Hello everyone,

I just need your assistance on how to unsubscribe from PHP mail list. I have tried all the automated approach but no luck. The system keeps rejecting my "unsubscribe" request. I get more than 200 unsolicited mailS on PHP daily that do not mean anything to me because I did not subscribe to it in the first place - not a computer guru.

Any help to lead me to effectively unsubscribe will be well appreciated. My mail box has been overtaken completely by this service which is of no value to me.

One way to approach this could be that You set a start visiting time in a session, when the user enters the site. If he/she is still online after let´s say 5 minutes, then a Javascript window is popped up. Notice that popup blockers kill more than 50% of all popups (a stat I implemented a couple of months ago on 2 heavily visited sites in Denmark).

The popup window access a script, that for instance could be made with fopen(), fwrite(), fclose(), which opens, reads and write to a txtfile, that has the name of the session_id

On the admin site, where the employee is suppose to see users, You can read all txt files in the dir with opendir() and readdir(). Of course You will need to have a clean up script to get rid of or move ended chat sessions.

I hope this will give You enough ideas to start Your project :-)

Every code is... if You don´t use Your head, the outcome will be...?

If U no nothing about SQL, I use a database to a counter, I get a piece of code from a friend "alter table counter auto_increment = 1"; and I´m curious to see, what it does?

Or better: I put my query in a link like <a href="db.php?q=select+*+from+customers">show customers</a> and I´ve got NO clue about the settings in the mysql db, so this gets "funny"
<a href="db.php?q=delete+from+customers">show customers</a>
<a href="db.php?q=drop+table+customers">show customers</a>

*whistle*

This _was_ an issue in a company I worked for, along with queries like:

Select blablabla FROM t1,t2,t3
WHERE customers LIKE '%$s%'
OR name LIKE '%$s%'
OR domain LIKE '%$s%'
OR email LIKE '%$s%'
OR log LIKE '%$s%'
AND t1.id = t2.t1_id
AND t1.id = t3.t1_id

Horror!

Kind regards

Richard has a good idea about using mysql to do this. Some things I have
not tried, but might also do for you is php's flock
http://www.php.net/flock . Or go to http://www.php.net/fopen and search
the page for "lock" (no quotes). The example you might want was the 4th
instance of that word that I found.
<?php
#going to update last users counter script since
#aborting a write because a file is locked is not correct.

$counter_file = '/tmp/counter.txt';
clearstatcache();
ignore_user_abort(true); ## prevent refresh from aborting file operations
and hosing file
if (file_exists($counter_file)) {
    $fh = fopen($counter_file, 'r+');
    while(1) {
      if (flock($fh, LOCK_EX)) {
         #$buffer = chop(fgets($fh, 2));
         $buffer = chop(fread($fh, filesize($counter_file)));
         $buffer++;
         rewind($fh);
         fwrite($fh, $buffer);
         fflush($fh);
         ftruncate($fh, ftell($fh));
         flock($fh, LOCK_UN);
         break;
      }
    }
}
else {
    $fh = fopen($counter_file, 'w+');
    fwrite($fh, "1");
    $buffer="1";
}
fclose($fh);

print "Count is $buffer";

Is it possible to let the OS handle the collisions?

For example:

That's what you *THINK* you want to do :-)

But what happens when *TWO* users hit that same script at exactly the
same time.

At best, you get:

User1 User2
Reads 9 Reads 9
Writes 10 Writes 10

and when you should have 11, you've only got 10.

[aside] "My amp goes to 11!" [/aside]

But it's worse than that: It's entirely poassible that your script,
instead of having two users write "10" one after the other, will have
two users both trying to write "10" at EXACTLY the same time.

The result is comparable to a head-on collision between two trains.
Your file is TOAST.

This is why so many early "hit counter" scripts back in the day were
always getting messed up and reset to 0.

What you really want, almost for sure, is an SQL database with
"sequences"

You have to forge those in MySQL by making a table with auto_increment.

You *can* use http://php.net/flock, but even that is a Bad Idea, because
flock under Un*x is self-imposed -- If some *other* program/script/user
decides not change that file and doesn't use flock, well, they're not
STOPPED from doing that.

flock is therefore all too subject to human fallibility when you
re-work, re-write, or add more code to your system.

The SQL guys have worked out this problem, in all respects.

This is one of those things that SEEMS so simple that turns out to be a
hell of a lot more involved than you thought at first. So it goes.

