以下示例程序旨在说明PHP中的DirectoryIterator::getATime()函数：

示例1:

// Create a directory Iterator

$directory = new DirectoryIterator(dirname(__FILE__));

// Loop runs while directory is valid

while ($directory->valid()) {

// Check for directory element

if ($directory->isDir()) {

$file = $directory->current();

// Display the filename and last accessed time

echo $file->getFilename() . " | ATime: "

. $directory->getATime() . "
";

}

// Move to the next element

$directory->next();

}

?>

输出：

. | ATime: 1574654324

.. | ATime: 1574540515

dashboard | ATime: 1574350724

img | ATime: 1574350724

示例2:

// Create a directory Iterator

$directory = new DirectoryIterator(dirname(__FILE__));

// Loop runs for each element of directory

foreach($directory as $dir) {

$file = $directory->current();

// last accessed time

echo $dir->key() . " => " .

$file->getFilename() . " | ATime: " .

$dir->getATime() . "
";

}

?>

输出：

0 => . | ATime: 1574654324
