DBWrapper - Version 1.4.1

This script is a simple wrapper for SQLite3, MySQL and PgSQL, for make possible to use different BD systems without changing the functions.

Avalible functions:

• To connect

  //$server is location in SQLite3
  resource dbw_connect (string $tdb,string $server[,string $database, string $user,string $password]);
  

• To close

   //Closes connection
  bool dbw_close (resource $conn);
  

• Queries

  //Does a query (array, or false if error)
  resource dbw_query (resource $conn, string $query);
  //This does a (non interactive) multiquery. Its used for load from a file/script for example.
  bool dbw_multi_query(resource $conn, string $multiquery);
  //This do a query and fetch array, all in one function($typearray optional, see below)
  resource dbw_query_fetch_array (resource $conn,string $query[, string $typearray]);
  

• Using result of a query

  //Fetch a row. ($typearray optional, see below)
  array dbw_fetch_array (resource $conn,resource $result[, string $typearray]);
  //Wrappers of dbw_fetch_array with row or assoc arguments
  array dbw_fetch_row(resource $conn,resource $result);
  array dbw_fetch_assoc(resource $conn,resource $result);
  //Goto X result of a query (Not retrieve it). If row is not specified, will be first row, 0
  bool dbw_query_goto(resource $conn,resource $result[,int $row]);
  // Wrappers to dbw_query_goto are dbw_data_seek and dbw_result_seek for compatibility
  
  //Return number of results of a query
  int dbw_num_rows(resource $conn, resource $result);
  

• Without a query

  // Escapes conflictive chars for inserting into database
  string dbw_escape_string(resource $conn,string $string);
  //Returns last insert ID
  int dbw_last_id(resource $conn);
  //Alias of dbw_last_id
  int dbw_insert_id(resource $conn);
  

• Important details

  $tdb (Type of database) can be:
      -mysql/mysqli -> MySQL or MariaDB
      -sqlite/sqlite3 -> Sqlite3
      -PostgreSQL/PgSQL/pg -> PostgreSQL
  
  $conn is the connection stablished in dbw_connect (ie. $conn = dbw_connect('sqlite','file.sqlite'))
  
  $typearray is the form of array is returned, and not writed is default:
      -ASSOC -> Associative indexes
      -NUM -> Numeric indexes
      -BOTH -> (Default) Both types of indexes
