# Table Data

These functions let you fetch table information.

## $this->db->list_tables();

Returns an array containing the names of all the tables in the database you are currently connected to. Example:

`$tables = $this->db->list_tables();
foreach ($tables as $table)
{
echo $table;
}`

## $this->db->table_exists();

Sometimes it's helpful to know whether a particular table exists before running an operation on it. Returns a boolean TRUE/FALSE. Usage example:

`if ($this->db->table_exists('table_name'))
{
// some code...
}`

Note: Replace table_name with the name of the table you are looking for.
