PHP image manipulation help

Ekim

Hi,

I am trying to get image manipulation to work in PHP, but I'm not very good at it and was wondering if someone here could hlpe me!

Here's the code I made up last night by hacking together a few scripts I found on the net. Basically I want to have a random string of words appear in this picture:

http://www.ruds.co.uk/mike/banner/random.gif

heres the code I am using at the moment

<?php
$textfile ="banner/who.txt";
$textfile1 = "banner/verbs.txt";
$textfile2 = "banner/objects.txt";

$who = file("$textfile");
$what = file("$textfile1");
$with = file("$textfile2");
$who1 = rand(0, sizeof($who)-1);
$what1 = rand(0, sizeof($what)-1);
$with1 = rand(0, sizeof($with)-1);
$string = "$who[$who1] $what[$what1] $with[$with1]";
$id = ImageCreateFromGif("banner/random.gif");
$yellow = ImageColorAllocate($id, 255, 255, 0);
$white = ImageColorAllocate($id, 255, 255, 255);
$black = ImageColorAllocate($id, 0, 0, 0);
ImageString($id, 4, 10, 20, strtoupper($string."!"), $black);
ImageGif($id,"./newmonkey.gif");
?>

Also I was unsure on how to actually call this code from within the page the image needs to be displayed on.

And if someone can think of a better way of creating the word I would be grateful to find out how cause I'm not very good and the textfile seemed like the easiest thing to do, although it can give some pretty poor results.

Many Thanks

Mike

P.S I am extremly new to PHP, so any help would be greatfully recieved!

Your code is OK, but I don't know how you wanna call it? Once a day? Or on every request? If you want to present every visitor a different string, try the following:
Place your code into a file - e.g. random.php or whatever - and change the last line to:

Header("Content-type: image/gif");
ImageGif($id);

This will return the randomly created image to the user's browser. Now, if you want to invoke it on your page, use the following:
<img src="random.php" border="0" />
Hope that helps

1) You need to update GD. You're using an older version that is using unlicensed GIF compression.
2) You need to output the image without the filename specification. This will make it output to the browser as the image, rather than saving it to a file. You can call it just as Natty_Dreadlock said.

A tip: use imagettftext to do TTF text on your image, rather than imagestring, which is a fixed-width font.
