More PHP in this blog lately

Recently I work too much with PHP so naturally this blog will go in this direction. I’m trying to be short and at the point, with small but useful snippets of code. I hope that they will help you in some way.
I can’t write long and meaningless chunks of text and when I read developers books I tend to read only the code. In very rare occasions I read some other explanations - they are good when you talk about methodology or algorithm but examples are best when you talk about basics. Actually, this is just an excuse. The main reasons for more code than text in this blog is that I can’t write text.

How to make tar and tar.gz archives with PHP

This question is somewhat painful for me. Maybe I am too stupid. Anyway, if you want to make tar archive without using exec, for example on Windows machine without tar tool or any other stupid reason, here is how to do it with PHP. Its actually very easy if you know how to do it.

For example lets have a directory called dir and we want to make an archive with its content. The solution for our problem is Phar.

Here is the code that do the job:


// we want to archive all files from this directory
$dir = "dir/";

// the name of our new tar
$phar = new Phar("ourarchive.phar.tar");

// build from our dir

// we are using gzip comppression

Look carefully at the name of our archive - the parameter that we give when we create Phar object. It ends with phar.tar. If you use only .tar it will return error:
Fatal error: Uncaught exception 'UnexpectedValueException' with message 'Cannot create phar 'ourarchive.tar', file extension (or combination) not recognised
This is not fun if you are trying to create tar and you receive this message. So using file name that ends with phar.tar will fix the problem.

If you receive error:
Fatal error: Uncaught exception 'BadMethodCallException' with message 'Unable to add newly converted phar "/www/pro/ourarchive.phar.tar" to the list of phars, a phar with that name already exists'
most likely your tar file already exist.

How to make Zip archives with PHP - part 1

Actually working with zip archives isn’t that obvious that it looks from the documentation. But if you want an adventure try to make tar or tar.gz. Actually in one of my next posts I will describe the procedure. Now, we are talking about zip here.

Example: Create archive and add file to it
 // the file that we want to compress
 $file = "path/filetocompress.txt";

 // how we want to name the file in the archive
 $name = "filename.txt";
 // we need to create new object
 $zip = new ZipArchive();

 // we are using ZipArchive::open with flag CREATE to make new zip archive
 if ($zip->open("", ZipArchive::CREATE) === TRUE) {

  // here the first parameter is the file on our system
  // the second is the name to be used for this file in our new zip 
     $zip->addFile($file, $name);

     // close is used for both close and save
 } else {

     echo 'Error';

Fast PHP example - FTP file upload

Here is one fast and simple example on how to do FTP file uploads with PHP.

$ftp_server = "ftp.server.url";

$ftp_user = "user";
$ftp_password = "password";

$file_to_upload = "localfile.txt";
$remote_location = "/location/file.txt";

// set up connection or exit with message
$flink = ftp_connect($ftp_server) or exit("Can't connect to ftp server: $ftp_server");

// login or at least try  
if(ftp_login($flink, $ftp_user, $ftp_password)) {

 // if login successful use ftp_put to upload the file
 // if you upload binary files use mode FTP_BINARY
 if(ftp_put($flink, $remote_location, $file_to_upload, FTP_ASCII)) {

  echo "Success! File is uploaded!";
 } else {
  echo "Can't upload file";

} else {
 echo "Can't login with this user & password";


// close the connection
