PharData::convertToData

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

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

说明

PharData::convertToData ([ int $format [, int $compression [, string $extension ]]] ) : 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.

参数

format

This should be one of 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 .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.

返回值

The method returns a PharData 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(), and a PharException if any problems are encountered during the phar creation process.

范例

Example #1 A PharData::convertToData() example

Using PharData::convertToData():

<?php
try {
    
$tarphar = new PharData('myphar.tar');
    
// note that myphar.tar is *not* unlinked
    // convert it to the non-executable tar file format
    // creates myphar.zip
    
$zip $tarphar->convertToData(Phar::ZIP);
    
// create myphar.tbz
    
$tgz $zip->convertToData(Phar::TARPhar::BZ2'.tbz');
    
// creates myphar.phar.tgz
    
$phar $tarphar->convertToData(Phar::PHAR); // throws exception
} catch (Exception $e) {
    
// handle the error here
}
?>
