我有以下字符串:
$string = "★ This is some text ★";
我想将其转换为html实体:
$string = "★ This is some text ★";
每个人都在写的解决方案:
htmlentities("★ This is some text ★", "UTF-8");
但是,htmlentities不能将所有unicode转换为html实体。所以它只给了我与输入相同的输出:
★ This is some text ★
我也尝试将此解决方案与两者结合使用:
header('Content-Type: text/plain; charset=utf-8');
和
mb_convert_encoding();
但这会打印并清空结果,根本不会转换或错误地将星号转换为:

如何将★和所有其他unicode字符转换为正确的html实体?
答案 0 :(得分:5)
htmlentities
在这种情况下无法工作,但您可以尝试UCS-4
对字符串进行编码,例如:
$string = "★ This is some text ★";
$entity = preg_replace_callback('/[\x{80}-\x{10FFFF}]/u', function ($m) {
$char = current($m);
$utf = iconv('UTF-8', 'UCS-4', $char);
return sprintf("&#x%s;", ltrim(strtoupper(bin2hex($utf)), "0"));
}, $string);
echo $entity;
★ This is some text ★
