PHP中的Oracle连接错误。 致命错误：调用未定义函数oci_connect（）

Question

I am working on this project where i need to connect to the Oracle database. I am using the latest version of WAMP 2.2 and also activated all the extensions related the Oracle in PHP extensions. I have used following code for the connection to Oracle Database.

<?php 

$dbHost = "192.168.0.205";
$dbHostPort="1523";
$dbServiceName = "orcl";
$usr = "system";
$pswd = "admin";
$dbConnStr = "(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)
        (HOST=".$dbHost.")(PORT=".$dbHostPort."))
        (CONNECT_DATA=(SERVICE_NAME=".$dbServiceName.")))";

if(!$dbConn = oci_connect($usr,$pswd,'192.168.0.205:1158/em')){
$err = oci_error();
trigger_error('Could not establish a connection: ' . $err['message'], E_USER_ERROR);
}
else
{
echo "COnnected";
}

$strSQL = "SELECT SYSDATE FROM DUAL";

$stmt = oci_parse($dbConn,$strSQL);
if ( ! oci_execute($stmt) ){
$err = oci_error($stmt);
trigger_error('Query failed: ' . $err['message'], E_USER_ERROR);
};

while(oci_fetch($stmt)){
$rslt = oci_result($stmt, 1); print "<h3>query returned: ".$rslt."</h3>";
}
?>

Kindly suggest the error. Thanks in advance.
