PharData::compress

(PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL phar >= 2.0.0)

PharData::compress — Compresses the entire tar/zip archive using Gzip or Bzip2 compression

说明

public PharData::compress(int $compression, ?string $extension = null): ?PharData

For tar archives, this method compresses the entire archive using gzip compression or bzip2 compression. The resulting file can be processed with the gunzip command/bunzip command, or accessed directly and transparently with the Phar extension.

For zip archives, this method fails with an exception. The zlib extension must be enabled to compress with gzip compression, the bzip2 extension must be enabled in order to compress with bzip2 compression.

In addition, this method automatically renames the archive, appending .gz, .bz2 or removing the extension if passed Phar::NONE to remove compression. Alternatively, a file extension may be specified with the second parameter.

参数

compression: Compression must be one of Phar::GZ, Phar::BZ2 to add compression, or Phar::NONE to remove compression.
extension: By default, the extension is .tar.gz or .tar.bz2 for compressing a tar, and .tar for decompressing.

返回值

A PharData object is returned on success, or null on failure.

错误／异常

Throws BadMethodCallException if the zlib extension is not available, or the bzip2 extension is not enabled.

更新日志

版本	说明
8.0.0	`extension` is now nullable.

范例

示例 #1 A PharData::compress() example


<?php
$p = new PharData('/path/to/my.tar');
$p['myfile.txt'] = 'hi';
$p['myfile2.txt'] = 'hi';
$p1 = $p->compress(Phar::GZ); // copies to /path/to/my.tar.gz
$p2 = $p->compress(Phar::BZ2); // copies to /path/to/my.tar.bz2
$p3 = $p2->compress(Phar::NONE); // exception: /path/to/my.tar already exists
?>

This is a very irritating bug. You can use this to get around it though:

$data = 'some.test.string';
$phar = new PharData('test.tar');

$phar->compress(Phar::GZ, substr($data, strpos($data, '.') + 1));

This method destroys everything after the first dot in your filename and replaces it with the zip extension (.tar.gz, etc)

Example:

<?php

$tarfile = "2.5.0.0-RC1.tar";
$pd = new \PharData($tarfile);
$pd->buildFromDirectory("/path/to/contents");
$pd->compress(\Phar::GZ);

?>

Ends up with a file named "2.tar.gz"
