Re: [PHP] dynamicly generating a transparent truecolor image

[Peter Vertes]

If you want to create a transparent image don't forget it must be a 
GIF.  At least that's what my graphics guys have been telling me all 
these years :)

That's entirely an Apache question, not PHP... unless of course you 
were hoping that $file was a PHP variable (which can't be done, because 
the rewrite happens before PHP parses anything).

Try an Apache list, and modify your query to:

rewrite:
http://username:[EMAIL PROTECTED]/protected/archive/(.*)
to:
http://miningstocks.com/protected/archive/$1
The rewrite is EASY, but I've never dealt with domains and http auth

[PHP] spelling without aspell/pspell?

[Justin French]

Hi,

I just found a really nice set of javascripts for spell-checking a 
textarea before submitting, which is really nice, BUT is shell_exec()'s 
to aspell, which neither my host or my staging server has installed.  
It works with both PHP and Perl too.

There's a demo here:
http://www.netjs.com/speller/
What I'd like to know is if there's any other PHP-oriented solutions to 
spell checking that I might be able to integrate (with a fair amount of 
hacking) into this solution -- or perhaps a complete solution that 
doesn't require any compiling or libraries exists

Grr.that's *not* the problem.  IE saves JPGs just fine, so long as they

I don't think you "hook up" Dreamweaver to anything in the way that
Frontpage "hooks up" to an IIS server. With Dreamweaver (I think) it's

Re: [PHP] pass output of php scripts through command line program or cgi

[Ray Hunter]

on the commandline you need to have the php executable on your
path...then run 

php -f [filename]

so 

php -f index.php

that will do it for you.

[PHP] pass output of php scripts through command line program or cgi

[Paul William]

Hi,

I want to run the output of all the php scripts running on my apache
server through a command line or CGI program. I do not want to modify
any of the php scripts.Has anyone done this? Is this possible?

For example (this is a stupid example and I am not using it for this):

The output of "index.php" is:


...




then that output is run through "addfooter" (a command line script)
which results in:


...

The footer is inserted here.



Then apache outputs the above html.

Any ideas?

Thanks

Paul

Are you using the same user in both cases? The use of LOAD_FILE()

that the user has the 'FILE' privilege.

So you have a PHP file that does (for example)



And you want to retrieve it's results, i.e. the "Hello" string?

Like someone else said, you need to ask this on a VB list. You need to 
determine how to run a program from within VB to run php from the

Well, first your error is because you have $i++ on that last line. It 
should be separated like someone else mentioned. Second, using 
"['obj[$i]']" as the key is not going to work because $i is not 
evaluated between single quotes.

Third, you really need to change how you do all of this and understand 
arrays a little better.

First thing to do is instead of naming things "txtObj1" and "txtObj2", 
etc, name them "txtObj[]". Name every one of them that. Now, when the 
form is submitted, you'll have a $_REQUEST['txtObj'] array containing 
all of your data. $_REQUEST['txtObj'][0] will be the first value, 
$_REQUEST['txtObj'][1] will be the second, etc.

To save that in the session, you can simply do:

$_SESSION['txtObj'] = $_REQUEST['txtObj'];

Now, $_SESSION['txtObj'][0] is the first one, $_SESSION['txtObj'][1] is 
the second, etc.

Any time you're naming things _1, _2, _3, etc, you're doing it the hard 
way instead of using an array.

Hope this helps.

From within a PHP file, you may use exec() or passthru() to execute an 
external program and return the results to the PHP script.  Seems to me 
like VB should have something similar to execute a PHP script (perhaps 
through HTTP or something).

At any rate, I think you would probably need to ask this question on a 
VB mailing list, since they may be able to help you better.  If your PHP 
script just echos something, then you'll need to find out what VB 
function there is to execute the PHP script and grab the value that is 
echoed.

