Php code help regarding images - php

Question

So I have this php script which generates random text on an image.
The text file is a different php file and the image file is a seperate php file.
The image.php file calls this text.php to select a random text.
This version works fine, but is it possible to generate a random image on my existing image file?
I have included the current versions of my code.
This is text.php:
<?php
$t[] = 'Sample text 1 ';
$t[] = 'Sample text 2';
shuffle($t);
?>
This is image.php:
<?php
require_once 'text.php';
$text = wordwrap($t[0], 31, "\n", true); //text
$image = imagecreatefromjpeg('img_empty.jpg'); //background image
?>
Any suggestions are welcome.

Answer 1

Your question is bit unclear.. You don't want text.php then you can directly use it's code in image.php as shown below.
image.php
<?php
$t[] = 'Sample text 1 ';
$t[] = 'Sample text 2';
shuffle($t);
$text = wordwrap($t[0], 31, "\n", true); //text
$image = imagecreatefromjpeg('img_empty.jpg'); //background image

Answer 2

Several options here
Have several background-images saved and select one randomly among them.
Use GD and Image Functions to draw on your existing image before outputting it (look at imageline() for drawing lines for example).
Use GD's imagecreatetruecolor() to create the image, to even get random width/height.

Answer 3

if you want to create an image with random text this will do it
image.php
require_once 'text.php';
header("Content-type: image/png");
$string = wordwrap($t[0], 31, "\n", true); //text
$font = 2;
$width = imagefontwidth($font) * strlen($string);
$height = imagefontheight($font);
$image = imagecreatetruecolor ($width,$height);
$white = imagecolorallocate ($image,255,255,255);
$black = imagecolorallocate ($image,0,0,0);
imagefill($image,0,0,$white);
imagestring ($image,$font,0,0,$string,$black);
imagepng ($image);
imagedestroy($image);
UPDATED CODE TO YOUR RESPONSE:
if you want to get your random text over a specific image
require_once 'text.php';
header("Content-type: image/png");
$string = wordwrap($t[0], 31, "\n", true); //text
$image = ImageCreateFromJPEG("img_empty.jpg");
//Defining color. Making the color of text as red (#FFF) as 255,000,000
$color = imagecolorallocate($image , 255, 000, 000); //
//put string over image with $color as color
imagestring($image,5,126,22,$string,$color);
imagejpeg($image,NULL,100);
The above code will put a red color random text over your specified image.this works for me. Also try changing the colors defined in imagecolorallocate() function.
