Display both text +multiple images from imagepng on 1 page

ExpertAlmost

I use PHP to calculate some lines of data and then create four images using imagepng. I can display one image. Or display the text. But I can not do both on the same page. And I want to display the text, go down a few blank lines and then display the four images, from left to right, on the same page. The images are not stored in a file but created dynamically.

Right now, I have one index.php page to display the text and another index.php page to display one image. Two rowboats, one oar...

How do I show text and four images on one html page inside my php code? Or is it outside the php code?

I am just learning PHP and know NOTHING about HTML so clear examples would be very helpful.

Thank you so much!

put the image drawing php code into another php file from index.php, for example: picture.php

and you can generate these pictures like this:
in html or your index.php file:
<img src="picture.php?image_id=1" border="0">
<img src="picture.php?image_id=2" border="0">
<img src="picture.php?image_id=3" border="0">
<img src="picture.php?image_id=4" border="0">

and in picture.php lets chose the $_GET["image_id"] value from a database, or an array, for
the texts you like to display.
if you don't know how to select that from a database, we could make you an example around that.

Thank you very much for your help! That makes sense for sure. I will create a new php file for creating images with my four calls to imagepng() in it.

But I am not sure about the $_GET call. Isn't that a global server variable or something? I did not know I was using those. What is the image_id=1" part of the tag mean? Right now I just have:

header("Content-Type: image/png");
imagepng($Img1);
imagepng($Img2);
imagepng($Img3);
imagepng($Img4);

to create my four images. Though I only seem to be able to output the first one.

Thank you again for sharing your experience!

To use the get variable in the above example,try this.

<?
header("Content-Type: image/png");
switch( $_GET['image_id'] ) {
    case 1: imagepng($Img1); break;
    case 2: imagepng($Img2); break;
    case 3: imagepng($Img3); break;
    case 4: imagepng($Img4); break;
    default: imagepng( $error );
}?>
