Phar::decompressFiles

(PHP 5 >= 5.3.0, PHP 7, PECL phar >= 2.0.0)

Phar::decompressFilesDecompresses all files in the current Phar archive

说明

public Phar::decompressFiles ( void ) : bool

Note:

此方法需要 将 php.ini 中的 phar.readonly 设为 0 以适合 Phar 对象. 否则, 将抛出PharException.

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 decompresses all files in the Phar archive. The zlib or bzip2 extensions must be enabled to take advantage of this feature if any files are compressed using bzip2/zlib compression. As with all functionality that modifies the contents of a phar, the phar.readonly INI variable must be off in order to succeed.

返回值

成功时返回 TRUE, 或者在失败时返回 FALSE

错误/异常

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.

范例

Example #1 A Phar::decompressFiles() example

<?php
$p 
= new Phar('/path/to/my.phar'0'my.phar');
$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));
}
?>

以上例程会输出:

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)
