and here it is in action:

    $pattern = "/\{\#(.*?)\#\}/";
    $test_string =

        Lorem Ipsum is simply {#dummy#} text 
        of the printing and typesetting industry. 
        Lorem Ipsum has been the industry's {#standard#} dummy text 
        ever since the 1500s, 
        when an unknown printer took a galley of type 
        and scrambled it to make a type specimen book. 
        It has survived not only five centuries, 
        but also the leap into electronic typesetting, 
        remaining {#essentially unchanged#}. 
        It was popularised in the 1960s 
        with the release of Letraset sheets 
        containing Lorem Ipsum passages, 
        {#and more recently with desktop publishing software#} 
        like Aldus PageMaker including versions of Lorem Ipsum.

    preg_match_all($pattern, $test_string, $matches);
    print_r($matches);

//The output

        (

    [1] => Array
        (
