PHP ZipArchive gives Invalid or uninitialized Zip object error on extraction

Question

I'm having trouble extracting file some files from zip using ZipArchive

Here is my code

$pp_saved_zip_archive = "$extract_path/archive.zip";
$zip = new ZipArchive;
$res = $zip->open($pp_saved_zip_archive, ZipArchive::CREATE);
$zip->extractTo($previews_path);
$zip->close();

I get two errors/warnings in this code

PHP Warning: ZipArchive::extractTo(): Invalid or uninitialized Zip object in...
PHP Warning: ZipArchive::close(): Invalid or uninitialized Zip object in...

If I check for $res variable it returns 19 , which is weird, it should be either TRUE or FALSE

My paths are correct, so it's not a path problem. This is done behind WordPress, I've tried $_SERVER['DOCUMENT_ROOT'] and ABSPATH to no avail. I also tried with different zip files, still no luck.

Answer 1

$result = $zipArchive->open("The archive you want to open");
if ($result === TRUE) {
    $zipArchive ->extractTo("my_dir");
    $zipArchive ->close();
    // Do something else on success
} else {
    // Do something on error
}
