$email = 'email@example.com'; $sql = "SELECT * FROM users WHERE email = :email"; $user = $db->queryRow($sql, ['email' => $email]);
$sql = "SELECT * FROM posts ORDER BY created_at DESC LIMIT 1"; $latestPost = $db->queryRow($sql);This code will execute a SQL query to select all columns from the posts table, ordered by the created_at column in descending order, and only selecting the first row using the LIMIT clause. The queryRow method will return the results as an associative array, which will be stored in the $latestPost variable. The queryRow method is part of a package or library called "Database Abstraction Layer", which provides a set of tools for working with databases in PHP. Other methods in this library might include query, queryAll, and execute, which provide different ways of executing SQL statements and retrieving results.
