如何将unicode字符串转换为字符

Question

I want to convert unicode to character.

For this I tried https://stackoverflow.com/a/7278961/4073217 post but it is not working for me.

For Example :

$string = '%u0391%u03b8%u03b1%u03bd%u03b1%u03c3%u03af%u03bf%u03c5';
$string = preg_replace('/%u([0-9A-F]+)/', '&#x$1;', $string);
echo html_entity_decode($string, ENT_COMPAT, 'UTF-8');

Output should be Αθανασίου but above method returning Αb8b1bdb1c3afbfc5.

Am I doing anything wrong? How do I get correct characters from Unicode in php?

Answer 1

the regex:

$string = preg_replace('/%u([0-9A-F]+)/', '&#x$1;', $string) has A-F which means it will only compare capital A-F characters after 0-9. Since you have all small characters match is failing. Try:

$string = preg_replace('/%u([0-9a-f]+)/', '&#x$1;', $string);

instead.

Also check if browser output is utf-8. if not you can use header:

header('Content-type: text/html; charset=utf-8');

before echoing output
