Re: [PHP] multidimensional array problems
Ive followed your example on grouping. Im still trying to understand all of
the code but ive made great progess on this with your example. Now I have
one last issue and this will be solved. Ill remind here what Im trying to
achieve
I have a table for leagues, lookup table and team roster. There can be
multiple game types for each game i.e. CoD2 - CTF, CoD2 - SD, CoD2 - TDM.
If a member is playing CoD2 CTF and CoD2 TDM there should be a table for
each game and type showing each member playing that game/type. If a member
is signed up for multiple games/types he/she should have a name listed
under each game/type.
Right now my php script is only sorting by game which is putting the same
person in for each instance of the game instead of sorting through each game
and then type. So here is my code so far and any help is greatly
appreciated.
?php
include (db.php);
$memroster = SELECT inf_league.game, inf_league.type, inf_member.user_name,
inf_member.rank, .
inf_member.country, inf_member.email .
FROM inf_league .
INNER JOIN inf_memberleague ON inf_league.gid =
inf_memberleague.l_id .
INNER JOIN inf_member ON inf_member.user_id =
inf_memberleague.m_id;
$roster = array();
$memrosterresults = mysql_query($memroster)
or die(mysql_error());
while ($record = mysql_fetch_object($memrosterresults)) {
$roster[$record-game][] = $record;
}
ksort($roster);
foreach ($roster as $game = $records) {
print table\n;
print caption{$game}/caption\n;
print thName/th thRank/th thCountry/th thEmail/th\n;
foreach ($records as $record) {
print tr\n;
print td{$record-user_name}/td\n;
print td{$record-rank}/td\n;

Re: [PHP] multidimensional array problems
It's actually quite simple. You simply add another layer of grouping.
General case:
$result = mysql_query(SELECT a, b, c, d FROM foo ORDER BY a, b, c);
while ($record = mysql_fetch_object($result)) {
$roster[$record-a][$record-b][] = $record;
}
ksort($roster);
foreach ($roster as $a = $bfield) {
print $a;
ksort($bfield);
foreach ($bfield as $b = $record) {
print $a: $b;
print_r($record);
}
}
Add real output syntax to taste.

Re: [PHP] multidimensional array problems
It's better to just leave the record as an array and read it that way.
while ($row = mysql_fetch_assoc($result)) {
print trtd{$row['game']}/td td{$row['type']}/td/tr\n;
}
And so on. You're not actually dealing with a multi-dimensional array yet;
$result is an object from which you are extracting data records as
one-dimensional associative arrays.

Actually, I'd suggest doing a PHP-side grouping. See this article for

i print the way your showing it prints for every instance. Im trying to

I have 3 tables in my db, league table, lookup table and member table. Do
you think it would be better possably to do seperate querys and then match

I did go through that, but I can't get it to work and I'm almost
willing to bet it's because of the way the array is built. For example,
the example on that page says that I should be able to do a sort on
$ar[0] and $ar[1], however in my array both of those return 0. In fact,
when I do this:
echo items in array: . count($data) . br /;
for ($i = 0; $i count($data); $i++) {
echo data[$i]: . count($data[$i]) . br /;
}
I get:
items in array: 2
data[0]: 0
data[1]: 0
When I do a print_r($data), I get:
Array
(
[John] = Array
(
[KIRASH] = Array

[0] = 050311_18.00.59__KIRASH.zip

)
S, I'm at a loss here. I think I need to create the array
differently for it to work.

Re: [PHP] Multidimensional Array manipluation...
Hi,
Well, I will be having something like this:
$se5f2254321s65s32s65[] will hold various valus like jan_1,jan-2,jan_3,jan_4
etc and then jan_1 will hold 1, jan_2=2,, jan_3=1 etc etc...
Depending on certain conditions, I want to increment the values of certain
values in the array...like...
for($i=0; $i=count($se5f2254321s65s32s65); $i++)
{
$se5f2254321s65s32s65[$i][jan_1] = 1
}
I want to increment it with 1 and so on for the various other values
Thanx
Best Regards,
Dhaval

RE: [PHP] Multidimensional array construction
I haven't seen the rest of this thread so this may be irrelevant ... but
foreach($array as $key=$value)
{ $array[$key] = fred;
}
... alters an array while traversing it. Your case seems more complicated
but I would have thought nesting foreaches in this way would allow you to
access the original element.
foreach($array as $key1=$value1)
{ foreach($array as $key2=$value2)
{ $array[$key1][$key2] = fred;

Good day,
Thanks to all who replied.
This isn't quite what I needed, though. I _have_ the array (or
delimited
list would do, too). What I need to do is _CREATE_ the array
element
$myarray['foo']['bar']['green']['apple'] and set it to some value.
Actually
traversing said array isn't hard, as you pointed out.
foreach() doesn't work, as it just uses a copy of the original
array. I
think there might be some way to use variable references, but I
haven't
gotten one to work yet.
Any other suggestions?

I did something like this recently. Here's how I did it:
$some_value1 = 'Hello World';
$myarray['foo']['bar']['green']['apple'] = $some_value1;
function get_opt($arr, $keys,$sep=':') {
$var = $arr;
$tmp = split($sep,$keys);
foreach ($tmp as $k = $v) {
$var = $var[$v];
}
if (isset($var)) return $var;
return '';
}
echo get_opt($myarray, 'foo:bar:green:apple');
It needs refining, but it should do the job. That's entirely from
memory, mind you.. it should work, though.

Here's a question for the list:
I have a two-dimensional array; essentially a list of arrays. Each
element
(an array) can have any number of elements. As a small example:
(
( foo , bar , red , apple ),
( foo , bar , red , car),
( foo , green )
)
I would like to traverse this array and place all of the data into
another
multidimensional array. The following statements illustrate how
I'd like
to
do this from the example:
$myarray[foo][bar][red][apple] = $some_value1;
$myarray[foo][bar][red][car] = $some_value2;
$myarray[foo][green] = $some_value3;
Is there any way to easily do this in PHP? I could cheat and use
eval(),
but there is probably a better way. I have thought of using each()
or
references, but nothing has come to mind so far.
Any ideas? Should I just use eval() ?

RE: [PHP] Multidimensional array construction
This might be interesting ... The function extract() allows you to extract all values from an array and prefix them with a specified string. What I didn't know until just a second ago was that you can supply a function as a string, so ... $my_array = array(a,b,c,d,array(a,b,c,d)); $i = 1; extract($my_array,EXTR_PREFIX_ALL,SOMEVAL.$i++); print pre; print $SOMEVAL_1; print $SOMEVAL_2; print $SOMEVAL_3; print $SOMEVAL_4; print $SOMEVAL_5; print /pre; ... will produce: a b c d [Array] Which is cool. Not quite what you wanted, but maybe you could run with it.
