<?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);?>
Copy after login




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
