じゃあ PHP は?

<?php
    $a = '0123abcd0123';
    if(preg_match('/(\p{IsAlpha}+)/', $a, $match)) {
        var_dump($match);
    } else {
        echo "not match\n";
    }
?>


[fetus@RIM ~]$ php hoge.php
PHP Warning: preg_match(): Compilation failed: unknown property name after \P or \p at offset 11 in /home/fetus/hoge.php on line 3
not match

……あっそう。

<?php
    $a = '0123abcd0123';
    if(preg_match('/([[:alpha:]]+)/', $a, $match)) {
        var_dump($match);
    } else {
        echo "not match\n";
    }
?>


[fetus@RIM ~]$ php hoge.php
array(2) {
  [0]=>
  string(4) "abcd"
  [1]=>
  string(4) "abcd"
}

…全然「Perl 互換」ちゃうやん

# 調べてみたら、\p と \P は全然違う用途に使う模様。PCRE さーん、Incompatible なんですけどー。 Perl 側でも POSIX の文字クラスは使えるからそっち側で書けば…か。

という記事を書くと、「環境書けやゴルァ」というのが目に見えているので書いておく。
