# DBWrapper - Version 2.0.1
This script is a simple wrapper for SQLite3, MySQL and PgSQL, for make possible to use different BD systems without changing the functions.
## Installation
In composer:
```bash
composer require jkanetwork/dbwrapper "~2.0.1"
```
By hand: Download the php file inside src folder
## Avalible functions:
* To connect
```php
//$server is location in SQLite3
resource dbw_connect (string $tdb,string $server[,string $database, string $user,string $password]);
```
* To close
```php
//Closes connection
bool dbw_close (resource $conn);
```
* Queries
```php
//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 $multiquery);
//This do a query and fetch array (One restult), all in one function($typearray optional, see below)
resource dbw_query_fetch_array (resource $conn,string $query[, string $typearray]);
//Return query as array (All results), all in one function($typearray optional, see below)
resource dbw_query_fetch_all (resource $conn,string $query[, string $typearray]);
//dbw_fetch_all is too for queries)
```
* Using result of a query
```php
//Fetch a row. ($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
```php
// 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
-mssql/sqlsrv -> Microsoft SQL Server (Needs sqlsrv lib installed)
$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
```
