Hello Team,

I am getting error below when connecting using the form below:

<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>

<?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 Password blank";}

else

{

    $db = "(DESCRIPTION =

        (ADDRESS = (PROTOCOL = TCP)(HOST = rhis-gaia-rpt01.mtg.local)(PORT = 1521))

        (CONNECT_DATA =

          (SERVICE_NAME =migr )

        )

      )" ;

    $connect = oci_connect("migr");

    $query = "SELECT * from users WHERE userid='".$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";

    }

}

?>

Fatal error: Uncaught Error: Call to undefined function oci_connect() in /opt/lampp/htdocs/login.php:20 Stack trace: #0 {main} thrown in /opt/lampp/htdocs/login.php on line 20

Kindly help me.

    The common cause would be that environment variables like LD_LIBRARY_PATH  (and maybe ORACLE_HOME if you have a DB installed on the same computer) are not propagated through the web server.  How you need to set these varies with web servers & web server versions.

    Maybe try adding the variables to /etc/apache2/envvars ?  I found this on https://docs.joomla.org/Configuring_a_LAMPP_server_for_PHP_development/Linux_desktop

    so it may not match what you have installed.

    The next problem could be that you don't have OCI8 installed or enabled in php.ini : check this.

    Kindly advise why OCI cannot be found in php info page after I added extension=oci8.so to /opt/lampp/etc/php.ini?

       - add LIBDIR to the `LD_LIBRARY_PATH' environment variable

         during execution

       - add LIBDIR to the `LD_RUN_PATH' environment variable

         during linking

       - use the `-Wl,-rpath -Wl,LIBDIR' linker flag

       - have your system administrator add LIBDIR to `/etc/ld.so.conf'

    You probably need to review the first suggestion I made about setting the library search path.  If you have Instant Client (and no other Oracle software) installed on your computer, then you will find it easier to run ldconfig instead of setting LD_LIBRARY_PATH, see the Instant Client installation instructions.

    And if you only have Instant Client, then try a recent version.  Oracle 19c Instant Client will let you connect to Oracle Database version 11.2 or more recent.
