IntlChar::getBlockCode — Get the Unicode allocation block containing a code point
Returns the Unicode allocation block that contains the character.
Returns the block value for codepoint.
See the IntlChar::BLOCK_CODE_* constants for possible return values.
Example #1 Testing different code points
<?php
var_dump(IntlChar::getBlockCode("A") === IntlChar::BLOCK_CODE_BASIC_LATIN);
var_dump(IntlChar::getBlockCode("Φ") === IntlChar::BLOCK_CODE_GREEK);
var_dump(IntlChar::getBlockCode("\u{2603}") === IntlChar::BLOCK_CODE_MISCELLANEOUS_SYMBOLS);
?>
以上例程会输出：
bool(true) bool(true) bool(true)
