<para>
|
|
<function>array_replace_recursive</function> 使用后面数组元素的值替换数组 <parameter>array</parameter> 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。
|
|
</para>
|
|
<para>
|
|
<function>array_replace_recursive</function> 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。
|
|
</para>
|
|
<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,
|
|
<function>array_replace_recursive</function> 函数将递归地替换它们各自的值。
