Demonstrates how to call the CloseAllConnections method. Chilkat2 PHP

<?php

use Chilkat2\Http;
use Chilkat2\StringBuilder;

$http = new Http();

// Demonstrate
$url = 'https://finnhub.io/api/v1/quote?symbol={$symbol}&token={$api_key}';

// When the request is sent, the {$symbol} is replaced with "MSFT"
// and the {$api_key} is replaced with "1234567890ABCDEF"
$http->SetUrlVar('symbol', 'MSFT');
$http->SetUrlVar('api_key', '1234567890ABCDEF');

$sbJson = new StringBuilder();
try {
    $http->QuickGetSb($url, $sbJson);
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

$statusCode = $http->LastStatus;
echo $http->LastResponseHeader, "\n";

// The response header contains this:

// Date: Tue, 19 Aug 2025 12:18:56 GMT
// Content-Type: application/json; charset=utf-8
// Transfer-Encoding: chunked
// Connection: keep-alive
// Content-Encoding: gzip

// The "Connection: keep-alive" header ensures the server keeps the connection open for subsequent requests.
// If the server responds with a "Connection: close" header, it indicates the connection will be closed after the response.
// Consequently, Chilkat will also close the connection, requiring a new one to be established for any subsequent requests to the same server.

// If your application uses the same HTTP object instance to send requests to a different server, a new connection will be established with that server.
// Existing connections remain open, with Chilkat maintaining up to 10 open connections.
// If all 10 connections are in use, Chilkat will close the least recently used connection to connect to a new server.

// Your application can explicitly close all open connections like this:
try {
    $http->CloseAllConnections();
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

echo "Success.\n";
