merge array problem

Hello,

I have 2 array:

$pids = array ( 40 => 0, 41 => 1, 43 => 2, 42 => 3 );

$ids = array( $pids , 678=>'', 444=>''); 

PHP:

I want to join the two arrays.
How do I get the following output in the second array:

$result = array (40 => '', 41 => '', 43 =>'', 42 => '', 678=>'', 444=>'');

Thank you!

 

$array = array_merge(array_keys($pids), array_keys($ids));

PHP:

like this?

 

<?php
$array1 = array("color" => "red", 2, 4);
$array2 = array("a", "b", "color" => "green", "shape" => "trapezoid", 4);
$result = array_merge($array1, $array2);
print_r($result);
?>
