Another BB code problem

[faifas]

Hey all,
I've made myself a bb code function for bb codes and came up with a problem:

i wanted to add smilie :/ but it ruins url code
example:
{url=http://www.google.com}Google!{/url}

str replace replaces

:/ into a smilie and google.com comes vanished O_o
Any idea how to solve this?

Can you post the function you use to parse your bb-code?

function bb_code($string)
{

// Encoding string with HTML special characters

$string = htmlspecialchars($string);

// all <headings>

$string = str_replace("[h1]", "<h1>", $string);
$string = str_replace("[h2]", "<h2>", $string);
$string = str_replace("[h3]", "<h3>", $string);
$string = str_replace("[h3]", "<h3>", $string);
$string = str_replace("[h4]", "<h4>", $string);
$string = str_replace("[h5]", "<h5>", $string);

$string = str_replace("[/h1]", "</h1>", $string);
$string = str_replace("[/h2]", "</h2>", $string);
$string = str_replace("[/h3]", "</h3>", $string);
$string = str_replace("[/h3]", "</h3>", $string);
$string = str_replace("[/h4]", "</h4>", $string);

// Adding line breaks to the string
