Convert array into simple 1 level array in PHP

Question

A simple thing to do, but I forgot how to convert

Array
(
    [0] => Array
        (
            [hashcode] => 952316176c1266c7ef1674e790375419
                


        

Answer 1

A good ol' loop solves :)

 'hash' ),  
    array( 'hashcode' => 'hash2' ), 
);

$flat = array();

foreach ( $array as $arr ) {
    $flat[] = $arr['hashcode'];
}

echo "
";

print_r( $flat );

?>
