Not for reasons you think. The (or "image/jpeg") is going to
evaulate as TRUE, so your expression will always be true. For
example:

var_dump((bool) "image/jpeg");

You should really consider using the fileinfo extension, or mabey
even http://php.net/getimagesize. The ['type'] information
can't be trusted to be what it says it is.

I have a dedicated server in the states.

I need to send about 8000 emails (once off). There pretty small +- 5KB.

so I want to write a php script and run it from the command line in the
background. I was thinking of sending 50 emails then waiting 90 seconds
then sending again.

the same script gets run by cron every 90 seconds and just sends 50 emails.

What do you recommend?

Hi Angelo,

Why not send them all in one go? If you want to reduce server load, you
should perhaps adjust the 'nice'ness of the script.

If you do the following:

nice --adjustment=19 ./script.php

Your script will run in the background and use only spare resources.

Because niceness would only affect the script itself and not any smtp
servers it comes across along the way.

renicing would make the script nice to the local computer, but sending
8000 in one go, will overload the remote smtp servers which do not
know the local nice value.

but that will only affect the local machine.

You could adjust the bandwidth using trickle, but to answer the mans
question - it doesn't really matter. Personally I'd perfer the former,
but you have to make sure that your script doesn't time out by setting
some php.ini value(forget the name of it.)

I would send them one at a time. While the script itself could probably
handle sending 50+ at a time, you have to think about the mail server.
Say you have the 8000 emails in an array....

#!/usr/local/bin/php
<?php

// Stuff to get email addresses
// and create message

foreach ( $emails as $email ) {
mail ( $email, $subject, $message, $headers );
sleep ( 10 );
}

YMMV

Thanks to those who have replied so far, yes our main concern is the
smtp server falling over or dying. So to come back to John Nichel's answer:

John, have you done this personally and I assume the effects were
good?? IE everything ran smoothly?

I have done it just as John has described above, though I didn't have 8000
to send. All went well, no hiccups. A couple of things I would mention is
that I seem to remember reading somewhere that the sleep() function on
Windows eats a lot of processor. Not an issue for me since I'm on Linux,
but worth a mention. And the function John suggested above will take over
22 hours to send 8000 emails. Since you say its a one shot deal, its
probably OK.

I use some code just like that at least once a month to send out a
newsletter for a site I run, and it works fine. I'm only sending out
appx 1400 emails though, so I can afford to let it sleep for a longer
period of time. You can probably go lower on the sleep time, but it all
depends on your setup.

A better solution, if you have access to it and your mail server
supports it, is to just inject the whole thing...that way you're not
making a SMTP connection each time.

I don't think the long running script with sleep function is the best
approach to this problem. I would recommend writing the whole queue
somewhere (to database) and run script every 5 minutes, load some not
sent yet e-mails (100), send them and write info (it_was_sent tag) back
to database.

It's always better to not have long running script, you never know what
can go wrong and if it fails somewhere or process is killed or machine
rebooted or something happens, you don't know which emails were sent and
which not. And there's no stupidest thing as sending the same company
newsletter twice to the same client.

What's to stop you from writing this 'sent tag' using the sleep method?
What I wouldn't like about the every 5 minutes cron method is that the
script will run _every_ five minutes regardless if it's sending mail or
not. Not to mention the fact that even with a small number like a 100,
you could still cause problems with the mail server trying to make that
many SMTP connections in less than a second or two.

You computer is full of scripts/programs/daemons that have long
runs...some 24/7. That isn't a problem as long as you think ahead.
With proper logging, I can easily pick up where I left off should the
script fail for one reason or another.

On a Fedora 4 machine running MySQL 4.1 I am having trouble declaring an
instance of a mysqli extension.

class Data extends mysqli {
    function __construct($host, $user, $password, $db = null)

        parent::__construct($host, $user, $password, $db)
        or printf("There was an error (id: %d) connecting to the database:

....

}

$link = new Data("localhost", "user", "password", "db");

This invokes the error "Trying to clone unclonable object of type Data."
However if I create the link with a reference ...
$link =& new Data(....);
...everything works fine.

This error is interesting because it only occurs on the machine mentioned
above, in a Windows/MySQL 5.0 environment, everything works fine without the
reference.

Thanks in advance!

