在PHP如何分配特定阵列键的主阵列

Question

我得到了以下O/P

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

在这如何可以在连接上述两个变量的一个变量像下面

1是12的键， 5是54键， 8是87键， 9是98键，

Answer 1

尝试这种情况：

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

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

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

echo "<pre>"; 

print_r($a); 

exit; 

希望这会有所帮助。

和平！的xD

Answer 2

你可以试试这个

$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);
