<span class="function"><strong>array_replace_recursive()</strong></span> 使用后面数组元素的值替换数组 <code class="parameter">array1</code> 的值。
|
|
如果一个键存在于第一个数组同时也存在于第二个数组，它的值将被第二个数组中的值替换。
|
|
如果一个键存在于第二个数组，但是不存在于第一个数组，则会在第一个数组中创建这个元素。
|
|
如果一个键仅存在于第一个数组，它将保持不变。
|
|
如果传递了多个替换数组，它们将被按顺序依次处理，后面的数组将覆盖之前的值。

<p class="para"> <span class="function"><strong>array_replace_recursive()</strong></span> 是递归的：它将遍历数组并将相同的处理应用到数组的内部值。

</p>
|

<p class="para">
|
|
如果第一个数组中的值是标量，它的值将被第二个数组中的值替换，它可能是一个标量或者数组。如果第一个数组和第二个数组中的值都是数组，<span class="function"><strong>array_replace_recursive()</strong></span> 函数将递归地替换它们各自的值。
