For Each


Starting with PHP 5, 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.

Пример #1 For Each in ASP

<% Set domainObject = GetObject("WinNT://Domain") For Each obj in domainObject   Response.Write obj.Name & "<br />" Next %>

Пример #2 while() ... Next() in PHP 4

<?php 
$domainObject 
= new COM("WinNT://Domain"); 
while (
$obj $domainObject->Next()) { 
   echo 
$obj->Name "<br />"

?>

Пример #3 foreach in PHP 5

<?php 
$domainObject 
= new COM("WinNT://Domain"); 
foreach (
$domainObject as $obj) { 
   echo 
$obj->Name "<br />"

?>
