Ask questions. Php uses imagejpeg (Image Display) to show one image. Why do I still show one image?

Only one image is displayed on the webpage.

Only one image is displayed on the webpage.

Only one image is displayed on the webpage.

Imagejpeg ($ im, "../images/image001.jpg"); // save it to an address

And then reference it twice on the webpage.

Under Research
Copied code // Create a blank key image and add some text
$ Im = imagecreatetruecolor (120, 20 );
$ Text_color = imagecolorallocate ($ im, 233, 14, 91 );
Imagestring ($ im, 1, 5, 5, 'a Simple Text string', $ text_color );

// Set the content type header. In this example, the header is image/jpeg.
Header ('content-Type: image/jpeg ');

// Output image
Imagejpeg ($ im );
Echo 1111111111111111111111111;
Echo "fffffffffasdffffffffffffffff ";
$ Im = imagecreatetruecolor (120, 20 );
$ Text_color = imagecolorallocate ($ im, 233, 14, 91 );
Imagestring ($ im, 1, 5, 5, 'adddddddddddddddddddd ', $ text_color );

Imagejpeg ($ im );

The effect is fruitless

Therefore, it is concluded that php does output two images, but there is a header ('content-Type: image/jpeg ');
Tell the browser that this is an image. The browser gets only one image. You can try to remove the hearder

Result

To view multiple images, use imagejpeg ($ im, "path"). Save the image and use it as the tag output.

Another way is to use the verification code to load a php page in p or img.
