^^ A ^^ ^ B ^
A) PHP variable names are case-sensitive, $_SESSION != $_Session
B) You probably want to replace the () with [].
{
$_SESSION[qs] = $_SERVER['QUERY_STRING'];
session_register(qs);
You cannot (should not) mix the use of $_SESSION with session_register().
RTFM.
If you redirect without closing the session then any changes to the session
variables will lost. So you need a session_write_close().

Use:
isset($_SESSION['qs'])
or
!empty($_SESSION['qs'])
rather than
$_Session(qs) !=
and similarly for $_SERVER['QUERY_STRING'].

A general rule: it is pointless (in most cases) to assign values from the
superglobals (such as $_SESSION) to other variables. Just work with them
directly. Trivial example:
Instead of:
$firstname = $_SESSION['firstname'];
$lastname = $_SESSION['lastname'];
echo Hello $firstname $lastname;
Just do:
echo Hello {$_SESSION['firstname']} {$_SESSION['lastname']};

Now that we have nice c-like script languages like PHP, Python and Javascript who still wants to study the mess that Perl is? snip The O'Reilly Perl books are considered to be like Perl Bibles by most Perl programmers (myself included). I have 'Perl in a Nutshell' as part of the Perl CD-Bookshelf (which has about 5 more books on CD). And I have the Perl 5 Pocket Reference in Dutch, and yes the books are of the to-be-expected O'Reilly quality, as far as I have read them, but why did Perl ever become a standard and who still needs it? It probably became a standard because the designers of compiled languages recognized too late that because of the increased speed and memory of computers the interpreted languages became a viable option (again). And Perl was probably indeed a lot more powerful than the commands built into the shells, but already the designers of the c-shell realized that some more c-like structure wouldn't hurt the programming language of a shell. In Perl however everything was solved as ad-hoc as possible. As soon as a new 'problem' occured, Larry Wall found another combination of weird characters to denote it and so he created exception upon exception. It's not strange that programmers need stacks of 'bibles' to program in Perl, whereas you only need to read through the introduction of the PHP manual once to understand the language. After that, most time is being spend on understanding the principle of interactive HTTP-based programming and on getting to understand all the library functions (like in many languages). I may be biased, but I did some homework (as I look at the 8 non-O'Reilly Perl books on my shelf that have gathered dust for over a year now while the Camel book sits open on my desk (it's usual place)). When you look beyond the web (which Perl was never designed for), Perl was never really designed. Good designs are as simple as possible and orthogonal. Perl is one of, if not the most powerful scripting language out there. How do you define powerful? Being able to denote with only a few weird characters a complete program? I can design a language in which you can write a program which consists of only a '.' and it will handle a database, build a robot for you that cleans out your refrigerator and picks up the phone. But how flexible will the programming language be? Is it possible to write a ',' instead of a '.' and will it be a perfect CAD-CAM program with which you can also access the IRC? Or is a good language such that it has no more elements and concepts than needed whereby all elements are orthogonal and are all combinable to provide real expression power. PHP is the greatest thing to hit the web since the graphical browser, but beyond that, it can't compete with Perl. It's in the mean time perfectly possible to write normal command line interface (CLI) PHP scripts. I'm thinking about replacing a lot of the written-in-C compiler-like applications with which I compile my 30 Mbyte WWW site about chips with PHP-written scripts. The string handling is much better than in C. In another thread someone asked if functions should output data directly to the standard output or only return it in string form. This is one of the problems with my c-written code: It usually outputs directly to some sort of output stream but it would be much more flexible if all functions returned strings, so the output could be redirected via filters etc. Python comes close, I like Python too. but Perl is just too big and global for Python to handle. But serious programmers never programmed in Perl. It was much more the language for system and network managers that had no formal programming education and quickly had to fix things. As with Forth it's very hard even to read back ones own script after a couple of days let alone the programs of others. I can easily read back C programs I wrote 10 years ago and immediately understand what they do. And JavaScript? Well, let me just say that JavaScript handles the Microsoft IE DOM better than Perl. I was talking about Javascript as a language. Of course it's power is very limited since it has to be safe enough so hosts can send it to the client's browser to be executed. The language itself is very nice though. By the way, I think there should be only one language and depending on the circumstances more or fewer of the constructs and standard functions in it would be allowed. There should ideally also be only one set of libraries.

