You can not specify the window parameters (a popup) without using
Javascript.

You are correct, tough. You could load a new page asking them to confirm
(I do this a lot with scripts that delete something - "are you sure?"),
but not in a popup window.

Mathias:

Well then, how about this?

You can create a "uniquely" named id by using:

$unique_id = md5(uniqid(microtime(), true));

and then use that name as a folder for each person submitting scripts OR use the unique id as a suffix for their cms file. Either way, it should stop persons from overwriting cms files.

I would also suggest that you keep track of these id's in a dB. If you are still concerned about two people having the same unique, then you could search the dB to see if the recently created id exist. If it does, then generate another one.

I use a similar method for making sure that the images I upload have unique names.

Wouldn't they still be able to overwrite each other?
I don't think I expressed myself clearly. The point of the protection is
to keep the scripts from overwriting each other on purpose. It was a
protection that would make it posible to upload scripts, even if you
were not completly sure they were safe.

Hmm, a couple of things. Do you get it base64_encoded or decoded? You're
using "decode" as both terms so it's confusing for us.

Does the xml feed give you it inflated or deflated? gzdeflate will only
work if it is already inflated with gzinflate.

Can you get the other person to show you the code of how he puts the
image into the xml feed? That will tell you exactly what you need to "undo".

Seriously guys... am I completely missing something important here? An
empty array evaluates as false. The null character evaluates as false.
The STRING "0" even evaluates as false yet a binary zero does not?

Even better yet bindec() doesn't appear to be binary safe so it will
work for a string representation of binary data where the 0's and 1's
are ascii characters but pass it an actual binary string and it always
returns 0.

(sigh)

Someone help me understand this. Isn't this a bug or oversight?

The character '0' (zero) is not the same as a byte with all bits turned off.

(char) '0' = (binary) '00110000' = ord('0') = (int) 48

'bindec' returns the decimal equivalent of the binary number represented
by the binary_string argument. Note the BINARY STRING key word. I'm
guessing a Binary String is a string consisting of the characters '0' or
'1' not bits. Each character is 8 bits, so a binary string is a
sequence of the characters #48 and #49 from the ASCII table.

The 'character' ZERO is written with bits 00110000 in binary. This
binary could be interpreted as either a character or an integer. If the
binary is read as an integer, you'll get INT 48. INT 48 is NOT FALSE.
Casting from string to int to 'binary string' is done even when you
might not want it. Are you sure you are evaluating your binary
'00000000' properly as you claim? Send a sample code, otherwise, see
the following example:

--------------------------------------------------
<pre>
<?php

$zero = (string)'0';
$one = (string)'1';
var_dump($zero);
var_dump($one);
printf("char: %s, ord: %d, byte: %08b\n", $zero, ord($zero), $zero);
printf("char: %s, ord: %d, byte: %08b\n", $one, ord($one), $one);

// string(1) "0"
// string(1) "1"
// char: 0, ord: 48, byte: 00000000
// char: 1, ord: 49, byte: 00000001

$zero = (int)'0';
$one = (int)'1';
var_dump($zero);
var_dump($one);
printf("char: %s, ord: %d, byte: %08b\n", $zero, ord($zero), $zero);
printf("char: %s, ord: %d, byte: %08b\n", $one, ord($one), $one);

// int(0)
// int(1)
// char: 0, ord: 48, byte: 00000000
// char: 1, ord: 49, byte: 00000001

$zero = unpack('C', (string)'0');
$zero = array_pop($zero);
$one = unpack('C', (string)'1');
$one = array_pop($one);
var_dump($zero);
var_dump($one);
printf("char: %s, ord: %d, byte: %08b\n", $zero, ord($zero), $zero);
printf("char: %s, ord: %d, byte: %08b\n", $one, ord($one), $one);

// int(48)
// int(49)
// char: 48, ord: 52, byte: 00110000
// char: 49, ord: 52, byte: 00110001

