Phar::compressFiles
  (PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL phar >= 2.0.0)
Phar::compressFiles — Compresses all files in the current Phar archive
  
 
  Descrizione
  
   public Phar::compressFiles(
int $compression): 
void 
  Nota: 
This
method requires the php.ini setting phar.readonly to be
set to 0 in order to work for Phar
objects.  Otherwise, a PharException will be thrown.
  
   For tar-based phar archives, this method throws a
   BadMethodCallException, as compression of individual
   files within a tar archive is not supported by the file format.  Use
   Phar::compress() to compress an entire tar-based phar archive.
  
  
   For Zip-based and phar-based phar archives, this method compresses all files in the
   Phar archive using the specified compression.
   The zlib  or bzip2
   extensions must be enabled to take advantage of this feature.  In addition, if any files
   are already compressed using bzip2/zlib compression, the respective extension must be
   enabled in order to decompress the files prior to re-compressing.
   As with all functionality that modifies the contents of a phar, the
   phar.readonly INI variable must be off
   in order to succeed.
