Creates a new RecursiveRegexIterator
Description
public RecursiveRegexIterator::__construct(
RecursiveIterator $iterator,
string $pattern,
int $mode = RecursiveRegexIterator::MATCH,
int $flags = 0,
int $pregFlags = 0
)
Parameters
-
iterator
-
The recursive iterator to apply this regex filter to.
-
pattern
-
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.
-
pregFlags
-
The regular expression flags. These flags depend on the operation mode parameter:
RegexIterator preg_flags
| 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
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
