Unicode data in a unicode-only collation or ntext data cannot is sent to clients using db-library (such as ISQL) or ODBC V Ersion 3.7 or earlier

When PHP is connected to SQL Server, the program generates a statement that, when executed by the SQL Server client, can correctly return the results, execute in the program, always return false, and open debugging without any errors. Inadvertently found the error shown in title, the following methods:

• Chang the version in from/etc/freetds.conf4.2 to 8.0 (if the PHP server is *nix)
• Client CharSet = GBK

PHP.ini Configuration

Mssql.charset = "UTF-8"
