PHP Data Objects (PDO) Step By Step Tutorial - Part 9: In this post, we will implement prepared statement for insert and update data. I will show simple example.
<?php
// configuration
$dbtype     = "sqlite";
$dbhost     = "localhost";
$dbname     = "test";
$dbuser     = "root";
$dbpass     = "admin";
// database connection
$conn = new PDO("mysql:host=$dbhost;dbname=$dbname",$dbuser,$dbpass);
// new data
$title = 'PHP Security';
$author = 'Jack Hijack';
// query
$sql = "INSERT INTO books (title,author) VALUES (:title,:author)";
$q = $conn->prepare($sql);
$q->execute(array(':author'=>$author,
                  ':title'=>$title));
?>
Example for update data:
<?php
// configuration
$dbtype     = "sqlite";
$dbhost     = "localhost";
$dbname     = "test";
$dbuser     = "root";
$dbpass     = "admin";
// database connection
$conn = new PDO("mysql:host=$dbhost;dbname=$dbname",$dbuser,$dbpass);
// new data
$title = 'PHP Pattern';
$author = 'Imanda';
$id = 3;
// query
$sql = "UPDATE books
        SET title=?, author=?
        WHERE id=?";
$q = $conn->prepare($sql);
$q->execute(array($title,$author,$id));
?>
