RecursiveRegexIterator::ALL_MATCHES List all subdirectories and files.
<?php
$a = new RecursiveRegexIterator( new RecursiveDirectoryIterator(
'/home/songoq' ), '/mydir/i', RecursiveRegexIterator::ALL_MATCHES );
foreach( new RecursiveIteratorIterator( $a ) as $s )
{
echo $s."\n";

RecursiveRegexIterator::__construct — Creates a new RecursiveRegexIterator
Descrierea
public RecursiveRegexIterator::__construct
( RecursiveIterator
$iterator
, string $regex
, int $mode = self::MATCH
, int $flags = 0
, int $preg_flags = 0
)Creates a new regular expression iterator.
Parametri
-
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:
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().
Exemple
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";
}
}
?>
Exemplul de mai sus va afișa ceva similar cu:
No children Children: test4 test5
