RegexIterator::__construct — Create a new RegexIterator
Create a new RegexIterator which filters an Iterator using a regular expression.
The iterator to apply this regex filter to.
The regular expression to match.
Operation mode, see RegexIterator::setMode() for a list of modes.
Special flags, see RegexIterator::setFlags() for a list of available flags.
The regular expression flags. These flags depend on the operation mode parameter:
| operation mode | available flags |
|---|---|
| RegexIterator::ALL_MATCHES | See preg_match_all(). |
| RegexIterator::GET_MATCH | See preg_match(). |
| RegexIterator::MATCH | See preg_match(). |
| RegexIterator::REPLACE | none. |
| RegexIterator::SPLIT | See preg_split(). |
Beispiel #1 RegexIterator::__construct() example
Creates a new RegexIterator that filters all strings that start with 'test'.
<?php
$arrayIterator = new ArrayIterator(array('test 1', 'another test', 'test 123'));
$regexIterator = new RegexIterator($arrayIterator, '/^test/');
foreach ($regexIterator as $value) {
echo $value . "\n";
}
?>
Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
test 1 test 123
