How to re-index an array? [duplicate]

Question

I have a array

Array (
    [1] => Vice President
    [3] => Secretary
    [5] => Treasurer
)

I want make it change to

Array (
    [0] => Vice President
    [1] => Secretary
    [2] => Treasurer
)

I have try us php for loop function

$ub_new_arr_sort = array();
for ($i3 = 0; $i3 < count($ub_new_arr); $i3++) {
    $ub_new_arr_sort[] = $ub_new_arr[$i3];
}

but seem like not work at all, any idea?

For the record, "your" way did not work because you're iterating over the fictional indexes 0..2. However, the array used the indexes 1, 3, and 5. The foreach construct would have worked, although @Francois Deschenes' answer is more elegant, IMO. — jensgram

Just use array_values.

$array = array_values($array);

Use foreach instead of for to be 'key independant':

foreach($oldarray as $position){
    $newArray[] = $position;
}
print_r($newArray);

@wyman Just so that you understood what was wrong in your code: your for was looping from 0 to count(), so the values were 0,1,2 while keys actually are 1,3,5. In fact PHP was generating E_NOTICEs when you tried to read non-existent keys 0 and 2. Always keep error_reporting=E_ALL|E_STRICT in php.ini on your development machine, it will prevent you from making obvious bugs.
