Why does mysql_num_rows provide a different approach to handling empty arrays compared to is_array in PHP?

mysql_num_rows provides a different approach to handling empty arrays compared to is_array in PHP because mysql_num_rows specifically counts the number of rows returned by a MySQL query, while is_array simply checks if a variable is an array. To handle empty arrays using mysql_num_rows, you can check if the result is equal to 0 to determine if the query returned no rows. In contrast, is_array would return false if the variable is empty, regardless of whether it represents an array or not. 

// Using mysql_num_rows to handle empty arrays
$result = mysql_query("SELECT * FROM table");
if(mysql_num_rows($result) == 0){
    echo "No rows found.";
} else {
    // Process the rows
}