This is because you have the ini option:

I have a news-script on a webpage. Or an eventscript you might call it.
This lists up events thats gonna happen on a given day. ie concerts and
sportsevents.
To get this deleted without having to log on to the adminpage when the event
is over would have been a great relief.

1. Is it just as simple as writing a query that executes and removes news
with yesterdays date?

2. And how should I set it to execute if so?

Just at the beginning of the page with the news is my thought. So that it
checks for the eventdate and erases the overdued ones before it collects the
news.

3. Is there any pitfalls I should be aware of?

I use Mysql for my db of course.

Could someone give me a start on this?

Even simpler, why don't you keep the data instead of deleting it and write a
query for the homepage which only displays events whcih occur in the future?

2. And how should I set it to execute if so?

If you do want to execute a regular PHP script to delete data for some
reason, look into cron (*nix) or task scheduler (windows)

Yup,

DELETE FROM your_table WHERE date_column = curdate() -1;

If you wanted to do that, I'd recommend adding some sort of probability
factor into it, so not all scripts have to run the function.

e.g. 1% chance of cleaning up the database.

<?php
if (rand(1,100) > 99) {
deleteItems();
}
?>

The code is Tony's, so I can't help, I'm afraid. I think you'll find
it's itertwined with his development framework, so I'm not sure how
useful it would be as a standalone in any case.

Hi,

I am trying to create a form on my page. The idea is that for each project
people can select whether they are allocated for scheduling, non_scheduling
or both. Here is an example of my form:

<tr>
   <td><input name="project[44][Scheduling]" type="checkbox"
value="44"></td>
   <td><input name="project[44][Non_Scheduling]" type="checkbox"
value="44"><td>
   <td>Project 1</td>
  </tr>
    <tr>
   <td><input name="project[25][Scheduling]" type="checkbox" value="25"><td>
   <td><input name="project[25][Non_Scheduling]" type="checkbox"
value="25"></td>
   <td>Project 2</td>
</tr>

I am trying to access the arrays in the HTML as follows:

if (is_array($_POST['project'])){
   $fields='';
   $values='';
   foreach ($_POST['project'] as $project_id => $value) {
    $fields[] = $project_id;
    $values[] = $value;
   }
   $i = 0;
   $num_elements = count($fields);
   while($i < $num_elements){
    if(($values[$i]) != 0){
     echo '<br />$i = '.$i.'<br />';
     print_r($fields);
     $query = ("INSERT INTO Allocations (
           User_ID,
           Project_ID,
           Scheduling,
           Non_Scheduling
          ) VALUES (
           '".$user_id."',
           '".$fields[$i]."',
           '".$fields[$i][0]."',
           '".$fields[$i][1]."',
          )");
     echo $query.'<br />';
    }
    $i++;
   }
  }

However I can't access the 'Scheduling / 'Non_Scheduling' part. Can anyone
see where I am going wrong here?

Thanks for your advice

Shaun,

This:

$values[] = $value;

Does this:

$values[] = array('Scheduling' => '44');

Therefore, it must be accessed like this:

$values[$i]['Scheduling'] // gives '44'

But not this:

$values[$i][0] // index doesn't exist.

Cheers,

"Scheduling" or "Non_Scheduling" is an array key.

I tried it with different versions of php5 even a recent CVS of 5.1.x, the

Yes, by just escaping a single line, the "surfaced error" doesn't occur
anymore, however, as of the simplicity of the specific line of code, I
believe the compiler is already choking without that line while errors will
begin to surface with the line included.

Circular references:

Object A has Object B, while Object B has a "parent" attribute which is
referenced back to its parent: Object A

Cross-referenced:

Object A has a child Object X, Object B also has a child, it's a reference
to the very same Object X

The dizzy making thing here? Object B is also a child of Object A, which
appears to be the causing this problem: php still hates references....

At this point we can only speak in hypotheticals. Assuming your code is

cannot begin to know how the compiler is broken.

Cannot use a scalar value as an array In function [fs_sso->edit()] In
file [/include/libraries/footsteps.php] on line [834] fs_sso->edit()

[/structure_edit.php] on line [62]

This error is correct for all but, that the error occurs in fuction
"fs_register_property()" which is called by object "fs_sso" from function
"edit()"

I will now start stripping the code of the affected objects for an example
script, I hope (but doubt) the error will still occur in de example script

attached mail follows:

I've got some example code on what I'm doing, however, as I expected, the
error is gone!

