This example illustrates how to count the rows of the table.

To understand how to count the number of rows in a table, we have created a sql_num_rows.php file. If you are not connected to the database, then create a connection first using mysql_connect("hostName", "userName", "Password") and mysql_select_db("databaseName", connectionObject). Now the query can be executed using mysql_query("SELECT * FROM tableName"). The number of rows are returned by the mysql_num_rows() method.

  $sql = "SELECT * from users";

  $res = mysql_query($sql);

  if (!$res) {
  print("SQL statement failed with error:\n");
  print(mysql_error($con));
  else {
  $number_of_rows = mysql_num_rows($res);
  print("$number_of_rows rows found");
