Reproduce code:

<?php

$user = "hr";
$pass = "hr";
$databaseName = "//localhost/XE";

echo "<pre>"; var_dump($user, $pass, $databaseName); echo "</pre>";

$conn = oci_connect( $user, $pass, $databaseName);

echo "<pre>"; var_dump($conn); echo "</pre>";

if (!$conn) {
  echo "connection 1 failed";
  exit;
}

oci_close($conn);

$conn = oci_connect( $user, $pass, $databaseName);

echo "<pre>"; var_dump($conn); echo "</pre>";

if (!$conn) {
  echo "connection 2 failed";
  exit;
}

oci_close($conn);
