+⚡️ Database Tip
+
+Sometimes you have seldom used queries and you can't add an index on columns for these queries. A nice trick is to use another indexed condition so the rows are filtered by the indexable column first and afterwards again for the more limiting condition.

+Remembered this great tip recently, and it's nice to see how fast PHP evolves 
+
+The exact same behavior can be implemented using match () with a default value, which also removes the need for the second callback ⚡️  https://twitter.com/reinink/status/1233017064492761088

+
+Here, the retry function tries the callback 3 times, with a 2 second interval in-between retries.

+🔥 You can use array spreading to pass an array as arguments to another function. #php
+
