                        WHERE ".$val." LIKE '"."%".$SearchAndReplace_search_term."%"."'";

Answer 1

You should consider to use REPLACE of mysql that is designed what are you looking for. before executing the command take the backup of table.

   UPDATE [your_table_name] SET [your_table_field] = REPLACE([your_table_field],
 '[string_to_find]' , '[string_to_be_replaced]')
