[PHP] Array Sorting
Hi All,
I've got an array which has the following properties:
$file_array[$filename] = array (Date = $Date, size = $size,
permissions = $permissions);
I can quite happily sort the array by filename (using natksort and
natkrsort), which I found on the php manual - and for reference have
included as a PS
What I'm not sure about doing is sorting by say Size or Date?
I've again had a look through the php manual but I'm not sure how to sort by
a property...
Can anyone point me in a direction?
Cheers
Nunners
PS as promised!
function natksort($aToBeSorted) {
$aResult = array();
$aKeys = array_keys($aToBeSorted);
natcasesort($aKeys);
foreach ($aKeys as $sKey) {
$aResult[$sKey] = $aToBeSorted[$sKey];

I think I may have written down my variable structure incorrectly in the first place, which even has me confused... The $file_array[$filename] is I don't think a further array. The sub values are created as follows: $file_array[$filename][Date] = ... $file_array[$filename][Size] = ...

If that's a problem you probably also want to define a Filename element for each item... $file_array[$filename][Filename] = $filename; It's worth noting that if you're not using the fact that they're indexed on the filename it's probably faster to use integer keys instead of strings, but don't quote me on that. I'm not overly familiar with the internals of PHP... yet! Am I also making a mistake by not defining $file_array[$filename]? I don't think so, but would be happy to be corrected! PHP is quite relaxed about these things, but from syntactic(?) completeness and security points of view it should really be initialised to an empty array. -Stut -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

If size is an integer, then, like, just plain old 'sort' should do it, though it's up to you to figure out the multi-dimensional bit. For dates, there are several possiblities... If you Date happens to be Unix timestamp, it's an integer, and is solved by the above. If your Date happens to be in a format not unlike 'Y/M/D' it can be sorted with plain old sort as a string. In situations where Date is in a more natural format, you can use http://php.net/usort and define your own comparison function any which way you want. All that aside, if, like most, this data is coming from the database, you should just use your SQL query to sort the data, if possible, as it will be MUCH more efficient.

[PHP] array sorting
Hi there,
I would like to save some db power by putting values into a file which are often
used. They basicly populate a select field.
So I placed those values into associative arrays:
$code[language] = array(1= php, 2= asp);
Now I would like to sort those for displaying after my preference, not by lets
say alphabet. The easiest thing I could think of, is just to move the entry:
$code[language] = array(2= asp, 1= php);
But this of course does not work. I would like to be able to place values later
on inbetween. So if somebody comes up with a language called .net :-) I would
like to place it in the middle, but I cant get it to work like that :-(
To build the select box I use following code:
select name=education
option value =0 selected---/option
';
# build the select field
for ($i=1; $i = count($code[education]); $i++){
if ($education)
$isselected = ($i == $education) ? selected : ; // select the active row
else
$isselected = FALSE;
printf (option value =\%s\%s%s/option\n, $i, $isselected,
$code[education][$i]);
};
echo'
/select
Has anybody an idea which could help me on that? Thank you for any help.

[PHP] Array Sorting Headaches
Greetings everyone : Having a hard time with this one. I have a multi-dim array $foo[$x][$y]['key'], where $x and $y are numeric. Here is some sample data : Array ( [$x] = Array ( [0] = Array ( [invoiceid] = 11842 [product] = myproduct [domain] = foo.net [expires] = February 28, 2004 ) [1] = Array ( [invoiceid] = 10295 [product] = myotherproduct [domain] = foo.net [expires] = December 9, 2003 ) [2] = Array ( [invoiceid] = 10202 [product] = product1 [domain] = foo.bar [expires] = January 19, 2003 ) [3] = Array ( [invoiceid] = 10005 [product] = product2 [domain] = foo.bar [expires] = December 11, 2002 ) ) ) I need to filter the results so that I get the latest expiry date for each product. The expires field actually contains a timestamp. So for the sample array above, the resultant array would have only keys 0 and 2, filtering out all the rest. There are around 180+ main entries, with any number of sub entries, but each sub entry has the same four keys. Any ideas? Getting a rather large headache mulling over this.

