PharFileInfo::isCompressedBZIP2

(PHP >= 5.3.0, PECL phar >= 1.0.0)

PharFileInfo::isCompressedBZIP2 — Returns whether the entry is compressed using bzip2

说明

public bool PharFileInfo::isCompressedBZIP2 ( void )

Note:

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

This returns whether a file is compressed within a Phar archive with Bzip2 compression.

返回值

TRUE if the file is compressed within the Phar archive using Bzip2, FALSE if not.

范例

Example #1 A PharFileInfo::isCompressedBZIP2() example

  <?php
 try {
     $p  = new  Phar ( '/path/to/my.phar' ,  0 ,  'my.phar' );
     $p [ 'myfile.txt' ] =  'hi' ;
     $p [ 'myfile2.txt' ] =  'hi' ;
     $p [ 'myfile3.txt' ] =  'hi' ;
     $p [ 'myfile2.txt' ]-> setCompressedGZ ();
     $p [ 'myfile3.txt' ]-> setCompressedBZIP2 ();
     $file  =  $p [ 'myfile.txt' ];
     $file2  =  $p [ 'myfile2.txt' ];
     $file3  =  $p [ 'myfile3.txt' ];
     var_dump ( $file -> isCompressedBZIP2 ());
     var_dump ( $file2 -> isCompressedBZIP2 ());
     var_dump ( $file3 -> isCompressedBZIP2 ());
} catch ( Exception $e ) {
    echo  'Create/modify on phar my.phar failed: ' ,  $e ;
}
 ?>

以上例程会输出：

bool(false)
bool(false)
bool(true)
