GlobIterator::__construct

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

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

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();

}

?>

GlobIterator doesn't have a way to support GLOB_BRACE!



<?php

$iterator = new GlobIterator(getcwd. '/*.{php,txt}'); // generate an empty array

?>
