Listing 2: retrieveOracleData.php

<?php

$username='OE';
$password='pw';

$db='(DESCRIPTION =
  (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
   (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = ORCL)
   )
)';

$connection = oci_connect($username, $password, $db);
$stmt = oci_parse($connection, "SELECT * from OE.CATALOG
   WHERE JOURNAL=:journal");

$journal='Oracle Magazine';
oci_bind_by_name($stmt, ":journal", $journal);

$r = oci_execute($stmt);

$nrows = oci_fetch_all($stmt, $results);

if($nrows>0){
echo "<table border><tr><th>Catalog

Id</th><th>Journal</th><th>Publisher</th><th>Edition</th>
   <th>Title</th><th>Author</th></tr>";

for ($i = 0; $i < $nrows; $i++) {
   echo "<tr>\n";
   foreach ($results as $data) {
      echo "<td>$data[$i]</td>\n";
   }
   echo "</tr>\n";
}

echo "</table>";

}

?>

Next, run the retrieveOracleData.php script in the Apache web server with the URL http://localhost/retrieveOracleData.php. The Oracle database data gets retrieved and displayed in an HTML table, as shown in Figure 2.

Conclusion

PHP provides the OCI8 extension to connect to an Oracle database and runs SQL queries in the database. In this article, you installed the OCI8 extension, established a connection to Oracle database, created a database table, and retrieved database table data.
