php header 图片 格式,PHP输出图片的header格式 header中Content-type 的种类

PHP在输出图片格式时，需要加上header("content-type:image/jpeg");

Content-type:image/jpeg 的意思是告诉浏览器这个文件是个图片不是html,不能再定义为html文件的Title 所以不能直接在地址栏输入地址去访问该页，如果不加这段，IE下或许可以正常显示，但其他浏览器均显示乱码。 如果要有title, 就写html文件,在程序输出头header("Content-type:text/html");默认这个是可以不用写的。
