Are there any online resources or test versions available for practicing Oracle database interactions with PHP to troubleshoot issues like ORA-00000 and ORA-01002?

When encountering Oracle database issues like ORA-00000 (normal, successful completion) or ORA-01002 (fetch out of sequence), it is important to ensure that the SQL queries are correctly structured and executed in the PHP code. One common solution is to properly handle error messages and exceptions to identify the root cause of the problem. Additionally, checking the data retrieval process and ensuring the correct sequence of fetching data can help resolve ORA-01002 errors. 

<?php
$conn = oci_connect('username', 'password', 'localhost/XE');

if (!$conn) {
    $e = oci_error();
    trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}

$query = 'SELECT * FROM table_name';
$stid = oci_parse($conn, $query);
$result = oci_execute($stid);

if (!$result) {
    $e = oci_error($stid);
    trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}

while ($row = oci_fetch_array($stid, OCI_ASSOC + OCI_RETURN_NULLS)) {
    // Process fetched data
}

oci_free_statement($stid);
oci_close($conn);
?>
