      Every parameter to <function>preg_replace</function> (except
-     <parameter>limit</parameter>) can be an array.  When using arrays with
-     <parameter>pattern</parameter> and <parameter>replacement</parameter>,
-     the keys are processed in the order they appear in the array.  This is
-     <emphasis>not necessarily</emphasis> the same as the numerical index
-     order.  If you use indexes to identify which
-     <parameter>pattern</parameter> should be replaced by which
+     <parameter>limit</parameter>) can be an unidimensional array.
