Replacing text with images using PHP

BlazerRotare

Hello. I am trying to convert text into images using this script.

I will be using it for the headers on my site. I wanted to use this method so I could in theory type in anything for the header and each character would be replaced with the location of an image.

For example;

becomes;

L.gif o.gif g.gif i.gif n.gif

Upon running this script I found out that it does not only change the letter in the text but it changes all of the characters in the image tags like so: Link here

I was wondering if there was a way to modify the script so that only the L, o, g, i, n, was changed. You can see the script below. Any comments are much appreciated and if anyone has a beter method of how to do this then I would be more than happy to hear them out.

<?php

//  Array.
$header_text = array(
  'l' => "<img src='images/text/d.gif'>",
  'o' => "<img src='images/text/d.gif'>",
  'g' => "<img src='images/text/d.gif'>",
  'i' => "<img src='images/text/d.gif'>",
  'n' => "<img src='images/text/n.gif'>"
);


//   text 
$text = 'login'; 


echo convert_header_text( $text ); 


function convert_header_text( $t ) 
{ 
  $search = array_keys( $GLOBALS['header_text'] );
  $t = str_replace( $search, $GLOBALS['header_text'], $t );
  return $t;
}
?>

Thanks in advance.

don't know if i understood what you're trying to do ....
why don't you just replace 'Login' with the image(s) that you want to display ??

I will be adding files and articles to the database (literally hundreads) so it will be easier if I can input the title via mysql in text and then get it to appear on the page in image form without having to create loads of images, just ones or each letter of the alphabet and 0-9.

I think you will undestand now.
Sorry for not explaining it well enough. 😉

don't know if this is what you're looking for :

for ($letter='a';$letter<'z';$letter++)
	strreplace($letter,$yourString,'<img src=images/'.$letter.'.jpg>')

... for numbers you do smth similar

Getting there, but the problem is that after the first replacement, $yourString contains a lot more characters that are actually html. So the next time through, the 'i' in '<img' might get replaced - have a look at the amusing link in the original post and work out what has happened!

This will do it:

<?php
$letters = array();
$string= "login";
for($i=0; $i < strlen($string); $i++)
{
	$letters[] = $string[$i];
}
$output = '';
foreach ($letters as $key=>$value)
{
	$output .= '<img src=images/'.$value.'.jpg>';
}
echo $output;
?>

Is there a way to do this differently?

I would like to build a script that would allow me to accept text in a form then convert it into an image, while also giving the option of several different font styles and colors.

Say if I had 20 different font styles and 20 different colors for 26 lowercase letters and 26 uppercase letters. That would mean loading over 20,000 images. (if my math is correct)

Hi,

Gio's text maker doing this with any TTF font and you not need anything.
