[SOLVED] Preg_replace problem

[helraizer]

Hey folks and folksesses,

 

I have written some code to get emoticons onto my image based shoutbox but there is quite a large bug, as there is with any code in the early stages, and I need your help to narrow it down for me.

 

The idea is that the script pulls data from the database - username, colour, font and shout to print '[username] shout' onto the image. This part of the code all works perfectly. Then it looks through each line at a time to see if there is either , , or in the shout, if there is it finds the position of the string it's at, uses this data * a number to get the emote to the correct place on the image. After it has found that result and merged the emoticon onto the shoutbox, it deletes the , , or from that shout, depending on which was used from the shout so that there is no overlapping of text and image.

 

This works fine for the - the test post "Yay!! " gives this result (top line)

 

 

Whereas the post "Yay!! " gives the result

 

 

^ it deletes the entire username and shout from the image and merges the emoticon into place.

 

showimage_a.php

 

<?php
        $name = "[" . htmlspecialchars_decode($row['username']) . "] "; //it works - returns username
        $font = $row['font']; //it works - renders the colour
        $color = $row['color']; //it works - changes the font
        $line = htmlspecialchars_decode($row['comment']); //it works, posts the shout


        if ($name == "[] ")
        {
            $name = "";

            $line = $name . $line;
        }
        else

Any ideas?

try using backslashes like in your yay code 

 

$line =  preg_replace('/:)/', "", $line);

Wow, your first response was the charm.. I changed preg_replace to str_replace and now it works perfectly. xD

 

It always seems to be the simplest answers.

 

Thank you very much for that!
