phardata.extractto
PHARDATA.EXTRACTTO(3) 1 PHARDATA.EXTRACTTO(3)
PharData::extractTo - Extract the contents of a tar/zip archive to a directory
SYNOPSIS
bool PharData::extractTo (string $pathto, [string|array $files], [bool $overwrite = false])
DESCRIPTION
Extract all files within a tar/zip archive to disk. Extracted files and directories preserve permissions as stored in the archive. The
optional parameters allow optional control over which files are extracted, and whether existing files on disk can be overwritten. The sec-
ond parameter files can be either the name of a file or directory to extract, or an array of names of files and directories to extract. By
default, this method will not overwrite existing files, the third parameter can be set to true to enable overwriting of files. This method
is similar to ZipArchive.extractTo(3).
PARAMETERS
o $pathto
- Path to extract the given files to
o $files
- The name of a file or directory to extract, or an array of files/directories to extract
o $overwrite
- Set to TRUE to enable overwriting existing files
RETURN VALUES
returns TRUE on success, but it is better to check for thrown exception, and assume success if none is thrown.
ERRORS
/EXCEPTIONS
Throws PharException if errors occur while flushing changes to disk.
EXAMPLES
Example #1
A PharData.extractTo(3) example
<?php
try {
$phar = new PharData('myphar.tar');
$phar->extractTo('/full/path'); // extract all files
$phar->extractTo('/another/path', 'file.txt'); // extract only file.txt
$phar->extractTo('/this/path',
array('file1.txt', 'file2.txt')); // extract 2 files only
$phar->extractTo('/third/path', null, true); // extract all files, and overwrite
} catch (Exception $e) {
// handle errors
}
?>
