[PHP] Sorting an array
I need help to know how to sort the words / phrases in my array. Variable name: $words_used print_r( $words_used ); Current output: Array ( [187] => Sin [249] => Punished [98] => Sanctuary [596] => Sing [362] => Anointing Oil ) Desired result: Alphabetical sort: Array ( [362] => Anointing Oil [249] => Punished [98] => Sanctuary [187] => Sin [596] => Sing ) The #’s are the auto_increment value of the word in the mySQL database. The number is not representative of alphabetical order, but the order it was added to the database. Thank you for your assistance.

I want to sort the main array based on the value of key1 for each

oh. well.. how were you trying natcasesort()?
With the example provided in the manual:
$array1 = $array2 = array('IMG0.png', 'img12.png', 'img10.png',
'img2.png', 'img1.png', 'IMG3.png');
//...
natcasesort($array2);
print_r($array2);
should help.

[PHP] sorting an array..dont know numeric or alpha-numeric
Hi,
I have a function that reads jpg files (thumbnails)
from a directory and puts all the files names into an
array...I want to sort that array by the filename,
problem is, I dont know if filenames will be pure
numeric (eg 001.jpg,002.jpg) or alpha-numeric
(asdf001,asdf002)
It HAS to be sequential from small to big (eg: 0-10)
as I am making static html pages from them further
down the program.
Looking in the manual I have tried sort() without any
luck, then looking further I found natcasesort() which
would be perfect for my needs right now, but cant get
it to work :-(
Below is the function (its not big)

Nope. My pattern is legitimate. Within a range, if the first character
is a closing-square-bracket ']', it is treated as the literal character
and not as the end of range. If the range starts with a negation '^',
then the same rule applies to the second character.
This is also a sad indication that I really know my regular expressions,
or I need a vacation. :-)

Do these change all the time or are they rather static? I would
suggest using this routine to generate the list to be used in your
program, instead of doing this on the fly.

Thank you, that will certainly work :8]. Does
anyone have any thoughts how to make it faster? It is
not VERY critical, because the calculation will be
done only once, at initialization, but...well, you
know :8].
* * *
How about...if I count the number of ']'
in string and then add it to the strlen - (the
number of ']' x 2)? There are no [ nor ] in these
except in the character range parts. Does that
look faster than applying regular expression?

I want to sort it comparing to the

[wh]ood is 4 characters, moon is 4 characters.
There are only letters of the alphabet and

[PHP] Sorting an array by value length.
Hey all -
I've been scouring the php.net site for a few hours now trying to find a
viable way to sort a single dimensional array( array('0'=>'fddfsdsfdds',
'1'=>','d','2' => 'gofofle'); ). so that the longest lengthed
item is at the top, and the smallest lengthed item is at the bottom
is there a function to do this... example:
$arrayToSort = array('0' => 'shorter_length', '1' =>
'longer_than_longer_than_shorter_length', '2' =>
'longer_than_shorter_length');
and I would like to get... whether the keys change or not..
$arrayToSort[0] == 'longer_than_longer_than_shorter_length';
$arrayToSort[1] == 'longer_than_shorter_length';
$arrayToSort[2] == 'shorter_length';
any ideas?

[PHP] sorting an array
I am having problems sorting a multi-dimensional array. I am hoping that
somebody can help me figure out what I am doing wrong. It should sort on
the "field" than on the "fac". Here is my code:
-start code-
$sortterm;
get_locations();
function cmp ($a, $b) {
GLOBAL $sortterm;
return strcmp($a[$sortterm], $b[$sortterm]);
}
function get_locations(){
GLOBAL $sortterm;
$i="1";
while(($row=mysql_fetch_object($result))){
$locs[$i][loc_id]=$row->loc_id;
$locs[$i][fac]=$row->fac;
$locs[$i++][field]=$row->field;
}
reset($locs);
$sortterm="field";
usort($locs, "cmp");
reset($locs);
$sortterm="fac";
usort($locs, "cmp");
reset($locs);
while (list ($key, $value) = each ($locs)) {
echo $locs[$key][loc_id].", ".$locs[$key][fac].",
".$locs[$key][field]."\n";
}
}
-end code-
Here is how it comes out when run:
12, Johnson County Community College, C
11, Johnson County Community College, B
13, Johnson County Community College, D
14, Johnson County Community College, E
10, Johnson County Community College, A
8, Johnson County Girls Athletic Assoc, D
6, Johnson County Girls Athletic Assoc, B
7, Johnson County Girls Athletic Assoc, C
5, Johnson County Girls Athletic Assoc, A
9, Shawnee Civic Center, 1
1, Tomahawk Sports Dome, 1
2, Tomahawk Sports Dome, 2
3, Tomahawk Sports Dome, 3
4, Tomahawk Sports Dome, 4
As you can see, the fac is sorted correctly, but the field isn't.
Thanks
Steve

Re: [PHP] Sorting an array.
Sounds like it'd be a lot easier to let MySQL do the calculation and
sorting.
$userLatitude = 50;
$userLongitude = 70;
$sql = "select companyname, blah, blah,
ceiling(sqrt(pow(69.1 * (latitude - $userLatitude), 2) +
pow(53 * (longitude - $userLongitude), 2))) as distance
from mytable order by distance";

Re: [PHP] Sorting an array.
Perhaps you could store $row in an array of arrays; store only $row within
100 miles. Add another field, Distance, to each row that holds the
calculated distance. Then, after creating the array, sort the final array
by Distance.

RE: [PHP] Sorting an array of arrays....
Does anyone have an example of code that does this, I have been trying to
decipher the instructions on the use of uasort but it does not make a hole
lot of sense. They are using static keys and sorting by one of the array
elements of each of there static keys. It does not seem like one should have
to do it this way. I need it to go through each key and sort the keys based
on a value in the array held in that key.
Thanks
Mike

Good day,
uasort() should do what you need.

There's an example for the usort function that does something similar to
what you want, in fact.

[PHP] Sorting an array
I'm trying to sort a listing of albums alphabetically for LyricsList.com, the problem is that I want the initial 'The' and 'A' in some albums (A Hard Days Night, The Wall) to be ignored. So that the list will look like: Abbey Road Dark Side Of the Moon The Final Cut A Hard Days Night Kill 'em All The Wall ABC order, 'A' and 'The' negated. The info comes from a database, in three calls: // call albums that begin with letter $letter $query = "SELECT * FROM albums WHERE album LIKE '$letter%' ORDER BY album"; $result = mysql_query($query) or die(mysql_error()); // call albums that begin with letter A $query_a = "SELECT * FROM albums WHERE album LIKE 'a' ORDER BY album"; $result_a = mysql_query($query_a) or die(mysql_error()); // call albums that begin with letter T $query_t = "SELECT * FROM albums WHERE album LIKE 't' ORDER BY album"; $result_t = mysql_query($query_t) or die(mysql_error()); So I need to get just the albums from $result_t that begin with 'The ' (easy regex) and from $result_a that begin with 'A ' (easy regex), but puting the three of them in order is proving beyond my skill.
