What are the differences between using mysql_fetch_object() and mysql_fetch_assoc() in PHP for database data retrieval?

When retrieving data from a MySQL database in PHP, the main difference between mysql_fetch_object() and mysql_fetch_assoc() is the format in which the data is returned. mysql_fetch_object() returns each row as an object with property names that correspond to the column names, while mysql_fetch_assoc() returns each row as an associative array where the keys are the column names. To choose between the two functions, consider how you prefer to access the data in your code. If you prefer object-oriented programming and accessing properties, mysql_fetch_object() may be more suitable. If you prefer working with associative arrays and accessing values by column names, mysql_fetch_assoc() may be a better choice. 

// Using mysql_fetch_object()
$result = mysql_query("SELECT * FROM table");
while ($row = mysql_fetch_object($result)) {
    echo $row->column_name;
}

// Using mysql_fetch_assoc()
$result = mysql_query("SELECT * FROM table");
while ($row = mysql_fetch_assoc($result)) {
    echo $row['column_name'];
}
