如何使用PHP在MS Word文档中搜索和替换文本片段

Main goal: create documents (with tables) in Microsoft Word using PHP.

Critical problem encountered: calling:

$document->Range->Find->Execute( ... );  // causes ERROR.

I get information about: line, File, Source: unknown, Description: unknown;

How do I do it (operations in Microsoft Word using PHP):

• I open a document template from a file (success)
• I insert plain text into the document using

    ->Range->InsertAfter(  "whatever text needed to be inserted" ); // (success)

• I define a new Range object:

    $range = $document->Range( x, y );

• and convert the Range into a Table (success)

    $Table1 = $range->ConverToTable( wdSeparateByTabs, 1, 2, 30, wdTableFormatNone, false, false, false, false, false, false, false, false, false, wdAutoFitWindow, wdWord9ListBehavior );
//  with
    wdSeparateByTabs = 1
    wdTableFormatNone = 0
    wdAutoFitWindow = 2
    wdWord9ListBehavior = 1

• Despite the fact that i pass number_of_rows=1 (2nd parameter), the table looks as expected.

• Next step I want, is to make Word find and replace strings:

$rng = $Table1->Range;
$find = $rng->Find;
$find->Execute( "text to find", false, false, false, false, false, null, wdFindContinue, false, "text to be replaced with", wdReplaceAll, null, null, null, null );

Some system info:

• all on a virtual machine Oracle VM VirtualBox 5.2.0
• Windows XP sp3
• Apache 2.2.6
• PHP 5.2.9
• Microsoft Office Word 2002 (10.2627)

Final thoughts and ideas:

• when I comment out the ->Find->Execute( ... ) section - all is done as expected
• I create a table from a plain text with cells separated by a character (tab in my example) thus I can't create a cell with multiple lines (\x0A) this way because Word uses \x0A as a separator too (tested);
• I need to have cells with multiple lines (separated by \x0A or \x0B)
• the idea was to insert a plain text with html's < br > line separator, convert it to a table, and replace '< br >' with \x0A or \x0B when the table is created
• I'm positive that I can achieve needed goal different way (ways)
• I've done a very similar test using C# in VisualStudioExpress2010, but all works as expected, I don't get an ERROR as I do using PHP

What do I do wrong that calling

->Range->Find->Execute(...);

causes an error?

EDIT: I don't use frameworks, just plan Word, and stock PHP

$word = new COM( 'Word.Application' );
$document = $word->Documents->Add( ); //or
$document = $word->Documents->Open( 'template_file.doc' );
