PHP sort array with czech encoding, case insensitive and without re-indexing

Question

I'm having multi-dimensional problem :) I have an array, which contains this:

array (33)
18 => "D3 0309/II Ševětín – Borek" (31)
19 => "D3 0311 TŘEBONÍN – KAPLICE NÁDRAŽÍ" (41)
25 => "D3 0312/I Kaplice nádraží - Nažidla" (39)
26 => "D3 0312/II - Nažidla - Dolní Dvořiště státní hranice" (59)
27 => "D3 TEST" (7)
15 => "D30310_Hodějovice-Třebonín" (29)
30 => "D4 Lety - Čimelice" (19)
29 => "D4 Milín - Lety" (16)
32 => "D4 Mirotice rozšíření" (25)
20 => "D4 křižovatka II/118 – Milín, DSP" (38)
31 => "D4 Čimelice - Mirotice" (23)
13 => "D6 Lubenec obchvat 1.etapa" (26)
23 => "D6 Nové Strašecí-Řevničov" (30)
6 => "D6 Řevničov obchvat" (21)
33 => "D8 MÚK Zdiby – rozšíření Prosecké radiály, etapa 2 – direktní větev" (80)
12 => "I/21 Trstěnice - Drmoul" (24)
2 => "I/37 Chrudim - obchvat, úsek křiž. I/17 - Slatiňany" (55)
44 => "Jirka (ostatni nesahat) - import Valbek" (39)
17 => "Klatovy" (7)
37 => "Letiste Pribram" (15)
24 => "Optimalizace traťového úseku Mstětice – Praha - Vysočany" (63)
34 => "Radost II" (9)
7 => "SOKP 512 "D1-Jesenice - Vestec" Psáry - přeložka silnice II/105" (66)
14 => "Stavba - návod" (15)
43 => "Test ě+ščřžýáíé0123465789 sss" (38)
4 => "Testovací stavba" (17)
39 => "Videnska" (8)
38 => "Vratislavice" (12)
36 => "Zvýšení kapacity trati Nymburk – Mladá Boleslav, 2.stavba" (63)
41 => "jirka test 4" (12)
22 => "test" (4)
35 => "test-D4 křižovatka II/118 – Milín" (38)
45 => "čtest" (6)

At first, I must keep indexes, because they are taken in select query as ID. Second, I have to sort that case-insensitive and third, I need to sort it with czech encoding. I've searched for some help, but nothing worked for me. I will include my current code, which uses uasort with strcoll , but it sorts case-sensitive and doesn't even work for czech encoding...

setlocale(LC_COLLATE, 'cs_CZ.utf8');
uasort($options, 'strcoll');

also tried this, but with same result...

setlocale(LC_COLLATE, 'cs_CZ.utf8');
asort($options, SORT_LOCALE_STRING);

So I finally solved it with the way I wanted to avoid.

$sort = function ($a, $b){
    static $czechCharsS = array('Á', 'Č', 'Ď', 'É', 'Ě' , 'Ch' , 'Í', 'Ň', 'Ó', 'Ř', 'Š', 'Ť', 'Ú', 'Ů' , 'Ý', 'Ž', 'á', 'č', 'ď', 'é', 'ě' , 'ch' , 'í', 'ň', 'ó', 'ř', 'š', 'ť', 'ú', 'ů' , 'ý', 'ž');
    static $czechCharsR = array('AZ','CZ','DZ','EZ','EZZ','HZZZ','IZ','NZ','OZ','RZ','SZ','TZ','UZ','UZZ','YZ','ZZ','az','cz','dz','ez','ezz','hzzz','iz','nz','oz','rz','sz','tz','uz','uzz','yz','zz');

    $A = str_replace($czechCharsS, $czechCharsR, $a);
    $B = str_replace($czechCharsS, $czechCharsR, $b);

    return strnatcasecmp($A, $B);
};
uasort($options, $sort);

Write a sort function and lower first.

setlocale(LC_COLLATE, 'cs_CZ.utf8');
function sortme ($a,$b){
    $a = mb_strtolower($a);
    $b = mb_strtolower($b);
    return strcoll($a,$b);
}

$options = array('Ša','šb','Šc','šd');
uasort($options, 'sortme');
print_r($options);

//result with strtolower
//Array ( [0] => Ša [1] => šb [2] => Šc [3] => šd )

//result without mb_strtolower
//Array ( [0] => Ša [2] => Šc [1] => šb [3] => šd )

That works as case-insensitive, but unfortunately čtest is still last item in array, although it should be first..

HS1993 Over a year ago

after edit: but when you add something without czech encoing, like for example aa, bb, zz, yy, items with special characters are still at last positions..

mmh, that wired. have to look more into it

solved, look at my answer, I've searched through some czech forums, and this seems to be the only solution unfortunately..
