working with 2 arrays

[twopeak]

I'm not really good with arrays, but I'll explain:

my intention is to have two arrays, search for the values of the first array in a message, and change it with the value of the second array

<? php
$input = array("🙂", "🙁", ":p");
$output = array("happy.gif", "nothappy.gif", tongue.gif");

for each($input) {
$thing = $input[$key];
$message = eregi_replace("$input[$key]", "$output[$thing]",$message);
}

?>

What I think it does:

first it takes the first value of the $input array
then it save "1" into $thing
then it will replace the first one of the $input array with the first one of
the $output array
and so on for the second and third one.....

any ideas how to make this work?

i think this works a lot easier

$arr=array("/:\\)/i"=>"<img src=happy.gif>",
"/\\:\\(/i"=>"<img src=nothappy.gif>",
"/\\:_p/i"=>"<img src=tongue.gif>");
// the forum makes the tongue gif, so take out the _ in :_p

$out=preg_replace(array_keys($arr),array_values($arr),$intext);

if that doesnt work, then the forum fuckedup the regx 🙂

Thanks!
it works for 99%!!!

My only small problem is that when I do this

I change the msn images into the msn images on my guestbook
so I have my array like this:
$prentjes=array('~(y)~i'=>'<img src=\"images/thumbs_up.gif\" alt=\"Thumbs up\">',
'~(n)~i'=>'<img src=\"images/thumbs_down.gif\" alt=\"Thumbs down\">',
'~(b)~i'=>'<img src=\"images/beer_yum.gif\" alt=\"Beer mug\">',
...........

some of these will have as output (*IMAGE
instead of just the IMAGE!

any ideas on how to correct this?

my first guess would have been that it takes the backslash as a part of the modifier, but I just read the manual, and found out it's not this...

EDIT

some time later, alot of pages of the php manual and some other tutorials, this newbie is getting nervous...

Isn't there a better way to do this?
hell:
'~(:))~i'=>'<img src=\"images/regular_smile.gif\" alt=\"Smiley\">',
that's the line for a regular smiley...
Isn't there a way to do something like this:

$smiley = "🙂";
'~$smiley~i'=>'<img src=\"images/regular_smile.gif\" alt=\"Smiley\">',*/

cose the other way is just making me crazy!
