PHP IntlChar 函数完整参考

简介

PHP IntlChar 函数库提供了一组用于Unicode字符的操作和属性的函数。

用法

安装

PHP IntlChar 函数库是PHP的标准扩展，所以在PHP安装过程中就已经包含了它。

使用

可以在PHP脚本中使用IntlChar函数库的函数来处理Unicode字符。以下是一些参考用法示例：

// 判断一个字符是否是字母
if (IntlChar::isalpha($char)) {
  // Do something...
}

// 将一个字符转换为小写
$lowercase_char = IntlChar::tolower($char);

// 获取一个字符的名称
$char_name = IntlChar::charName($char);

// 将字符串中的每个字符转换为大写
$uppercase_str = IntlChar::strtoupper($str);
