How to delete multiple redis keys with the same pattern in PHP using phpredis?
By using phpredis, I have saved some data in pagination like this:
review/itemA/1
review/itemA/2
where 1 and 2 are page numbers. I read in the document that you can use wildcards to retrieve multiple keys.
$allKeys = $redis->keys('*'); // all keys will match this.
$keyWithUserPrefix = $redis->keys('user*');
But can I delete all the old keys using wildcards as well when someone has posted a new review? Can I do something like:
$redis->delete('review/itemA/*'); // or $redis->delete('review/itemA*')
It didn't work however.
Answer
No - Redis' DELlete does not accept wildcards, you have to name the keys explicitly. See here for possible directions: https://stackoverflow.com/a/23399125/3160475
