Answer 1

Use PHP 7.2 to create password protected zip file:

$zip = new ZipArchive;
$res = $zip->open('filename.zip', ZipArchive::CREATE); //Add your file name
if ($res === TRUE) {
   $zip->addFromString('FILENAME_WITH_EXTENSION', 'file content goes here'); //Add your file name
   $zip->setEncryptionName('FILENAME_WITH_EXTENSION', ZipArchive::EM_AES_256, 'PASSWORD'); //Add file name and password dynamically
   $zip->close();
   echo 'ok';
} else {
   echo 'failed';
}
