README

This PHP client interacts with the Tika REST Server for extracting content and metadata from a [wide variety of document file types][types]. There are [alternative PHP libraries][alternatives] that use the Tika command line client, but instantiating the JVM for each operation is slow and costly.

This client is built on Guzzle.

"see "Using Tika as a command line utility"" [types]: http://tika.apache.org/1.4/formats.html [alternatives]: https://packagist.org/search/?q=tika

Project Setup

This project is installed with composer.

In the shell, you can run this command:

composer require bangpound/tika-rest-client

Or you can edit your composer.json file to include this requirement:

{
    "require": {
        "bangpound/tika-rest-client": "^1.0"
    }
}

Usage

<?php
$client = new Bangpound\Tika\Client('http://localhost:9998');
$response = $client->tika(array(
    'file' => 'TestPDF.pdf',
));

// Metadata varies by file and file type, so refer to the Apache Tika docs for details.
$all_metadata = $response->metadata;

// If you know the metadata element you want to retrieve, specify it as the argument
// to the response's metadata method.
$author = $response->metadata('author');

// Extracted content can be retrieved as a SimpleXMLElement or a string of XML.
$content_xml = $response->getBody();
$page_2 = $content_xml->children()->div[1];

$content_text = $response->getBody(true);

Testing

The Tika REST Client has an incomplete suite of tests. Run them using phpunit after installing the dev dependencies.

composer install
phpunit
