Javascript-[algorithm] how to implement random key-value pairs in the array with the first place?

For example, the final effect of {code...} is as follows: {code...}. how can this algorithm be implemented? Example:

$ Arr = array ('000000' => 'flammulina velutipes ''000000' => 'Silver mushroom '); $ arr2 = array ('65' => 'white radish '67' => 'Black radish '84' => 'yellow radish '100' => 'Silver mushroom'' 90' => 'radish '000000' => 'mushroom ');

The final effect is as follows:

$ Arr3 = array ('20140901' => 'flammulina velutipes '20160301' => 'Silver needle mushroom '65' => 'white radish '67' => 'Black radish'' 84 '=> 'radish '90' => 'radish ');

How can this algorithm be implemented?

The problem has been closed and I wrote it myself. I thought it was complicated when I asked the question. after the problem was solved, I realized it was so simple that I posted the code:

foreach ($arr2 as $key => $value) {    if(!in_array($value, $arr)) {        $arr[$key] = $value;    }}var_dump($arr);

return($arr + $arr2);
