[code]
    /* $formObj is not known here */
     if(is_int($formObj)){
       $this->formObj = sprintf("%d", $formObj);
     }else if(is_float($formObj)){
       $this->formObj = sprintf("%f", $formObj);
     else{
        $this->formObj = $formObj;
     }
    /* $this->formObj is guarenteed to be a string at this point */
[code]

My question is... is there a function already that does this?

[code]
    /* $formObj is not known here */
   $this->formObj = thefunctioniwant($formObj);
    /* $this->formObj is guarenteed to be a string at this point */
[/code]

Sure i already wrote a basic version of it... but there are types i'm not checking (yet) like "bool" etc...
I just want to know if there is something that will always returning a string equivalent of
whatever was passed into it. I'll invent the wheel again if it hasn't been done...
