i have a question about how to use sql database with php instead of using my
sql database
when i use my sql database the php code to connect to the my sql database is
=
$conn = mysql_connect($hostname, $user, $password);
if(!$conn)
{
echo "Unable to connect to Database";
}
else
{
mysql_select_db($database, $conn);
$query = mysql_query($selectquery);
mysql_close($conn);
}
if i have to connect to a sql databse instead of my sql database as some
companies use sql database, how can i change the php code to connect, run a
query and close connection to the sql database.
apart from changing the code to connect to sql database is there something
else i need to do.
please advice.
thanks

You should print the results that you are looking for!
Are you looking for something like this?
Array
(
[5] => Array
(
[1] => Array
(
[0] => some text
)
)
)
how is the $node string being created?
--- End Message ---
--- Begin Message ---
No offense, but I thought it's obvious what I want to print.
print_r() shows null, and it should print what you just wrote = array field.
It works when first defining with eval():
eval('$tpl'.$node.'=array();');
I guess that's the only way.
Anyway, I appreciate your quick reply,
Martin

Nope, you have to use the eval() everytime for read/write.

It's buggy... you need to test for an blank string to properly handle
the append to array case when the index is blank [].
<?php
$node = '[5][1][]';
$text = 'some text';
preg_match_all(
'|\[([^\]\[]*)\]|', $node, $matches, PREG_PATTERN_ORDER );
$recursive = $matches[1];
$recursive = array_reverse($recursive);
foreach( $recursive AS $index )
{
$out = array();
if( trim( $index ) === '' )
{
$out[] = $text;
}
else
{
$out[$index] = $text;
}
$text = $out;
}
print_r( $out );
?>
I also removed the (int) cast since integer keys will be cast
automatically by PHP and then it will have support for text keys also.
Cheers,
Rob.

I probably shouldn't trim... since we're not supporting quotes in any
way, it might be desirable to have a key that is one or more spaces...
for whatever reason :)
Personally, I have a similar implementation I use all the time, but I
use forward slashes to separate keys.

Hi there,
While this question can spur some neat solutions, it raises a red flag
in that if you need to do this, you probably need to rethink things a
bit.
In cases like this it is easier for people to help if you describe the
actual problem you are trying to solve, not how you think it needs to
be solved. It could be that you don't really need weird (but
beautiful, like Jim's idea) solutions. If you explain why you believe
that you need to do this in the first place, maybe someone can suggest
something else which doesn't require a weird solution (however
beautiful).

Forgive me if I misunderstand, but it seems like you are willing to
trade off an hour at the beginning of the project at the expense of
perhaps many hours of pain later on. Has this thread not already taken
more than an hour?
I find that often if I have a weird question, just taking the time to
formulate and write a good descriptive post to explain the problem
helps me understand why I'm going at it the wrong way to start with.
I remember years ago being faced with the same problem you now have.
It turned out that the most elegant solution was to change the design
so that I didn't need to solve the problem at all.

I agree with Torben.
Quite often when I formulate a question for this
group, the answer appears before I send the
question. One needs to fully understand the
problem themselves and preparing the right
question helps in finding a solution.
Of course, you can do like so many others do and
just don't worry about it -- expose your
ignorance to the group and hope for some magical
code. Despite my own advice, I've done that
several times. That works too, but has it's
downside.

Off the top of my head, I don't think this is possible. A quick Google
yields nothing either. I'm assuming it has to be a PSD for the layers?

Sure. I woudd like to read PSd files with multiple layes, and of course when
I write to it,
I should keep it's layers state also.
Is there any point to resource in some where please?
please help me. I need your help.

You want me to point you in the direction of a resource, even though
I've said I couldn't find one...?
The closest I can find is a class which will read a PSD in, although I'm
betting it'll only be a very, very old PSD.
It might be possible to do what you need by using the Gimp, but I'm just
not sure how much is possible with it over the command line.

What I know is that you can control GIMP over the command line = you can
use PHP to do this.
Though I guess GIMP doesn't support PSD files, I had to express myself
anyways.

The Gimp does support PSD files, but it has real trouble with the layer
effects that CS introduced. Also, the Gimp cannot natively handle CMYK
images.

Hi,
I would like to execute a jar file using exec('java -jar JARNAME <option>'),
but so far, my web application didn't gave me any hint that it did anything
(I tried to echo the result of the function, but nothing), and in fact I
don't think anything was done.
The jar file is in the same folder as the php scripts, so I don't know what
I did wrong.
Best Regards,
Bastien
