* Thus wrote Bob Lockie ([EMAIL PROTECTED]):
I'm having a very hard time testing array_search.
$j = array_search( $i, $errList );
echo "j=" . $j;
if (($j != false) && ($j >= 0)) {
<snip>
mixed array_search ( mixed needle, array haystack [, bool strict])
Searches haystack for needle and returns the key if it is found in
the array, FALSE otherwise.
</snip>
When ever you see that a function that returns mixed with a possible
FALSE Boolean value. You must always test your result as follows:
if ($j !== FALSE) {
// found an item
} else {
// no item found
}
Ok, I supected it was a boolean thing. :-(

Is it possible to specify the target frame in a "Header" call?
I have a form that submits in one frame and I want it to redirect to
another frame in some cases.
--- End Message ---
--- Begin Message ---
You could use javascript to determine whether or not to send it to the frame
and if so, the target attribute in the form tag can be used to direct the
form values to the frame for processing, if you're intending for the other
frame to process the form data.
If you're intending that the frame that submitted the form to process it and
then manipulate another frame, you could load javascript values based on
whatever results you had from processing the form and then use javascript to
manipulate the other frames location or values.
Geeze, that even confused me just reading it. Hope it makes sense.

I'm fairly sure there's a tutorial at PHPBuilder.com or Zend.com. Or
you can check the PEAR modules for code (I know there are database to
Excel classes).
If all else fails, Google's always helpful.

There is a mysql utility that does this:
mysqldump -p mypassword -T mytargetdirectory
mydatabasename [mytablenames]
(The "-T" tells it to dump the data in tab-limited
format. Otherwise it generates a series of insert
statements.)
See:
http://dev.mysql.com/doc/mysql/en/mysqldump.html
One pointer: the mysql daemon does the writing so the
mysql user must have write permission on the target
directory.
Hope this helps.

Are you talking about regular old (browser-based)
Javascript? Javascript and (server-based) PHP are like
apples and oranges. You can't really get the same
error from each because they are doing completely
different things in completely different places.

PHP functions are executed by the server. The browser
(Netscape and IE) have nothing to do with them.
gethostbyaddr is a simple reverse-DNS lookup (of the
REMOTE_ADDR ip address) requested by your server to
its nameserver. This never goes near the user's IE or
Netscape browser.
The IP address used is the one your webserver is using
in its HTTP (TCP) connection with the browser (or its
agent -- a firewall or proxy, for example).
If there is no DNS entry for the ip address, there
should be no hostname returned because by definition
there is no host name to be returned.

For debugging purposes, I would add more verbose echos:
particularly for IP address and full host name
returned ($hn).
How are you deducing that you are getting different
results based on the user's browser?
Are there firewalls or web proxies involved? This could
account for getting conflicting IP addresses for the
same user reported by the browser (via Javascript) and
server.

Hi,
I also have an installation guide on PHP4/5, Apache2, Windows XP but it
is written in Vietnamese (
http://www.opensourcevn.org/javavietnam/php/caiphp.htm ). Could you give
me some details on your installation process ?

I have an abstract class with quite a few 'children'. Essentially I want
to be able to interchange calls between children (Take a script, written
with ClassA and redefine the variable as ClassB etc.)
Though there is a large subset of methods all of these children declare,
there are a few which only *some* declare. What I think I'm looking for
is a variation on an abstract method that, if not defined in a child,
will do nothing. Using an abstract method forces me to declare the
method in the child with an empty body.
Are you understanding me?
Any thoughts on the matter would be appreciated.
Thanks,
Chris

AFAIK, there is no support for this explicitly in PHP5. You would have
to implement something yourself, like putting a die() or exit in the
abstract method in the parent class.
If you just want an empty funciton anyway, why don't you just put an
empty function in the parent? I don't see why you would need PHP to yell
at you when you don't want to do antyhing with it anyway.

Hi,
Yes, namespaces has been removed from CVS for PHP5 but Object Model for
PHP5, based on Java, has been improved. I would like to say: plz forget
PHP4 and rush into PHP5.

It's not persistent like ColdFusion.
It doesn't have namespaces.
The object model in PHP 4 is poor.
I'm sure others can pitch in here. :-)

I'm working on a photo site and most of it is working. The intent is to
store original high-resolution photos that will only be accessed when
purchased, and then a variety of thumbnails that will be accessed when
viewing. Because they're high-resolution, I need maximal image
compression but I can't sacrifice image quality. With hundreds (or
more) of many megapixel images, space requirements quickly soar.
I am currently using PNG, but that's not all that great for lossless
photo compression. JPEG 2000 is significantly better in terms of file
size, but I haven't ever used that with PHP (and it seems I'll have to
use it via ImageMagick or something). Are there any other (free)
formats for high image compression out there that I can use (maybe even
just via the shell) with PHP?

Maybe what you want is strlen()?

I am beginning a project that will involve moving data
from an mssql table to xml files.
In addition to fixing non-xml compliant html in the
text fields and outputting the data to a new xml
format, I need to find certain chunks of text marked
by standard html comments at the start and end,
comment out everything between the comments, and
insert the found text into its own xml element (which
will in some cases be inline).
I have played with code using substr/str_pos, running
html tidy with exec() and it works. But searching the
archives, it seems like the new html tidy tags in php5
will be more useful. In most cases the target text is
in a one row, one cell table.
Any advice on how to attack this would be appreciated.
I can handle the coding, I just have a feeling I am
approaching this from the hard way.
