Installation
============

PEAR

Usage
=====
Also see the examples in the ``docs/`` directory and

__ http://pear.php.net/package/Text_LanguageDetect/docs

Language detection
------------------
Simple language detection::

    <?php
    require_once 'Text/LanguageDetect.php';

    $text = 'Was wäre, wenn ich Ihnen das jetzt sagen würde?';

    $ld = new Text_LanguageDetect();
    $language = $ld->detectSimple($text);

    echo $language;
    //output: german

Show the three most probable languages with their confidence score::

    <?php
    require_once 'Text/LanguageDetect.php';

    $text = 'Was wäre, wenn ich Ihnen das jetzt sagen würde?';

    $ld = new Text_LanguageDetect();
    //3 most probable languages
    $results = $ld->detect($text, 3);

    foreach ($results as $language => $confidence) {
        echo $language . ': ' . number_format($confidence, 2) . "\n";
    }

    //output:
    //german: 0.35
    //dutch: 0.25
    //swedish: 0.20
    ?>


Language code
-------------
Instead of returning the full language name, ISO 639-2 two and three
letter codes can be returned::

    <?php
    require_once 'Text/LanguageDetect.php';
    $ld = new Text_LanguageDetect();

    //will output the ISO 639-1 two-letter language code
    // "de"
    $ld->setNameMode(2);
    echo $ld->detectSimple('Das ist ein kleiner Text') . "\n";

    //will output the ISO 639-2 three-letter language code
    // "deu"
    $ld->setNameMode(3);
    echo $ld->detectSimple('Das ist ein kleiner Text') . "\n";
    ?>
