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" ;
 ?>
