Virtual library

Content analysis of several document formats with phpdocx Indexer

Virtual library content analysis

A virtual library contains documents in different formats (TXT, DOC, RTF, ODT and DOCX), and wants to analyze their contents. To accomplish this task, they use the conversion plugin of phpdocx to convert them to DOCX and later analyze the content with Indexer.

The formats of the documents are transformed with the method transformDocument of the conversion plugin. The following code snippet shows an example of each format.

$docx = new CreateDocx();

// DOC
$docx->transformDocument('docDocument.doc', 'docDocument.docx');

// RTF
$docx->transformDocument('rtfDocument.rtf', 'rtfDocument.docx');

// ODT
$docx->transformDocument('odtDocument.odt', 'odtDocument.docx');

// TXT
$docx->transformDocument('docDocument.txt', 'docDocument.docx');

Using Indexer, the contents of the documents can be analyzed, for example extracting text and image contents:

$indexerDoc = new Indexer('docDocument.docx');

$outputDoc = $indexerDoc->getOutput();
$textDoc = array();
$textDoc[] =
    array(
        'text' => 'docDocument.docx: ',
        'bold' => true,
    );
$textDoc[] =
    array(
        'text' => $output['body']['text'],
        'images' => $output['body']['images']
    );
