Example #1 Countable::count() example

`<?php
class myCounter implements Countable {
private $count = 0;
public function count() {
return ++$this->count;
}
}$counter = new myCounter;

for( i=0;i=0; i=0;i<10; ++$i) {
echo "I have been count()ed " . count($counter) . " times\n";
}
?> `

The above example will output something similar to:

I have been count()ed 1 times I have been count()ed 2 times I have been count()ed 3 times I have been count()ed 4 times I have been count()ed 5 times I have been count()ed 6 times I have been count()ed 7 times I have been count()ed 8 times I have been count()ed 9 times I have been count()ed 10 times
