Examples
Example #1 RecursiveRegexIterator::__construct() example
Creates a new RegexIterator that filters all strings that start with 'test'.
<?php
$rArrayIterator?=?new?RecursiveArrayIterator(array('test1',?array('tet3',?'test4',?'test5')));
$rRegexIterator?=?new?RecursiveRegexIterator($rArrayIterator,?'/^test/',
????RecursiveRegexIterator::ALL_MATCHES);
foreach?($rRegexIterator?as?$key1?=>?$value1)?{
????if?($rRegexIterator->hasChildren())?{
????????//?print?all?children
????????echo?"Children:?";
????????foreach?($rRegexIterator->getChildren()?as?$key?=>?$value)?{
????????????echo?$value?.?"?";
????????}
????????echo?"\n";
????}?else?{
????????echo?"No?children\n";
????}
}
?>The above example will output something similar to:
No children
Children: test4 test5See Also
