Описание
bool PharFileInfo::delMetadata
( void
)

Параметри
No parameters.
Връщани стойности
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.
Грешки/Изключения
Throws PharException if errors occurred while flushing changes to disk, and BadMethodCallException if write access is disabled.
