Under what conditions do I need to single quote a variable in a Mysql statement in PHP?
If you put values directly in the query, as in
SELECT * FROM users WHERE age > 25, then the single quotes are used only with strings. If you writeSELECT * FROM users WHERE age > '25', the query works the same, but you are forcing MySQL to convert the string to an integer (if that field is an integer), which is a not necessary operation.
