What is the difference between using mysql_fetch_assoc and mysql_fetch_object in PHP?

The main difference between using mysql_fetch_assoc and mysql_fetch_object in PHP is the way they return data from a MySQL database query. mysql_fetch_assoc returns an associative array where the keys are column names, while mysql_fetch_object returns an object where the properties are column names. If you prefer working with arrays, mysql_fetch_assoc is the better choice. If you prefer working with objects, mysql_fetch_object is the better choice.

// Using mysql_fetch_assoc
$result = mysql_query("SELECT * FROM table");
while ($row = mysql_fetch_assoc($result)) {
    // Access data using column names as keys
    echo $row['column_name'];
}

// Using mysql_fetch_object
$result = mysql_query("SELECT * FROM table");
while ($row = mysql_fetch_object($result)) {
    // Access data using column names as properties
    echo $row->column_name;
}
