I assumed you want to connect php with oracle databases. so, I give you two of file, this is represent a basic php-oracle for your reference. good luck!

form.php

<form name="form1" method="post" action="login.php">  <label> User Name  <input type="text" name="nis" id="nis">  </label>  <label> Password  <input type="password" name="password" id="password">  </label>  <label>  <input type="submit" name="submit" id="button" value="Login">  </label></form>

login.php

<?php//create table users (userid varchar2(10), password varchar2(20), constraint pk_users primary key (userid));//insert into users values('kharis', 'pass123');$nis = isset($_POST['nis']) == true ? $_POST['nis'] : '';$password= isset($_POST['password']) == true ? $_POST['password'] : '';if(empty($nis) or empty($password)){    echo "UserID atau Password kosong";}else{    $db = "(DESCRIPTION =        (ADDRESS = (PROTOCOL = TCP)(HOST = patronus.ad-ins.com)(PORT = 1521))        (CONNECT_DATA =          (SERVER = DEDICATED)          (SERVICE_NAME = XE)        )      )" ;    $connect = oci_connect("HR", "hr", "XE");    $query = "SELECT * from users WHERE userid='".$nis."' and password='".$password."'";    $result = oci_parse($connect, $query);    oci_execute($result);    $tmpcount = oci_fetch($result);    if ($tmpcount==1) {        echo "Login Success";}    else    {        echo "Login Failed";    }}?>

PHP provides Oracle OCI8 functions. Other options are PDO with the Oracle Driver and (if oracle supports it) ODBC.
