Actually, a minimal victory.
If it can be used, I'd go for the clarity of switch.

Hazardous is right. That's a terrible benchmark. Could have eliminated
hundreds of sources of skew by running the iterations at the command
line. It even does an echos *lol*.
I ran the following as two shell scripts, 10 times each and averaged the
times to get that switch is faster by 0.000000122 secs. Big whup, as I
said in a previous post, that's very likely due to the precomputation
being assigned in userland PHP versus the internal engine. As for which
one is best, that's just flamebait -- right up there with preferred
braces style, tabs or spaces to indent, top post versus bottom post
*teehee*, etc. Personally I prefer if/elseif/else for a moderate number
of conditions or if the conditional expressions are very complex. Switch
I generally use for a large set of constants. They both have readability
pros and cons.
Cheers,
Rob.

Sure, use ab (Apache Benchmark) which comes with your build of apache.
Simply create your file foo.php and give ab the command
ab http://www.example.com/foo.php -n 10000 -c 4
you may also use localhost as such
ab http://localhost/foo.php -n 10000 -c 4
If the concurrency is omitted a concurrency of 1 is assumed
This will tell ab the url, and to request it 10,000 times with a concurrency of 4.
Depending on your hardware ab will tick over and generate a report.
man ab will give you more info
Kind regards
Kevin

Hi all,
I am postilng pictures up on a website. So far I have a picture per

anyway that I can have one page with only the image updating? Can
this be done in PHP. If it can would someone explain it to me. The
only thing I k.now how to do well in PHP is mysql queries and data
validatlion.

No PHP can't do something like that.
Problem is that PHP can't delete the output Buffer.
I think, but i am not quite sure, that this can be done with AJAX.
Also some Java-Applets are able to do stuff like that.
It will still be tough since you have to tell your browser somehow that
he has to reload the image.
Not quite easy.

Check out http://gallery.menalto.com/ There is a way to watch a

http://www.akehrer.com/ffgallery/ is an Ajax and PHP photo gallery (it

Slowly I am getting the output I want.
Trying to use "dynamic" arrays, does creat the array I want, but getting
the info is sometimes surprising.
I notice a difference between arrays used locally in a function, and
arrays used as a 'var' in a class function (all in PHP 4 atm).
Code snippet:
echo "ROWS returned are: $max\n";
$this->count = $max;
while ($max--) {
$row = mysql_fetch_row($result);
$this->name[$max] = sprintf("%s", $row[0]);
$Name[$max] = sprintf("%s", $row[0]);
echo "init \$this->Xame[$max] = $row[0]";
echo " $Name[$max] $this->name[$max]\n";
$regionID[$max] = $row[1];
$constellationID[$max] = $row[2];
$this->ID[$max] = $row[3];
printf("%d:%d/%d/%s\n",$max,$regionID[$max],$constellationID[$max],
$this->name[$max]);
}
================
Line wrap is messing things up a bit.
Was trying sprintf to see if the was a buffer problem coming from mysql.
Problem seems to be the same, regardless.
Also, the names changes ($this->name[] versus $Name[]) are deliberate,
for just in case....
================
Output (debuging):
ROWS returned are: 7
init $this->Xame[6] = 8-TFDX 8-TFDX Array[6]
6:10000003/20000044/8-TFDX
init $this->Xame[5] = B-E3KQ B-E3KQ Array[5]
5:10000003/20000044/B-E3KQ
init $this->Xame[4] = BR-6XP BR-6XP Array[4]
4:10000003/20000044/BR-6XP
init $this->Xame[3] = G5ED-Y G5ED-Y Array[3]
3:10000003/20000044/G5ED-Y
init $this->Xame[2] = O-LR1H O-LR1H Array[2]
2:10000003/20000044/O-LR1H
init $this->Xame[1] = UL-4ZW UL-4ZW Array[1]
1:10000003/20000044/UL-4ZW
init $this->Xame[0] = Y5J-EU Y5J-EU Array[0]
0:10000003/20000044/Y5J-EU
++++++++++++++++++++++++++++++++++++++++++++++
Thanks for your ideas, help, etc..
Maybe it is somethign as simple as "can't do that with echo", but when
the arrays are all single element ( foo_array[0] is only element ) all
statements work as expected.

That 'something' you read was a user comment, not the manual. AFAIK,
getimagesize() *does no* cache.

Without seeing any code, I can only guess that you're doing something
wrong, and need to fix it.

Hello,
We use PHP 4.3.9. 'register_globals = Off' is set in php.ini. I've heard
using 'global' could cause security problems. Is using $GLOBALS still not
more secure than using the 'global' keyword? How should function foo()
obtain the value of $a?
