DirectoryIterator::valid — Check whether current DirectoryIterator position is a valid file
Check whether current DirectoryIterator position is a valid file.
Diese Funktion hat keine Parameter.
Returns TRUE if the position is valid, otherwise FALSE
Beispiel #1 A DirectoryIterator::valid() example
<?php
$iterator = new DirectoryIterator(dirname(__FILE__));
// Loop to end of iterator
while($iterator->valid()) {
$iterator->next();
}
$iterator->valid(); // FALSE
$iterator->rewind();
$iterator->valid(); // TRUE
?>
This function, as far as I can tell, returns boolean, not string.
$di = new DirectoryIterator(/path/to/iterate);
while ($di->valid())
{
echo $di->getPathname() . "\n";
$di->next();
}
