Many times the OS (operating system) and browser are unable to identify this self – signed certificate, and hence they face this glitch.

The best solution is to purchase the SSL certificate from a trustworthy CA and install the same.

  • For .PEM Format:
  • Change Php.ini (Keep SSL)
  • Go to https://curl.haxx.se/ca/cacert.pem and download cacert.pem.
  • Then, copy cacert.pem into your version of OpenSSL/Zend.

Example:/usr/local/openssl-0.9.8/certs/cacert.pem.

  • Later, open your php.ini file and edit the CURL configuration by adding cainfo = ‘/usr/local/openssl-0.9.8/certs/cacert.pem.
  • Restart your PHP and verify whether the CURL can read HTTPS URL or not.

No Change in PHP.Ini (Keep SSL)

Enter the code stated below

$ch = curl_init();

$certificate_location = ‘/usr/local/openssl-0.9.8/certs/cacert.pem’;

curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, $certificate_location);

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, $certificate_location);

Disable SSL (Not advisable)

Enter the code stated below

$ch = curl_init();

curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);

After locating the file, add the below mentioned lines:

[CA Certs]

curl.cainfo=”C:/xampp/htdocs/_certs/ca-bundle.crt”

openssl.cafile=”C:/xampp/htdocs/_certs/ca-bundle.crt”
