com_load_typelib

(PHP 4 >= 4.1.0, PHP 5, PHP 7, PHP 8)

com_load_typelib — 载入 Typelib

说明

com_load_typelib(string $typelib, bool $case_insensitive = true): bool

载入类型库并在引擎中注册它们的常量，就像使用 define() 定义一样。

注意，使用 com.typelib-file php.ini 配置设置来预载入和注册常量会更加有效，尽管不是那么灵活。

如果开启 com.autoregister-typelib，然后 PHP 将在实例化 COM 对象时尝试自动注册与其相关的常量。这取决于 COM 对象本身提供的接口并且不总是可用。

参数

typelib

typelib 可以是以下其中一个：

.tlb 文件或者包含类型库的可执行模块的文件名。
类型库 GUID，后跟版本号，例如 {00000200-0000-0010-8000-00AA006D2EA4},2,0。
类型库名称，例如 Microsoft OLE DB ActiveX Data Objects 1.0 Library。

PHP 将会尝试按照此顺序解析类型库，随着该列表的推进，该过程变得越来越昂贵；通过物理枚举注册表来按名称搜索类型库，直到找到匹配项。

case_insensitive

case_insensitive 的行为正好与 define() 中的 $case_insensitive 参数相反。

返回值

成功时返回 true，或者在失败时返回 false。

I had some problems with a third-party Word-controlling code that is somewhat similar to Richard's example. (Word 2007 SP1, XP SP2.) Rewrote some parts according to that example, no luck. Error messages from Word were crazy:

"Bad parameter" -- it didn't like wdGoToBookmark but was ok with its numeric equivalent -1;

"Call to undefined method variant::SaveAs()" -- the same with Save() that was suitable in my case, so no options were remaining.

But then I ran the example via php.exe in the command line, and it worked! Eventually it turned out that Apache service must be run as some real user instead of SYSTEM.

Some libraries load other libraries as part of their functionality. For example Crystal Reports Object Factory uses the CreateObject() method to create an instance of a Crystal Design RunTime Application. If you want to use constants defined in the newly loaded library, you will need to manually register the library - even with com.autoregister_typelib set to true.



<?php

echo 'com.autoregister_typelib = ', ini_get('com.autoregister_typelib'), PHP_EOL;



$o_CrObjectFactory = New COM('CrystalReports11.ObjectFactory.1');



$o_CrApplication = $o_CrObjectFactory->CreateObject("CrystalDesignRunTime.Application");



echo 'Will not be defined : ', crOpenReportByDefault, PHP_EOL;



com_load_typelib('CrystalDesignRunTime.Application');



echo 'Will now be defined : ', crOpenReportByDefault, PHP_EOL;

?>



outputs ...



com.autoregister_typelib = 1

Will not be defined :

Notice: Use of undefined constant crOpenReportByDefault - assumed 'crOpenReportByDefault' in C:\refl.php on line 8

crOpenReportByDefault

Will now be defined : 0

In case any of you were wondering what com_load_typelib actually DOES, I have found that it loads constants\enums that the COM obeject has defined.  The example below is using the Nero COM object (from Nero Burning rom, version 6+).  The Nero object defines a bunch of constants, but they can not be used as PHP constants unless you use the mentioned function.  So the example below will work just fine:

<?php
$aNero = new COM("Nero.Nero") or die ("Nero didn't load, too bad");
com_load_typelib("Nero.Nero");
$aNero->GetDrives(NERO_MEDIA_CD);
?>

But this one will not, since PHP will return a message saying that the constant is undefined:

<?php
$aNero = new COM("Nero.Nero") or die ("Nero didn't load, too bad");
$aNero->GetDrives(NERO_MEDIA_CD);
?>

This one took me a while to figure out, hope it helps.

Hello PHP community, I want to help in a problem I found in this COM built-in function: com_load_typelib(), when I executed it in order to open a COM Server process (for example: Word, Excel, etc.) I was in trouble to release the object from memory, I figured it out, this is the solution:

Change a configuration in the php.ini:

; autoregister constants of a components typlib on com_load()
com.autoregister_typelib = true

When com.autoregister_typelib directive is true, PHP parser manage the COM server type library, I hope it helps.

<?php
// Some servers may have an auto timeout, so take as long as you want.
set_time_limit(0);

// Show all errors, warnings and notices whilst developing.
error_reporting(E_ALL);

// Used as a placeholder in certain COM functions where no parameter is required.
$empty = new VARIANT();

// Load the appropriate type library.
com_load_typelib('Word.Application');

// Create an object to use.
$word = new COM('word.application') or die('Unable to load Word');
print "Loaded Word, version {$word->Version}\n";

// Open a new document with bookmarks of YourName and YourAge.
$word->Documents->Open('C:/Unfilled.DOC');

// Fill in the information from the form.
$word->Selection->GoTo(wdGoToBookmark,$empty,$empty,'YourName'); // Note use of wdGoToBookmark, from the typelibrary and the use of $empty.
$word->Selection->TypeText($_GET['YourName']);

$word->Selection->GoTo(wdGoToBookmark,$empty,$empty,'YourAge');
$word->Selection->TypeText($_GET['YourAge']);

// Save it, close word and finish.
$word->Documents[1]->SaveAs("C:/{$_GET['YourName']}.doc");
$word->Quit();
$word->Release();
$word = null;
print "Word closed.\n";
?>

The example document is ...

Hello [Bookmark of YourName], you are [Bookmark of YourAge] years old.

and it would be called ...

word.php?YourName=Richard%20Quadling&YourAge=35

Regards,

Richard.
