Morning all,
I'm currently testing a PHP form on the wamp64 local server, obviously this will not be used for full deployment but just to test the functionality of the PHP form.
I have PHP 7.4.33, Windows 10, & WAMP 3.3.0
The solutions I have tried (how much time do you have?)
downloaded the latest cacert from cacert.pem, uploaded to the php7.4.33\extras\ssl\ directory & altered the curl.cainfo = "C:\wamp64\bin\php\php7.4.33\extras\ssl\cacert.pem" in my php.ini file - No dice.
followed the tutorial here https://stackoverflow.com/questions/29822686/curl-error-60-ssl-certificate-unable-to-get-local-issuer-certificate - didn't even have the options in the relevant files (apart from the php.ini file) which the OP has suggested as obviously the config files have been updated since the OP posted the post, so no dice.
I've sold my sanity to the devil - no dice, so the devils is laughing at my expense. Great!
I have used the following code below, note the SSL verify set to false - guess what? Yep, you guessed it - no dice!
looked at 60,000 poorly-explained YouTube tutorials, all of whom assume you need a 15 degrees is varying fields of astrophysics.
screamed
refered 83,000 posted on here - I think you're all getting the hand of tis "no dice" result by now.
How do I bypass the SSL verification because this is getting really silly now?
<?php

try {

print $response->statusCode() . "\n";

print $response->body() . "\n";
} catch ( Exception $e ) {