?>

alrightey then. the binary data itself is actually stored in a mysql
table. (mysql 5.1.9) the relevant part is the following column:

+------------+-----------------
| Field | Type
+------------+-----------------
| bit_string | bit(8)
+------------+-----------------

but of course there are others. assuming there weren't however, data
would be inserted into this table with a queries similar to:

INSERT INTO blah SET bit_string=b'00000001';
INSERT INTO blah SET bit_string=b'00000011';
INSERT INTO blah SET bit_string=b'00000100';

this part appears to work great. i just discovered the bit type in
mysql myself and have been having great fun with it. just in case you
hadn't heard of it reference here: (*please* don't be insulted if this
is old news to you)

http://dev.mysql.com/doc/refman/5.1/en/bit-field-values.html

anyway, when this data is selected from the table the characters are
clearly being represented correctly, they show up unprintable in various
wierd ways and return correct values for bitwise operations. the
problem happens when you try to say:

<?php
// assume this code is part of a method of a greater class that has a
member database handle already initialized...

--- snip ---
$bit_strings = array();
$rh = $this->_dbh->query('SELECT bit_string FROM blah');
if($rh !== false && $rh->num_rows) {
   while($bit_string = $rh->fetch_assoc()) {
     $bit_strings[] = $bit_string;
   }
   $rh->free();
}
return $bit_strings;
--- snip ---

// ok so lets say you call this method and just for simplicity sake (no
its really not anywhere near this simple) *know* that the three values
above are the only things that get returned. lets say we know that we
will have an array of three values, which are the binary 1, binary 3,
and binary 4, we inserted above, in that order. in that case the
following check:

if($bit_strings[0] & $bit_strings[1]) {
// blah
}

//evaluates to a binary 1 and is therefore true, as would be expected,
but this check:

if($bit_strings[0] & $bit_strings[2]) {
// blah
}

// evaluates to a binary zero but STILL counts as true! (go ahead, try
it yourself)

Now two things are worth stating here. First is that its comforting to
see unpack('C',... in your sample code, because my fix for the problem
last night eventually turned out to be:

$bits = array_pop(unpack('C', ($bit_string_one & $bit_string_two)));
settype($bits, 'integer');
if($bits) {
return true;
}

... and though it seemed to work the way i wanted i was previously
unfamiliar with unpack/pack and was worried i was approaching this
entirely in the wrong way. Thank you for that.

The second thing that needs to be said here is simply a re-statement of
the original, this time more verbosely. The list of things in php that
evaluate as false is as follows:

* the boolean FALSE itself
* the integer 0 (zero)
* the float 0.0 (zero)
* the empty string, and the string "0"
* an array with zero elements
* an object with zero member variables (PHP 4 only)
* the special type NULL (including unset variables)
* SimpleXML objects created from empty tags

now, all i'm saying is that if, of all ungodly things, the literal
string "0" and empty arrays evaluate to false, isn't it appropriate to
expect a binary zero to evaluate to false as well? Maybe i still don't
get it. :(

thanks btw, for your time.

Jon,

You are correct about the behavior you are observing, sorry I doubted
your ability/methods. Here is a much shorter example of what you are
trying to do:

<?php
// start with int '0'
$as_int = (int) 0x0;
var_dump($as_int);

// convert into to binary string
$as_binstr = (string) pack('C', $as_int);
var_dump($as_binstr);

// cast binary string as boolean
$as_bool = (boolean) $as_binstr;
var_dump($as_bool);
?>

// int(0)
// string(1) "!~unprintable~!"
// bool(true)

You want to know WHY a single byte of all 8 bits set to '0' does not
evaluate as FALSE. I don't know the answer, but my theory is as follows:

Perhaps binary strings are not a normal everyday kind of string. If you
have a binary string, you probably got it from a binary place like a
file or stream. If you read a file and that file contains one byte and
that byte is all 00000000, then how is that FALSE when you got 1 byte
not 0 bytes. I might believe that a binary string should always be TRUE
if the length is greater than ZERO bytes in length. Since binary files
are not meant to be looked at, perhaps length is all that determines
their truth?

