The following is a public ODBC manipulation class that I have used in the SQL Server2000 in a PHP, I hope to give you a little bit of helping to begin PHP.
File: // Name and password are standard.
Define (c_db_host, $ host); define (c_db_name, $ dbname); define (c_db_user, $ dbuse); define (c_db_pass, $ dbpassword);
class Odbc {var $ Host = C_DB_HOST; // Hostname of our MySQL server var $ Database = C_DB_NAME; // Logical database name on that server var $ User = C_DB_USER; // Database user var $ Password = C_DB_PASS; // Database user's Password var $ useodbccursor = 0;
Var $ link_id = 0; // result of mysql_connect () var $ query_id = 0; // Result of most required mysql_Query () // var $ record = array (); // current mysql_fetch_array () - Result var $ row = 0; // Current Row Number Var $ Errno = 0; // Error State of Query Var $ Error = ""
Var $ auto_free = 0; ## set this to 1 to Automatically Free Results

My operation class is an ODBC interface class. The ODBC connection is first required before calling the data operation, and then pays the corresponding value to the following variables for manipulation:
$ Dbname = "localhost"; $ dbuser = "sa"; $ dbpassword = ""; ///
Assuming that the table Table1 in the database is performed as follows when the ODBC connection is successful.
$ db = new odbc ();
$ SQ1 = "Select * from $ TABLE"; // Select all records in the table
$ dB-> query ($ SQL);
While ($ result = $ db-> nextrecrod)
{
Echo $ Result;
}
$ dB-> close ();
