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"; } ?>
The above example will output something similar to:
