(PHP 5 >= 5.3.0, PHP 7, PECL phar >= 1.2.0)
PharFileInfo::delMetadata — Deletes the metadata of the entry
Opis
public PharFileInfo::delMetadata
( void
) : bool
Deletes the metadata of the entry, if any.
Parametry
No parameters.
Zwracane wartości
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.
Błędy/Wyjątki
Throws PharException if errors occurred while flushing changes to disk, and BadMethodCallException if write access is disabled.
