@akaash19authorMay 17.2008 — ofcourse that is the normal way but i am getting this function name string dynamically.I did it to make simple

<?php

//i have the function name as string.

$fname = getfunctionname();

//i want to call the function.

$fname.'()';

//this throws an error.

?>

let us say that getfunctionname() returned me 'akaash'.

then i want to call akaash().

thanks all

@Phill_PaffordMay 17.2008 — not sure I am following, are you trying to create a function dynamically?

does the akaash() function already exists? or are you trying to make the function from the name passed in?

@akaash19authorMay 21.2008 — First..thanks for replying phill and nogdog.

Yes..the function already exists..

i tried call_user_func() and it really solved the problem.

Interestingly i came across on php concept of php variable functions.

reading further i came to knw it is even faster than call_user_func().

all we have to do is to append () to the function name string and it works.

SO all i did was

<?php

$fname = getfunctionname();

$fname();

?>

and it worked..

again thanks to you guys...i just love this forum as i always get replies and got many problems solved..
