I'm currently using this to replace every letter with an image. However sometimes it doesn't work correctly.

Basically it would replace the word "hia" with "<img src='images/h.png'/><img src='images/i.png'/><<img src='images/i.png'/>mg src='images/<<img src='images/h.png'/>mg src='images/i.png'/>.png'/>"

 

When it gets to the letter i it seems to replace it with <img src='images/i.png'/>

Please help.

~Thanks Lars!

u shoudl do it in one call like so

 

$search = array('a','b','c');

$replace = array("<img src='a.png'>","<img src='b.png'>","img src='c.png'");

 

$str = str_replace($search, $replace, $string);

 

 

also u may want to look at function str_ireplace which is case insensitive

[Lars!]

It does the same thing :S

dont forget, str_replace works on the entire source string each time so you need to wrap your letters in something that will not be in the replaced string

[Lars!]

[jl5501]

if you can arrange it, so your original letters are like '{a}' instead of just 'a' then you can get this to work

 

with your way the i in images would itself get replaced, etc.

im lost lol

damn what about using regexp try this:

 

$result = preg_replace('/([a-z])/i', "<img src='images/\\1.png'>", $string);

 

in case u have different letter pictures for lower and upper chars use this

$result = preg_replace('/([a-zA-Z])/', "<img src='images/\\1.png'>", $string);

[jl5501]

ok a question here, which may help resolve this.

 

Do the letters you wish to replace form part of words, or do they have space either side of them?

Came up with a solution:

 

function BText($str)
{
    $new = '';

    for($i = 0; $i < strlen($str); $i++)
    {
      if (ctype_alpha($str[$i]))
      {
        $new .= '<img src="images/' . strtolower($str[$i]) . '" />';
      }
      else
      {
        $new .= $str[$i];
      }
    }

  return $new;

}

$str = 'hia, pal!';
$str = BText($str);

echo $str;

 

OUTPUT SOURCE

<img src="images/h" /><img src="images/i" /><imgsrc="images/a" />, <img src="images/p" /><imgsrc="images/a" /><img src="images/l" />!
