(PHP 5 >= 5.2.0, PHP 7)
Creates a new RecursiveRegexIterator.
public RecursiveRegexIterator::__construct ( RecursiveIterator
$iterator
, string $regex
[, int $mode
= self::MATCH [, int $flags
= 0 [, int $preg_flags
= 0 ]]] )Creates a new regular expression iterator.
Parameters:
iterator
The recursive iterator to apply this regex filter to.
regex
The regular expression to match.
mode
Operation mode, see RegexIterator::setMode() for a list of modes.
flags
Special flags, see RegexIterator::setFlags() for a list of available flags.
preg_flags
The regular expression flags. These flags depend on the operation mode parameter:
operation mode | available flags |
---|---|
RecursiveRegexIterator::ALL_MATCHES | See preg_match_all(). |
RecursiveRegexIterator::GET_MATCH | See preg_match(). |
RecursiveRegexIterator::MATCH | See preg_match(). |
RecursiveRegexIterator::REPLACE | none. |
RecursiveRegexIterator::SPLIT | See preg_split(). |
Examples:
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
