Natively Connect to Telegram Data in PHP

Drop the CData ODBC Driver for Telegram into your LAMP or WAMP stack to build Telegram-connected Web applications. This article shows how to use PHP's ODBC built-in functions to connect to Telegram data, execute queries, and output the results.

Configure a DSN

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Using API Key Authentication

Telegram uses Bot Tokens to authenticate API requests. You can obtain a Bot Token by creating a bot via BotFather on Telegram (https://t.me/BotFather). Once created, BotFather will provide a token in the format

123456789:ABCdefGhIJKlmNoPQRsTUVwxyZ

.

After setting the following connection properties, you are ready to connect:

• AuthScheme: Set this to APIKey.
• APIKey: Set this to your Telegram Bot Token obtained from BotFather.

Example connection string

Profile=C:\profiles\Telegram.apip;ProfileSettings='APIKey=your_bot_token';

Establish a Connection

Open the connection to Telegram by calling the or methods. To close connections, use or .

$conn = odbc_connect("CData ODBC API Source","user","password");

Connections opened with are closed when the script ends. Connections opened with the method are still open after the script ends. This enables other scripts to share that connection when they connect with the same credentials. By sharing connections among your scripts, you can save system resources, and queries execute faster.

$conn = odbc_pconnect("CData ODBC API Source","user","password");
...
odbc_close($conn); //persistent connection must be closed explicitly

Create Prepared Statements

Create prepared statements and parameterized queries with the function.

$query = odbc_prepare($conn, "SELECT * FROM AvailableGifts WHERE = ?");

Execute Queries

Execute prepared statements with .

$conn = odbc_connect("CData ODBC API Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM AvailableGifts WHERE = ?");
$success = odbc_execute($query, array(''));
 

Execute nonparameterized queries with .

$conn = odbc_connect("CData ODBC API Source","user","password");
$query = odbc_exec($conn, "SELECT , FROM AvailableGifts WHERE = ''");
 

Process Results

Access a row in the result set as an array with the function.

$conn = odbc_connect("CData ODBC Telegram data Source","user","password");
$query = odbc_exec($conn, "SELECT , FROM AvailableGifts WHERE = ''");
while($row = odbc_fetch_array($query)){
 echo $row[""] . "\n";
}

Display the result set in an HTML table with the function.

$conn = odbc_connect("CData ODBC Telegram data Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM AvailableGifts WHERE = ?");
$success = odbc_execute($query, array(''));
if($success)
 odbc_result_all($query);

More Example Queries

You will find complete information on the driver's supported SQL in the help documentation. The code examples above are Telegram-specific adaptations of the PHP community documentation for all ODBC functions.
