如何为src生成一个php图像

Question

I would like to use:

src="my_generated_image_from_php.jpg"

instead of

src="my_php_image.php"

How do I do it?

my_php_image.php like:

<?php
     ......
     Header('Content-type: image/png');
     imagepng($im2);
     imagedestroy($im2);
     ......     
?> 

Answer 1

You'll need to send an image header along with the image binary in your my_php_image.php file like so:

header("Content-Type: image/jpeg");
echo file_get_contents("my_generated_image_from_php.jpeg");

Obviously, you'll need to make sure the relative path of the image is correct for it to work. Otherwise, just use an absolute path from the root directory.

If you do this, you'll be able to use the second option as the image source.
