  <para>
   <function>array_replace</function> replaces the values of the first
   <parameter>array</parameter> with the same values from all the following
   arrays. If a key from the first array exists in the second array, its value
   will be replaced by the value from the second array. If the key exists in the
   second array, and not the first, it will be created in the first array.
   If a key only exists in the first array, it will be left as is.
   If several arrays are passed for replacement, they will be processed
   in order, the later arrays overwriting the previous values.
  </para>
  <para>
   <function>array_replace</function> is not recursive : it will replace
   values in the first array by whatever type is in the second array.
