Idea taken from here - this time you can only use PHP. Is this even possible?
Here's an interesting oo solution based on PHP's overloading:
class thousand_printer {
public function __construct() {
$this->print1();
}
public function __call($method, $_) {
$count = str_replace('print', '', $method);
echo "$count ";
$this->{"print" . ++$count}();
}
public function print1000() {
echo "1000\n";
}
}
new thousand_printer;
I'm glad my solution is so popular. Here's a slight improvement that offers some modularity:
class printer {
public function __construct() {
$this->print1();
}
public function __call($method, $_) {
$count = str_replace('print', '', $method);
echo "$count ";
$this->{"print" . ++$count}();
}
}
class thousand_printer extends printer {
public function print1001() {}
}
new thousand_printer;
print implode("\n", range(1, 1000));
<?php
class Evil
{
function __construct($c) {
$this->c = $c;
}
function __call($name, $args) {
echo $this->c . "\n";
$this->c += 1;
$this->tick();
}
// The bomb
function tick() {
call_user_func(__NAMESPACE__ .'\Evil::__' . $this->c);
}
// 007
function __1000() {}
}
$devil = new Evil(1);
$devil->tick();
?>
