*******************
Text_LanguageDetect
*******************
PHP library to identify human languages from text samples.
Returns confidence scores for each.
Installation
============
PEAR
----
::
$ pear install Text_LanguageDetect
Composer
--------
::
$ composer require pear/text_languagedetect
Usage
=====
Also see the examples in the ``docs/`` directory and
the `official documentation`__.
__ 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";
?>

It then spread south, having an especially significant impact on Rome, which was largely rebuilt by the Renaissance popes. The Italian Renaissance is best known for its cultural achievements. This includes works of literature by such figures as Petrarch, Castiglione, and Machiavelli; artists such as Michaelangelo and Leonardo da Vinci, and great works of architecture such as The Duomo in Florence and St. Peter\'s Basilica in Rome. At the same time, present-day historians also see the era as one of economic regression and of little progress in science.
