hi, can any body help me on separating this example of data that i need to parse and seperate text just like PHPDoc. It is PHP source code.

The example string :

function one_to_tree() {
        //bla bla bla   
    return FALSE;
}


function two_to_tree() {
        //bla bla bla   
    return FALSE;
}


function three_to_tree() {

       if ($sample){ //bla bla bla   } 
    return FALSE;
}

can anybody help me how to seperate above string based on "function" word and create and array. Thank you
