How to set up curl ngrok using php?

@lew 

To set up curl ngrok with PHP, you can follow these steps:

1. Download and extract the ngrok executable from the official ngrok website (https://ngrok.com/download). Choose the appropriate version for your operating system.
2. Once extracted, you will have an ngrok executable file. Place this file in a directory accessible to your PHP script.
3. In your PHP script, use the exec() function to execute the ngrok command. Here's an example:

<?php
$ngrokPath = '/path/to/ngrok.exe'; // Replace with the actual path to ngrok

// Start ngrok tunnel
exec($ngrokPath . ' http 80', $output);

// Parse the ngrok output to get the tunnel URL
$url = '';
foreach ($output as $line) {
    if (strpos($line, 'Forwarding') !== false) {
        $url = trim(str_replace('Forwarding', '', $line));
        break;
    }
}

// Output the tunnel URL
echo "Tunnel URL: {$url}";
?>

Make sure to replace /path/to/ngrok.exe with the actual path to the ngrok executable file on your system.

1. Run this PHP script in a web server environment (e.g., Apache) configured to execute PHP files.
2. When you run the script, ngrok will start a tunnel and print the tunnel URL on the output page.

Note: This setup assumes you have ngrok installed and you're using it to expose a local web server running on port 80. Adjust the port number in the exec() command and the ngrok command accordingly if you're using a different port.
