How to zip a folder and download it using php?

Question

I have folder named \"data\". This \"data\" folder contains a file \"filecontent.txt\" and another folder named \"Files\". The \"Files\" folder contains a \"info.txt\" file.

Use the TbsZip class to create a new zip Archive. TbsZip is simple, it uses no temporary files, no zip EXE, it has no dependency, and has a Download feature that flushes the archive as a download file.

You just have to loop under the folder tree and add all files in the archive, and then flush it.

Code example:

$zip = new clsTbsZip(); // instantiate the class
$zip->CreateNew(); // create a virtual new zip archive
foreach (...) { // your loop to scann the folder tree
  ...
  // add the file in the archive
  $zip->FileAdd($FileInnerName, $LocalFilePath, TBSZIP_FILE);
}
// flush the result as an HTTP download
$zip->Flush(TBSZIP_DOWNLOAD, 'my_archive.zip');

Files added in the archive will be compressed sequentially during the Flush() method. So your archive can contain numerous sub-files, this won't increase the PHP memory.