All involved objects were taken from the project, but not related code has
been stripped-off. (Which means that some of that "at code level not related
code" is in fact "related at compiler level". I still suspect references.
Anyway, the code is still a bit rough, I'm going to do some further testing.
The code is useless for debugging, but might give you an idea on what I'm
doing, if you like i could make it available for download.

How long is the code example? Could it not be pasted here or pastebin?

attached mail follows:

Example is still quite large, all database functionality and other arbitrary
code has been stripped. Over 50.000 lines of code have been reduced to a few
hundred. Example can be downloaded here:

http://213.10.83.232/example.tar

Explanation of example:

- When you load index.php, the involved objects will be loaded into your
session.
- If you use the "reset" link, the objects will be reinitialized.
- Continue just reloads index.php, objects will just wakeup from the session
- You can change the title of the fs_ssl object, via the text input
- Underneath the submit button, the current title of fs_ssl is displayed
- The error that occurs in the real project:
On changing (submitting) the title of ssl, the sso->properties array gets
overwritten, this does not happen with this example

Further, just explore the code to see what I'm doing exactly, if you need
more comment on what i'm doing, I will add comments to the example source
code.

As soon as I have several hours of time to spare *cough* I will explore the

1. If the error does not occur with this example the situation you
originally described becomes non-reproducable. If we cannot reproduce the
error we have no chance of offering a solution. As you add things back into
this example code, when does it break?
2. The folks on this list are here to help, but I don't think that anyone
has time to sort through 100's of lines of code looking for what may be a
potential error, without wanting to charge a consulting fee.
3. You have no comments in your example code? Brilliant!

I know that I am being sarcastic here.

I (and others) really would like to help, but I need you to help me (us) do
that. I understand that the code is sensitive (company copyright/work
product issues) and lengthy. I strongly suspect that the application may be
overly complex (based on a quick read through the code) and that you could
accomplish that which you are trying to do without being so obsfuscate. I
also think that you should send the information you have given us thus far
to the PHP-DEV list (http://www.php.net/mailinglists) and see what response
that they have to offer given your assertion that the compiler is broken. It
is more likely that someone lurking that list will be aware of problems like
this where the compiler is concerned.

Happy Thanksgiving!

1. Again, when adding code back nto your example when does it break? That

If I find some spare time in quantities great enough it would have to be

3. Always comment your code. It is not an option. I hear this excuse all of
the time. It is only the fool who does not comment his code, especially code
so complex. Commenting may have helped you more precisely locate the
problem. And how do you know that I do not read Dutch, have a person on my
staff that speaks and writes fluent Dutch, or have access to google
Translate? :) We have an office in Pijnacker!

attached mail follows:

Eric,

everything you have written suggests to me that the problem is in your code
(that may be being caused by changes to the engine, which have either removed
an ability due to the fact that it was dangerous [e.g. reference issues], or
abilities that have been changed because they were deemed wrong)

regardless of whether that is the case or not you are best off by assuming that
the problem is in your code:

1. if its your code you have the power to fix it, which is a better situation
to be in than have to rely on third parties to fix an underlying texchnology.

2. it avoids 'blaming' core developers until such time as you can _prove_ the
engine has a bug.

the last 3 lines are bullshit on all counts (apart from the implied deadline
pressure), do yourself a favor and starting commenting! :-)

I'd be happy to translate for you Jay ;-)

having said that there is no reason to write comments in dutch if your
english is as good as it is, but comments in any language are always better than
none. (assuming the comments actually have some baring on the actual code -
i.e. comments like '// Bill Gates has lots of money' don't really help!)

attached mail follows:

LOL Jochem

Well I sure can't argue with that! (serious)

But with or without comments, the code is broken or breaks something. I've
tracked down the weird bevahiour a little further. Now I would sure like, if
one of you has about 30 minutes time to look at my problem with me, using
VNC and Skype
If you got the spare time I would really appreciate it and as I've been
unable to create some actual reproduce code, the only thing that's left is
looking at the real thing. I'm still sure it's related to the way I use
references, wheter it is or isn't a bug in the compiler, it sure would be
nice to know this particular DON'T about references.

Please let me know
