To find numerous files you can use a regex pattern with the following delimiters /, @, #, ~ in the find() method. Then chain the in() method to start the search from that directory and use get() to return the results:, _(*8)

$file = new Affinity4\File\File;
$results = $file->find('/^test[\d]{2}-[\d]{2}.json$/')->in(__DIR__)->get();

$results[0]->getPathname(); // root/files/00/01/02/test02-01.json
$results[1]->getPathname(); // root/files/00/01/02/test02-02.json

You can also search the current directory and if no files are found matching the pattern search one level up by chaining the parent() method after in():, _(*9)

$file = new Affinity4\File\File;
$results = $file->find('/^test00-[\d]{2}.php$/')->in(__DIR__)->parent()->get();

$results[0]->getPathname(); // root/files/00/test00-01.php
$results[1]->getPathname(); // root/files/00/test00-02.php

You can also search the current directory and if no files are found matching the pattern search all parent directories by chaining the parents() method after in():, _(*10)

$file = new Affinity4\File\File;
$result = $file->find('config.yml')->in(__DIR__)->parents()->get();

$result->getPathname(); // root/files/config.yml

You can also specify if you only want the one item returned using the get() method. This will return the first SplFileInfo object in the array, and not an array with one SplFileInfo object., _(*11)

$file = new Affinity4\File\File;

$result = $file->find('/^test[\d]{2}-[\d]{2}.php$/')->in(__DIR__)->parents()->get(1);

return $result->getPathname() // root/files/00/01/test01-01.php;

You can also specify exactly how many items you want returned in an array using the get() method. As long as the number is greater than one the result will be an array of SPLFileInfo objects:, _(*12)

$file = new Affinity4\File\File;
$results = $file->find('/^test[\d]{2}-[\d]{2}.php$/')->in(__DIR__)->parents()->get(2);

$results[0]->getPathname(); // root/files/00/01/test01-01.php; 
$results[1]->getPathname(); // root/files/00/01/test01-02.php;
