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 ;
}
?>
以上例程的输出类似于:
str1 => 1 str3 => 123
