示例

示例 #1 normalizer_normalize() 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_1 = normalizer_normalize( $char_A_ring, Normalizer::FORM_C );
$char_2 = normalizer_normalize( 'A' . $char_combining_ring_above, Normalizer::FORM_C );

echo urlencode($char_1);
echo ' ';
echo urlencode($char_2);
?>

示例 #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_1 = Normalizer::normalize( $char_A_ring, Normalizer::FORM_C );
$char_2 = Normalizer::normalize( 'A' . $char_combining_ring_above, Normalizer::FORM_C );

echo urlencode($char_1);
echo ' ';
echo urlencode($char_2);
?>

以上示例会输出：

%C3%85 %C3%85
