关于PHP获取时间显示的问题
如图所示 小时指针位置 错误 看了下代码 不知道什么地方错 了 求各位大大分析下
date_default_timezone_set('Asia/Shanghai');
$h = date("H");
$m = date("i");
$s = date("s");
....
$seclen=80;//秒针长度
$seca=$seclen*sin(pi()/30*$s);
$secb=$seclen*cos(pi()/30*$s);
$secx=120+$seca;
$secy=120-$secb;
imageline($timeimg,120,120,$secx,$secy,$red);
$minlen=70;//分针长度
$mina=$minlen*sin(pi()/30*$m);
$minb=$minlen*cos(pi()/30*$m);
$minx=120+$mina;
$miny=120-$minb;
imageline($timeimg,120,120,$minx,$miny,$black);
$hourlen=50;//时针长度
$houra=$hourlen*sin(pi()/30*$h);
$hourb=$hourlen*cos(pi()/30*$h);
$hourx=120+$houra;
$houry=120-$hourb;
imageline($timeimg,120,120,$hourx,$houry,$black);
回复讨论(解决方案)
有jQuery这个东东,为啥还用php来跑,,,,
$mina=$minlen*sin(pi()/30*$m);
$houra=$hourlen*sin(pi()/30*$h);
时和分秒一个12进制,一个60进制,但是求坐标的算法居然一样,肯定是这里的问题
将$h翻5倍再进入计算就对了吧

因为在看PHP GD库 知道怎么用JQ实现动态显示 只是 想用这个试一下而已
$mina=$minlen*sin(pi()/30*$m);
$houra=$hourlen*sin(pi()/30*$h);

谢谢啦 自己蠢了 一下子找不到头了 哈哈哈

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,

Article discusses late static binding (LSB) in PHP, introduced in PHP 5.3, allowing runtime resolution of static method calls for more flexible inheritance.Main issue: LSB vs. traditional polymorphism; LSB's practical applications and potential perfo

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.

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
