GlobIterator 类

(PHP 5 >= 5.3.0, PHP 7, PHP 8)

简介

遍历一个文件系统行为类似于 glob()。

NOTE: "similar fashion to glob()" GlobIterator use  stream wrapper "glob://" = use glob()

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();
}
?>
