Japanese Field Pattern

To extract hiragana, katakana, kanji portion of a Japanese text, explicity set the unicode range AND specify u modifier for the pattern.

<?php 
 
echo "Hiragana -- "; 
$pattern ='/[^\x{3040}-\x{309F}]+/u'; 
$s=preg_replace($pattern,"",$str); 
echo $s."<br />"; 
 
echo "Katakana -- "; 
$pattern ='/[^\x{30A0}-\x{30FF}]+/u'; 
$s=preg_replace($pattern,"",$str); 
echo $s."<br />"; 
 
echo "Kanji -- "; 
$pattern ='/[^\x{4E00}-\x{9FBF}]+/u'; 
$s=preg_replace($pattern,"",$str); 
echo $s."<br />"; 
 
?>
