Text Language Detect

Detects the language of a given piece of text.

The package attempts to detect the language of a sample of text by correlating ranked 3-gram frequencies to a table of 3-gram frequencies of known languages.

It implements a version of a technique originally proposed by Cavnar & Trenkle (1994): "N-Gram-Based Text Categorization".

This is a fork of Text_LanguageDetect 0.3.0 (alpha).

Dependencies:

PHP Version: PHP 5.3 or newer
PHP Extension: pcre
PHP Extension: mbstring (optional)

Usage example

<?php

use TextLanguageDetect\TextLanguageDetect;
use TextLanguageDetect\LanguageDetect\TextLanguageDetectException;

$l = new TextLanguageDetect();

echo "Supported languages:\n";
try {
    $langs = $l->getLanguages();
    sort($langs);
    echo implode(', ', $langs) . "\n\n";
} catch (TextLanguageDetectException $e) {
    die($e->getMessage());
}

$text = <<<EOD
Hallo! Das ist ein Text in deutscher Sprache.
Mal sehen, ob die Klasse erkennt, welche Sprache das hier ist.
EOD;

try {
    //return 2-letter language codes only
    $l->setNameMode(2);

    $result = $l->detect($text, 4);
    print_r($result);
} catch (TextLanguageDetectException $e) {
    die($e->getMessage());
}
