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 test5
