public string PDO::quote ( string $string [, int $parameter_type = PDO::PARAM_STR ] )

<"Unquoted string: $string\n";
print "Quoted string: " . $conn->quote($string) . "\n";
"htmlcode">

<"Unquoted string: $string\n";
print "Quoted string:" . $conn->quote($string) . "\n";
?>

Quoted string: 'Naughty '' string'
