PHP Manual: Convert a non-executable tar/zip archive to an executable phar archive

Description

public Pharnull PharData::convertToExecutable(intnull $format = null, intnull $compression = null, stringnull $extension = null)

Note:
This method requires the php.ini setting phar.readonly to be set to 0 in order to work for Phar objects. Otherwise, a PharException will be thrown.

This method is used to convert a non-executable tar or zip archive to an executable phar archive. Any of the three executable file formats (phar, tar or zip) can be used, and whole-archive compression can also be performed.

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 `localName` are now nullable.

Examples

Example #1 A PharData::convertToExecutable example

Using PharData::convertToExecutable():

<?php
try {
    $tarphar = new PharData('myphar.tar');
    // convert it to the phar file format
    // note that myphar.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 = $tarphar->convertToExecutable(Phar::TAR, Phar::GZ, '.phar.tgz');
} catch (Exception $e) {
    // handle the error here
}
?>
