What is the difference between using single quotes or double quotes?

$tipoFile = "application/vnd.ms-excel";
$mimeFile = "text/plain";
$ruta = FILE_DIR . "/carga/";
$formato = 'CUOTAS'.$_SESSION['anio'].".csv";

Well, in the manual of php.net they use single and / or double quotes in many of their examples.

Both single and double quotes are used to specify strings, the reference is that the single quote specifies strings literally and the double quotes specify strings with some conversions: variables by their value and escaped values.

    $mundo = 'pepe';

    echo 'hola $mundo';
    // hola $mundo

    echo "hola $mundo";
    // hola pepe

    echo "Realiza un salto de linea al final\n";
    echo 'No realiza salto de linea al final\n';
