In order to run an UPDATE query with PDO just follow the steps below: create a correct SQL UPDATE statement; replace all actual values with placeholders; prepare the resulting query; execute the statement, sending all the actual values to execute in the form of array. UPDATE query.

ExampleWe start off with $db, an instance of the PDO class. After executing a query we often want to determine the number of rows that have been affected by it. The rowCount method of the PDOStatement will work nicely: $query = $db-query('DELETE FROM table WHERE name = 'John');$count = $query-rowCount;echo 'Deleted $count rows named John';NOTE: This method should only be used to determine the number of rows affected by INSERT, DELETE, and UPDATE statements.

Pdo Query

Although this method may work for SELECT statements as well, it is not consistent across all databases.

Php Pdo Num Rows Affected

Written by Saran on March 10, 2013, Updated November 22, 2017After the deprecation of PHP MySQL extension in, alternative extension MySqli and PDO are available in PHP. MySqli and PDO are improved version and offer an object-oriented API and number of enhancement over the regular MySql extension. These extensions are much faster, efficient and totally secure against SQL injections.Today I'd like to show you the basic usage of MySqli, such as connect, select, insert, update and delete records. I hope this list will come in handy for you.Installing MySqliIf you are running PHP version 5.3.0 +, MySqli should be available to use it right away, but in old PHP 5.0, 5.1, 5.2, extension is not enabled by default on Windows Systems, you must enable phpmysqli.dll DLL inside of php.ini. To enable the extension you need to edit your php.ini and remove comment (semi-colon) from the start of the line extension=phpmysqli.dll. In linux too when you install php5 mysql package, MySQLi automatically gets installed, more details about installation in Linux and Windows can be found.Connect to DatabaseMySqli offers two ways to connect to the database, procedural and object oriented, the recommended way to open a database connection is object oriented way, because it is secure, faster and efficient. The procedural style is much similar to old MySql and it may be helpful to users who are just switching to MySqli, but should keep away altogether.

Php Pdo Row

$id = 0;$productcode = 'P1234';$productname = '42 inch TV';$productdesc = '42 inch TV is good enough for movies';$price = '1000';//MySql query using ON DUPLICATE KEY UPDATE$query = 'INSERT INTO products (id, productcode, productname, productdesc, price)VALUES (?,?,?,?,?) ON DUPLICATE KEY UPDATE productcode=?, productname=?, productdesc=?, price=?' ;$statement = $mysqli-prepare($query); // Prepare query for execution//bind parameters for markers, where (s = string, i = integer, d = double, b = blob)$statement-bindparam('dsssdsssd', $id, $productcode, $productname, $productdesc, $price, //insert vars$productcode, $productname, $productdesc, $price); //update vars$statement-execute;Just pass the UNIQUE or PRIMARY value such as ID of a row to perform update, or 0 to insert new row.ConclusionMySqli is clearly a winner over the regular MySql extension in PHP, and the implementation is also not that different. I just hope this article will help you migrate/build your projects in future. I have also included some example files in download section, download it for the reference and happy coding!
