Creates a new RegexIterator that filters all entries whose key starts with 'test'.
<?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 );
foreach ( $regexIterator as $key => $value ) {
echo $key . ' => ' . $value . "\n" ;
}
?>
以上例程会输出:
teststr2 => another test
