# PharData::convertToExecutable

(PHP 5 >= 5.3.0, PHP 7, PECL phar >= 2.0.0)

PharData::convertToExecutable — Convert a non-executable tar/zip archive to an executable phar archive

### Description

PharData::convertToExecutable ([ int `$format` [, int `$compression` [, string `$extension` ]]] ) : Phar

> 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 and throws an exception 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.

### 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
}
?>`
