我有以下字符串:
$string = "★ This is some text ★";
我想把它转换成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。所以它只是给了我与输入相同的输出:
★ This is some text ★
我还尝试将这个解决方案与两者结合起来:
header('Content-Type: text/plain; charset=utf-8');
和:
mb_convert_encoding();
但这要么打印并清空结果,根本无法转换,要么错误地将恒星转换为:

如何转换★以及所有其他unicode字符到正确的html实体?
htmlentities
在这种情况下不起作用,但您可以尝试UCS-4
对字符串进行编码,类似于:
$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 ★

这是更好的
html_entity_decode('zł');
输出-zł