Re: [PHP] mysql question

[Christian Calloway]

Hey Mike,

That is almost exactly what I am doing. I have a table, lets say
"product_fields" which describes each characteristic/field of a product
(with N possible fields). A definition of a field includes, its name (as the
customer see's it), its type, a named-reference to the field in the data
table, and of course the id of the particular product.  The "products_data"
table is composed of fields sequentially labeled from f1 to fn, and contains
the actual data. The only difference being that I am creating a new
"products_data" table for each product (so something like
"products_data_$productid"), as opposed to storing all field data in a
singular large table. So the real question is, is it favorable to have one
large table with N number of fields (products * fields), or N number of
smaller tables (N products). I have absolutely no idea, but I will do some
digging myself. Thanks for the help

Are you using the same user in both cases? The use of LOAD_FILE() 
requires
that the user has the 'FILE' privilege.

[PHP] readfile() and 401 pages

[Vince LaMonica]

Hi all,

I'm attempting to use readfile() to redirect the user to a .htaccess
protected page:

https://www.foo.edu/cgi-bin/stats/awstats?config=more.foo.here";);
?>

The stats/ directory is .htaccess'ed. [and the URL is even longer, with a
lot of other options tagged onto the awstats call]. I would like to be
able to redirect users to a simplier URL:

https://www.foo.edu/stats/site

and have the 'authorization required' browser dialog box pop up when going
there [like it does when they visit the long/normal URL].

Instead, what I'm getting back is a PHP error stating that HTTP/1.1
Authorization Required in line 2 of the above page. Does readfile() not
pass along 401s to the browser? I know I can do an alias in apache's
setup, which is what I plan on doing if readfile() can't be made to work.
But I am curious if this is a limitation or design in readfile().

TIA,

/vjl/

Is there any way you can save state?  That is, can you keep track of who
got the last one, and use that to determine who should get the next one?

Otherwise, why not just rand() between 1 and 2?   rand(1,2) will, on
average, give you as many 1s as 2s (like flipping a coin).  There will
likely be runs of 1 or 2, but over time, doing rand() with two possible
values versus rand() with 501 values will not be significantly
different.

In fact, since there is one more odd than even between 1 and 501
(inclusive), you will be getting slightly more odds than evens with that
range than you will with a range of 1 and 2.

Also, which PHP version are you using?  If before 4.2.0, you should seed
the random number generator with srand().  If you are using 4.2.0 or
greater, and still seeing non-random behavior, I don't really have an
answer.

This worked.. somewhat.. here is what I want to do though.

I have two people checking the same email address. I want to break up the
emails 50/50 to each person. What values can I put into the random number
generator so that I can get closer to 50/50. I just set up a test page with:

$rand = rand(1, 501);

echo $rand;

if ($rand % 2 == 0)
  echo "even";
else
  echo "odd";


and I'm getting a lot more evens than odds, so the one person would get more
emails than the other. Is there any substitution to rand that I could use to
get one message to go to one person, then the next to the other? I'd like it
to be as close to 50/50 as possible.

any questions, let me know

Thanks,
Jake

What is on line 24?



Try this:

while ($i <= 5) {

Are you using the same user in both cases? The use of LOAD_FILE() requires

The above outlines a scheme which is workable. Could you describe the steps 
you took to implement said scheme which lead you to the conclusion that "It 
actually does not work" ?

My spontaneous reaction is to agree with you. On the other hand, are 
SOAP or XML-RPC over
HTTP any more secure in principle? You would need some kind of 
authentication, of course,
unless you just love exposing your code.

It's a weird concept, but I was trying to give the guy who started the

he has a good reason for doing it. Maybe the people who implemented this

You should have all the files you need to include located on your web

Yes, I don't know why you would want to keep them on a remote server.

is, it's crystal clear. When I read the whole explanation the first
time and was slightly confused already, it was like a wandering through
a foggy night. This sentence, for instance:

"If the target server interprets the target file as PHP code, variables
may be passed to the included file
using an URL request string as used with HTTP GET. "

I read "as used with" as meaning that "this is not quite the same thing
as an HTTP GET", whereas
in fact it is an HTTP GET. And thinking about it now, I realize that it
could hardly be anything else.

