cURL error 60: SSL certificate in Laravel 5.4

A quick solution but insecure (not recommended).

Using cURL:

Set CURLOPT_SSL_VERIYPEER to false

Using Guzzle: Set verify to false, for example

$client->request('GET', 'https://somewebsite.com', ['verify' => false]);

Do not ever modify files in the vendor/ folder. Ever. They can and will be overwritten on the next composer update you run.

Here is my Solution for WampServer

I am using PHP 7.1.9 for my WampServer, so change 7.1.9 in the example below to the version number you are currently using.

1. Download this file: http://curl.haxx.se/ca/cacert.pem
2. Place this file in the C:\wamp64\bin\php\php7.1.9 folder
3. Open php.iniand find this line:

;curl.cainfo

Change it to:

curl.cainfo = "C:\wamp64\bin\php\php7.1.9\cacert.pem"

Make sure you remove the semicolon at the beginning of the line.

Save changes to php.ini, restart WampServer, and you're good to go!
