Example #1 RegexIterator::__construct() example
Creates a new RegexIterator that filters all strings that start with 'test'.
<?php
$arrayIterator = new ArrayIterator(array('test 1', 'another test', 'test 123'));
$regexIterator = new RegexIterator($arrayIterator, '/^test/');
foreach ($regexIterator as $value) {
echo $value . "\n";
}
?>
Il precedente esempio visualizzerà qualcosa simile a:
test 1 test 123
