Is there a way to access a column in Mysql just by using a number?
Please refer to the MySQL-Documentation. A database doesn't have
any predefined structure, so you're responsible for doing this. Can you
explain why you need this feature?
Like if you had three columns called column1,
the columns/fields
are
defined is their numeric order.
Second, mysql_fetch_row() will accomplish what he needs.
Third, we answered this yesterday.

Can anyone explain me why the following code causes
the parse error ... unexpected * ... ?
class test
{
var $a = 2*10;
}
Of course I know why there's a parse error, but I don't
know the reason why PHP doesn't allow this multiplication,
although it allows a statement like e.g. var $a = 20.
Any reasons why there's no gmtime()-function in PHP? I'd like to hear your
thoughts.

Did you see gmdate()?

Yes, of course.
I can do time()-date(Z) to have gmtime
(or maybe) something better, but wouldn't it be better to
have gmtime() implemented anyways? Please tell me if I
missed something. Thank you.

this behaviour is not documented it's probably confusing to a lot of people,

Hi there,
I am pulling out an image out of a mysql blob field. The image is there, I
can see it in mysqlfront. So I pull it out of the db store it into a
variable and then do a:
header(Content-type: image/pjpeg);
echo $picture;
I do get a white screen and the browser is loading
Just be sure you call session_start() on any page you want to access
session variables.
I have to call this function on each page I use session variable or juste
once ?
The statement is pretty clear. You've to call it once on each page you want
to access session variables.

I have a script that switches.
switch($pid)
{
case 1:
break;
case 2:
break;
}
Now I'm doing a check in case 1 and if everything goes well, i want to
switch directly to case 2 while the script is runny.
How would i do that ???
Don't write break; in case 1.

I don't know what gmtime() is supposed to do. But is gmmktime() similar?
http://www.php.net/manual/en/function.gmmktime.php

Sorry, my first answer was incorrect. gmmktime() does not do what I want.
Do you have any other suggestion why we need/don't need gmtime()?

Maybe Apache and PHP have problems with the 2MHz-CPU. :-)
I can only guess what may be the problem:
1. You didn't write phpinfo.php correctly.
2. phpinfo.php is in the wrong directory.
I suggest this because if the apache-site comes up correctly and
phpinfo.php does not it _might_ be a

1. The url you have entered is invalid. Thats a good first check to

I would suggest that you try writing a script that keeps track of how
many tags have been opened (look for ), versus how many tags have
been closed ([^]*/) on a line-by-line basis. Using that number, you
should be able to indent the code properly.

Hi out there,

Usually entities start with and
