rpm_is_validTests a filename for validity as an RPM file


bool rpm_is_valid ( string $filename )

rpm_is_valid() will test an RPM file for validity as an RPM file. This is not the same as rpm_open() as it only checks the file for validity but does not return a file pointer to be used by further functions.



The filename of the RPM file you wish to check for validity.

Return Values

Returns TRUE on success or FALSE on failure.
