how do i replace a character in my array with another character?

Question

i have a array - the output of my array looks like this:

Array
(
    ["US"] => 186
    ["DE"] => 44
    ["BR"] => 15
    ["-"] => 7
    ["FR"] => 3
)

and i want to replace the "-" with "other"

so it should look like this at the end:

Array
(
    ["US"] => 186
    ["DE"] => 44
    ["BR"] => 15
    ["other"] => 7
    ["FR"] => 3
)

could someone help me with this? str_replace havent worked with me... and if you could i want to have the "other" part of the array at the bottom - like this:

Array
(
    ["US"] => 186
    ["DE"] => 44
    ["BR"] => 15
    ["FR"] => 3
    ["other"] => 7
)

thanks :)

current code:

 $array_land = explode("\n", $land_exec_result);
 $count_land = array_count_values($array_land);
        arsort($count_land);
        $arr['other'] = $count_land["-"];
        unset($count_land["-"]);

Simple like that:

$array["other"] = $array["-"];
unset($array["-"]);

At the end, the array will be like this:

Array
(
    ["US"] => 186
    ["DE"] => 44
    ["BR"] => 15
    ["FR"] => 3
    ["other"] => 7
)

i edited my question :) this in your answer havent worked for me :/ – PHPprogrammer42 Jan 05 '16 at 09:44
php just gives me an: Undefined index: - ( so php doesnt find the "-" character ) – PHPprogrammer42 Jan 05 '16 at 09:48
Are you sure the array $count_land have the "-" index? If you print_r the $count_land what will be the output? – Vitor Villar Jan 05 '16 at 09:52
what you see in my question is the output of $count_land :) – PHPprogrammer42 Jan 05 '16 at 09:58
Have you tried escape the "-"? Like "\-"? – Vitor Villar Jan 05 '16 at 10:11
yes i did but it still says undefined index :o what really curious is.. i cant explain why php say that "-" is an undefined index – PHPprogrammer42 Jan 05 '16 at 10:17
Let me try here, just a sec. – Vitor Villar Jan 05 '16 at 10:19
Man, here works like a charm. Lets try something. Make a foreach like this: `foreach($count_land as $key => $value) { var_dump($key); }` Whats the value printed when the foreach pass on "-"? It's really one character? – Vitor Villar Jan 05 '16 at 10:30
this gives me a : string(4) ""US"" string(4) ""DE"" string(4) ""BR"" string(3) ""-"" string(4) ""FR"" as an output – PHPprogrammer42 Jan 05 '16 at 10:34
Did you get it? The string are quoted, all of them. So you may need to remove the quotes or do this: `$count_land['"-"']` I think the better way is remove the quotes, look this: http://stackoverflow.com/questions/4228282/how-do-i-remove-quotes-from-a-string – Vitor Villar Jan 05 '16 at 10:37

$arr['other'] = $arr['-'];
unset($arr['-']);

The first command stores the value of your $arr['-'] element in a new element named $arr['other']. When you create a new element this way for an array with named indexes the new element will automatically be placed at the end of the array.

The second command removes the $arr['-'] element from the array. The result will be:

Array
(
    ["US"] => 186
    ["DE"] => 44
    ["BR"] => 15
    ["FR"] => 3
    ["other"] => 7
)

You need to explain your answer. SO doesn't exist to just answer questions but teach people how to code. – Machavity Jan 04 '16 at 15:21
