There is the line marked with '#*' in the following script. One line up
you will find other line that should make the exactly same action (I
think). Try to comment this line and uncomment line with '#*'. The
output will differ. Why?
--- SCRIPT: START ---
<PRE><?php
class test {
function test() {
extfunc($this);
}
}
#___________________________________________________________
function extfunc(&$ref) {
global $obj;
$GLOBALS["obj"]=&$ref; # This is the same as '$obj=&$ref;'. Isn't
it?
#* $obj=&$ref;
}
#===========================================================
$test=new test();
var_dump($obj);
?></PRE>
--- SCRIPT: END ---