[PHP] Array Sorting, 2 items...
Hi, Trying to accomplish: I want to sort my array by two columns. The array is setup: Array ( [0] = Array ( [0] = CHECKING [ba_type] = CHECKING [1] = 10132200 [loan_number] = 10132200 [2] = 1049 [loan_id] = 1049 [3] = MONICA [first_name] = MONICA [4] = MERCHANT [last_name] = MERCHANT [5] = 2003-07-17 16:15:32 [approved_date] = 2003-07-17 16:15:32 [6] = ACH Debit [type] = ACH Debit ) [1] = Array ( [0] = CHECKING [ba_type] = CHECKING [1] = 10154654 [loan_number] = 10154654 [2] = 1055 [loan_id] = 1055 [3] = RICH [first_name] = RICH [4] = LABO [last_name] = LABO [5] = 2003-07-17 16:15:32 [approved_date] = 2003-07-17 16:15:32 [6] = ACH Debit [type] = ACH Debit ) ) What I'd like to happen is first sort by ba_type, and then sort by loan_number, so that I end up with a nice output similar to; CHECKING 101234 CHECKING 101544 CHECKING 101573 SAVINGS 101112 SAVINGS 101224 VISA 101110 VISA 101998 Keep everything groupped together in their respective ba_type, and put the numbers in numeric order. I've looked at usort, and many examples of it.

RE: [PHP] Array Sorting, 2 items...
Hi,
Yeah, I did get it from a mysql_fetch_array(). I have:
ORDER BY
payment_methods.ba_type ASC,
loan_info.loan_number ASC
However, what it does is first orders it by ba_type, then it goes through
and re-orders it be loan_number, not keeping the ba_type order intact. I
would have much rather handled it all with the SQL, but it just doesn't seem
to work. Here's the entire query:
SELECT payment_methods.ba_type, loan_info.loan_number, loan_info.id AS
loan_id, cust_info.first_name, cust_info.last_name,
transactions.approved_date, payment_types.type FROM loan_info, cust_info,
transactions, payment_methods, payment_types WHERE payment_methods.id =
transactions.payment_method AND payment_types.id = transactions.trans_type
AND cust_info.id = loan_info.cust_id AND transactions.loan_id = loan_info.id
AND transactions.trans_type = 1 AND (transactions.approved_date =
'2003-07-09 00:00:00' AND transactions.approved_date = '2003-07-22
23:59:59') AND (loan_info.loan_number LIKE '101%' OR loan_info.loan_number
LIKE '136%' OR loan_info.loan_number LIKE '707%') GROUP BY loan_info.id
ORDER BY loan_info.loan_number ASC
Maybe I'm doing something wrong there?

I have an array that looks like this: $i = 0; $item[$i] = array( 'link' = 'http://...', 'image' = '/images/image.jpg', 'title' = 'some title', 'price' = '$14.00', 'cat'= 'Frames', 'author' = 'Pinochio', 'artist' = '', 'asin' = '010101', 'manufacturer' = 'Post' ); $i++; $item[$i] = array( 'link' = 'http://...', 'image' = '/images/something.jpg', 'title' = 'this is fun', 'price' = '$2.99', 'cat'= 'Card', 'author' = 'Mickey', 'artist' = '', 'asin' = '1116221', 'manufacturer' = 'Kraft' ); $i++; etc., etc. I would like to sort $items based on the manufacturer of each array within. So that, in the above example, the second one would come before the first. Is there a way to do that? -- H| I haven't lost my mind; it's backed up on tape somewhere. + Ashley M.

Re: [PHP] Array Sorting
Use usort. This function should do the work:
function cmp ($a, $b) {
if ($a['manufacturer'] == $b['manufacturer']) return 0;
return ($a['manufacturer'] $b['manufacturer']) ? -1 : 1;
}

I would like to sort $items based on the manufacturer of each array
within. So that, in the above example, the second one would come before
the first. Is there a way to do that?

That worked like a charm, once I figured out that making the comparison instead of I would get an ascending sort instead of the descending one. Now, can I do multiple sorts?

Re: [PHP] Array Sorting
Yes, simply don't return 0 when the manufacturers are equal, but
continue with other checks:
function cmp ($a, $b) {
if ($a['cat'] == $b['cat']) {
// return 0; -- not anymore, but go on to compare manuf.
if ($a['manufacturer'] == $b['manufacturer']) {
if ($a['title'] == $b['title']) {
// even title is the same, return 0
return 0;
}
return ($a['title'] $b['title']) ? -1 : 1;
}
return ($a['manufacturer'] $b['manufacturer']) ? -1 : 1;
}
return ($a['cat'] $b['cat']) ? -1 : 1;
}

[PHP] Array Sorting
I have looked through php.net and the books that I have and I am confused, so I hope that someone can help me out here. I am trying to sort an array that I have. I use a while statement to fill the array: $teams[++$i][team_id]=$row-team_id; $teams[$i][name]=$row1-name; $teams[$i][team_sea_id]=$row-team_sea_id; Everything goes in the array as it should, so no problem there. I just want to know how do I sort the array by the name column? Thanks In Advance Steve -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