Which also means that the phrase about interpreting the file as PHP code
is slightly misleading, since
presumably the same comment would apply to a JSP or any other dynamic
Web page, as long as its *output* is PHP
code.

I think that's enough linguistics for now.

No need to explicitly state "true" and "false".  Just negate the result
of your modulus operator, and take advantage of the fact that "0" is
false, and "1" is true:

function isOdd ($value) {
  return !((int)$value % 2);
}

Yep. The modulus operator (%). Your number mod 2 will be 1 if it is odd
and 0 if it is even.

http://us4.php.net/manual/en/language.operators.arithmetic.php

if ($your_number % 2) {

Is there no other way to protect your (non PHP) files than through

Put the files in a directory somewhere outside the DocumentRoot of the
web site in which the PHP code lives.  Have the PHP code do whatever
"authentication" you want (even if it's just collecting an email
address), and upon success, use file() or readfile() or include() or
file_get_contents() or equivalent to pull the file contents from their
location on the server.
Alternately, if you aren't able to create directories or access files
outside the DocumentRoot for your site, you can create an unbrowsable
storage directory protected with a .htaccess file.  If the filesystem
permissions are correct, your PHP script will be able to read content
from that directory, because PHP code isn't subject to .htaccess rules.
 



It actually does not work.  I am trying to load a PDF file.  I've tried 
to load it from a protected directory loading it with headers, but this 
fails if the protection is on.  Does this make sense to you? 

Unfortunately, I do not have access to the .htaccess file (I am on a 
shared server where I am not the administrator) and I can not store 
documents outside of my http document directory.

RE: [PHP] Syntax Error -> This is WEIRD!

Yes that is true. But I would strongly recommend against doing that.

You should never include anything over HTTP. Its extremely messy, 100%

You should have all the files you need to include located on your web

Yes. I read the manual which provides no clear explanation (I suspect 
that whoever wrote it didn't actually know how it works). So I decided 
to test it. It does exactly what you say it does. I made an include file 
like this:

';
?>

If you inlude that using HTTP, it outputs "Hello world!"

Seems like a strange thing to do, outputting PHP code on a Web page, but 
it's not without conceivable usefulness.

I included part of your original message in here because it must've been 
a part that I skimmed over.  I didn't realize that you meant the entire 
httpd was stalling.  During that 30-45 seconds, no site pages will load 
at all?  What about after the 30-45 seconds?  Does the page that caused 
the stall continue processing, or does it time out?  It sounds to me 
like Apache is rebooting itself.

There're several factors here that need to be addressed: 1) is it a code 
problem (if so, what code is causing the problem and what's the 
error--perhaps check Apache's error log); 2) is it only happening on one 
page, several specific pages running similar code, or random pages; 3) 
does the code connect to a database (if so, what kind of database)?

I think you need to try to address these issues before you can continue 
debugging.  As it stands, it could be a problem with your code, with 
Apache, with a database, etc.  There're really no leads (that I can see) 
to give us a clue as to where the problem is.  Your best bet is to check 
the Apache error logs and see if an error is being generated and saved 
there.

Perhaps someone else could offer some better suggestions than I?

Re: [PHP] mysql question

[Miles Thompson]

Christian,

I did a bit of digging in the MySQL docs to try and find the limits on 
number of fields in a table, etc. Didn't have much luck. I would not worry 
about thousands, or even hundreds of thousands of rows in a table for two 
reasons. First MySQL is becoming a heavier-duty database, and second, when 
the proper indexes are used it is blindingly fast at retrievals. Apparently 
the database engine also handles a large number of tables quite well.

When tables will be multiplying like bunnies, as you posit here, I foresee 
major code headaches.

I've thought about following type of design but have never implemented it. 
Might it work in your situation? Maybe this is what you are already doing, 
and I've just  relabelled it. If so, please accept my apologies.

