[RESOLVED] Unexpected T String error

[JKH]

Hi,
I'm new to coding and downloaded an old game script to try to teach myself and have been watching and taking lessons from codeschool, I can not with my knowledge work out what is wrong with this line:

    echo '« <a href="http://'.$_SERVER['PHP_SELF'].'?act=add" target="_blank">Add Game</a> » 

I recieve this error message: Parse error: syntax error, unexpected T_STRING, expecting ',' or ';' in /home/****/public_html/5050.php on line 86.

Here is the full code, could you please not just tell me what to do but EXPLAIN it so I learn from my mistakes Thanks so much!

<?php
require_once("globals.php");

        $exe = mysql_query($SQL);
        $fetch = mysql_fetch_array($exe);

I am also having another T-String error where it does not define what is wrong just the line. this page reads

http://codepad.org/VUrwBmWC

It refers me to this line

$query3=sprintf("SELECT `uid` FROM `session_chat` WHERE `uid`='%d'", $ir['userid']); 

This may sound stupid but does anyone have a resource link handy that will explain what these error codes mean? Sorry for taking up so much time, thanks
JKH

What are you using for an editor? I ask because the syntax highlighting breaks for no apparent reason in your _view_games() function. And if I copy it and check for syntax errors myself I don't find any except for those due to the spurious *s that start at line 103 (the body of the _challenge() function), which also suggest that your editor is mangling your code.

(FWIW, T_STRING is a pretty generic token; see tokens.)

[JKH]

Thanks for the prompt reply I am using notepad++ as my editor. The first time I saw the *s was upon copying it here.

[JKH]

Also thanks for the link on tokens I'll read up on it tonight

[JKH]

I went ahead and removed what looked like blank spaces, but was *** when view in hexidecimal view, but i still recieve the same error, any suggestion on what I can do to remove the error? Thanks

I found what was causing the error, now the only error I am receiving is "PHP Syntax Check: Parse error: syntax error, unexpected T_ECHO in your code on line 112"

Looks like those dreaded asterisks again:

                    }************ 
                echo '</td>
                </tr>';

The asterisks usually indicate some extended ASCII or odd Unicode character that the vBulletin software didn't like.

For example, between the following quotes, I'll place four non-breaking spaces (U+00A0, " " as an HTML entity, Alt+0160 on the number pad): "****".
