We will not implement this in the core, but you can use the runkit pecl
extension - which has similar features.

Description:
------------
A very helpful and nice feature for PHP would be to overload builtin
functions. As PHP5 now features the functions echo and print are
calling the method __toString if it exists in a class, that feature is
still lacking in many other functions where they may be useful (like
sprintf, printf, just to name a few).
To prevent that PHP developers have to do alot of work and to provide a
general interface, something like the following pseudo code demonstrates
overloading builtin functions:
<?php
function myOwnEcho ()
{
$ts = date("Y-m-d H:i:s");
print ($ts . " ");
$num_args = func_num_args();
for ($i=0; $i < $num_args; $i++)
{
print (func_get_arg($i));
}
}
overload_function("echo", "myOwnEcho");
echo "foo";
?>
Results in:
2004-04-21 15:09:01 foo
I know that echo is a language construct and not a function, it's just
been used because most PHP developers use echo for output.
