After IIS installs the SSL certificate, you may encounter the problem that PHP cannot obtain data. This situation is usually caused by configuration issues. Don’t worry, here are some common solutions to help you resolve this issue.

1. Check IIS and PHP configuration: First, make sure that both IIS and PHP are configured correctly. Check whether PHP's php.ini file has configuration items about SSL, such as whether "extension=php_openssl.dll" is enabled. Then, make sure IIS has PHP enabled and that the PHP files are mapped to the correct handlers.

2. Make sure the certificate is installed correctly: If the SSL certificate is not installed correctly, it may cause connection issues. Please check if your SSL certificate is installed correctly. You can use the OpenSSL tool to verify that the certificate is installed correctly. If the certificate was installed correctly, try reinstalling the certificate.

3. Update PHP version: If your PHP version is too old, it may cause issues related to SSL connections. Try upgrading PHP to the latest version to ensure it is compatible with the latest security protocols and encryption algorithms.

4. Check for permission issues: Check that your PHP script has sufficient permissions to connect to external resources. Make sure your PHP script has access to the required files and directories and has sufficient permissions to perform the relevant operations.

5. Check firewall and port settings: Sometimes, firewall or port settings may be restricting PHP connections to external resources. Please make sure your firewall allows PHP to connect via the SSL port and that the required ports are open.

6. Contact your hosting provider or certificate authority: If you have tried the above methods and still cannot resolve the issue, we recommend that you contact your hosting provider or certificate authority. They can provide you with more specific guidance to ensure the certificate is installed and configured correctly.

Summary: When IIS installs an SSL certificate, the problem that PHP cannot obtain data may be caused by configuration issues. Make sure that IIS and PHP are correctly configured, the certificate is correctly installed, the PHP version is updated, the permissions are set correctly, and the firewall and port settings allow access. If the problem is still not resolved, it is recommended to seek help from the hosting provider or certificate authority. With these workarounds, you should be able to resolve issues with PHP getting data so that your website can function properly.
