Example #1 RegexIterator::setMode() example

<?php
$test = array ('str1' => 'test 1', 'test str2' => 'another test', 'str3' => 'test 123');

$arrayIterator = new ArrayIterator($test);
// Filter everything that starts with 'test ' followed by one or more numbers.
$regexIterator = new RegexIterator($arrayIterator, '/^test (\d+)/');
// Operation mode: Replace actual value with the matches
$regexIterator->setMode(RegexIterator::GET_MATCH);

foreach ($regexIterator as $key => $value) {
// print out the matched number(s)
echo $key . ' => ' . $value[1] . PHP_EOL;
}
?>
