Convert a phar archive to another executable phar archive file format

Description

Phar::convertToExecutable(int|null $format = null, int|null $compression = null, string|null $extension = null): Phar|null

Write

This method is used to convert a phar archive to another file format. For instance, it can be used to create a tar-based executable phar archive from a zip-based executable phar archive, or from an executable phar archive in the phar file format. In addition, it can be used to apply whole-archive compression to a tar or phar-based archive.

If no changes are specified, this method throws a BadMethodCallException.

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

Parameters

format

This should be one of Phar::PHAR, 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 all zip- and tar-based phar archives must contain .phar in their file extension in order to be processed as a phar archive.

If converting to a phar-based archive, the default extensions are .phar, .phar.gz, or .phar.bz2 depending on the specified compression. For tar-based phar archives, the default extensions are .phar.tar, .phar.tar.gz, and .phar.tar.bz2. For zip-based phar archives, the default extension is .phar.zip.

Return Values

The method returns a Phar object on success, or null on failure.

Errors/Exceptions

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(), an UnexpectedValueException if write support is disabled, and a PharException if any problems are encountered during the phar creation process.

Changelog

Version	Description
8.0.0	`format`, `compression`, and `extension` are now nullable.

Examples

A Phar::convertToExecutable() example

Using Phar::convertToExecutable():

php

<?php
try {
    $tarphar = new Phar('myphar.phar.tar');
    // convert it to the phar file format
    // note that myphar.phar.tar is *not* unlinked
    $phar = $tarphar->convertToExecutable(Phar::PHAR); // creates myphar.phar
    $phar->setStub($phar->createDefaultStub('cli.php', 'web/index.php'));
    // creates myphar.phar.tgz
    $compressed = $phar->convertToExecutable(Phar::TAR, Phar::GZ, '.phar.tgz');
} catch (Exception $e) {
    // handle the error here
}
?>
