    Beispiele

    Beispiel #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());
    }
    }
    ?>

    Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

    Matched 2 item(s)
[1] php5ts.dll
[2] php_gd2.dll

    Fix problem with braces in template:<?phpclass 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    {        $this->generator = null;        return true;    }}?>Replace glob wrapper:<?phpstream_wrapper_unregister('glob');stream_wrapper_register('glob', 'GlobStreamWrapper');?>Example:<?php$iterator = new GlobIterator(__DIR__ . '/{application,system}/src/*.php');while ($iterator->valid()) {    echo $iterator->current()->getFilename() . '</br>';    $iterator->next();}?>
