Phar::uncompressAllFiles

(PECL phar < 2.0.0)

Phar::uncompressAllFiles — Uncompresses all files in the current Phar archive

说明

public bool Phar::uncompressAllFiles ( void )

Note:

此方法已经从 phar 扩展 2.0.0以上版本中删除。可使用 Phar::compress() ， Phar::decompress() ， Phar::compressFiles() 和 Phar::decompressFiles() 替代。

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.

This method decompresses all files in the Phar archive. If any files are already compressed using gzip compression, the zlib extension must be enabled in order to decompress the files, and any files compressed using bzip2 compression require the bzip2 extension to decompress the files. 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 bzip2 extension is not enabled and any files are compressed using bzip2 compression, or if any files are compressed using gzip compression and the zlib extension is not enabled.

范例

Example #1 A Phar::uncompressAllFiles() example

  <?php
 try {
     $p  = new  Phar ( '/path/to/my.phar' ,  0 ,  'my.phar' );
     $p [ 'myfile.txt' ] =  'hi' ;
     $p [ 'myfile2.txt' ] =  'hi' ;
     $p -> compressAllFilesGZ ();
    foreach ( $p  as  $file ) {
         var_dump ( $file -> getFileName ());
         var_dump ( $file -> isCompressed ());
         var_dump ( $file -> isCompressedBZIP2 ());
         var_dump ( $file -> isCompressedGZ ());
    }
     $p -> uncompressAllFiles ();
    foreach ( $p  as  $file ) {
         var_dump ( $file -> getFileName ());
         var_dump ( $file -> isCompressed ());
         var_dump ( $file -> isCompressedBZIP2 ());
         var_dump ( $file -> isCompressedGZ ());
    }
} catch ( Exception $e ) {
    echo  'Write operations failed on my.phar: ' ,  $e ;
}
 ?>

以上例程会输出：

string(10) "myfile.txt"
bool(true)
bool(false)
bool(true)
string(11) "myfile2.txt"
bool(true)
bool(false)
bool(true)
string(10) "myfile.txt"
bool(false)
bool(false)
bool(false)
string(11) "myfile2.txt"
bool(false)
bool(false)
bool(false)
