The one thing I have found in building websites is that you should
always create the site to the lowest IQ. Make it simple because there
are users out there that might not know that you can hit enter (or
return) to activate a search.

That's my 2 pents worth.

Re: PHP5 Speed Issues

Hi everyone!

Generaly author of the first e-mail is right. Ofcource, crawling over the
code and getting out of it a few milliseconds off doesn't make it worth, but
you can learn what is good and what is bad and write your code correctly
from the start.
Why not to use
foreach ($data as &$value)
if it's better - faster and takes less memory. That's just a habbit on code
style.
I can bet, that nobody knows or remembers that echo has alternative syntax,
with works faster and is easier to write if you cave to echo a complex
string with many variables and static text, for example

The ordinary:
echo 'Hi! My name is '.$_GET['name'].'. I'm '.$_GET['age'].' and I live in
'.$_GET['country'].'.';

The alternative:
 echo 'Hi! My name is', $_GET['name'], '. I'm ', $_GET['age'], ' and I live
in ', $_GET['country'], '.';

I have an aplication with doesn't eat all CPU, just about 50-60%, but it
eats all 3GB of ram. And not because it is poorly written. It serves ~160
000 - 170 000 requests/hour, that's ~3 960 000 hits a day + another 600 000
hits to the application's WEB part. Just one server could handle, but it
can't because of WEB server's FastCGI implementation (they have a patch for
that soon released).
Just ONE Intel E6600 server with Lighttpd and PHP can handle such load if
the code is optimised and written correctly.

Have the button, but make it tiny.

There are always some users too new to know that they don't need a
button.

The rest can ignore the tiny bubbles.  I mean button. :-v

I HATE pages with js forms (just because its js) and "uncomplete" forms. I 
love surfing and finding information with just my trackball. The imense power 
of linux gpm mark/copy - paste, makes us undeniable lazy.
I actually got to go looking for the extra :'
'
to fetch'n copy the "virtual" enter... takes a few extra ms at than, but I 
don't have to move a finger.
If I got the button I don't have to think about it, without it I got no 
choice.

foreach questions

Hello;
I have this section of code:

   <at> include('tmp_index.php');
    foreach($index as $key -> $value)
           {
            if($input == $key)
              {
               $target_file = $value;
              }
           }
And I am getting this error:
Fatal error: Cannot access empty property in <path>/confirmation.php on 
line 131

Several questions:
How long can an index be in an associative array? (the indexes I use in 
this array are 32 character hashes)
Can it start with a number (since a hash can start with a number)
Can I use $index as an array name? (I do not remember off hand what the 
reserved key words are)
I am not sure what the "empty property" is that it is referring to.
Thank you in advance for info;
Jeff K

I bought the property on line 131 just before you tried to access it. I put up 
a high electric fence, just over the path and theres nothing there yet, but 
working up a mortgage right now. ;D sry. late nite last night.

Thank  you for the response;
I should have known. I don't use this type of loop often enough
to get it straight the first time.

Re: foreach questions

Hello,
the problem is in this part of code $key -> $value
This notation means that you are trying to access property $value on the 
object $key.

Just replace it with $key => $value and you will get the result as expected.

variable substitution

Hello again;
I have two variables declared in the global scope of a script.
$string_a = 'stuff $string_b and more stuff';
$string_b = '';
One is a string with a reference for substitution to the other
string which is empty.
In the processing body of the script are if/if else blocks.
In these blocks I want to use $string_a  and
set $string_b  to a value
if( condition)
{ $string_b = 'by the way;';... etc
so $string_a should read:
"stuff and by the way; and more stuff"
But this substitution will not take place
in the context of the else if block. I do not
want to write $string_a in at least 5 different
if else blocks because it is about 10 lines
intended to be an e-mail message body -> !SPAM.

this script is used to process data sent from a
link in another e-mail message used to validate
and e-mail address.

Q: Is there a way to get the substitution to take
     place here? (by reference, maybe?)

Thank you in advance for info
Jeff K
