You need to understand how PHP treats integers. It can never start an
integer with a zero unless it's an octal or a hexadecimal number. And
PHP will not hesitate to parse a string as an integer. For example, even
if you had $a = "01" (clearly "01" is a string), and then did echo $a+1,
you would still get 2 since "01" will evaluate to the integer 1.
Read more on integers here: http://www.php.net/types.integer
Now, to answer your question, just use the str_pad() function:
http://www.php.net/str_pad
Looks like this:
$a = 1;
echo str_pad($a+1, 2, "0", STR_PAD_LEFT);
This will output "02" as desired.

use printf( "%02d", $a + 1 )
or something like that. Should work.

How is it not working? What does var_dump($attributes) show?
> I list my $HTTP_SESSION_VARS, there are none.
Is this related to the above? $HTTP_SESSION_VARS would normally be empty
unless you start a session and register some session variables.

1) Usually there is little point putting the request variables
($HTTP_POST_VARS, $HTTP_GET_VARS, $_GET, $_POST) into the local namespace.
Just use them directly as you have here:
> switch ($_POST['action']){
> case "Add Record":
> ...do stuff...
2) If you really must do (1) then instead of:
extract($attributes, EXTR_PREFIX_SAME, "this");
you should probably use this:
extract($attributes, EXTR_PREFIX_ALL, "this");
that way you'll know that variables prefixed with 'this' came from
$HTTP_POST_VARS, $HTTP_GET_VARS. BTW why are you processing $HTTP_GET_VARS?
You're using "POST" for your form.
3) To save confusion use only the new "superglobals" ($_POST, $_GET etc) OR
only the old, deprecated request variables ($HTTP_POST_VARS, $HTTP_GET_VARS).
Do not mix the two in the same code. See manual for details.

Hey everyone, I'm having issues with a couple of forms that exist on one
page. Basically what I'm trying to do is the following:
Select a client from a dropdown select box(submit inner form). Based on
that, another select menu appears that retrieves a list of projects based on
the client selected. Then you choose a file and upload it(submit the outer
form) which uploads the file and adds the file entry under the client
project table selected in the 2nd dropdown.
The problem is that the outer form works fine, but the inner form that
dynamically retrieves the client project list doesn't refresh the page or
post so the project list never shows up. I've listed some code below.
Forms can't be nested. From your description it looks like the best way
is to use 2 forms, each on a separate page.
Another way is to use a form that posts to itself, but the action is not
taken until a project is selected and a file is uploaded.

Hi there.. I have a text file where I need to remove JUST the first

Start with fopen() - http://us2.php.net/manual/en/function.fopen.php
Then use fread() - http://us2.php.net/manual/en/function.fread.php
There's many user-contributed comments that should be of use. The docs are
also quite helpful.

Just want to add to this with a little more info....
my text file is a list of email addresses with a "%" separating them.
For example:
[EMAIL PROTECTED]@[EMAIL PROTECTED]
Now sometimes I end up with a "%" at the beginning. For example:
[EMAIL PROTECTED]@[EMAIL PROTECTED]
Or:
[EMAIL PROTECTED]@[EMAIL PROTECTED]
Now that causes me issues else where in the script. So what I need to
do is check if the "%" character exists at the beginning of the file
and remove any if the "%" is there.
ideas?

Hi All, im new to classes in PHP. Im trying to create
several instances of a very basic class but i want
each name to be based on number values in an array and
im not sure if it is allowed and if so how to do it. I
assume that im not allow to have a var starting with a
number so what i am trying to do is add the word case
to the front of the class instance name so i would
have $case100,$case101 etc. Im am using PHP 5.02.
Heres my code
<?php
class Test
{
//members
var $caseid,$fee;
function Test($caseid){
$this->caseid=$caseid;
}
function addmember($membername,$value){
$this->$membername=$value;
}
}
$names=array("100","101","102","104");
$numnames=count($names);
for($i=0;$i<$numnames;$i++){
*** below is the syntax im missing ***
$case.$names[$i] = new Test($names[$i]);
}
var_dump($case100);
?>
Thanks for any help in advance!
Cheers
Bob Pilford

$pref = "case";
for($i=0;$i<$numnames;$i++){
${$pref.$names[$i]} = new Test($name[$i]);
}

Hi
I use fpdf to generate pdf on the fly. It should display pdf in the browser
and it's ok withou mod_gzip.
Actually the problem is mod_gzip.
It seems IE doesn't work very well with this combination. No problems with
Firefox.
Anyone had this problem too?

In the phpinfo() output, the MySQL client API version is shown as 3.23.49.
Shouldn't this be upgraded to 4.1 (generally available/stable)?
