前阶段有个项目用到了线上预览功能,
关于预览office文件实现核心就是,把office文件(word,excel,ppt)转为pdf文件,
然后再把pdf文件经过pdf2html转为html文件进行预览。
利用openoffice的话,非常简单,不过效果不太好,转成的pdf样式会乱!
这里就不做介绍了。
下面我把office文件转为pdf步骤写一下(代码在最后):
1.php开启dcom扩展
打开php.ini,搜索php_com_dotnet和php_com_dotnet:
extension=php_com_dotnet.dll //把前面的分号去掉
com.allow_dcom = true //改为true
重启apache
2.配置office组件服务
像这样的操作还有两个!!
3.php代码:
ppt转pdf代码
public function ppt_to_pdf() {
$srcfilename = 'E:/aa.ppt';
$destfilename = 'E:/aa.pdf';
try {
if(!file_exists($srcfilename)){
return;
}
$ppt = new \COM("powerpoint.application") or die("Unable to instantiate Powerpoint");
$presentation = $ppt->Presentations->Open($srcfilename, false, false, false);
$presentation->SaveAs($destfilename,32,1);
$presentation->Close();
$ppt->Quit();
} catch (\Exception $e) {
if (method_exists($ppt, "Quit")){
$ppt->Quit();
}
return;
}
}
excel转ppt
public function excel_to_pdf() {
$srcfilename = 'E:/aa.xls';
$destfilename = 'E:/aa.pdf';
try {
if(!file_exists($srcfilename)){
return;
}
$excel = new \COM("excel.application") or die("Unable to instantiate excel");
$workbook = $excel->Workbooks->Open($srcfilename, null, false, null, "1", "1", true);
$workbook->ExportAsFixedFormat(0, $destfilename);
$workbook->Close();
$excel->Quit();
} catch (\Exception $e) {
echo ("src:$srcfilename catch exception:" . $e->__toString());
if (method_exists($excel, "Quit")){
$excel->Quit();
}
return;
}
}
word转pdf(其实文本格式的文件都可以用这个,比如:txt)
public function doc_to_pdf() {
$srcfilename = 'E:/aa.doc';
$destfilename = 'E:/aa.pdf';
try {
if(!file_exists($srcfilename)){
return;
}
$word = new \COM("word.application") or die("Can't start Word!");
$word->Visible=0;
$word->Documents->Open($srcfilename, false, false, false, "1", "1", true);
$word->ActiveDocument->final = false;
$word->ActiveDocument->Saved = true;
$word->ActiveDocument->ExportAsFixedFormat(
$destfilename,
17, // wdExportFormatPDF
false, // open file after export
0, // wdExportOptimizeForPrint
3, // wdExportFromTo
1, // begin page
5000, // end page
7, // wdExportDocumentWithMarkup
true, // IncludeDocProps
true, // KeepIRM
1 // WdExportCreateBookmarks
);
$word->ActiveDocument->Close();
$word->Quit();
} catch (\Exception $e) {
if (method_exists($word, "Quit")){
$word->Quit();
}
return;
}
}