Have standard tables for the basic stuff.: company, with co_key, address 
fields etc; products with prod_key, co_key, prod_name, etc.

Have two other tables, let's call them prod_descriptors and prod_data. 
We're violating one of Codd's principles here because the prod_data table 
has meaningless field names, just f1, f2, f3, f4 ... fn. How you sort out 
which data types to use is your business.

Prod_descriptors contains the meta information which makes prod_data 
useful. Its fields, at a minimum, would be prod_key, prod_characteristic, 
prod_data_field. For a given prod_key "M56H" there would be a record for 
each product characteristic which you have to track, and the field used in 
prod_data.

This may be a somewhat extreme example, as it is highly likely that there 
are a common characteristics for all products, so things would not have to 
be totally generalized. This design is also somewhat wasteful of disk 
space, but MySQL does a remarkable job, internally, of conserving space so 
it is used efficiently. The thorny issue of which data types to use in what 
columns hasn't been addressed either.

The crunch is whether or not you can ask questions of these tables and 
fetch the data you need.

[PHP] PHP Apache Build Problem

[pw]

Hello,

I am trying to build php-4.3.3 into apache_1.3.28 as a module.
I configure php

--with-apache=/apache/source/path

and the php make process puts the source for mod_php4 into

/apache/source/path/src/modules/php4/
/apache/source/path/src/include/ap_config.h:77:28: ap_config_auto.h: No such
file or directory
I then configure apache with:

./configure --prefix=/usr/local/apache --add-module=src/modules/php4/mod_php
4.c

The apache autoconf configure script generates a Makefile with no errors.

When I try to build apache with 'make' everything compiles fine until the
build of mod_php4 comes up.

Make complains that it can't find headers:

Not to be a stinker, but why not just do the sorting in your mysql query?

select * from your_table order by clinic_name, doc_name;

If sorting in PHP is what you really need to do, the answer is to not use
array_multisort. Use usort() instead, with a function that compares
arguments based on clinic_name and doc_name (code untested):

function compare_docs($a, $b)
{
if($a['clinic_name'] === $b['clinic_name'])
return(strcmp($a['doc_name'], $b['doc_name']);
return(strcmp($a['clinic_name'], $b['clinic_name']);
}
while($row = mysql_fetch_array($result))
$docs[$counter++] = $row;
usort($docs, 'compare_docs');

In the documentation, I've found plenty of examples to do a 
multi-dimensional sort on one column, but not on two at the same time. 
My advice would be to do this sorting in your SQL statement.  "ORDER BY 
clinic_name, doc_name ASC" would accomplish the same thing.  Then, when 
you're in your while loop, it'll be added to the array in the proper 
order and you won't have to sort the array.

If you hve a close look at the code http://www.serv-int.de/class.session.txt
you will find the session_start() in the constructor of the class prior to
any output.
The thing is, that session_start() calls the user defined session functions
(defined in session_set_save_handler()) and that's what breaks the whole
thing.
This is not a problem of session_start(), I'm pretty sure.
The problem is, the session id is not set in the open function, but it is
set in the read function.

Yes. I read the manual which provides no clear explanation (I suspect 
that whoever wrote it didn't actually know how it works). So I decided 
to test it. It does exactly what you say it does. I made an include file 
like this:

?>
If you inlude that using HTTP, it outputs "Hello world!"

Seems like a strange thing to do, outputting PHP code on a Web page, but 
it's not without conceivable usefulness.

[PHP] sorting multi-dimensional arrays

[Katie Dewees]

Hi All,

I've read the manual several times on sorting multi-dimensional arrays, but
I can't seem to wrap my mind around what I need to do to accomplish my goal.

//this is what I'm doing: (stepping through a result set, and putting it
into a multi-dimensional array.

while ($row = mysql_fetch_array($result)) {
$docs[$counter][doc_id] = $row[doc_id];
$docs[$counter][doc_name] = $row[doc_name];
$docs[$counter][clinic_id] = $row[clinic_id];
$docs[$counter][clinic_name] = $row[clinic_name];
$counter++;
} //end while

//now, I want that array sorted by the clinic_name, and then doc_name.

Can someone who has more currently active brain cells than me figure out
what the array_multisort function call should look like?

Thanks in advance for any help proffered! It is greatly appreciated!

Ah, I see. I think you could use str_replace (untested):

$a = 'order.php?order_id=';
$b = 'order_';
$c = '';

$new = str_replace($a, $b, $c).'.html';

You need to either put session_start() prior to any output (my preference)
or use output buffering by putting ob_start() prior to any output.

Hope that helps.

Re: [PHP] LOAD_FILE and PHP

[Jough P]

I've tried a couple different paths and double checked them.  
Permissions are 755.  Like I said that exact same SQL statement inserts 
the correct record from the mysql command line.

mysql> INSERT INTO photo VALUES('', 
LOAD_FILE("/Library/WebServer/Documents/var/tmp/default_smiley.png"));

does what I want it to do.

You're inserting two columns in your query, which one is "photo"? I

your error message at least). The file must be world readable in order 
for MySQL to read it and insert it into the table. I assume you've

[PHP] SOLVED => is ' or " different in MS-Word then ascII?

[Roger Spears]

Here is a real code solution instead of my original posted client 
solution

My original problem involved text submitted via the good old fashion 
 in a web form.  If a visitor created their text in MS-Word 
and then cut and paste their text over to the web form and submitted, 
any place within their text that they used ' or " would be turned into 
little white boxes.

After spending a day researching this problem, I realized I could just 
inform the visitors to turn off Smart Quotes in their word processor 
application.

Overcome with frustration and exhaustion, I posted this to the list as 
SOLVED and provided my client solution.  As many of you pointed out 
(thank you), it's not a valid solution for a large user base.  And as 
some pointed out (thank you), it's not a solution by any means...

Tom Rogers explained the problem and provided a code solution:
The problem is that Microsoft uses a non standard Latin-1 code for their 
"smart" quotes and a lot of programs don't know what to do with them as 
a few are actually control codes in other languages.


function clean_ms_word($text){
$crap = array( 
chr(0x82),chr(0x83),chr(0x84),chr(0x85),chr(0x86),chr(0x87),chr(0x88),chr(0x89), 

chr(0x8a),chr(0x8b),chr(0x8c),chr(0x91),chr(0x92),chr(0x93),chr(0x94),chr(0x95), 

chr(0x96),chr(0x97),chr(0x98),chr(0x99),chr(0x9a),chr(0x9b),chr(0x9c),chr(0x9f)
);
$clean = array( 
'‚','ƒ','„','&ldots;','†','‡','','‰', 

'Š','‹','Œ','‘','’','“','”','•', 

'–','—','˜','™','š','›','œ','Ÿ'
);
$content = str_replace($crap,$clean,$text);
return $content;
}
$string = chr(0x93).'Test'.chr(0x94);

echo clean_ms_word($string).'';

Thanks Tom!  Works like a charm!!  Also, thanks to everyone who offered 
tips, suggestions, and solutions...

Re: [PHP] dynamic array creation from form elements

Hi Rich,

$iListItems is set when a user chooses how many list elements they 
require (this is for the example pages I was asking about) and is 
always greater than 0 (we don't get this far in the script if it's 
not!).

Anyway, it was my silly fault, I had changed the name of my form 
elements whilst trying to fix it but hadn't gone back to the very 
begining in my browser so my loop was looking for the wrong post names! 
Doh!

Thanks,

I can't see the whole script, so this is just guess work - but your
loop is checking to see if $i (1) is less than $iListItems, but as far
as I can see this isn't defined anywhere in your code, so the loop
will never actually go through because it's saying 1 <= 0.
Where is $iListItems set and to what value?

Your loop will work, but it's not obvious it's getting the chance to.

