Return array of supported compression algorithms

array Phar::getSupportedCompression ( void )

No parameters.

Returns an array containing any of Phar::GZ or Phar::BZ2, depending on the availability of the zlib extension or the bz2 extension.

PharFileInfo::getCompressedSize() - Returns the actual size of the file (with compression) inside the Phar archive
PharFileInfo::isCompressed() - Returns whether the entry is compressed
PharFileInfo::compress() - Compresses the current Phar entry with either zlib or bzip2 compression
PharFileInfo::decompress() - Decompresses the current Phar entry within the phar
Phar::compress() - Compresses the entire Phar archive using Gzip or Bzip2 compression
Phar::decompress() - Decompresses the entire Phar archive
Phar::canCompress() - Returns whether phar extension supports compression using either zlib or bzip2
Phar::isCompressed() - Returns Phar::GZ or PHAR::BZ2 if the entire phar archive is compressed (.tar.gz/tar.bz and so on)
Phar::compressFiles() - Compresses all files in the current Phar archive
Phar::decompressFiles() - Decompresses all files in the current Phar archive
