Help with Combining Array Values

[perezf]

i have an array that has a few of the same values

I just want it to combine all the same values

how can i do that

Array
(
    [0] => 10
    [1] => 16
    [2] => 17
    [3] => 10
    [4] => 11
    [5] => 12
    [6] => 
)

What do you mean by combine the same values, do you mean added together? Or just all occurrences removed but 1?

I just want to remove the duplicates

[RMcLeod]

if you mean remove duplicate values use array_unique

 

<?php
$old_array = array(10, 16, 17, 10, 11, 12);
print_r($old_array);

$new_array = array_unique($old_array);
print_r($new_array);
?>

 

returns

 

Array
(
 [0] => 10
 [1] => 16
 [2] => 17
 [3] => 10
 [4] => 11
 [5] => 12
)

Array
(
 [0] => 10
 [1] => 16
 [2] => 17
 [3] => 11
 [4] => 12
)

 

One thing to note is that this will only work of duplicate value === duplicate value e.g. an array containing 10 and '10' will see these as different values as one is an integer and the other is a string.
