范例

Example #1 Testing different code points

<?php
var_dump(IntlChar::charType("A") === IntlChar::CHAR_CATEGORY_UPPERCASE_LETTER);
var_dump(IntlChar::charType(".") === IntlChar::CHAR_CATEGORY_OTHER_PUNCTUATION);
var_dump(IntlChar::charType("\t") === IntlChar::CHAR_CATEGORY_CONTROL_CHAR);
var_dump(IntlChar::charType("\u{2603}") === IntlChar::CHAR_CATEGORY_OTHER_SYMBOL);
?>

以上例程会输出：
