array_unique problem

[Yamakazi]

Hello,

I got an array wich looks something like this:

0 0
1 326
2 382
3 386
4 387
5 388
6 393
7 423
8 424
9 462
10 431
11 432
12 459
13 460
14 461
15 438
16 370
17 373
18 393
19 394
20 423
21 424
22 462
23 427
24 431
25 432
26 459
27 460
28 461
29 438
30 429
31 393
32 394
33 423
34 424
35 462
36 427
37 431
38 432
39 459
40 460
41 461
42 438

After i array_unique this array i got this one:

 
0 0
1 326
2 382
3 386
4 387
5 388
6 
7 423
8 
9 462
10 
11 432
12 459
13 460
14 
15 438
16 370
17 373
18 
19 394
20 

As you can see the function works only halve. He makes an array of 21 entrys. Wich is correct, but in a few cases he replaces the correcdt numbers with a blank?
Does anyone know what goes wrong?

TIA

I've just tried and I got the same bug, strange !

from PHP.NET

PHP 4 >= 4.0.1

BUT

This was broken in PHP 4.0.4!

for me I used my own function which is :

for ($i = 0,$n = count($tab); $i < $n; $i++) $uniqTab[$tab[$i]] = 1;
foreach ($uniqTab as $key => $value) $resultTab[] = $key;

hope this helps 😉

I found a solution to the problem.

I did this

$uniquearr = array_values(array_unique($arr));

And this method seems to work fine. It doesn't leave out any of the values.

Cheers.
