PharData::decompressFiles — Decompresses all files in the current zip archive

Description

public PharData::decompressFiles(): bool

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 archives, this method throws a BadMethodCallException, as compression of individual files within a tar archive is not supported by the file format. Use PharData::compress() to compress an entire tar-based archive.

For Zip-based archives, this method decompresses all files in the archive. The zlib or bzip2 extensions must be enabled to take advantage of this feature if any files are compressed using bzip2/zlib compression.

Parameters

This function has no parameters.

Return Values

Returns true on success or false on failure.

Errors/Exceptions

Throws BadMethodCallException if 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 PharData::decompressFiles() example


<?php
$p = new PharData('/path/to/my.zip');
$p['myfile.txt'] = 'hi';
$p['myfile2.txt'] = 'hi';
$p->compressFiles(Phar::GZ);
foreach ($p as $file) {
    var_dump($file->getFileName());
    var_dump($file->isCompressed());
    var_dump($file->isCompressed(Phar::BZ2));
    var_dump($file->isCompressed(Phar::GZ));
}
$p->decompressFiles();
foreach ($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"
int(4096)
bool(false)
bool(true)
string(11) "myfile2.txt"
int(4096)
bool(false)
bool(true)
string(10) "myfile.txt"
bool(false)
bool(false)
bool(false)
string(11) "myfile2.txt"
bool(false)
bool(false)
bool(false)
