How can I limit the amount of emoticons(smilies) that can be posted in (Page 2 of 2)

function check_smilies($text)
{
    global $smiley_text;

    $text = ' '.$text.' ';

    $num_smilies = count($smiley_text);
        
    $num_message_smilies = 0;

    for ($i = 0; $i < $num_smilies; ++$i)
    {
        $num_message_smilies = $num_message_smilies + substr_count($smiley_text[$i]);
    }
    
    return $num_message_smilies;
}

function check_smilies($text)
{
    global $smiley_text;

    $text = ' '.$text.' ';

    $num_smilies = count($smiley_text);
        
    $num_message_smilies = 0;

    for ($i = 0; $i < $num_smilies; ++$i)
    {
        $num_message_smilies = $num_message_smilies + substr_count($text, $smiley_text[$i]);
    }
    
    return $num_message_smilies;
}
