"If you get error messages while starting apache of xampp package with activated extension=intl.dll," do NOT copy any files around.

Use Apache's "LoadFile ..." functionality to load any missing DLL's not found within a %PATH%. Even php##ts.dll itself.

You can use the 'original' abbreviations if you feel more comfortable:

<?php
Normalizer
::NFD;
Normalizer::NFKD;
Normalizer::NFC;
Normalizer::NFKC;
?>

If you get error messages while starting apache of xampp package with activated extension=intl.dll, copy the files

    * icudt##.dll
    * icuin##.dll
    * icuio##.dll
    * icule##.dll
    * iculx##.dll
    * icutu##.dll
    * icuuc##.dll

## = version number

from "/program files/xampp/php"
into your "/program files/xampp/apache/bin" or whereever your xampp resides :-)

Especially when matching texts against each-other or against keywords, it is helpful to normalize the texts before.
The following function removes all diacritics (marks like accents) from a given UTF8-encoded texts and returns ASCii-text.

Be sure to have the PHP-Normalizer-extension (intl and icu) installed.

Tipp: You may also want to map the text to lower case before execute matching procedures ...
