b. Open php.in and change mssql.secure_connection = Off to on.

c. Copy php_mssql.dll to the directory specified by extension_dir

in php.in or the system system32 directory. (php_mssql.dll is included in the compressed installation package of php).

After completing the above steps, you need to restart apache.

Note: In actual use, it was found that if you manually install php to iis through a php compressed file, you must restart the machine and not just iis.

Configuration Manager, open the protocolProtocols

b. Allow named pipes "named pipes" and "tcp/ip"

5.FAQ Frequently Asked Questions:

1 Error:

Fatal error: Call to undefined function mssql_connect()

Solution :

Use MSSQL_ series functions

To use these two, you need to set them in php.ini:

(1) To allow DCOM, you need to change php.ini Remove the semicolon ";" before

;com.allow_dcom=TRUE.

(2) To use MSSQL extension, you need to remove the semicolon ";" before

;extension=php_mssql.dll in php.ini. (Key)

(3) Confirm that extension_dir is the correct path. Take this machine as an example: extension_dir = "c:\AppServ\php5\ext".

(4) If the machine still reports an error saying that c:\AppServ\php5\ext\php_mssql.dll cannot be found but this file obviously exists.

Solution: Copy php_mssql.dll and ntwdblib.dll to the system directory \system32 and restart the test. .

(Note: The above two dll files are not in the same directory, mine is c:\AppServ\php5\ext\php_mssql.dll; c:\AppServ\php5\ntwdblib.dll)

Also remember to restart the server after setting it up.

6. Other questions:

If php apache Sql Server2000 is on the same machine, there will be basically no problem accessing it.

If Sql Server2000 and php machines are separated, you need to confirm that the machine name of the machine where sqlserver is located can be pinged. If it cannot be passed, modify the \system32\drivers\etc of the machine where php is located. hosts file, add a line

the machine ip of the machine where sqlserver is located and the machine name of the machine where sqlserver is located.

If you still cannot access it, you need to confirm whether the machine where php is located has a secret conversion to mdac. How about simply installing the sqlserver client.
