PharData::convertToData — Convert a phar archive to a non-executable tar or zip file
$format = null, ?int $compression = null, ?string $extension = null): ?PharDataThis 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.
format
This should be one of Phar::TAR
or Phar::ZIP. If set to null, the existing file format
will be preserved.
compression
This should be one of Phar::NONE for no whole-archive
compression, Phar::GZ for zlib-based compression, and
Phar::BZ2 for bzip-based compression.
extension
This parameter is used to override the default file extension for a
converted archive. Note that .phar cannot 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.bz2 depending on specified compression.
For zip-based archives, the
default extension is .zip.
The method returns a PharData object on success,
or null on failure.
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.

示例 #1 A PharData::convertToData() example
Using PharData::convertToData():
<?php
try {
$tarphar = new PharData('myphar.tar');
// note that myphar.tar is *not* unlinked
// convert it to the non-executable tar file format
// creates myphar.zip
$zip = $tarphar->convertToData(Phar::ZIP);
// create myphar.tbz
$tgz = $zip->convertToData(Phar::TAR, Phar::BZ2, '.tbz');
// creates myphar.phar.tgz
$phar = $tarphar->convertToData(Phar::PHAR); // throws exception
} catch (Exception $e) {
// handle the error here
}
?>
