PHP how to make work curl with CURLOPT_SSL_VERIFYHOST or fix php curl SSL certificate

If you want your curl request to work, you have two options

Method 1: Disable SSL_VERIFY (meh)

Add options to your curl request.

curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

Also disabling verify host will work for ya. But you can’t be sure all curl requests have this options. So I strongly recommend to fix the root of the cause.

Method 2: Add certificate to your php.ini (good)

Download certificate from here https://curl.se/docs/caextract.html and save it to C:\php\cacert.pem

Change values in php.ini

curl.cainfo="C:\php\cacert.pem"
openssl.cafile="C:\php\cacert.pem"

Make sure this line is uncommented

extension=openssl

In older versions it can be this

extension=php_openssl.dll
