通过ADO调用Access数据库和COM程序

PHP4已经支持Microsoft的COM技术。然而文档中在COM部分却提得很少。 这儿是几个我试过的例子。希望这些给你一些概念。注意的是这些只能运行在32位的Microsoft Windows平台下。 用php激活ADO ADO是Microsoft的数据库对象技术。ADO里面包括连接数据库的对象,从查询语句中返回数据的记录集对象和表现数据元素的字段对象。 许多数据库不直接支持ADO.代之的是很多数据库支持低两级的Microsoft数据库技术:ODBC和OLEDB.许多数据库支持ODBC;但OLEDB有比ODBC更快的名声。 ADO则是包装ODBC和OLEDB的API. 这个例了打开一个新的ADO连接对象,对过ODBC打开一个传统的ACCESS数据库,然后我们执行SQL查询,会返回一个记录集对象。然后我们显示记录集的前三个字段。 $dbc = new COM("ADODB.Connection"); $dbc->Provider = "MSDASQL"; $dbc->Open("nwind"); $rs = $dbc->Execute("select * from products"); $i = 0; while (!$rs->EOF) { $i += 1; $fld0 = $rs->Fields[0]; $fld1 = $rs->Fields[1]; $fld2 = $rs->Fields[2]; print "$fld0->value $fld1->value $fld2->value
"; $rs->MoveNext(); } $rs->Close(); ?> 用PHP调用Microsoft Word 这是另一个例子: $word=new COM("word.application") or die("Cannot start Microsoft Word"); print "Loaded word version ($word->Version) "; $word->visible = 1 ; $word->Documents->Add(); $word->Selection->Typetext("This is a test"); ?>

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
