The cast isn't necessary, PHP happily transforms it for him when he
applies the ++ operator.

;) You are sure about that right? Or else you wouldn't have posted this
to 1000's of people.
So what do you think this will output?
$a = "123\n";
$a++;
echo $a;
Try it.

I am absolutely sure of thus since I cut and pasted the original problem
code to a shell script to test. This was before I noticed the answer
mentioning the closing if block had already been posted.

Undoubtedly the above will work as we both know, the output will be
"123"; however, if you look at the original code in question, there is
no "\n" tailing the output written to the counter file and thus the
increment works fine (unless of course when he created the file to begin
he had a newline - something I did not do in my test :)

Rob.

which is exactly what it looked like he did since he said that switching
to $counter+=1; fixed it for him which would force it to be an integer.

How did you create the file in the first place? Most editors will
automatically add a carriage return. Even if you had your code create it,
if afterwards you ever edited and saved the file with an editor, you would
have gotten one in there.
The proof of this is that your code didn't work. If the file really only
had a number in it, then $counter++ would have worked.

Hi guys,
This might just be off the topic, but here it goes anyway:
How can one multi select check boxes and pass them through in php,
without getting mixed up with variables (email multi select style).
Thomas
--- End Message ---
--- Begin Message ---
Hi Thomas.
You need to name each checkbox a different name.
alternatively, you can name them with array naming convention.
i.e.
<input type=checkbox name='array1[value1]' value='Y'> 1-1
<input type=checkbox name='array1[value2]' value='Y'> 1-2
<input type=checkbox name='array2[value1]' value='Y'> 2-1
<input type=checkbox name='array2[value2]' value='Y'> 2-2
Checking off 1-1 and 2-2 would create the following variables (assuming
register_globals is on) in the target php script for the form:
$array1=array("value1"=>"Y","value2"=>"");
$array2=array("value1"=>"","value2"=>"Y");
Hope this helps
Matt

Hi,
that sounds really impressive. I'm using Redhat 9 with
the stuff from their Edition, that means Apache 2 and
php together. Never had any issues (so far.....keep my
fingers crossed). The server is not under heavy load,
but it is indeed a "production server". I know it is
not recommended, but for this use (mysql & apache &
php on that server in a company intranet, used for
keeping a picture library & administration issues) is
it necessary to change it? Please advise. To my
defence I have to say that the data on the server is
backed up regularly, though not the OS itself, since
if something ever happens it is less hassle to do a
complete new install & get the database back on. Any
hints?
Thanks

We (at hyperreal.info) used PHP+Apache 2 for
a while, but it created so many problems (stability,
non working SSL, others) that we have returned to
the 1.3.x version...and now everything works like
it should :8].

OK, so Apache 2 is out. Is there any reason not to go with RH 9.0? Any known problems?

It should be fine. Linux is pretty much Linux. The biggest differences
between distros and distro versions are at the GUI level and in the set of
applications they provide. If you are going to use it as a web server and
you install known good versions of Apache and PHP, then you have taken RH9
out of the loop for your critical components and it should be fine.

Hi,
I am making a small PHP script for managing a simple mailing list. The
PHP script is added in the bottom of this message.
This PHP script works great on IIS 5.1 with PHP 4.3.0, witch I have
installed locally on my system to test my scripts. But when I transfer
the script over to my host server (With IIS and PHP 4.2.1), I get an
error message when I'm trying to use it. The error message is like this:
Warning: Failed to Receive in

Is there any compatibility problems between 4.2.1 and 4.3.0 for the
codes I have used in my script?

Håkon Strandenes
Here is the script (It get its inputs from this form:

Hey folks,
Iam trying to call the ssh program and have it connect to a remote host and
authenticate, however I havent been able to do it. I used this script but all

command returned 255
At the error log i specified i get:
Permission denied, please try again.
Permission denied, please try again.
Permission denied (publickey,password,keyboard-interactive).
Note that it doesnt even ask for a password.. just says denied immediately.

Look in php,ini (and crank up error reporting to full) and/or read the
relevant chapter in the manual.

You could use Javascript, i.e. when cursor leaves the last form element
use the relevant function (sorry can't remember which) to submit the

'com_features.com_features.id = 2'
ie
X Window
pool

The query I am using now is:

features.fName AS fName,
com_features.feature_id AS feature_id,
com_features.com_rec_id AS com_rec_id

What I get in the return is:
X Window
pool
fence
drive
Window

X fence

Window
pool
fence
X drive

Hello,
First let me say that I am not sure if this is PHP problem or Oracle.
I have a class that contains API for using postgresql, mysql, or oracle
database so switching database should be "in theory" just changing an
argument for me.
To make this sort, let just say that the return of a SELECT statement is
always in associative array, using either :
"pg_fetch_assoc" for pgsql
"mysql_fetch_assoc" for mysql
"ocifetchinto" with OCI_ASSOC flag for Oracle 9
Now, pg_fetch_assoc and mysql_fetch_assoc return the associate array with the
key in lower case. But ocifetchinto returns the key in UPPER case. So this
discrepancy makes my code not as portable as I would like it.
Furthermore, the example here:
http://us2.php.net/manual/en/function.ocifetchinto.php
doesn't even work, because it uses lower case as the associative array key.
Why is this the case? Is this PHP problem or Oracle config problem? Either
way, can anyone suggest a solutions? Of course I can do all kind of array
manipulation in my API to make the key lower case, but that wouldn't be very
elegant and efficient
Thanks in advance for any help.

No, that is just the way Oracle returns column names. It is not possible
to provide a portable solution to return row in associative arrays
because not only the column names case may be mapped, removed the table
names or even have the column names truncated.
That is the reason why Metabase never provided a function to return rows
as associative arrays, as Metabase is focused on real database
application portability.
