Hi there,
I'm trying to execute function variables. This works fine outside class
code, but gives a fatal error when run within a class. The demo code is
here:
<?php
function bar1 () {
echo "Yep, in bar1() right now\n";
}
function foo1 () {
bar1();
$a = "bar1";
print_r ($a); echo "\n";
$a();
}
class foobar {
function bar2 () {
echo "Yep, in bar2() right now\n";
}
public function foo2 () {
foobar::bar2();
$a = "foobar::bar2";
print_r ($a); echo "\n";
$a();
}
}
foo1();
$fb = new foobar ();
$fb->foo2();
?>
The error message reads:
Fatal error: Call to undefined function
foobar::bar2() in /home/paul/demo/demo.php on line 25
Is there anyone out there who can explain what's wrong in this code?
Thanks, Paul
