IntlChar::getBlockCode — Get the Unicode allocation block containing a code point
$codepoint): ?int
Returns the Unicode allocation block that contains the character.
codepoint
The int codepoint value (e.g. 0x2603 for U+2603 SNOWMAN), or the character encoded as a UTF-8 string (e.g. "\u{2603}")
Returns the block value for codepoint.
See the IntlChar::BLOCK_CODE_* constants for possible return values. Returns null on failure.
示例 #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)
