Example #1 RecursiveRegexIterator::getChildren() example
<?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" ;
}
}
?>
以上例程会输出:
No children Children: test4 test5
