)
[3] => Array

[9] => 0
[10] => 0
)
[4] => Array
(
[0] => 2525

[6] => 1454976000
[7] => Cat. A (Moto)
[8] => 0
[9] => 1
[10] => 0
)
)
I want i new array:
1) if element [0] exists in the array I want to control elements 8, 9 and 10 and if one of this is 1 I want to have 1 in the final array, but I don't want to have the same array 2 times (the index [0] is the key).
My final array shound be:
Array
(
[0] => Array
(
[0] => 2505
[1] => Lima
[2] => Daniels
[3] => 0996995904
[4] =>
[5] => 755971
[6] => 1454284800
[7] => Cat. A (Moto)
[8] => 1
[9] => 1
[10] => 1
)
[3] => Array
(
[0] => 2525
[1] => Lomarca
[2] => Miro
[3] => 0099778877
[4] =>
[5] => 768131
[6] => 1454976000
[7] => Cat. A (Moto)
[8] => 1
[9] => 1
[10] => 0
)
)
I have only one time the index 2505 and 2505 and index 8 and 9 and 10 are 1 for the 2505 and the index 8 and 9 are 1 for the 2525.

this does the job: (assuming that your first array is $arrays and your desired result is $result)
$result = array();
foreach($arrays as $array)
{
if(!isset($result[$array[0]]))
{
$result[$array[0]] = $array;
}
else
{
$result[$array[0]][8] = $array[8] == 1 ? 1 : $result[$array[0]][8];
$result[$array[0]][9] = $array[9] == 1 ? 1 : $result[$array[0]][9];
$result[$array[0]][10] = $array[10] == 1 ? 1 : $result[$array[0]][10];
}
}
but wherever you get your data from, e.g. a database, I would use element[0] as the key, so you don't get multiple entries in $arrays. Another option would be to create a class which holds your data...
