# PharFileInfo::delMetadata

PharFileInfo::delMetadata — Deletes the metadata of the entry

### Opis

bool PharFileInfo::delMetadata ( void )

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.
