Connect PHP to MySQL
How we can connect PHP to MySQL?
PHP 5 and later can work with a MySQL database using:
- MySQLi extension (the ‘i’ is abbreviation for improved)
- PDO (PHP Data Objects)
Which one should we use MySQLi or PDO?
Both MySQLi and PDO have their recompenses:
- PDO will work with 12 different database systems, whereas MySQLi will only work with MySQL databases.
- So, if you have to shift your project to use alternative database, PDO makes the process easy. You only have to change the connection string and a few queries. With MySQLi, you will need to rewrite the complete code — queries included.
- Both are object-oriented, but MySQLi also offers a procedural API.
In short, you can choose whichever you want if you want to stick to MySQL otherwise you should go with PDO.
