Phar->compressAllFilesGZ — Compresses all files in the current Phar archive using Gzip compression
This method compresses all files in the Phar archive using gzip compression. The zlib extension must be enabled to take advantage of this feature. In addition, if any files are already compressed using bzip2 compression, the bzip2 extension must be enabled in order to decompress the files prior to re-compressing with gzip compression. As with all functionality that modifies the contents of a phar, the phar.readonly INI variable must be off in order to succeed.
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.
Example#1 A Phar->compressAllFilesGZ() 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->isCompressedBZIP2());
var_dump($file->isCompressedGZ());
}
$p->compressAllFilesGZ();
foreach ($p as $file) {
var_dump($file->getFileName());
var_dump($file->isCompressed());
var_dump($file->isCompressedBZIP2());
var_dump($file->isCompressedGZ());
}
?>
上例将输出：
string(10) "myfile.txt" bool(false) bool(false) bool(false) string(11) "myfile2.txt" bool(false) bool(false) bool(false) string(10) "myfile.txt" bool(true) bool(false) bool(true) string(11) "myfile2.txt" bool(true) bool(false) bool(true)
