The parentheses capture a substring in the matching expression. If there were more than 1 set, then other escapes could return those fields.
s/regexp/replacement/
Attempt to match regexp against the pattern space. If successful, replace that portion matched with replacement. The replacement may contain the special character & to refer to that portion of the pattern space which matched, and the special escapes \1 through \9 to refer to the corresponding matching sub-expressions in the regexp.

Phar::extractTo - Extract the contents of a phar archive to a directory

SYNOPSIS
public bool Phar::extractTo (string $pathto, [string|array $files], [bool $overwrite = false]) DESCRIPTION
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. Extract all files within a phar 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 within an archive to the file to delete. 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 Phar.extractTo(3) example <?php try { $phar = new Phar('myphar.phar'); $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 } ?> SEE ALSO