Oddly, if you start with this in the example above:

$as_int = (int) 48;

Then, the is_bool will be false! Ok, now I'm with you about odd
behavior and wanting a better answer ;-) You can't really use the
bitwise operators on your binary string either. From the manual:

    "Bitwise operators allow you to turn specific bits within an integer
on or
    off. If both the left- and right-hand parameters are strings, the
bitwise
    operator will operate on the characters' ASCII values."

I think the best bet would be to unpack the binary string into a format
that PHP will play nicely with. Most likely if you are looking at a
single byte, unpacking as an int is the way to go.

http://us2.php.net/manual/en/function.trim.php
trim: 4.1.0 The optional charlist parameter was added.

$str = "UPDATE tbl_chassis_temp SET country = 'Singapore', city
'SINGAPORE', building = 'Tampines Central 6', other = 'Level 03-40', ";
$str = trim($str, ', ');

Hi All!

I've a MySQL table:

table (id INT NOT NULL AUTO_INCREMENT,

                                    PRIMARY KEY(id));

If I delete a row, say 5th, the id entries are 1 2 3 4 6 7 ... 10.

I wish to keep entries consecutive, that is rearrange the table as 1 2 3 4 5
6 ... 9. How do I go about it?

Simple. Don't.

The whole point of having a numeric primary key is that it is both unique and
constant. If you change the primary key, then you have to change every
reference to it in every other table as well. You've just defeated the
purpose of having a non-user-viewable primary key in the first place. You
may as well just use the msgName field, save yourself a column in the
database, and still have a huge problem with data integrity.

As I said, don't do it. Stick with the numeric ID and don't change it. You
gain nothing by re-naming your entire database.

PHP List,

I have a database of about 120 users. Each weak I send out a newsletter.
So far as I know, it's been working fine for the last couple of years.

Then recently some users emailed me to let me know that they haven't
been receiving all the messages. I added extra output to my script to
echo out the name of each member that got an email sent to them, and I
can now see that only about 50 of them are getting the email.

The only think that has changed that I can think of is that I've
upgraded to MySQL 5.0. However, given the type of problem I'm having, I
don't think it's a MySQL problem, it appears much more likely to be a
problem with my PHP code.

This is the script that sends out the message (edited slightly to take
out irrelevant bits of newsletter content):

- - - -
$count = 0;
while ( $member = mysql_fetch_row($result) )
{
set_time_limit(0);
$subject = "Newsletter subject line";
$mailcontent = "This message was sent to " . $member[0] . " at {$member[1]}
Blah, blah, blah - newsletter content goes here.";
mail($member[1], $subject, $mailcontent, $fromaddress);
$count++;
echo "Newsletter sent to " . $member[0] . " at " . $member[1] . "";
}
echo "A total of " .$count ." emails were sent out.\n";
- - - -

The script actually dies before it gets to the last echo which echoes
the value of $count. It outputs about 50 lines of "Newsletter sent to
usersname at nameemail.com" and then the cursor is stuck in hourglass
mode and the browser is continually waiting a response. It stays like
that indefinitely, and the only way it stops is if I go to another page
or shut down the browser.

I have heard that the mail() function does have limitations on how many
emails it sends out. But I thought it took hundreds, somewhere between
500 and a thousand, of individual emails before it would die. And I also
thought the set_time_limit(0) function would alleviate the problem of
timing out.

Where have I gone wrong with this?

Any advice would be greatly appreciated. Thank you for taking the time
to read this.

Ask your host if they have enabled email throttling. If you're sending
out too quickly, they might be getting cut off by your host and you'll
need to sleep() between each email being sent.

Is there any easy way to "trim" or pick out the none decimal values in a
numric value? Like:

1,333 = 1
5,667 = 5
12,145 = 12
15,997 = 15

Thanks // Jonas
