[PHP] Functions Returning large strings

2005-09-29 Thread zzapper 
Hi,

I have a series of nested functions which return a large string (as apposed to 
working on global
string) , is this inefficient? Or is PHP clever enough to just pass a pointer?

to simplify

$large_string=fn_one(fn_two(fn_three(;


your advice pls

PHP is by no means cleaver enough to read your mind as to what you want it to 
do.

If you want to pass pointers instead of strings then do as this

function one($buffer)
{
 #processing, return true/false based on success, put result in buffer
}

function two($buffer)
{
 #processing,...
}

Then do like this:

$variable='input value';
if(one($variable))
 if(two($variable))
 echo Result: $variable;