[PHP] magic_quotes_gpc - 4.0.1 to 4.3.1
Hi List Is there a difference in the way PHP handles the magic_quotes_gpc between these versions? I had 4.0.1 running on my server for a little over a year and all went well, ie, data that contained quotes etc were discreetly handles by PHP and inserted into MySQL with no problems ( when you vies the data in the table with phpMyAdmin for instance, you would not see any slashes in the content. However, since I upgraded to 4.3.1 (and turned on magic_quotes_gpc), I notice that the same process now produces slashes in the db, meaning that I will now need to edit my code and add stripslashes() when I need to display them. [STOP RIGHT HERE] - I KNOW that it is best to use addslashes() and stripslashes() BUT, I inherited the code, and it is really going to be an enormous task to go through the code for the entire app. So naturally I'm looking for a quick fix in the form of another magic function, and in the absence of such a function, I'd like to know what the differences are, maybe I can then look at a class or a function to handle all for me???

Ok, it's a rather bad way to do it, but it works for me... Even the php crew had to rewrite functions because it displayed data instead of returning. Case in point: print_r() recently had a extra argument added to specify whether the output was printed or returned. I agree with your point, but the adding of the second argument was more of a convenience thing than an admission that printing when calling a print statement was bad behaviour. :) Besides, it's more consistent since the introduction of var_export() with its similar abilities. As to your actual point (no more hair splitting): I agree. If the function has something to say, it's better to store that somehow and then use it when you need it. You get to determine when (and if) it gets output, and how. As someone else noted, you will sometimes find it necessary to break this rule (quick debugging statements, or functions whose purpose is to actually output something), but in general I wouldn't expect to see any benefit to having your functions doing their own output--beyond the initial convenience. For one thing, it can make effective use of templates a bloody pain.

Re: [PHP] Re: Difference between $_POST[foo] and $_POST['foo']?
At 12:42 17-6-03, you wrote:
the first will generate a warning if warnings are enabled.
it could mean a constant or a string, if a constant with that name is not
available
php will use it as a string and show a warning.
the second is right as a string.
in addition to that.
In your example the array key is a string.
'foo' is a string.
(if $string_a='foo'; ) $string_a is a string
foo is not a string
but after define('foo','stringvalue');, foo is a CONSTANT with a string
value. see http://www.php.net/define
If you type $_POST[foo] in a piece of code, PHP recognizes that foo is not
a normal string such as 'foo', and not a variable as it does not have a $.
So then PHP checks its definition-list to see if 'foo' is defined. If not,
PHP will issue a warning (if turned on) that says something like i assume
you mean 'foo') and uses the string 'foo' as key. This is extra work for
PHP and should be avoided, although you see it a lot.
There is one confusing exception: within double quotes strings, you may use
array keys without the quotes. For example like $_POST[foo];. If you can,
I recommend using 'For example like '.$_POST['foo'].
Last one: $_POST[foo] is ok too but now PHP will first check the string
foo for possible variables inside: (a little bit of ) extra work that is
not there with single quotes ($_POST['foo']).

Re: [PHP] Dynamic menu not passing value to PHP?
Got it sorted out now
$query_rsCat = SELECT * FROM inventory WHERE category='$sltCat' OR
item_name LIKE '%$txtSearch%';
This will select all the items if either $sltCat or $txtSearch is empty.
Janet
'%$txtSearch%' would always evaulate as '%%' in Mysql when the txtSearch
field is empty thus resulting in Mysql selecting everything in the database
making the the category='$sltCat' redundant...
I've rewritten it as:
if(empty($txtSearch)){
$query_rsCat= SELECT * FROM inventory WHERE category='$sltCat';
}
else {
$query_rsCat=SELECT * FROM inventory WHERE item_name LIKE '%$txtSearch%';
}
to circumvent this and it worked..
Thanks Janet for pointing this out...and thanks all for the help

Maybe you can make it a little bit clear for me?
You have not defined $i, so what did you expect to see here?
session_start();
$aantalpers=$_SESSION[aantalpers];
$test1 = $_SESSION['test1'][$i];
So is it going to be: $test1[$i ]= $_SESSION['test1'][$i]; ???
No. This is worse than before. You still have not defined what $i is -- it has no
value, it is unset, it is equivalent to NULL. Therefore, $_SESSION['test1'][$i] is
unlikely to return anything meaningful. At least before you were putting unknown
result into a known location ($test1) -- but now you're trying to assign it to
another non-meaningful place ($test1[$i], which is an unknown quantity because $i is
still undefined!).

