<title>For Each</title>
<para>
You may use PHP's own
&foreach; statement to iterate
over the contents of a standard COM/OLE IEnumVariant. In layman's terms,
this means that you can use foreach in places where you would have used
<literal>For Each</literal> in VB/ASP code.
</para>
<para>
<example>
<title>For Each in ASP</title>
<programlisting role="asp">
<![CDATA[
<%
Set domainObject = GetObject("WinNT://Domain")
For Each obj in domainObject
Response.Write obj.Name & "<br />"
Next
%>
]]>
</programlisting>
</example>
</para>
<para>
<example>
<title>foreach in PHP</title>
<programlisting role="php">
<![CDATA[
<?php
$domainObject = new COM("WinNT://Domain");
foreach ($domainObject as $obj) {
echo $obj->Name . "<br />";
}
?>
]]>
</programlisting>

<section xml:id="com.examples.arrays">
<title>Arrays and Array-style COM properties</title>
<para>
Many COM objects expose their properties as arrays, or using array-style
access.
</para>
<para>
You can:
<itemizedlist>
<listitem>
<para>
Access multi-dimensional arrays, or COM properties that require
multiple parameters using PHP array syntax. You can also write or set
properties using this technique.
</para>
</listitem>
<listitem>
<para>
Iterate SafeArrays ("true" arrays) using the &foreach; control structure.
This works because SafeArrays include information about their size. If an
array-style property implements IEnumVariant then you can also use
foreach for that property too; take a look at <xref
linkend="com.examples.foreach"/> for more information on this topic.
