What are the benefits of using mysql_query() and mysql_fetch_array() in PHP for database operations?
Using mysql_query() and mysql_fetch_array() in PHP for database operations allows you to send SQL queries to the database and retrieve the results as an array. This makes it easy to interact with the database and manipulate the data returned from queries. Additionally, these functions help prevent SQL injection attacks by properly escaping user input.
// 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 the results as an array
while ($row = mysql_fetch_array($result)) {
// Process the data here
}
// Close the connection
mysql_close($connection);
