如何合併數組到單一陣列在PHP

Question

有兩個數組：

第一陣列：

Array 
(
    [0] => EXTRA 
    [1] => CURRICULAR 
) 

第二陣列：

Array 
(
    [0] => ACTIVITIES 
    [1] => 50 
    [2] => 35 
    [3] => THIRTY 
    [4] => FIVE 
    [5] => PASS 
) 

所需的輸出：

Array 
(
    [0] => EXTRA CURRICULAR ACTIVITIES 
    [1] => 50 
    [2] => 35 
    [3] => THIRTY 
    [4] => FIVE 
    [5] => PASS 
) 

兩個陣列應該是動態的，我需要追加到第一到第二，請幫我

Answer 1

您需要implode你的第一個陣列，並將結果在前面加上你的第二個數組的第一個值：

$array1 = array('EXTRA', 'CURRICULAR'); 
$array2 = array('ACTIVITIES', 50, 35, 'THIRTY', 'FIVE', 'PASS'); 

$string = implode(' ', $array1); 
$array2[0] = $string . ' ' . $array2[0]; 

var_dump($array2); 

結果：

array (size=6) 
    0 => string 'EXTRA CURRICULAR ACTIVITIES' (length=27) 
    1 => int 50 
    2 => int 35 
    3 => string 'THIRTY' (length=6) 
    4 => string 'FIVE' (length=4) 
    5 => string 'PASS' (length=4)
