Phar::compressFiles
(PHP 5 >= 5.3.0, PHP 7, PECL phar >= 2.0.0)
Phar::compressFiles — Compresses all files in the current Phar archive
说明
public Phar::compressFiles
( int $compression
) : void
Note:
此方法需要
将 php.ini 中的 phar.readonly 设为
0 以适合 Phar
对象. 否则, 将抛出PharException.
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.
参数
-
compression
-
Compression must be one of Phar::GZ,
Phar::BZ2 to add compression, or Phar::NONE
to remove compression.
