为什么 PHP 的 mime_content_type() 函数会将此 SVG 图像检测为 HTML? [英] Why does PHP’s mime_content_type() function detect this SVG image as HTML?

问题描述

我想生成 SVG 图像以外的上传图像的缩略图，所以我的代码(简化):

I want to generate thumbnails of uploaded images other than SVG images, so my code goes (simplified):

if (mime_content_type($uploaded) === 'image/svg+xml') {
    //
} else {
    createThumbs($uploaded);
}

然而，对于这个上传的图片，mime_content_type() 返回 text/html.为什么?我该如何解决这个问题?

However, for this uploaded image, mime_content_type() returns text/html. Why? And how can I fix this?

推荐答案

图像缺少 标签.在它前面加上 <?xml version="1.0" encoding="iso-8859-1"?> 行，它应该可以工作.

The image is missing <xml> tag. Prepend it with something like <?xml version="1.0" encoding="iso-8859-1"?> line and it should work.
