How can the error "Driver initialization failed for handler: gdbm: File open error" be resolved in PHP?

The error "Driver initialization failed for handler: gdbm: File open error" occurs when PHP is unable to open a GDBM file due to permission issues or incorrect file path. To resolve this error, ensure that the GDBM file exists at the specified path and that PHP has the necessary permissions to access it.

$dbm = dba_open('/path/to/gdbm/file', 'c', 'gdbm');
if (!$dbm) {
    die("Error: Unable to open GDBM file");
}
// Use the GDBM file here
dba_close($dbm);
