How can one ensure that the extracted files are saved with the correct names and content in PHP?

To ensure that the extracted files are saved with the correct names and content in PHP, you can use the ZipArchive class to extract the files and then iterate through each extracted file to save them with their original names. You can use the getNameIndex() method to get the original file name from the zip archive.

$zip = new ZipArchive;
$res = $zip->open('example.zip');
if ($res === TRUE) {
    for ($i = 0; $i < $zip->numFiles; $i++) {
        $filename = $zip->getNameIndex($i);
        $fileContent = $zip->getFromIndex($i);
        file_put_contents($filename, $fileContent);
    }
    $zip->close();
} else {
    echo 'Failed to open the zip file';
}
