Hi
i hope that someone help me with that function.i have no idea what to do 🙁

while ($row = mysql_fetch_array($sql_result))
{
$smile_alt = trim($row["alt"]); // 🙂 , 🙁 , 😃 , 😛 , etc....
$smile_text = trim($row["smile"]); // smile1.gif, smile2.gif, etc....
$smile_image = smiles_dir . trim($row["image"]); // images/smile1.gif etc....
$smile_url = "<IMG SRC=\"" . $smile_image . "\" border=\"0\">";
$ret_text = i need some function that replace text smile ($smile_text) eg.
🙂 with link to image ($smile_url)
}

text smiles are saved in database in "smile" row, smiles image names are
saved as "image" row. eg.
"smile" "image" "alt"
🙂 smile1.gif smile

I tried preg_replace and str_replace but it not work for me in most cases i
got this error message:
Warning: Compilation failed: unmatched parentheses at offset 1 in ...on line
69
Warning: Compilation failed: missing ) at offset 2 in ... on line 69

This is what you're after:

http://www.php.net/manual/en/function.addslashes.php

You need to add slashes to the smilies.

addslashes escapes quotes and backslashes, this is not enough to get regex to work since in regex pattern a lot more sign have special meaning - ()[]{}...

therefore you need to escape these signs:

🙁 -> :(

(preg_quote can do this for you, but I'd do it by hand unless I was dealing with a "dynamic" patterns, e.g. from user input)

hope this helps,
