(PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL phar >= 1.2.0)
PharFileInfo::delMetadata — Deletes the metadata of the entry
No parameters.
Returns true if successful, false if the entry had no metadata.
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.
Throws PharException if errors occurred while flushing changes to disk, and BadMethodCallException if write access is disabled.

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