+     In our example above you see the <literal>"a" =&gt; "green"</literal>
+     pair is present in both arrays and thus it is not in the ouput from the
+     function. Unlike this, the pair <literal>0 =&gt; "red"</literal> 
+     is in the ouput because in the second argument <literal>"red"</literal>
+     has key which is <literal>1</literal>. 
+    </simpara>
+    <simpara>
+     Two values from <emphasis>key =&gt; value</emphasis> pairs are
+     considered equal only if <literal>(string) $elem1 === (string)
+     $elem2 </literal>. In other words a strict check takes place so 
+     the string representations must be the same.

+    <note>
+     <simpara>
+      Please note that this function only checks one dimension of a n-dimensional
+      array. Of course you can check deeper dimensions by using, for example, 
+      <literal>array_diff_assoc($array1[0], $array2[0]);</literal>.
