PharFileInfo::delMetadata — Deletes the metadata of the entry
参数
No parameters.
返回值
总是返回 true
。
As with all functionality that modifies the contents of
a phar, the phar.readonly INI variable
must be off in order to succeed if the file is within a Phar
archive. Files within PharData archives do not have
this restriction.
错误/异常
Throws PharException if errors occurred while flushing changes to disk, and BadMethodCallException if write access is disabled.
示例

$a = new Phar('myphar.phar');
$a['hi'] = 'hi';

$a['hi']->setMetadata('there');
var_dump($a['hi']->delMetadata());
var_dump($a['hi']->delMetadata());
} catch (Exception $e) {
// handle errors
}
?>
以上示例会输出:
