php ews connection to Exchange 2010 - php

Question

I downloaded the PHP ews database from https://github.com/jamesiarmes/php-ews.
Autoloader:
function __autoload ($className){
preg_match ("/^(([a-zA-Z]{5})_)?(.+)$/",$className,&$treffer); # die ersten 5 Stellen=Verzeichnisname, Weitere Zeichen=Dateiname
if(file_exists(PROJEKT_DIR.$className.".class.php")) include_once(PROJEKT_DIR.$className.".class.php");
else{
$pfad=SCRIPT_DIR."include/";
if($treffer[2]) $pfad.="classes/".$treffer[2]."/";
if(file_exists($pfad.$treffer[3].".class.php"))
include_once($pfad.$treffer[3].".class.php");
elseif(substr($treffer[3],-7)!="_bvstnd" and class_exists($className."_bvstnd")){
eval("class $className extends ".$className."_bvstnd {} ");
}
else{
// Start from the base path and determine the location from the class name,
$pfad=SCRIPT_DIR."include/php-ews";
$include_file = $pfad . '/' . str_replace('_', '/', $className) . '.php';
return (file_exists($include_file) ? require_once $include_file : false);
}
}
#if(file_exists(SCRIPT_DIR."include/".$className.".class.php"))
# include_once(SCRIPT_DIR."include/".$className.".class.php");
}
it also load some other files.
Then I started doing the Guide from his site, I started doing this:
<?php
$host = "*********";
$username="**********";
$password="***********";
$version= "***********";
$ews = new ExchangeWebServices($host, $username, $password, $version);
$request = new EWSType_FindFolderType();
$request->Traversal = EWSType_FolderQueryTraversalType::SHALLOW;
$request->FolderShape = new EWSType_FolderResponseShapeType();
$request->FolderShape->BaseShape = EWSType_DefaultShapeNamesType::ALL_PROPERTIES;
// configure the view
$request->IndexedPageFolderView = new EWSType_IndexedPageViewType();
$request->IndexedPageFolderView->BasePoint = 'Beginning';
$request->IndexedPageFolderView->Offset = 0;
// set the starting folder as the inbox
$request->ParentFolderIds = new EWSType_NonEmptyArrayOfBaseFolderIdsType();
$request->ParentFolderIds->DistinguishedFolderId = new EWSType_DistinguishedFolderIdType();
$request->ParentFolderIds->DistinguishedFolderId->Id = EWSType_DistinguishedFolderIdNameType::INBOX;
// make the actual call
$response = $ews->FindFolder($request);
?>
At first the Site at the browser just load very long but then tell me something like this: class Exception is undefined. I can't tell the correct message because now this Message doesn´t even show up if I load the script.
The Browser just load infinitely. After this I can't even connect to my server with my PHP files. I have to open my other Browser to connect again.
If I open up the script in my other Browser then I can run the script again but it´s again loading infinity. (I include all my files I need with autoloader so that's not the Problem)
Does anybody have a Problem like that and found a solution?

You have an issue with your autoloader. The default files of that library are loaded like this:
$pfad=SCRIPT_DIR."include/php-ews";
$include_file = $pfad . '/' . str_replace('_', '/', $className) . '.php';
If your autoloader is the first to try and load that exception, it will replace the '_'. If you put an error_log in that autoloader function you will probably see the result of $inlcude_file to be something like
include/php-ews/EWS/Exception
And that file doesn't exist.
So you should fix your autoloader so it can actually find the file.
To be aboslutely clear:
you (the code) are looking for the class EWS_Exception
this is in the file EWS_Exception.php (in the root of the project)
your autoloader cannot find that file as you replace all _
so the sollution is to either fix your autoloader, or just include that EWS_Exception.php file somewhere.
