Can i use both mysql and mysqli

0. MySQLi extension added in PHP 5.5 and will work on MySQL 4.1. … MySQL provides the procedural interface. MySQLi provides both procedural and object-oriented interface.

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. MySQLi is object orientated.

Yes, it is possible.

To migrate it to MySQLi, we use the mysqli_select_db method to select the database and then the mysqli_query method to run the query and return the result. This statement is replaced with the mysqli_query method using the DROP DATABASE sql… This is a simple name change.

The MySQL extension is very slightly faster than MySQLi in most benchmarks I’ve seen reported. The difference is so slight, however, that this should probably not be your criterion for deciding between the two. Other factors dwarf the difference in performance between mysql and mysqli.

There is no difference in security. The main difference between PDO and Mysqli is that PDO supports various databases and mysqli supports only MySQL. MySQLi is also a bit faster. PDO supports 12 different drivers, opposed to MySQLi, which supports MySQL only.

Both MySQLi and PDO have their advantages: PDO will work on 12 different database systems, whereas MySQLi will only work with MySQL databases. So, if you have to switch your project to use another database, PDO makes the process easy. … Both are object-oriented, but MySQLi also offers a procedural API.

It’s still available in 5.6.

PHP 7 has removed support for the mysql extension and affects the following: … PHP 7 only allows connections to a MySQL database using mysqli or PDO_MySQL.

Both MySQLi and PDO are object oriented and do support Prepared Statements (also support Transactions, Stored Procedures and more). … Below I describe the common use of MySQLi in php development with MySQL database (it can be also used with MariaDB, an enhanced, drop-in replacement for MySQL).

PHP mysqli

The MySQLi Extension (MySQL Improved) is a relational database driver used in the PHP scripting language to provide an interface with MySQL databases. It provides both object oriented and procedural APIs. Other ways to interact with MySQL are: PDO and ORM solutions.

MariaDB vs MySQL Differences

Even though MariaDB is a fork of MySQL, these two database management systems are still quite different: MariaDB is fully GPL licensed while MySQL takes a dual-license approach. Each handle thread pools in a different way. MariaDB supports a lot of different storage engines.

MariaDB port

The default port for MariaDB is 3306.

Yes, it is. Just as two MySQL instances can coexist. MariaDB is still a drop-in replacement. … The instructions are also valid for running MySQL and MariaDB on the same server.

While MariaDB isn’t yet replacing MySQL, it has brought about good competition between the two, which can be good for innovation. With its backing of Oracle, MySQL may reign supreme for at least the near future; however, technically speaking, MariaDB could replace MySQL if a company decides it wants to make the switch.

MariaDB is only distributed with the GNU GPLv2 license. There is not a commercial license, and there will never be for legal reasons.
