PharFileInfo->setUncompressed -- Uncompresses the current Phar entry within the phar, if it is compressedThis method causes the file referenced to be uncompressed and re-saved. Depending on how the file is compressed, the bzip2 or zlib extensions must be enabled to take advantage of this feature. As with all functionality that modifies the contents of a phar, the phar.readonly INI variable must be off in order to succeed.
Throws BadMethodCallException if the phar.readonly INI variable is on, or if the bzip2/zlib extension is not available.
