    Esempi

    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());
    }
    }
    ?>

    Il precedente esempio visualizzerà qualcosa simile a:

    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();
    }
    ?>
