Re: [PHP] replying to list
Not really i think, because by replying it just direct reply to the OP, while other systems like google groups for example by replying you just post to the list, and actually make more sense. the easy way is to hit reply and change the "to" into php-general@lists.php.net or reply to all and replace "to" with the "cc". I think the best practice is to take this 5 second to take care of this in order to avoid duplicate message to others. cheers Nick On Apr 21, 2010, at 12:45 PM, Karl DeSaulniers wrote: > Exactly. > :) > > Karl > > On Apr 21, 2010, at 5:38 AM, David McGlone wrote: > >> Maybe it's not how the list is set up, but instead how people are >> replying to the list. > > Karl DeSaulniers > Design Drumm > http://designdrumm.com > > > -- > PHP General Mailing List (http://www.php.net/) > To unsubscribe, visit: http://www.php.net/unsub.php > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] escape \n
Hello guys i am trying to figure out what is worng with thoose special escaped character, like \n \t \r ... As i cannot make them working. The browser doesn't display them, but doesn't eithr crate a new line, or else. I am using them fro example like this: print: "this shoudl be on a line \nwhile this on a new line"; I've searched google and saw man people struggling with this, but apparently not a clear answer to whymaybe is a stupid beginner question, but i would just like to know. (Personally i solved for the moment by printing out or , but i would like to understand this. Cheers, Nick

[PHP] multi dimensional array question
hello everybody here is my array(s)
$us_census = array('NY' => array('New York' => 8008278),
'CA' => array('Los Angeles' => 3694820,
'San Diego' =>
1223400),
'IL' => array('Chicago' => 2896016),
'TX' => array('Houston' => 1953631,
'Dallas' =>
1188580,
'San Antonio'
=> 1144646),
'PA' => array('Philadelphia' => 1517550),
'AZ' => array('Phoenix' => 1321045),
'MI' => array('Detroit' => 951270));
print
"StateCityPopulationTotal";
// $state is the key and $states is the value
foreach ($us_census as $state => $cities) {
// $state is the key and $habitant is the value
foreach ($cities as $city => $habitants){
print
"$state$city$habitants";
}
}
Now i also want to be able to count the total population per state, i am
stucked...

Re: [PHP] multi dimensional array question
thanks Piero!
i was trying to solve an excercise on "learning php5" (O'reilyl) book.
I am happy abotut his solution with the array_sum funtion you suggested, and my
multidimensional array make much more sense to mee then they suggested solution
that also much more line of code comapred...
look: my solution (with Piero suggeston): and ont he bottom the book solution.
what do u say is the best one? why? i am learning so i am interested in
understanding why a solution can be better then an other...
$us_census = array('NY' => array('New York' => 8008278),
'CA' => array('Los Angeles' => 3694820,

'IL' => array('Chicago' => 2896016),

print
"StateCityPopulationTotal";
foreach ($us_census as $state => $cities) {
foreach ($cities as $city => $habitants){
$tothabitants += $habitants;
print
"$state$city$habitants";
}
}
print "$tothabitants";
foreach ($us_census as $state => $cities) {
$population_per_state = array_sum($cities);
print "$state $population_per_state";
}

the book solution:
$population = array('New York' => array('state' => 'NY', 'pop' => 8008278),
'Los Angeles' => array('state' => 'CA', 'pop' => 3694820),
'Chicago' => array('state' => 'IL', 'pop' => 2896016),

$state_totals = array( );
$total_population = 0;
print "CityPopulation\n";
foreach ($population as $city => $info) {
$total_population += $info['pop'];
$state_totals[$info['state']] += $info['pop'];

foreach ($state_totals as $state => $pop) {
print "$state$pop\n";
}
print "Total$total_population\n";
print "\n";

[PHP] Joomla FrameWork ::
I am trying to understand how the joomla framework works, i see an heavy usage
of " :: " in its code, here an example:
function edit ()
{
JRequest::setVar('view, 'single');
$this ->display();
}
from my really basic php understanding in the function edit i call a function
setVar() and i pass the paramter 'view' and 'single' in it then the output
($this) is passed to the display() function.
My question is what does :: means? an more precisely referring to the example:
JRequest::setVar('view, 'single'); how do you read it and how do you manage
it?
Cheers, Nick

posting the question, i just haven't started yet classes and methods...;-)
