address of functions

[Richard]

Is it possible to store the address or reference to a function in php? Maybe
using just a string and later dereferencing it?

e.g some ideas to illustrate what I mean

<?php
function myCompanyMotto( ){
echo "hello";
}

$myarr["func1"]=&myCompanyMott o;
$myarr["func2"]="myCompanyMott o";

//how to get function from myarr and call it????

?>

I'd just use call_user_func( )/call_user_func_ array(), and save the
callback either as a string for normal functions, and as an array for
object/class methods.

function myCompanyMotto( ){
echo "hello";
}
class foo{
function bar(){
echo 'class';
}
}
$myarr['func1'] = 'myCompanyMotto ';
$myarr['func2'] = array('foo','ba r');
call_user_func( $myarr['func1']);
call_user_func( $myarr['func2']);

Thanks, I had googled, but being new to PHP I hadnt found
call_user_func. Just what I want.
