connect microsoft access database using php script

Today we learn how to connect using microsoft access database using php script.Just follow this simple step. Step One :

---

Create database in microsoft access and add data to related tables.  

Step Two: configure database to ODBC

---

Here is how to create an ODBC connection to a MS Access Database:

1. Open the Administrative Tools icon in your Control Panel.
2. Double-click on the Data Sources (ODBC) icon inside.
3. Choose the System DSN tab.
4. Click on Add in the System DSN tab.
5. Select the Microsoft Access Driver. Click Finish.
6. In the next screen, click Select to locate the database.
7. Give the database a Data Source Name (DSN).
8. Click OK.

Note that this configuration has to be done on the computer where your web site is located. If you are running Internet Information Server (IIS) on your own computer, the instructions above will work, but if your web site is located on a remote server, you have to have physical access to that server, or ask your web host to to set up a DSN for you to use.

 Step Three : Connecting to an ODBC

---

The odbc_connect() function is used to connect to an ODBC data source. The function takes four parameters: the data source name, username, password, and an optional cursor type.The odbc_exec() function is used to execute an SQL statement.  

Step Four : Retrieving Records

The odbc_fetch_row() function is used to return records from the result-set. This function returns true if it is able to return rows, otherwise false.

---

The odbc_result() function is used to read fields from a record. This function takes two parameters: the ODBC result identifier and a field number or name.  
The code line below returns the value of the first field from the record: $compname=odbc_result($rs,1); The code line below returns the value of a field called "CompanyName": $compname=odbc_result($rs,"CompanyName");  
Step Six : Closing an ODBC Connection

---

The odbc_close() function is used to close an ODBC connection.

---

Example :
[php]
$conn=odbc_connect('northwind','','');
if (!$conn)
  {exit("Connection Failed: " . $conn);}
$sql="SELECT * FROM customers";
$rs=odbc_exec($conn,$sql);
if (!$rs)
  {exit("Error in SQL");}
echo "<table><tr>";
echo "<th>Companyname</th>";
echo "<th>Contactname</th></tr>";
while (odbc_fetch_row($rs))
  {
  $compname=odbc_result($rs,"CompanyName");
  $conname=odbc_result($rs,"ContactName");
  echo "<tr><td>$compname</td>";
  echo "<td>$conname</td></tr>";
  }
odbc_close($conn);
echo "</table>";
