The method will not throw an exception, but simply return &false; like would happen with any other deletion failure. &reftitle.parameters; key The key of the entry to delete. &reftitle.returnvalues; &true; when the entry was deleted, and &false; if the entry was not deleted. &reftitle.examples; exists( 'four' ) ); var_dump( $hash->add( 'four', 5 ) ); var_dump( $hash->get( 'four' ) ); var_dump( $hash->delete( 'four' ) ); var_dump( $hash->exists( 'four' ) ); var_dump( $hash->get( 'four' ) ); var_dump( $hash->delete( 'four' ) ); ?>]]> &example.outputs.similar;
