PharData::convertToDataConvert a phar archive to a non-executable tar or zip file


public PharData::convertToData(?int $format = null, ?int $compression = null, ?string $extension = null): ?PharData

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.



This should be one of Phar::TAR or Phar::ZIP. If set to null, the existing file format will be preserved.


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.


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.

Valor Retornado

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.

Exemplo #1 A PharData::convertToData() example

Using PharData::convertToData():

try {
$tarphar = new PharData('myphar.tar');
// note that myphar.tar is *not* unlinked
// convert it to the non-executable tar file format
// creates
$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
