Step 2: PHP Code to Fetch Stock Data
Create a PHP file (e.g., stock-data.php) and add:
<?php
$symbol = 'AAPL'; // Change to any symbol
$apiKey = 'demo'; // Replace with your key
$url = "https://www.alphavantage.co/query?function=TIME_SERIES_INTRADAY&symbol=$symbol&interval=1min&apikey=$apiKey";
$data = file_get_contents($url);
$json = json_decode($data, true);
if (isset($json['Time Series (1min)'])) {
$latest = array_key_first($json['Time Series (1min)']);
$price = $json['Time Series (1min)'][$latest]['1. open'];
echo "<h2>$symbol: $$price</h2>";
} else {
echo "<p>API Limit reached or invalid symbol.</p>";
}
