Should you use MySQLi?
Reasons why you should use MySQLi extension instead of the MySQL extension are many: MySQLi gives you prepared statements – a safer way of sending data to MySQL and protecting you from SQL injection. This alone should be enough for always choosing MySQLi over MySQL. MySQLi enables most of the MySQL features.
Should I use MySQLi or MySQL and why?
MySQLi supports store procedure. MySQL extension lags in security and other special features, comparatively. MySQLi extension is with enhanced security and improved debugging. Transactions are handled by SQL queries only.
Is MySQLi better than MySQL?
MySQLi has two basic advantages over MySQL; prepared statements are a great way to avoid SQL injection attacks. Secondly MySQL (or mariaDB) will do their best to optimize prepared statements and thus you have the potential for speed optimizations there.
Which is faster PDO or MySQLi?
While both PDO and MySQLi are quite fast, MySQLi performs insignificantly faster in benchmarks – ~2.5% for non-prepared statements, and ~6.5% for prepared ones. Still, the native MySQL extension is even faster than both of these.
Is it safe to use mysqli ( ) in PHP?
Or you can use PDO. The use of mysqli () functions should only be reserved for framework developers and others who are aware of all the safety issues it can bring. For everyone else, there’s PDO. It’s just as easy to use as mysqli (), and far safer.
When do I need to worry about MySQL?
The only time you’ll need to worry is if you have a situation where a multiple query sequence needs to be executed like a single query – which is called a transaction (something that MySQL supports). As long as you use a transaction whenever necessary, you shouldn’t have any data integrity problems.
Is it safe to connect to multiple databases at once?
Yes – multiple applications/clients can connect to a database simultaneously. That’s basically what a database is for. It is also perfectly safe to do so – in most situations. The database will handle individual queries in sequence, and they will not interfere with one another.
