说明

PharData::convertToData([int $format[,int $compression[,string $extension]]]): PharData

PharData::convertToData() - PharData类

This method is used to convert a non-executable tar or zip archive to another non-executable format.

If no changes are specified, this method throws a BadMethodCallException. This method should be used to convert a tar archive to zip format or vice-versa. Although it is possible to simply change the compression of a tar archive using this method, it is better to use the PharData::compress() method for logical consistency.

If successful, the method creates a new archive on disk and returns a PharData object. The old archive is not removed from disk, and should be done manually after the process has finished.

参数

$format

This should be one ofPhar::TARorPhar::ZIP. If set to NULL, the existing file format will be preserved.

$compression

This should be one ofPhar::NONEfor no whole-archive compression,Phar::GZfor zlib-based compression, andPhar::BZ2for bzip-based compression.

$extension

This parameter is used to override the default file extension for a converted archive. Note that.pharcannot be used anywhere in the filename for a non-executable tar or zip archive.

If converting to a tar-based phar archive, the default extensions are.tar,.tar.gz, and.tar.bz2depending on specified compression. For zip-based archives, the default extension is.zip.

返回值

The method returns a PharData object on success and throws an exception on failure.

错误／异常

This method throws BadMethodCallException when unable to compress, an unknown compression method has been specified, the requested archive is buffering with Phar::startBuffering() and has not concluded with Phar::stopBuffering(), and a PharException if any problems are encountered during the phar creation process.
