PHP - call a function from a img src [duplicate]

Answer 1

PHP is server side; It can generate either a base64_encoded image result which can be placed as an image, or you can point to a php script that will generate an image. But, regarding client side, it won't work.

So, you could do the following:

// the browser will make a call to your generator to render an image back
echo '<img src="myimagegenerator.php" />';

// src will be something like "data:image/png;base64,..."
echo '<img src="'.generateImage().'" />';

Answer 2

No.

However, you can use the URL "thispage.php?makeimage=1" and call the function and output an image if $_GET['makeimage'] contains 1.

Answer 3

In HTML5 you can put the base64 encoded image source in an image tag. You will just need a function to return that.

function getImage($file){
      return 'data:image/gif;base64,' . base64_encode(file_get_contents($file));
}

Your img tag:

<img src="<? echo getImage('path-to-image.gif'); ?>" />
