What common error message occurs when using mysql_fetch_object in PHP?

When using mysql_fetch_object in PHP, a common error message that occurs is "Call to undefined function mysql_fetch_object()." This error happens because the function mysql_fetch_object is deprecated in PHP and has been removed in newer versions. To solve this issue, you should use MySQLi or PDO extensions to fetch objects from a MySQL database instead.

// Connect to the database using MySQLi
$mysqli = new mysqli("localhost", "username", "password", "database");

// Check connection
if ($mysqli->connect_error) {
    die("Connection failed: " . $mysqli->connect_error);
}

// Query to fetch data as object
$result = $mysqli->query("SELECT * FROM table");

// Fetch object from result
while ($row = $result->fetch_object()) {
    // Process the object data
    echo $row->column_name . "<br>";
}

// Close connection
$mysqli->close();
