升级PHP 5的理由:PHP 4和PHP 5性能对比(1)
PHP 4到07年年底PHP Group将不再对其进行支持了,所以为了让大家更有信心的转移到PHP 5平台上,我特别做了这个测试,看看我们PHP 4.x是否真的性能比我们的PHP 5.x要好呢!测试结果很明显,那就是PHP 5.x比php 4.x不论是面向对象还是面向过程,都要比PHP 4.x要快,所以大家完全有必要转移到PHP 5.x平台上,去体验PHP 5.x平台的各种功能和性能。
因为PHP 5包括新的对象模型,更多新特点,更快的处理速度,特别是处理面向对象代码的速度,虽然在php 4中面向对象代码的速度比较一般,但是在PHP5.x中面向对象代码的速度都超过了面向过程的速度,所以不要对面向对象的性能持有怀疑,下面的测试结果将说明这一切。

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,
