在PHP如何分配特定陣列鍵的主陣列

Question

我得到了以下O/P

$test1=["12","54","87","98"]; 
$test2=["1","5","8","9"]; 

在這如何可以在連接上述兩個變量的一個變量像下面

1是12的鍵， 5是54鍵， 8是87鍵， 9是98鍵，

Answer 1

嘗試這種情況：

$test1=["12","54","87","98"]; 

$test2=["1","5","8","9"]; 

$a = array_combine($test2, $test1); 

echo "<pre>"; 

print_r($a); 

exit; 

希望這會有所幫助。

和平！的xD

Answer 2

你可以試試這個

$test1=["12","54","87","98"]; 
$test2=["1","5","8","9"]; 


$new_array = array(); 

$i = 0; 
foreach($test2 as $key=> $value) 
{ 
    $new_array[$value] = $test1[$i]; 
    $i++; 
} 

echo '<pre>'; 
print_r($new_array);
