(PHP 5 >= 5.3.0, PHP 7)
GlobIterator::__construct — Construct a directory using glob
说明
public GlobIterator::__construct
( string $pattern
[, int $flags = FilesystemIterator::KEY_AS_PATHNAME | FilesystemIterator::CURRENT_AS_FILEINFO
] )
Constructs a new directory iterator from a glob expression.
参数
pattern- A glob() pattern.
flags- Option flags, the flags may be a bitmask of the FilesystemIterator constants.
范例
Example #1 GlobIterator example
<?php$iterator = new GlobIterator('*.dll', FilesystemIterator::KEY_AS_FILENAME);if (!$iterator->count()) { echo 'No matches';} else { $n = 0; printf("Matched %d item(s)\r\n", $iterator->count()); foreach ($iterator as $item) { printf("[%d] %s\r\n", ++$n, $iterator->key()); }}?>
以上例程的输出类似于：
Matched 2 item(s) [1] php5ts.dll [2] php_gd2.dll
