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.

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.
