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

    Convert a phar archive to another executable phar archive file format

    说明

    publicPhar::convertToExecutable([int $format= 9021976[,int $compression= 9021976[,string $extension]]]): Phar
    Note:

    此方法需要将php.ini中的phar.readonly设为0以适合Phar对象.否则,将抛出PharException.

    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.

    参数

    $format

    This should be one ofPhar::PHAR,Phar::TAR, orPhar::ZIP. If set to NULL, the existing file format will be preserved.

    $compression

    This should be one ofPhar::NONEfor no whole-archive compression,Phar::GZfor zlib-based compression, andPhar::BZ2for 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.pharin 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.bz2depending 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.

    返回值

    The method returns a Phar object on success and throws an exception on failure.

    错误/异常

    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.

    范例

    A Phar::convertToExecutable() example

    Using Phar::convertToExecutable():

    <?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
    }
    ?>

    Convert to executable and compress methods override any stub you have created with their own stub which is responsible for extracting/executing self's content.
    calling setStub() after convertingToExecutable doesn't help either. As far of php 5.3.6 (phar   2.0.1 ) if you want to have a phar archive accessible threw the web, you'll have to create your own 
    index.php which will include a nonexecutable phar and act as the bootstrap.
