Use a php function to fill an html image tag and show the image

So I've been asked to do this. I have an image expressed as an array and I've tried pretty much every way I can think of to make the html tag accept the members of the array but nothing works excepts for super simple stuff I am sure the instructor is not interested in seeing. I've tried the exotic php functions (array_combine for example) and foreach/for loops. I got nothing. Does anyone have an idea about how to make this work. I never ask unless I've spent a few hours trying. I am still too much of a newbie. My code is below. I know it sucks.

<html lang="en">
  <meta charset="utf-8">

  <title>You Need Arrays</title>

  <link rel="stylesheet" href="assignment4.css">



$fish = array("apipefish.jpg", "Seattle Aquarium Pipefish",  "342", "640");


<img src="$fish[0]", title="$fish[1]", height="$fish[2]", width="$fish[3]" />;

It's been like two years since I used PHP, so I don't have the most elegant solution. The problem is that you're trying to reference the data inside your array, but the browser only sees the img tag and none of the data written in PHP. You need to escape that call to the img tag for PHP to write that out to the browser. One possible way to do that is using string concatenation within the <?php ... ?> call. Like this,

        echo '<img src="' . $fish[0] . '" title="' . $fish[1] . '" height="' . $fish[2] . '" width="' . $fish[3] . '" />';

I hope that helps. Again, I haven't used PHP in awhile.


Sorry, I would probably use a formatted string over string concatenation because it's easier to read and more convenient. You can do that as follows:

        printf('<img src="%s" title="%s" height="%s" width="%s" />', $fish[0], $fish[1], $fish[2], $fish[3]);

And that should give you the same result.

Hey it works. I'll wait it out a bit (because I don't know whether or not she wants something fancier) but at least I have something that shows the image.
