I really don't understand, though, why you are doing things the way
you describe...
I only want one image file for each distinct letter, no repeats
because
I can't put two or more files with the same name
in the same dir. The images need to be drug around DHTML style and
reassembled into the correct word. Javascript
needs to be able to establish when the chars are in the correct order
so I need to have php feed it a formula to refer to.
Okay, now we are getting somewhere!
The easiest way to meet the unique filename requirement is to name
each file after its letter:
a.png
b.png
c.png
Of course, they only need to APPEAR that way to the browser and
Javascript.
In reality, you may not actually have a file named "a.png" at all.
For example, if your HTML is like this:
<img src="/drawchar.php/a.png" />
And you have a PHP script drawchar.php like this:
<?php
//EG: $path_info will be "/a.png",
//because that is what is in tha URL AFTER the PHP script name
$path_info = $_SERVER['PATH_INFO'];
//get JUST the one letter
$char = substr($path_info, 1, 1);
//Create the image:
$image = imagecreatetruecolor(40, 10);
//Boring colors, but works for now:
$white = imagecolorallocate($image, 255, 255, 255);
$black = imagecolorallocate($image, 0, 0, 0);
//make the background white:
imagefilledrectangle($image, 0, 0, 39, 9, $white);
//draw the character:
$font = 3; //Fonts can be 1 through 5
$x = 2;
$y = 38;
imagechar($image, $font, $x, $y, $char, $black);
//Find out how big the image is:
ob_start();
At this point, could you have an switch statement that checked the
extension that you sent in the url and make it run the corresponding
imagepng(), imagejpg(), and imagegif() ?
imagepng($image);
$image_raw = ob_get_contents();
ob_end_clean();
$image_length = strlen($image_raw);
//Send suitable headers:
and then here send the corresponding header too.
Just a thought about making it even more universal.
jl
header("Content-type: image/png");
header("Content-length: $image_length");
//Send the data:
echo $image_raw;
?>
You can now just pass the word 'dissatisfaction' around, and use PHP
or JavaScript to output individual images.
I'll do it in PHP:
<?php
$word = 'dissatisfaction';
for ($i = 0, $len = strlen($word); $i < $len; $i++){
$char = $word[$i]; //or use substr if you like
echo "<img src=\"/drawchar.php/$char.png\" />";
}
?>
I haven't run this code to test it, so there might be a typo, but it's
going to be MUCH easier to maintain than what you've got going...
