MYSQLIASSOC

Mysqli_fetch_assoc is a function in the MySQLi extension for PHP that is used to retrieve one row of data from a MySQL database result set as an associative array. When you execute a query using MySQLi and get a result, you can iterate through the rows of that result using this function.

Each row is returned as an array where the keys are the column names of the table you queried. For example, if your query selected columns named 'id' and 'name', mysqli_fetch_assoc would return an array like ['id' => 1, 'name' => 'Example Name']. This makes it easy to access the data by its column name, which is often more readable and maintainable than accessing it by numerical index.

The function returns null when there are no more rows to fetch from the result set. This typically means it's used within a while loop, like while ($row = mysqli_fetch_assoc($result)) { ... }, to process each row of the query results one by one until the end of the result set is reached. It's a fundamental function for working with database results in PHP using the MySQLi extension.
