问题
I have a bunch of Danish text taken from a latin-1 MySQL database and it displays correctly when echoed in PHP. The problem starts when I need to echo some other Danish characters, which are not taken from the database.
What I do is actually output the header
Content-Type: text/html; charset=iso-8859-1
to also let the non-queried characters to display correctly as well.
Problems is, when I do that the queried characters display incorrectly.
回答1:
Just because the data is stored in a latin-1 collated table doesn't mean that it's latin-1 encoded. This is due to MySQL not doing any character translation when the connection SET NAMES setting is the same as the collation.
I suspect that you have some UTF8 characters stored in a latin1 database which is confusing the issue.
For more help please can you add details of the:
- MySQL connection encoding that you have set
- Details of where the "non-queried" characters are coming from
回答2:
Use unicode. UTF-8 => the right way.
So, set utf8_unicode_ci in database, UTF-8 as page charset and before your query set mysql_query("SET NAMES UTF8");
