Hi gang:
Not that I have an immediate need for this, but in other languages
one can access a function by reference (in other words, it's address
-- such as call(function address) ).
In php, one can pass a variable by reference by simply using the
ampersand, such a &$a.
Is there a similar way to reference a function?
Rob, was kind enough to post the following code, but I was looking
for something where I could store the function's address in a
variable. Something like:
$a = &f_a();
And then, where I could use call_user_func($a); (or something
similar) and the function would do it's thing -- anything like that?
Thanks
tedd
--- Rob's suggestion follows.
Like the following?
<?php
function f_a()
{
echo 'a';
}
function f_b()
{
echo 'b';
}
function f_c()
{
echo 'c';
}
$map = array
(
'a' => 'f_a',
'b' => 'f_b',
'c' => 'f_c',
);
$map['a']();
$map['b']();
$map['c']();
?>
