i upgradefrom php version 2.2 to 2.4 and php 5.6 too. The problem is with the new php the function does not support mssql_connect so i installed the new driver for sqlsvr and when i made the Database connection it work fine.
I need some help. How can I change this code from mssql to sqlsvr thanks you and i waiting for your answer.

Answer
Changes, that have to be made, to migrate from MSSQL to SQLSRV extensions of PHP:
Connection:
Functions mssql_connect() and mssql_select_db() must be replaced with sqlsrv_connect():
public function connect() {
$this->db_Host = $this->LSDDBconf['DBSec']['host'];
$this->db_Database = $this->LSDDBconf['DBSec']['dbname'];
$this->db_Password = $this->LSDDBconf['DBSec']['pwd'];
$this->db_User = $this->LSDDBconf['DBSec']['user'];
if ( 0 == $this->db_Link ) {
$this->db_Link = sqlsrv_connect($this->db_Host, array("Database"=>$this->db_Database, "UID"=>$this->db_User, "PWD"=>$this->db_Password));
if ($this->db_Link === false) {
$Err->SendAdminInfo("mail_db");
die("<br><br><b><font color="red">Invalid SQL connect-DB</font></b>");
exit;
}
}
}
Query:
public function query($Query_String) {
$this->connect();
# SQLSRV_CURSOR_FORWARD - Lets you move one row at a time starting at the first row of the result set until you reach the end of the result set.
# This is the default cursor type. sqlsrv_num_rows returns an error for result sets created with this cursor type.
# SQLSRV_CURSOR_STATIC - Lets you access rows in any order but will not reflect changes in the database.
# SQLSRV_CURSOR_DYNAMIC - Lets you access rows in any order and will reflect changes in the database.
# sqlsrv_num_rows returns an error for result sets created with this cursor type.
# SQLSRV_CURSOR_KEYSET - Lets you access rows in any order. However, a keyset cursor does not update the row count if a row is deleted from the
# table (a deleted row is returned with no values).
# SQLSRV_CURSOR_CLIENT_BUFFERED - Lets you access rows in any order. Creates a client-side cursor query.
$this->db_Query = sqlsrv_query($this->db_Link, $Query_String, array(), array("Scrollable" => SQLSRV_CURSOR_KEYSET));
$this->db_Row = 0;
if (!$this->db_Query) {
die("<br><br><b><font color="red">Invalid SQL Query</font></b>");
}
return $this->db_Query;
}
Fetch record:
public function next_record() {
# SQLSRV_FETCH_ASSOC - sqlsrv_fetch_array returns the next row of data as anassociative array.
# SQLSRV_FETCH_BOTH - sqlsrv_fetch_array returns the next row of data as an array with both numeric and associative keys. This is the default value.
# SQLSRV_FETCH_NUMERIC - sqlsrv_fetch_array returns the next row of data as a numerically indexed array
$this->db_Record = sqlsrv_fetch_array($this->db_Query, SQLSRV_FETCH_BOTH);
$this->db_Row += 1;
return $this->db_Record;
}
Row count:
public function num_rows(){
# sqlsrv_num_rows requires a client-side, static, or keyset cursor, and will return false if you use a forward cursor or
# a dynamic cursor. (A forward cursor is the default.) For more information about cursors, see sqlsrv_query and Cursor Types (SQLSRV Driver).
$this->db_numRows = sqlsrv_num_rows($this->db_Query);
return $this->db_numRows;
}
public function rows_affected(){
$this->db_Query = sqlsrv_query($this->db_Link, "SELECT @@ROWCOUNT");
$this->db_numRows = sqlsrv_fetch_array($this->db_Query, SQLSRV_FETCH_NUMERIC);
return $this->db_numRows[0];
}
