Looping over multiple RecursiveDirectoryIterator

Question

I currently have the following PHP:

$directoryIterator = new RecursiveDirectoryIterator( __DIR__ . \'/tests/phpunit/\' );

/**
 * @var SplFileInfo $fileInfo
         


        

Answer 1

To iterate over iterators you can use AppendIterator class.

$directoryIterator = new RecursiveDirectoryIterator( __DIR__ . '/tests/phpunit/' );
$directoryIterator1 = new RecursiveDirectoryIterator( __DIR__ . '/tests/integration/' );
$iterator = new AppendIterator();
$iterator->append(new RecursiveIteratorIterator( $directoryIterator ));
$iterator->append(new RecursiveIteratorIterator( $directoryIterator1 ));

/**
 * @var SplFileInfo $fileInfo
 */
foreach ($iterator as $fileInfo) {
    if ( substr( $fileInfo->getFilename(), -8 ) === 'Test.php' ) {
        $files[] = $fileInfo->getPathname();
    }
}
