我怎样才能将数组分配给php中的另一个变量？

Question

我在php中定义了一个数组

    $letters = array("A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","W","V","X","Y","Z");

然后我尝试将数组分配给一个将成为数组的新变量,我这样做:

   $new_array = array();
   $new_array =  $letters;

但它不起作用,为什么？

Answer 1

你可以这样做

$new_array = $letters;

您不必指定类型,因为它是隐含的.
