Is it possible to generate a CSV protegido por Senha file from a banco MySql using PHP ? the password is to open the file on the client.

I use this PHP script to generate the CSV file:

<?php  
      //export.php  
 if(isset($_POST["export"]))  
 {  
      $connect = mysqli_connect("localhost", "root", "", "simrede"); 
      if (mysqli_connect_errno())
      {
      echo "Falha ao fazer conexão: " . mysqli_connect_error();
      }

    // Set utf8
      mysqli_set_charset($connect,"utf8");
      $connect->set_charset('utf8');
      header('Content-Type: text/csv; charset=utf-8');  
      header('Content-Disposition: attachment; filename=Cadastro_Alunos-Simrede.csv');  
      $output = fopen("php://output", "w");  
      fputcsv($output, array('lastname', 'firstname', 'department', 'institution', 'username',  'email', 'city', 'course1', 'password'),';');  
      $query = "SELECT * from cs_alunos ORDER BY institution";  
      $result = mysqli_query($connect, $query);  
      while($row = mysqli_fetch_assoc($result))  
      {
           fputcsv($output, $row,";");  
      }  
      fclose($output);  
 }  
 ?>

The quick answer is that you do not have a password-protected CSV file. But there are methods to arrive at a satisfactory result.

One would be to compress .csv and protect .zip by password. It is an efficient method because, in addition to protecting the file for reading, it also decreases the download of the file to the client.

In PHP a .zip file can be created using the class ZipArchive .

Example:

<?php

$zip = new ZipArchive();

if($zip->open('download/meu_csv_protegido.zip', ZIPARCHIVE::CREATE) !== true) {
    return false;  // Não foi possível criar o zip
}

$zip->addFile('meus_dados.csv');
$zip->setPassword('minha_senha');
$zip->close();
