What are the implications of handling large files in PHP when it comes to extracting archives?

When handling large files in PHP, memory consumption can become a concern, especially when extracting archives. To avoid memory exhaustion, it is recommended to extract the archive file in chunks rather than loading the entire file into memory at once. This can be achieved by using libraries like `ZipArchive` which provide methods for incremental extraction. 

$zip = new ZipArchive;
$res = $zip->open('archive.zip');
if ($res === TRUE) {
    $zip->extractTo('/path/to/extract/');
    $zip->close();
    echo 'Archive extracted successfully';
} else {
    echo 'Failed to extract archive';
}
