mysqliresultfetcharray

mysqli_result_fetch_array is a function within the MySQLi extension for PHP that retrieves the next row from a result set as an associative array or a numeric array. It is used to process the results of a database query executed using the MySQLi extension.

To use mysqli_result_fetch_array, you first need to execute a MySQL query and obtain a mysqli_result object. This is typically done using functions like mysqli_query or mysqli_prepare followed by mysqli_execute. Once you have the mysqli_result object, you can call mysqli_result_fetch_array within a loop to iterate through each row of the returned data.

The function accepts an optional parameter, result_type, which determines the format of the returned array. The default value is MYSQLI_BOTH, which returns an array with both associative and numeric indices. Other options include MYSQLI_ASSOC for an associative array (where column names are the keys) and MYSQLI_NUM for a numeric array (where column numbers are the keys).

For example, if a query returns a table with columns 'id' and 'name', using MYSQLI_ASSOC would return an array like ['id' => 1, 'name' => 'Example']. Using MYSQLI_NUM would return an array like [0 => 1, 1 => 'Example'].

The function returns false when there are no more rows in the result set, signaling the end of the loop. It's important to free the result set using mysqli_free_result once all data has been fetched to release memory.
