benchmarks can be hazardous, but lets look at them at their most basic
level. By this

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.

Kevin,
I'm just curious to know how to did you do that benchmark.

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

If you're splitting your search string into discrete words, most
search engine logic doesn't require quotes. Typically, quotation
marks combine multiple words into single expressions, which makes
sense with "John Johnston" but not with "John" "Johnston".
But since you requested the quotes I'll include them:
Here's one way to convert an incoming word series for a search:
// get the entered text
$sEnquiry = $_GET["searchenquiry"];
RESULT: [ john johnston ]
// protect against input attacks here
...
// remove whitespace from beginning & end
$sEnquiry = trim($sEnquiry);
RESULT: [john johnston]
// replace internal whitespace with single spaces
$sEnquiry = preg_replace("/\s+/", " ", $sEnquiry);
RESULT: [john johnston]
// replace each space with quote-space-plus-quote
$sEnquiry = str_replace(" ", "\" +\"", $sEnquiry);
RESULT: [john" +"johnston]
// add beginning & ending delimiters
$sEnquiry = "+\"" . $sEnquiry . "\"";
RESULT: [+"john" +"johnston"]

Hi all,
I am postilng pictures up on a website. So far I have a picture per
page. This will get not be very efficient as time goes on. Is there
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.
Thanks,

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.

this might give you some ideas:

you could do it in flash too:

there is probably something already out there to do what you want ;)

Sure you can, Paul. See

There are 5 thumbnails and they all link to photo.php to display the

Check out http://gallery.menalto.com/ There is a way to watch a
slideshow in a single page, but it uses a Java component.
http://www.akehrer.com/ffgallery/ is an Ajax and PHP photo gallery (it
resembles Lightbox), but it doesn't have the action that you require.
http://www.frwrd.net/minishowcase/ is another Ajax attempt.

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.

Can you call getimagesize() multiple times in one script? I'm trying to
use it multiple times but it only seems to work in the first loop I call
it in. I read something in the docs about it cacheing the results and
didn't know if this has something to do with it.
I also tried creating an array out of the results I get from it but it
will only output the size values when it's building the array, never when
I try to loop back through it and output the values.
Thanks,

That 'something' you read was a user comment, not the manual. AFAIK,
getimagesize() *does no* cache.
I also tried creating an array out of the results I get from it but it
will only output the size values when it's building the array, never when

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?
====
<?php
$a = 'one';
foo();
function foo () {
global $a;
echo "a is $a";
}
?>
