mysql_list_tables
MYSQL_LIST_TABLES(3) 1 MYSQL_LIST_TABLES(3)mysql_list_tables - List tables in a MySQL databaseSYNOPSIS
Warning
This function was deprecated in PHP 4.3.0, and will be removed in the future, along with the entirety of the original MySQL exten-
sion. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more
information. Alternatives to this function include:
oSQL Query:
SHOW TABLES FROM sometable
resource mysql_list_tables (string $database, [resource $link_identifier = NULL])
DESCRIPTION
Retrieves a list of table names from a MySQL database.
This function is deprecated. It is preferable to use mysql_query(3) to issue an SQL SHOW TABLES [FROM db_name] [LIKE 'pattern'] statement
instead.
o $database
- The name of the database
o $
link_identifier -The MySQL connection. If the link identifier is not specified, the last link opened by mysql_connect(3) is
assumed. If no such link is found, it will try to create one as if mysql_connect(3) was called with no arguments. If no connection
is found or established, an E_WARNING level error is generated.
A result pointer resource on success or FALSE on failure.
Use the mysql_tablename(3) function to traverse this result pointer, or any function for result tables, such as mysql_fetch_array(3).
