How to Detect Language from a String in PHP

If you need to determine the language of a given string in PHP, there are several approaches you can take. One option is to leverage the Text_LanguageDetect PEAR package.

Using Text_LanguageDetect

The Text_LanguageDetect package provides a straightforward method for detecting the language of a UTF-8 encoded string. Here's a brief demonstration of how to use it:

require_once 'Text/LanguageDetect.php';
$l = new Text_LanguageDetect();
$result = $l->detect($text, 4);
if (PEAR::isError($result)) {
    echo $result->getMessage();
} else {
    print_r($result);
}

In this example, $text represents the string you want to analyze, and $result is an array that contains probabilities for each detected language. The "4" argument specifies the maximum number of languages to detect.

The output of the detection process might look something like this:

Array
(
    [german] => 0.407037037037
    [dutch] => 0.288065843621
    [english] => 0.283333333333
    [danish] => 0.234526748971
)

As you can see, the package provides estimates of the language probability distribution for the input string. This can be useful for language identification tasks or for creating multilingual applications.
