PharFileInfo::setUncompressed

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

PharFileInfo::setUncompressed — Uncompresses the current Phar entry within the phar, if it is compressed

说明

public bool PharFileInfo::setUncompressed ( 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 method decompresses the file inside the Phar archive. Depending on how the file is compressed, the bzip2 or zlib extensions must be enabled to take advantage of this feature. 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, or if the bzip2/zlib extension is not available.

范例

Example #1 A PharFileInfo::setUncompressed() example

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

以上例程会输出：

bool(true)
bool(false)