Luis: if the OS handled the read/write collisions then you could just
file_*_contents() and be done with it. Unfortunately it's not that
simple in any situation where you might have more than one person trying
to access the same PHP page at *exactly* the same time.

Make it a little more clear what you want. Is this an already existing
image, or one you are trying to create? If it already exists then you
want to use an img tag.

<?php echo '<img src="/path/to/image.jpg" />'; ?>

Not sure you need to use image creation now.

All you seem to really want to do is display an <IMG tag, or not, based on
the if.

if (...){
echo "<img src=images/myimage.jpg>";
}

Thanx Jim,

Unfortunaly some e-mail clients send the headers in ways the

so I won't post it here)

Greetings again,
Thanks to richard for pointing out a good way to
devle
into the source. It appears after browsing through the
source that the ' ' (space) is encoded to '+'. Also
the
characters '_', '-', '.' do get special treatment.

Obviously, this works great in the scenario where the
cookie is set by the PHP/Server and retrieved by a
PHP/Server.

Since the encoding is not mandated by the spec, I
guess I cannot fault PHP for doing what it does. But I
am curious as to what led to the design decision to
encode ' ' to '+'.

Thanks to richard and others for all the help.

You can do something like this...

function subEndWord ( $string, $start, $max ) {
        $string = substr ( $string, $start, $max );
        $string = preg_replace ( "/\s\w+$/", "", $string );
        return $string;
}

Untested, but should work. Tinker with the RegEx to perfect it.

I'm not sure these lines are the ones that are triggered from PHP.
These seem to be Tomcat/JSP related (mod_jk)

I just tried it again, and it looks like I included too much
information. This is all I got this time:

[Fri Mar 11 11:55:04 2005] [notice] child pid 31108 exit signal
Segmentation fault (11)

So even though the other messages came through at the same time, it
might only be the last one that is significant.

Sorry if this is too DB oriented.

PHP 4.3, MySQL 3.23

I've got a somewhat complex search of a MySQL database I'm trying to make.
(At least it's complex to me.) And I'm wondering if it's better to try to
handle it in MySQL or to split it up into multiple processes using PHP.

Essentially, I have three tables: vendors, products, and a join table for
vendors and products:

VENDORS
-------
vendorid INT
vendorname VARCHAR
vendorcategory VARCHAR

PRODUCTS
--------
productid INT
productname VARCHAR
productcategory VARCHAR

JOINS
-----
xid INT
xproductid INT
xvendorid INT

I want to be able to do a keyword search of sorts with a list of vendors as
the result. However, I want one value from a form to be used to search
three columns in two different tables: vendorcategory, productname, and
productcategory. Of course, the join table would have to be used to make
sure that the product names and categories that match give corresponding
vendors.

There's probably some method of using MySQL to do this with one query, but
it's beyond me. And experience tells me that sometimes it's easier or
better to use PHP (or even necessary to use PHP) to get the results how I
want them, often splitting complex queries into two parts.

Any suggestions?

Thanks.

Before we go through all of this, why isn't SQLite an option? It is in
by default as of PHP5.0.0 so if the server is / will be PHP5 soon then I
would go that route.

Jason -

Yea, I saw that, but for this I have to assume that they're running 4.x,
else I most definately would go the route of SQLite :/

Hi,

I've built this little regular expression to test wether an e-mail
address is valid or not:

if(eregi
("^[a-zA-Z][\w\.-]*[a-zA-Z0-9][a-zA-Z][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z][a-zA-Z\.]*[a-zA-Z]$",
$email))
print ('valid email)
else
print ('Invalid email');

ok, now i want to use this in a filling form web page scenario.
I have this forms with its fields to be filled and when it gets to the
e-mail address textbox, i want to check if the address is not well formed.

So i did (notice the "!" before the eregi):

if (!eregi
("^[a-zA-Z][\w\.-]*[a-zA-Z0-9][a-zA-Z][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z][a-zA-Z\.]*[a-zA-Z]$",
$email))
{ send a warn to the user telling the e-mail address is not correct}

Well, if the first block of code works pretty good saying if an address
is valid or invalid, the second one, when the data from the filled form
is checked, always says the adress is invalid.

I thought the "!" would adapt the confition to its new scenario, but,
well... as i've told you, it isn't.

Any ideas of how to solve this, i.e., being the regular expression (and
it is), what do i have to do to get only the invalid adresses ?
In short, i only want to trap the invalid ones.

Any help would be apreciated.

Warm Regards,
Mário Gamito
