html_entity_decode无法正常工作[重复]

• UTF-8 all the way through 15 answers

I am moving a PHP application to another server, and I have some issues with the character decoding:

Old server (CentOS with Plesk Panel):

echo htmlentities('ú'), ENT_QUOTES, 'UTF-8'); // Result ú
echo html_entity_decode('&uacute', ENT_QUOTES, 'UTF-8'); // Result ú <= expected

New server (Debian dedicated server, fresh install):

echo htmlentities('ú'), ENT_QUOTES, 'UTF-8'); // Result ú    
echo html_entity_decode('&uacute', ENT_QUOTES, 'UTF-8'); // Result ú <= not expected
echo html_entity_decode('&uacute', ENT_QUOTES, 'ISO-8859-1'); // Result ú <= expected

Why is happening this? Maybe a server configuration problem?

Try following

echo htmlentities('ú', ENT_QUOTES, 'UTF-8');
echo html_entity_decode('ú', ENT_QUOTES, 'ISO-8859-1');
