Troubleshooting "A Problem Occurred Somewhere in the SSL/TLS Handshake" Error in cURL
When attempting to establish HTTPS connections with cURL, developers may encounter the following error:
A problem occurred somewhere in the SSL/TLS handshake.
This issue arises due to cURL not having built-in root certificates like modern browsers. To resolve it, follow these steps:
Solution:
- Download the cacert.pem certificate file from http://curl.haxx.se/docs/caextract.html.
- Configure cURL to point to this file using the CURLOPT_CAINFO option:
<code class="php">curl_setopt($ch, CURLOPT_CAINFO, '/path/to/cert/file/cacert.pem');</code>
This specifies the location of the trusted root certificates that cURL should use to verify SSL certificates sent back by servers.
Additional Tips:
- Ensure that OpenSSL is installed and enabled on your system.
- Set CURLOPT_SSL_VERIFYPEER to true to enable certificate verification.
- Try different combinations of CURLOPT_SSL_VERIFYHOST (1 or 2) and CURLOPT_SSL_VERIFYPEER (true or false) to troubleshoot further.

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
