cURL error 60: SSL certificate: unable to get local issuer certificate

Question

I use WAMP on a local development environment and am trying to charge a credit card but get the error message:

cURL error 60: SSL certificate problem: unable to get local issuer certificate

I searched a lot on Google and lots of people are suggesting that I download this file: cacert.pem, put it somewhere and reference it in my php.ini. This is the part in my php.ini:

curl.cainfo = "C:\Windows\cacert.pem"

Yet, even after restarting my server several times and changing the path, I get the same error message.

I use WAMP from the Apache Modules and have the ssl_module enabled. And from the PGP extensions I have php_curl enabled.

Still the same error message. Why is that happening?

Now I am following this fix: How to fix PHP CURL Error 60 SSL

Which suggests that I add these lines to my cURL options:

curl_setopt($process, CURLOPT_CAINFO, dirname(__FILE__) . '/cacert.pem');
curl_setopt($process, CURLOPT_SSL_VERIFYPEER, true);

Where do I add options to my cURL? Apparently not through the command line, since my CLI doesn't find the command "curl_setopt"

EDIT

This is the code I am running:

public function chargeStripe()
{
    $stripe = new Stripe;
    $stripe = Stripe::make(env('STRIPE_PUBLIC_KEY'));

    $charge = $stripe->charges()->create([
        'amount'   => 2900,
        'customer' => Input::get('stripeEmail'),
        'currency' => 'EUR',
    ]);

    dd($charge);

    // echo $charge[Input::get('stripeToken')];


    return Redirect::route('step1');
}

Working solution assuming your on Windows using XAMPP:

XAMPP server

1. Similar for other environment
   • download and extract for cacert.pem here (a clean file format/data)

https://curl.haxx.se/docs/caextract.html

2. Put it here in the following directory.

C:\xampp\php\extras\ssl\cacert.pem

3. In your php.ini put this line in this section ("c:\xampp\php\php.ini"):

;;;;;;;;;;;;;;;;;;;;
; php.ini Options  ;
;;;;;;;;;;;;;;;;;;;;

curl.cainfo = "C:\xampp\php\extras\ssl\cacert.pem"

4. Restart your webserver/apache

5. Problem solved!
