Phar::compressFiles
(PHP >= 5.3.0, PECL phar >= 2.0.0)
Phar::compressFiles — Compresses all files in the current Phar archive
Description
public void Phar::compressFiles
( int $compression
)
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.
For tar-based phar archives, this method throws a
BadMethodCallException, as compression of individual
files within a tar archive is not supported by the file format. Use
Phar::compress() to compress an entire tar-based phar archive.
For Zip-based and phar-based phar archives, this method compresses all files in the
Phar archive using the specified compression.
The zlib or bzip2
extensions must be enabled to take advantage of this feature. In addition, if any files
are already compressed using bzip2/zlib compression, the respective extension must be
enabled in order to decompress the files prior to re-compressing.
As with all functionality that modifies the contents of a phar, the
phar.readonly INI variable must be off
in order to succeed.
Parameters
-
compression
-
Compression must be one of Phar::GZ,
Phar::BZ2 to add compression, or Phar::NONE
to remove compression.
Return Values
No value is returned.
Errors/Exceptions
Throws BadMethodCallException if
the phar.readonly
INI variable is on, the zlib
extension is not available, or if any files are compressed using
bzip2 compression and the bzip2 extension
is not enabled.
Examples
Example #1 A Phar::compressFiles() example
<?php
$p = new Phar('/path/to/my.phar', 0, 'my.phar');
$p['myfile.txt'] = 'hi';
$p['myfile2.txt'] = 'hi';
foreach ($p as $file) {
var_dump($file->getFileName());
var_dump($file->isCompressed());
var_dump($file->isCompressed(Phar::BZ2));
var_dump($file->isCompressed(Phar::GZ));
}
$p->compressFiles(Phar::GZ);
foreach ($p as $file) {
var_dump($file->getFileName());
var_dump($file->isCompressed());
var_dump($file->isCompressed(Phar::BZ2));
var_dump($file->isCompressed(Phar::GZ));
}
?>
The above example will output:
string(10) "myfile.txt"
bool(false)
bool(false)
bool(false)
string(11) "myfile2.txt"
bool(false)
bool(false)
bool(false)
string(10) "myfile.txt"
int(4096)
bool(false)
bool(true)
string(11) "myfile2.txt"
int(4096)
bool(false)
bool(true)
