Q:

Convert array into simple 1 level array in PHP

A simple thing to do, but I forgot how to convert
Array
(
    [0] => Array
        (
            [hashcode] => 952316176c1266c7ef1674e790375419
        )

    [1] => Array
        (
            [hashcode] => 5b821a14c98302ac40de3bdd77a37ceq
        )

)

into this:
Array (952316176c1266c7ef1674e790375419, 5b821a14c98302ac40de3bdd77a37ceq)

A:

I know this is premature but since this is coming soon I figured I throw this out there.  As of (the not yet released) PHP 5.5 you can use array_column():
 $hashcodes = array_column($array, 'hashcode');

A:

Try this :
$array  = array(array("test"=>"xcxccx"),array("test"=>"sdfsdfds"));

$result = call_user_func_array('array_merge', array_map("array_values",$array));

echo "<pre>";
print_r($result);

Output: 
Array
(
    [0] => xcxccx
    [1] => sdfsdfds
)
