Give me an example:
<code>$arr = array( '175' => '金针菇' '100' => '银针菇' ); $arr2 = array( '65' => '白萝卜' '67' => '黑萝卜' '84' => '黄萝卜' '100' => '银针菇' '90' => '大萝卜' '175' => '金针菇' ); </code>
The final effect is like this:
<code>$arr3 = array( '175' => '金针菇' '100' => '银针菇' '65' => '白萝卜' '67' => '黑萝卜' '84' => '黄萝卜' '90' => '大萝卜' );</code>
Please tell me, how to implement such an algorithm?

This question has been closed. I wrote it myself. When I asked the question, I thought it was complicated. After I calmed down, I realized how simple it is. I’ll post the code:
<code>foreach ($arr2 as $key => $value) { if(!in_array($value, $arr)) { $arr[$key] = $value; } } var_dump($arr);</code>
<code>return($arr + $arr2);</code>
