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"; ?>
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"; ?>
