Help Debug for hangman game

Hi everyone. I'm currently trying to make a little hangman game just for the
heck of it, and I have everything finished except for a scoreboard (havent
even tried to tackle that one yet; shouldn't be too hard though), except for
one little problem I'm having. Basically when the script that checks to see
if a letter is in the word runs, it will take all instances of a guessed
letter and put them at the start of the first instance. For example is the
word was xerox and someone guessed the letter 'x', it would be printed as
xx_ _ _ . I'll show you the code, and if you can help me figure out why this
isnt working right, I would be very happy.



$j=strlen($canswer); //$canswer is the answer as you might have guessed
for($i=0;$i<$j;$i++){
if((substr($canswer,$i,1))==$letguess){

$blanks=substr_replace($blanks,$letguess,$i); /*blanks is a variable
coming from an fread of blanks.txt which starts as a series of 0's (as
many as there are letters in the answer) that are supposed to
get swapped out with guessed letters*/
$ip=getenv("REMOTE_ADDR");
$thing=$ip."blanks.txt";
$handle=fopen($thing,"r+");
fwrite($handle,$blanks);
fclose($handle);




$right=1;

}
}


Naturally there's more to the whole thing, but I think this is the part that
is giving the problem, since i checked the blanks text file, and its not the
part of code that outputs letters and spaces. If I haven't provided enough
information, just ask me. Also if you want to play the game to see what I'm
talking about, you can do it here if my server is on:

*Sigh* Ill probably figure out whats wrong 5 minutes after making this post.
Oh well...

Hmmm, to help you see the problem, I'll set it so that the word is always
xerox.

Try this

$blanks=substr_replace($blanks,$letguess,$i,1); /*blanks is a variable

Oh, you are a saint! I didn't even know that substr_replace had that fourth
paramater! Thanks again, I'll repost the link in a few days after I finish
the scoreboard feature, along with the source code (it's sloppy, very
sloppy).
