Example #1 RegexIterator::getFlags() example
<?php
$test = array ('str1' => 'test 1', 'teststr2' => 'another test', 'str3' => 'test 123');
$arrayIterator = new ArrayIterator($test);
$regexIterator = new RegexIterator($arrayIterator, '/^test/');
$regexIterator->setFlags(RegexIterator::USE_KEY);
if ($regexIterator->getFlags() & RegexIterator::USE_KEY) {
echo 'Filtering based on the array keys.';
} else {
echo 'Filtering based on the array values.';
}
?>
以上例程会输出：
Filtering based on the array keys.