[PHP] Form Elements - user adding dynamically
I'm constructing an HTML form (via PHP) in which I want the user to be able to add or delete elements as needed. For instance, in a page detailing user information, the user might have one phone or several. Rather than having a set number of slots for phone numbers I'd have one slot and have a button by which the user could add a slot. The user could also delete a number in a similar manner. The design goal is something like Apple's iTools web page construction tool. Beside each slot is a - and a + to delete that slot or to add another one just under the existing slot. I've got something worked out that is beginning to work, but I wondered if anyone on the list had faced a similar problem or knows of an example script that handles a problem like that.

Re: [PHP] Basic Help
You say to RTFM, are there any good resources for new users? I know PHP.net
has an extensive manual but a tutorial or a list of commonly used
features/functions and there uses would be better for me. I need to learn
about database connectivity in particular and unfortunately I must use
ACCESS as my back end.
Thanks in advance,

A) PHP variable names are case-sensitive, $_SESSION != $_Session

You cannot (should not) mix the use of $_SESSION with session_register().
RTFM.
If you redirect without closing the session then any changes to the
session

among other problems if there is no querystring value at all it gives me
an

Use:
isset($_SESSION['qs'])
or
!empty($_SESSION['qs'])
rather than
$_Session(qs) !=

RE: [PHP] functions, opinion...
Hi, My personal opinion, which shows in all my code writing is to never echo inside a function. always return the data whether it be string, array, or boolean... I've always left echoing up to the actual page showing the data. That way if you have two seperate pages that need to display the data differently, you can use the same function, and just format it as needed on the pages. This is kind of what I thought would be the majority of the responses. I've found that since the inception of web languages (ASP, PHP, etc) that I've abused functions a bit. I then got to thinking one day that maybe what I was doing was normal, but then I figured that it probably wasn't. At times it seems like it caused me to scramble all my logic. -Dan Joseph -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] functions, opinion...
Hi, Depends on the use of the function. (Output functions should produce output shouldn't they?!) Best option probably is to specifiy an argument that allows to choose wether to output or to return. If you return text you should return by reference to prevent unnecessary memory consumption. Recently, I have been doing more of returning than echoing from inside a function. I found it more useful I guess. Seems the general consensus is to simply keep the echoing from the functions most of the time, and in some minor cases, use it. To me, this makes sense. Thanks all for your opinions. -Dan Joseph -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Password generator
Hi people,
I have to make a password generator, but i have a little problem.
- It needs to generate password 8 characters long, and including 1 or 2
special characters(like #$%*@).
- Those special characters can never appear as the first or last
character in the string... anywhere between is fine.
I have a password generator script now that does the first thing... but
the special character can be in front or back of the string wich it
shouldnt.. i have been looking on the web for this but i havent found
the answer. Below is my scripts so far..
Any help is appreciated, thanks for your time,
Best regards,
Davy Obdam
?php
// A function to generate random alphanumeric passwords in PHP
// It expects to be passed a desired password length, but it
// none is passed the default is set to 8 (you can change this)
function generate_password($length = 8) {
// This variable contains the list of allowable characters
// for the password. Note that the number 0 and the letter
// 'O' have been removed to avoid confusion between the two.
// The same is true of 'I' and 1
$allowable_characters = abcdefghefghijklmnopqrstuvwxyz0123456789%#*;
// We see how many characters are in the allowable list
$ps_len = strlen($allowable_characters);
// Seed the random number generator with the microtime stamp
// (current UNIX timestamp, but in microseconds)
mt_srand((double)microtime()*100);
// Declare the password as a blank string.
$pass = ;
// Loop the number of times specified by $length
for($i = 0; $i $length; $i++) {
// Each iteration, pick a random character from the
// allowable string and append it to the password.
$pass .= $allowable_characters[mt_rand(0,$ps_len-1)];
}
// Retun the password we've selected
return $pass;
}
$password = generate_password();
echo $password;

Actually I didn't. The code that I gave would result in a string like: select * from db where apple = 'blah'; For your reference: \'' means print one single quote then end the current stream. Then the . $_POST['foo'] appends the value of foo to the stream, then . '\';'; prints one more single quote to end the quote's around the value, and adds a semicolon at the end of the string to tell MySQL the query has ended.

