PHP MySQL Select Query

PHP mysql_query() function is used to execute select query. Since PHP 5.5, mysql_query() function is deprecated. Now it is recommended to use one of the 2 alternatives.

  • mysqli_query()
  • PDO::__query()

There are two other MySQLi functions used in select query.

  • mysqli_num_rows(mysqli_result $result): returns number of rows.
  • mysqli_fetch_assoc(mysqli_result $result): returns row as an associative array. Each key of the array represents the column name of the table. It return NULL if there are no more rows.
