if anyone think we should not modify array_values
i have anohter suggested name:
array_column($array, $whichColumn)
because it's mostly used to get all fields(foreah row) in one column

Description:
------------
old:
Usage: array array_values ( array input )
Purpose: Return all the values of an array
new suggestion:
Usage: array array_values ( array input, [mixed key] )
Purpose: Return all the values of an array
key default to null, which is same as old array_values
if key is_int or is_string
it act like this:
function array_values($input, $key)
{
$ret = array();
foreach ($input as $value) {
$ret[] = $value[$key];
}
return $ret;
}
this is very useful to collect ids
e.g.:
$idrows = db_query_all_rows("select id from table1");
$ids = implode(',', array_values($idrows, 'id'));
$myrows = db_query_all_rows("select .... from table2 where id
IN($ids)");
(db_query_all_rows is custom function which fetch all rows of query
result)
thanks
