// This iterator filters all values with less than 10 characters
class LengthFilterIterator extends FilterIterator {
public function accept() {
// Only accept strings with a length of 10 and greater
return strlen(parent::current()) >= 10;
}
}
$arrayIterator = new ArrayIterator(array('test1', 'more than 10 characters'));
$lengthFilter = new LengthFilterIterator($arrayIterator);
foreach ($lengthFilter as $value) {
echo $value . "\n";
}
?>
The above example will output:
