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 how to use the fetch column method in PHP Data Objects (PDO) to retrieve a single column, saving memory while building a simple employee table.
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 how to diagnose and handle SQL errors in PHP data objects (PDO) by inspecting errorInfo to identify issues like unknown columns or missing tables, while presenting user-friendly messages.
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 how to use the PDO exec method to perform insert, update, and delete operations, track affected rows, and retrieve the last insert id.
Learn how to prevent sql injection in php apps by using prepared statements with PDO, safeguarding database queries from malicious input and ensuring safe user searches.
Discover how to implement named parameters in PHP PDO prepared statements by binding values with bindValue and bindParam, executing, and fetching results while handling errors.
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.
Learn to use anonymous placeholders (question marks) in PHP PDO, pass parameters as an array to execute, and bind values by order without named parameters.
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,

Explore transactions with php data objects (pdo) by selecting two employees, retrieving id, name and salary, formatting salaries, and preparing debit and credit entries for their accounts.
Learn to complete a transaction using pdo by checking the sender's balance with a prepared statement, rolling back on insufficient funds, and updating the receiver account balance.
Explore how to handle and display SQL errors in PHP PDO using the errorInfo function on the statement object. Diagnose missing tables and test corrections to ensure the code runs.
Practice the source code line by line to master PHP Data Objects (PDO), complete coding exercises and assignments, and explore discounted courses and tutorials on the instructor's site.
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.
