Learn the basics of PHP Data Objects (PDO), including essential functions and a prepared statement. Explore transactions for complex applications, access coding exercises, and download all course files.
Learn how to fetch data with PHP Data Objects (PDO) using fetch, fetch array, and fetch column, iterating with while loops and an exec object for query results.
Learn how to use the fetch all method in PHP data objects PDO, including executing queries and retrieving results as associative or numeric arrays, with key-pair fetching for two columns.
Learn to count rows with PDO by executing a query and retrieving the number of rows, then display total reserves or no results found and hide headings when none exist.
Learn to display and handle sql errors in PDO by configuring PDO::ATTR_ERRMODE and PDO::ERRMODE_EXCEPTION on the database connection, improving debugging.
Learn to use anonymous placeholders with question marks in PDO to bind values by index, compare with named parameters, and keep the query secure by proper parameter order.
Learn to pass named parameters to a PDO statement by supplying an associative array to execute, instead of binding values with bindValue or bindParam.
Bind columns in PDO by attaching database columns to PHP variables with bindColumn, then fetch using fetch bound, allowing you to display values like ID, SSN, and salary directly.
Explore how a transaction treats multiple queries as a single unit, rolling back if any step fails, and committing only when the entire transfer succeeds.
Hi,
If you are using MYSQL. Then you need to make sure you are using the InnoDB engine, which offers transaction support, instead of the default MyISAM engine, which does not.
Cheers,

While working with PHP you have a choice to adopt any supported database. You can pick MySQL, ODBC SQLite , ODBC, IBM DB2, FireBird, PostgreSQL, 4D, CUBRID, ORACLE Database, SQL Server, Informix. And if you choose Mysql , your php application will only work with the selected database. But somehow if you have to move to some other database e.g. Sqlite then of-course you have to go through every line of your application to make it compatible with SQLite. And that’s a bit difficult.. Right?
So instead of creating individual database code we pick centralized form which is portable and that will allow you to shift within minutes in case.And that centralized code is called PDO (PHP DATA OBJECTS). Which allows you to change your database anytime you want, by just changing its connection type.
PDO Provides Common interface to any number of database systems.It allows developers to create code which is portable across many databases and platforms. That’s reflects its highest performance and and power, And on top of everything its extremely easy to write. And this course is gonna teach you how? Whether you are new to PDO or planning to shift from your existing platform to PDO.
This Course will teach you all the bread & butter of PDO. As in PDO we have multiple ways to deal with CRUD operations. That’s why 1 single project can not express all the methods. So, we will work on individual concepts step by step so that you can implement PDO in your own application out there within minutes.
