问题
There are the problems of data in mysql.
Some data store with the string like (1):"hello & hello ' hello è ...". And some data store with the string like (2):"hello à hello é hello ê ...".
I can solve the string (1) to the normal string, but I don't know how to convert the string (2) to the normal string?
Note : We can not change the data in the existing database :/ Also the both sample is store in the same table and the charset of the table is latin1!
回答1:
hello à hello é hello ê probably is UTF-8 interpreted as ISO-8859-1.
You can either change the interpretation, e.g. in a browser set a charset, or convert it to ISO-8859-1 using utf8_decode().

EDIT-
Without changing the DB structure try this --
ini_set('default_charset', 'YOUR_CHARACTER_SET')
OR try this --
header('Content-Type: text/html; charset=iso-8859-1');
Check this setting, its all bcoz of table collation

Use CONVERT as CONVERT ("hello à hello é hello ê ...", ascii) ....
