PHP合并相应键中的数值数组的值

Question

So consider an array with my 3 favorite fruits:

$array1 = array("Apple", "Banana","Raspberry")

I want to merge it with their own beautiful and natural color

$array2 = array("Green ", "Yellow ","Red ")

So that the results would look like

([0] => Green Apple [1] => Yellow Banane [2] => Red Raspberry) 

I need something to be scalable (2 to 6 keys, always the same between arrays)

What I tried and results

• array_combine($array2,$array1)

  Result: Array ( [Green ] => Apple [Yellow ] => Banana [Red ] => Raspberry )

• array_merge($array2,$array1)
  Result: Array ( [0] => Green [1] => Yellow [2] => Red [3] => Apple [4] => Banana [5] => Raspberry )

• array_merge_recursive($array2,$array1)
  Result: Array ( [0] => Green [1] => Yellow [2] => Red [3] => Apple [4] => Banana [5] => Raspberry )

Answer 1

You actually should loop through arrays to combine them.

$combinedArray = array();
foreach ( $array1 as $key=>$value ) {
    $combinedArray[$key] = $array2[$key] . ' ' . $array1[$key];
}