Go back and count the quotes again. The original post is correct as far as
quotes go. Yours is not, though, since you have three single quotes in a row
and have thrown in a double quote by itself.
Without color coding, this is all very hard to tell. That's why I prefer to
do it such as:
$sql = SELECT * FROM db WHERE apple = '{$_POST['foo']}' ;
or, like someone else said, the following is perfectly valid:
$sql = SELECT * FROM db WHERE apple = '$_POST[foo]' ;
There are way to many methods to do this, though, so just use the one that
makes the most sense to you. I've changed my mind about this a few times in
the past. :)

[PHP] Problems passing variables from Javascript to PHP
Hello =) I'm embedding an SQL query constructed in Javascript to an URL and opening it in PHP where I try to execute it. Problem is, the string arrives garbled, with all the apostrophes escaped. This must be Javascript's type of safe url encoding, but how would I go about decoding it in PHP? I thought about urldecode or rawurldecode, but Javascript doesn't seem to use RFC 1738 encoding (because of the escaped apostrophes). Then I thought about writing a Javascript function to encode the query string into RFC 1738 %-format, but then I couldn't use unicode characters in my query, right? What to do? I need to find a way so that the string can be encoded in Javascript and decoded in PHP and not get garbled.

Paul GnuPG Key http://sgi.rdscv.ro/~paulm/paulm.PGP Using a cron job is by far the best bet, if you are not allowed cron jobs on the webserver do you have access to another computer that you can run cron jobs on (you could call the PHP script using lynx from the other server). A work around is that you could have an include in each of your pages that checks the time and decides whether to do the tasks you were going to do in the cron job. This will only work if you have a busy site and if your cron job does not take long to execute though.

In addition to what others have said, you don't _have_ to set up the cron job (or any scheduled job) on the same computer as your scripts. If you have a Cable/DSL connection, you could set up a cron job on your own computer to connect to http://www.yourdomain.com/cron.php and run it when you need it. If you have windows, you can even do the same thing with Task Scheduler.

[PHP] PHP versioning and security information
Hi, I'm trying to figure out if the version of php that I am running is secure against all known exploits and I am finding that task very difficult. I haven't been able to find a security page on either http://www.php.net/ or http://www.zend.com/ My questions are: - is php 4.2.3 vulnerable to any known security issues? - what is the meaning of php's versioning scheme? I see from the changelogs that features are added throughout the 4.x branches. I am used to schemes where 4.2.x would be feature frozen with just bu and security fixes being applied. - is the 4.3.x branch the only one that is being maintained? I do not relish moving my servers from 4.2.3 to 4.3.? since I have encountered enough problems already with the move from 4.0.6 to 4.2.3. Most of the problems were from sloppy coding that should never have worked but hey it did work with 4.0.6 and does not work with 4.2.3. If the code were all mine I wouldn't be so concerned but I don't want to be telling clients every 6-12 months, that we're upgrading their php version and that things might break for them. Is there an official policy as to how long a branch is supported? PHP 4.2.0 is just over a year old, php 4.2.3 about 6 months old ...

Please be very, very careful. There's a big big hole there.
Problem is, the string arrives garbled, with all the apostrophes escaped.
Escaped how, exactly? With backslashes? Doubled apostrophes?
The obvious thing would be a
$query = str_replace('', ', $query);
But again, please reconsider what you're doing - it sounds like you're

Change your error reporting level
http://www.php.net/manual/en/function.error-reporting.php
(or set globally in php.ini)
or supress the error with @ (can't find a URL, but essentially place @ in
front of a statement to supress errors).
However... that's just supressing the warning, not fixing it. It's odd that
PHP would throw a warning if the file doesn't exist. What warning are you
getting, exactly? What happens if you have a script that just contains
?
if (file_exists('test.txt')) {
echo(one);
} else {
echo(two);
}
?
Hmm... could this be your bug? http://bugs.php.net/bug.php?id=15932 Maybe an
upgrade would fix it.

Re: [PHP] bcmod()
if I read it right it looks like it returns what is the remainder as per any

so fer instance you want to get the remainder when you divide 10 by 3 (which
we both know is 1)
$remainder = bcmod(10,3);
for example I think
