(PHP 5 >= 5.3.0)
GlobIterator::__construct — Construct a directory using glob
Description
public GlobIterator::__construct
( string
$path
[, int $flags = FilesystemIterator::KEY_AS_PATHNAME | FilesystemIterator::CURRENT_AS_FILEINFO
] )Constructs a new directory iterator from a glob expression.
Parameters
-
path -
The path of the directory.
-
flags -
Option flags, the flags may be a bitmask of the FilesystemIterator constants.
Examples
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());
}
}
?>
The above example will output something similar to:
Matched 2 item(s) [1] php5ts.dll [2] php_gd2.dll

GlobIterator doesn’t have a way to support GLOB_BRACE!
<?php
$iterator = new GlobIterator(getcwd. '/*.{php,txt}'); // generate an empty array
?>
Fix problem with braces in template:
<?php
class GlobStreamWrapper
{
private $generator;
protected function createGenerator(array $paths): Generator
{
return yield from $paths;
}
public function dir_opendir(string $pattern, int $options = 0): bool
{
$pattern = substr($pattern, 7); // crop 'glob://' prefix
$pattern = str_replace(['\\', '/'], DIRECTORY_SEPARATOR, $pattern);
$paths = (array) glob($pattern, GLOB_BRACE | GLOB_NOSORT);
$this->generator = $this->createGenerator($paths);
return $this->generator->valid();
}
public function dir_readdir(): string
{
$path = $this->generator->current() ?: '';
$this->generator->next();
return $path;
}
public function dir_rewinddir(): bool
{
$this->generator->rewind();
return $this->generator->valid();
}
public function dir_closedir(): bool
{
$this->generator = null;
return true;
}
}
?>
Replace glob wrapper:
<?php
stream_wrapper_unregister('glob');
stream_wrapper_register('glob', 'GlobStreamWrapper');
?>
Example:
<?php
$iterator = new GlobIterator(__DIR__ . '/{application,system}/src/*.php');
while ($iterator->valid()) {
echo $iterator->current()->getFilename() . '</br>';
$iterator->next();
}
?>
