every single time.
You need to call pcntl_wait() or pcntl_waitpid().
Right, but if I do that, then the parent has to wait until the child
completes before it exits.
No it doesn't - just call pcntl_wait() with WNOHANG to check the status
of a child.
Hm, so now I'm not so sure what's happening. Before trying your suggestion,
I ran my script again without pcntl_wait so that I'd have a baseline for how
many zombie processes are being created, and it turns out that I don't think
any are. Previously, I was doing
ps aux | awk '{ print $8 $2 }' | grep -w Z
to find zombie processes, and it turns out that they existed from before, as
the count didn't change after I ran my script. That leads to another
problem, though, in that the resource for the database doesn't seem to be
available for the parent after the child exits. Here's pseudo code for what
I'm trying to do:
foreach ($things as $thing) {
info = getInfo($thing); // uses a db connection
makeApiCall(info);
}
makeApiCall(info) {
$pid = pcntl_fork();
if ($pid == -1) {
die(could not fork);
} else if ($pid) {
// parent, return the child pid
echo child pid $pid\n;
return;
} else {
// do some api calls
exit;
}
}
But after I spawn off the process, getInfo($thing) errors out sometime later
on with an invalid query error, because I think the db connection is
gone. I thought adding exit in the child process would be enough, but
that doesn't seem to work, I still get the same error. Why would the child
process affect the query in the parent process, especially if I exit in the
child process?
Following your suggestion, I also tried pcntl_wait in the upperlevel
function, but still had the same problem.
Thanks for any insight,
Waynn