Also you don't need to array_push it, you could just do:

$aListItems[] = $tempItem;

[PHP] Re: dynamic array creation from form elements

[Ben Ramsey]

Try using $_POST["listItem$i"] instead of $_POST["listItem" . $i]
or do something like this:
$post_var_name = 'listItem' . $i;

this do $_POST[$post_var_name];

I don't think you can do any evaluation within the brackets.  Thus, you 
couldn't use the concatenating dot.

Re: [PHP] Combining results - is there better way?

[John W. Holmes]

Miles Thompson wrote:
This code works, but are there alternate, more efficient ways of doing 
it. A count of subscribers, by classification, has to be provided, where 
the classification definitions are in one table (class) with this 
structure:

   nClassKey - unique, numeric, autoincrement
   Classification - text ,name of the classification
   ClassDesc - text, description of the classification
and a nClassKey value is stored in each subscriber record.

As the version of MySQL used by my ISP lacks UNION capability, I'm 
fetching the necessary data with two SELECTS. The first retrieves 
nClassKey and Classification from the class table, and the results are 
put in an array, $arClass, where the $key is nClassKey and $value is 
Classification. Pretty straightforward, resulting in [1]=>Development, 
[2]=>Retailing ... [13]=>Agriculture.

For the count of classifications I used the following SELECT:

   select nClassKey, count(nClassKey) as classcount from subscriber 
group by nClassKey

and stick it in the array $arCount with this code:

   while ($myrow = mysql_fetch_array($result)) {
$arCount[$myrow["nClassKey"]] = $myrow["classcount"];
   }   

All of this works. Note that $arCount can be a sparse array; there may 
be instances of nClassKey missing from the subscriber table simply 
because no one happens to fall in the "aerospace" category, for example.

To generate a listing for display, I am using the following code to 
traverse the $arClass array, searching in the $arCount for a matching 
key, leaving out all the HTML stuff:

   foreach($arClass as $key => $value){
  print( $value .  ":  ");
  if (array_key_exists($key, $arCount)){
 print( $arCount[$key] );
  } else {
print( 0 );
  }
   } // foreach
My question is if there is a faster, cleaner way to do this? I did try 
array_search, but as it looks for any matching value anywhere in the 
target array the results it returned were not reliable.
If I'm understanding you correctly, I think this'll work:

SELECT c.nClassKey, c.Classification, COUNT(s.nClassKey) FROM 
classifications c LEFT JOIN subscribers s ON c.nClassKey = s.nClassKey 
GROUP BY c.nClassKey

He means:

You have started a new thread by taking an existing posting and replying to
it while you changed the subject.

That is bad, because it breaks threading. Whenever you reply to a message,
your mail client generates a "References:" header that tells all recipients
which posting(s) your posting refers to. A mail client uses this information
to build a threaded view ("tree view") of the postings.

With your posting style you successfully torpedoed this useful feature; your
posting shows up within an existing thread it has nothing to do with.

Always do a fresh post when you want to start a new thread. To achieve this,
click on "New message" instead of "Reply" within your mail client, and enter
the list address as the recipient. You can save the list address in your
address book for convenience.

[PHP] dynamic array creation from form elements

[Jon Bennett]

Hi,

I've got a dynamically generated form and once it's submitted I need to 
_push the data from my form elements into an array so I can ad them to 
the db. My form elements are created like so:



$i = 1;

while ($i <= $iListItems){

?>


List Item :




++$i;
?>

And after the form is submitted I assumed I could do this...

$aListItems = array();

$i = 1;

while ($i <= $iListItems) {

$tempItem = $_POST["listItem" . $i];
array_push($aListItems, $tempItem);
++$i;
}
print_r ($aListItems);

but nothing appears to be added to the db, how can I access the $_POST 
vars within a loop ??

Thanks,

Jon

The only thing I can think of is that if you're using GET as your form 
method and end up with something like:

www.domain.com/file.php?v=/VAR

then maybe for some odd reason you're web server is actually looking for

a path of "file.php?v=" and "VAR" instead of realizing the "/VAR" is in 
a query string. That shouldn't be happening, though.

