Are there any best practices or recommended resources for troubleshooting PHP-Oracle connection issues?

To troubleshoot PHP-Oracle connection issues, it is recommended to check the Oracle Instant Client installation, ensure the PHP OCI8 extension is enabled, verify the connection settings in the PHP code, and check for any error messages in the PHP error logs. 

<?php
$tns = "(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = your_service_name)
    )
  )";

$conn = oci_connect('username', 'password', $tns);

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

// Perform database operations here

oci_close($conn);
?>
