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" ;
?>
以上例程会输出:
not normalized; normalized