There could be something you're not seeing and assuming it's correct.

typing your code into the email we aren't getting the full story.

I guess you could write a PHP script that'll run continuously and

probably use less resources) if you just used Cron/Task Scheduler.


Awesome feedback guys. And quick too. No I am not opposed to using

Apart from the above points, looks ok for what you're trying to do.  Keep

[PHP] LOAD_FILE and PHP

[Jough P]

Greetings all, I can't get LOAD_FILE to work in an INSERT statement 
from PHP.  The generated sql works when you're in mysql but won't work 
from PHP.

BSDB is my database object.
sql_query basically just does a mysql_query and some error outputting 
stuff.  There error is:
Column 'photo' cannot be null

My SQL statement is:
INSERT INTO photo VALUES('', 
LOAD_FILE("/Library/WebServer/Documents/var/tmp/default_smiley.png"))

The first column is an auto-increment id, the second column is the 
photo.

Here's a code snippet:

   $uploaddir = '/Library/WebServer/Documents/var/tmp/';
   $uploadfile = $uploaddir . $_FILES['userfile']['name'];
   if ($_FILES['userfile']['type'] == "image/jpeg" ||
   $_FILES['userfile']['type'] == "image/png" ||
   $_FILES['userfile']['type'] == "image/gif" )
   {
  if (move_uploaded_file($_FILES['userfile']['tmp_name'], 
$uploadfile))
  {
 print "File is valid, and was successfully uploaded. ";
 print "Here's some more debugging info:\n";
 print "";
 print_r($_FILES);
 print "";
 echo "";
 $bsdb = new BSDB();
 $sql = "INSERT INTO photo VALUES('', 
LOAD_FILE(\"$uploadfile\"))";
 echo "$sql\n";
 chmod($uploadfile,0755);
 $result = $bsdb->sql_query($sql);
  }
  else
  {
 print "Possible file upload attack! Here's some debugging 
info:\n";
 print "";
 print_r($_FILES);
 print "";
  }
   }

Thanks for your help!!

Seems like a fundamental flaw in your program. If the user enteres 
01/02/03, what date is that? 2003? January? February? 1st or 2nd?
February. 1st. It's assumed in his environment that the format is 
dd/mm/yy, just like it's probably assumed in your environment that it's 
mm/dd/yy (I presume that based on your time zone). If you're developing 
for an intranet for instance, then you can work with such assumptions.

What I find upsetting in Tom's attitude is his generosity in harsh 
words: "a really fundamentally bad thing about PHP" would be not being 
able to cope with this problem at all, but let's be serious, writing a 
short function (as previously exemplified for free via e-mail by

Hello

Not sure if you thought of it or if it even applies to you but when you

PEAR::DB::getOnce("SELECT LAST_INSERT_ID()"); to retrieve the id do 
consider concurrent access to the database when using it for inserting 
stuff. Been there and its a hassle to resolve this little huge bug ; )
Consider the following situation:

Two users ( A and B) make simultaniouse access to your server. 
A queries the Database for an id
B queries the Database for an id
A writes stuff into the database using the retrieved id.
Now A and B both have the same id and if B wants to insert something into 
the db using id it will fail if id has to be unique (like in a primary 
key, foreign key, etc...)
B has to querie the database for the correct id again. 

So make sure you read lock the table for the query and the insert or make 
sure you never use the retrieved id for inserting stuff. 
You are very confused. User A and User B are on different connections 
and LAST_INSERT_ID() is connection specific _and_ you only use it 
_after_ you make an INSERT. It will return the last auto_increment 
generated number on a _per connection_ basis.

So User A INSERTS, User B INSERTS, then they each call LAST_INSERT_ID(), 
they'll get their own number from their own INSERT. You then use the 
number in subsequent INSERTs to maintain relationships.

If you read the strtotime() manual page, there is a link to this page:

You should be able to do everything in your query or use TO_UNIXTIME().
