Phar::compressFiles

(PHP >= 5.3.0, PECL phar >= 2.0.0)

Phar::compressFilesCompresses all files in the current Phar archive

Descrição

public void Phar::compressFiles ( int $compression )

Nota:

Esta função requer a configuração do arquivo php.ini phar.readonly ser definida como 0 para funcionar os objetos Phar. Caso contrário, uma PharException será disparada.

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.

Parâmetros

compression

Compression must be one of Phar::GZ, Phar::BZ2 to add compression, or Phar::NONE to remove compression.

Valor Retornado

Não há valor retornado.

Erros

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.

Exemplos

Exemplo #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));
}
?>

O exemplo acima irá imprimir:

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)

Compressing the entire archive
$phar->compress();
overrides your stub file.

Use compressFiles to have the the files compressed keeping your own stub in tact (which is not being compressed).
The compression is a little bit worth (since one file is left uncompressed), but enables you to have your own stub file executed with browser requests.

Don't get confused, compressing doesn't rise the security level of your code or obfuscating it strongly enough. The source code of your compressed phar is still easy to read.
