php中magickwand库生成GIF格式图片保存或输出时非常慢,有人知道原因吗?
因为GD库没有写GIF动图的功能,所有用MAGICKWAND来实现,确实是非常好用,但我用XDEBUG发现生成GIF图(越大越明显)时不管是保存到文件还是直接输出都非常慢,当我用JPG/PNG格式时就不会有这样的问题,以下是代码说明:

$newMw = newmagickwand();
magicksetformat($newMw,'gif');
magickreadimage($newMw,'old.gif');
MagickWriteImages($newMw,'filename.gif');
?>
以上代码执行要花 700ms!!!


$newMw = newmagickwand();
magicksetformat($newMw,'jpg');
magickreadimage($newMw,'old.gif');
MagickWriteImages($newMw,'filename.gif');
?>
而以上代码只要 30ms!!!


------解决方案--------------------
不知道 是你的服务器问题 吧
------解决方案--------------------
magicksetformat($newMw,'gif'); 这句最好写成 magicksetformat($newMw,'GIF');

我这里测试都挺慢的 jpg的0.3秒 gif的0.5秒
( PHP4.4.8 ImageMagick 6.3.4 )

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

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,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

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.
