For Each
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
For Each in VB/ASP code.
示例 #1 For Each in ASP
<%
Set domainObject = GetObject("WinNT://Domain")
For Each obj in domainObject
Response.Write obj.Name & "<br />"
Next
%>
示例 #2 foreach in PHP
<?php
$domainObject = new COM("WinNT://Domain");
foreach ($domainObject as $obj) {
echo $obj->Name . "<br />";
}
?>
