PHP Regexs (I presume) help needed

n0dice · 02-22-2006, 09:54 AM

Hey all. Basically what I'm trying to do is take a text string generated from form and take each individual alphanumeric character and replace it with the corrosponding image. So if 'cat' is typed in it displays '<img src="c.gif"><img src="a.gif"><img src="t.gif">. The images would be transparent gifs of the corrosponding letter from a specific font. Is this possible and how might i do it? Thanks.

Well you don't really need a regex here...
Basically you need to 'scan' your string one letter at a time - a simple loop will do the job nicely

PHP Code:

  <?php

 
$input_string=$_POST['your_text_field_name_here']; // => here put the name of the input field as defined in your HTML form

$string_length=strlen($input_string); // check length of input string

if ($string_length > 0 ) {

     for ($count = 0; $count < $string_length; ++$count) {

????: NamePros.com http://www.namepros.com/programming/170106-php-regexs-i-presume-help-needed.html
     echo '<img src="'.substr ($input_string, $count, 1 ).'.gif">';

     }

}

 
?>

very clever!

well done - have been looking for something like this for a long, long time, and just never thought to use substr. I was stuck trying to find a way to use explode!
