Examples
Example #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";
?>
Example #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";
?>
The above example will output:
not normalized; normalized
