<?php    $t=imagecreatetruecolor(100,100);    $red=imagecolorallocate($t,255,0,0);    imagefill($t,0,0,$red);    header('Content-type:image/png');    imagepng($t);    imagedestroy($t);?>

回复讨论(解决方案)

我这边很正常，把header('Content-type:image/png'); 先去掉看看有什么错误输出。
是否有安装gd?

注释掉header('Content-type:image/png'); 就乱码了

phpinfo（）中的gd部分

注释掉header('Content-type:image/png'); 就乱码了
这表示你的图片流中含有其他数据（你可截个图贴出来看看）
可能是有 BOM 头

解决了是空格用ctrl+shift+f 去了空格就可以了

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
