    Beispiele

    Beispiel #1 normalizer_is_normalized() example

    <?php
    $char_A_ring     = "\xC3\x85"; // 'LATIN CAPITAL LETTER A WITH RING ABOVE' (U+00C5)
    $char_combining_ring_above = "\xCC\x8A"; // 'COMBINING RING ABOVE' (U+030A)

    $char_orig = 'A' . $char_combining_ring_above;
    $char_norm = normalizer_normalize( 'A' . $char_combining_ring_above, Normalizer::FORM_C );

    echo (     normalizer_is_normalized($char_orig, Normalizer::FORM_C) ) ? "normalized" : "not normalized";
    echo     '; ';
    echo (     normalizer_is_normalized($char_norm, Normalizer::FORM_C) ) ? "normalized" : "not normalized";
    ?>

    Beispiel #2 OO example

    <?php
    $char_A_ring     = "\xC3\x85"; // 'LATIN CAPITAL LETTER A WITH RING ABOVE' (U+00C5)
    $char_combining_ring_above = "\xCC\x8A"; // 'COMBINING RING ABOVE' (U+030A)

    $char_orig = 'A' . $char_combining_ring_above;
    $char_norm = Normalizer::normalize( 'A' . $char_combining_ring_above, Normalizer::FORM_C );

    echo (     Normalizer::isNormalized($char_orig, Normalizer::FORM_C) ) ? "normalized" : "not normalized";
    echo     '; ';
    echo (     Normalizer::isNormalized($char_norm, Normalizer::FORM_C) ) ? "normalized" : "not normalized";
    ?>

    Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

    not normalized; normalized
