PHP CURL CURLOPT_SSL_VERIFYPEER Ignored: Troubleshooting HTTPS Requests

Certain actions taken with HTTPS requests in PHP can lead to the error message "Problem with the SSL CA cert (path? access rights?)". To resolve this issue and bypass certificate verification, follow these steps:

Option 1: Disable Host and Peer Verification

If you're aware of the security implications and wish to disable certificate verification, set the following options:

<code class="php">curl_setopt($cHandler, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($cHandler, CURLOPT_SSL_VERIFYPEER, true);</code>

Option 2: Specify Alternate Certificates

Assign alternate certificates to verify against using the CURLOPT_CAINFO option:

<code class="php">curl_setopt($cHandler, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($cHandler, CURLOPT_CAINFO, getcwd() . "/positiveSSL.ca-bundle");</code>

Option 3: Use the CURLOPT_SSL_VERIFYHOST Option

Specify the verification level for the host certificate using CURLOPT_SSL_VERIFYHOST:

• 0: Ignore host certificate verification
• 1: Check common name existence
• 2: Check common name existence and match with hostname

Use curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); to disable host verification.

Remember that disabling certificate verification can compromise the security of your application. Ensure you understand the implications before proceeding.
