How to achieve php online demonstration function?

Realization of php online Preview function under Windows

Recently used the document online preview function, did not touch before, everything starts from scratch, the whole period of time finally realized, now the method to share with you!

I. main train of thought

First of all, other formats of documents (office documents, txt, pictures, etc.) are converted into PDF format documents through OpenOffice, then PDF format documents are converted into swf format documents through swftools (http://www.swftools.org/), and finally swf format documents are displayed through flexpaper, thus realizing the preview of documents in a variety of formats.

The tools used are downloaded from the Internet and are easy to find.

Second, the process of realization

1. Other documents are converted to PDF

Start OpenOffice with the command:

Run-> cmd, and enter the following command

Cd / d E:/openoffice/program & soffice-headless-accept= "socket,host=127.0.0.1,port=8100;urp;"-nofirststartwizard

Or enter the program directory in cmd and type

Soffice-headless-accept= "socket,host=127.0.0.1,port=8100;urp;"-nofirststartwizard

Php implementation code:

Set_time_limit (0); function MakePropertyValue ($name,$value,$osm) {$oStruct = $osm- > Bridge_GetStruct ("com.sun.star.beans.PropertyValue"); $oStruct- > Name = $name; $oStruct- > Value = $value Return $oStruct;} function word2pdf ($doc_url, $output_url) {$osm = new COM ("com.sun.star.ServiceManager") or die ("Please be sure that OpenOffice.org is installed.n") $args = array (MakePropertyValue ("Hidden", true,$osm)); $oDesktop = $osm- > createInstance ("com.sun.star.frame.Desktop"); $oWriterDoc = $oDesktop- > loadComponentFromURL ($doc_url, "_ blank", 0, $args) $export_args = array (MakePropertyValue ("FilterName", "writer_pdf_Export", $osm)); $oWriterDoc- > storeToURL ($output_url,$export_args); $oWriterDoc- > close (true) } $doc_file = 'DMAG WAMP doc_file www doc_file file:///"; $DGV =' DGV 'onlineread Grey Universe docfile.docked; $DGV =' DMAX onlinereadCharger WAMP * * $doc_file; $output_file = "file:///". $output_file; word2pdf ($doc_file,$output_file)

2.PDF is converted to swf and displays

Php implementation code:

Var path= "/"; / / call the variable of php. If it cannot be implemented, consider writing / / var path= "/" in the next sentence. Var fp = new FlexPaperViewer ('_ _ PUBLIC__/FlexPaper/FlexPaperFlash/FlexPaperViewer', 'viewerPlaceHolder', {config: {/ / configuration parameters You can modify it to the desired SwfFile: escape (path), Scale: 1, ZoomTransition: 'easeOut', ZoomTime: 0.5, ZoomInterval: 0.2, FitPageOnLoad: false FitWidthOnLoad: false, PrintEnabled: true, FullScreenAsMaxWindow: false, ProgressiveLoading: false, MinZoomSize: 0.2, MaxZoomSize: 5, SearchMatchAll: false InitViewMode: 'Portrait', ViewModeToolsVisible: true, ZoomToolsVisible: true, NavToolsVisible: true, CursorToolsVisible: true, SearchToolsVisible: true LocaleChain: 'en_US'}})

3. Preparation before operation

You need to make the following settings first, otherwise there may be errors in the process of running!

Control Panel-Administrative tools-component Services-computer-my computer-DOCM configuration, find the OpenOffice Service Manager (Ver 1.0) right-click properties, and configure as shown in the following figure:

Find OpenOffice Service Manager (Ver 1.0) as shown in the following figure:

Select Security in the pop-up box and edit Startup and Activation permissions and access permissions respectively:

Click add in the 'launch and activate permissions' pop-up box and enter Everyone:

Set the permissions for Everyone:

Click add in the pop-up box of 'access permissions' and enter Everyone:

Set Everyone permissions:

Select 'identity' in the properties dialog box and select 'Interactive user':

If you encounter a failure to instantiate the COM class, open the php configuration file, remove the semicolon before com.allow_dcom=true, and add extension=php_com_dotnet.dll, because php5.4 will not embed com later.

Don't forget to restart the service after setting up!
