    Function that echo values, how to set them to variable?

    Hi,

    I have a class and there is a method of this class its output is get out by echo. What I need is to assign the echo value to a variable without printing it out!

    Is there any way to cache the output of this function into a variable? I don't want to change the coding of the function.

    For examle:

    class MyClass(){
    function result(){
    echo "Hello World";
    }
    }

    Usually the above example will print Hello World. I want something like the follwoing:

    $obj = new MyClass();
    $v = $obj->result(); // I don't want Hello World to be printed here???
    /* after some logic */

    echo $v; Here I want Hello World to be printed!!!
    Regards();

    Change the echo to return.

    PHP Code:
    class MyClass(){
         function 
    result(){
             return 
    "Hello World";
        }

    and then

    PHP Code:
    $obj = new MyClass();
    $v =  $obj->result();

    // add -  echo $v - wherever you want "Hello World" to appear
