php suggestion

Hi again guys.... I would just like to hear you oppinions about something like this...(please don't shoot me :) ) ex1: function AddToDb(mysql_scape_string($text)) {

    //enter $text to db

} which would be the same as function AddToDb($text) {

    $text = mysql_escape_string($text);
    //enter $text to db

} or ex2: function removeDigitsFromText($text) {

     //return the text striped from digits

} function AddTextToDB(removeDigitsFromText($text)) { //add text to db; } This could be very usefull although I do understand that it could cause problems (references for example) .... I know this concept looks a bit strange but just wanted to hear oppinions from the experts... :) Thanx Ante
