How can PHP beginners effectively utilize PHP functions like mysql_query and mysql_fetch_array for database queries?

PHP beginners can effectively utilize PHP functions like mysql_query and mysql_fetch_array for database queries by following these steps: 1. Use mysql_query to execute SQL queries and retrieve results from the database. 2. Use mysql_fetch_array to fetch a result row as an associative array, a numeric array, or both. 3. Loop through the results using mysql_fetch_array to process each row. 

// Connect to the database
$connection = mysql_connect("localhost", "username", "password");
mysql_select_db("database_name", $connection);

// Execute a query
$query = "SELECT * FROM table_name";
$result = mysql_query($query);

// Fetch and process the results
while ($row = mysql_fetch_array($result)) {
    // Access data in the row using column names or indexes
    echo $row['column_name'] . "<br>";
}

// Close the connection
mysql_close($connection);
