Well I'm not too good at php but I've seen this problem loads. T_string refers to the $ whatever thing (see I don't know what even thats called).

CODE

$user = mysql_fetch_array($SearchQRY);

I believe that is your problem but unless you tell us where line 195 is we can't do much, without tediously checking the whole script :/. Hope thats helped a little if not then ahh well lol.

Line 195 would be:

CODE

echo('<fieldset><legend>'.$user[username].''s Profile</legend>

You forgot to escape the single quote before the letter S. It should be:

CODE

echo('<fieldset><legend>'.$user[username].'\'s Profile</legend>

Here's the problem - sorry for lack of "technical" words but they've escaped me for the moment. First - you don't need brackets around echo functions.

This does the same thing, and the first method is most preferred too as it's easier to read.
echo "text";
echo ("text");

So, to what's producing the error.

CODE

echo('<fieldset><legend>'.$user[username].''s Profile</legend>

What you've tried to do is put in a ' but in your current setting that ends the string. There's two ways to do this.

One - put in a slash \ right before the second '. The \ makes the second ' as escaped. What this means is that php sees it as text, and not part of the syntax. The other is to use 'rabbit ears' aka ". Compare these.

CODE

echo('<fieldset><legend>'.$user[username].'\'s Profile</legend>
Username: '.$user[username].'<br />
Email: '.$user[email].'<br />
Real Name: '.$user[realname].'<br />
Website: '.$user[website].'<br />
Location: '.$user[location].'
</fieldset>');

echo "<fieldset><legend>{$user[username]}'s Profile</legend>
Username: {$user[username]}<br />
Email: {$user[email]}<br />
Real Name: {$user[realname]}<br />
Website: {$user[website]}<br />
Location: {$user[location]}
</fieldset>";

Yes, there's significant difference between ' and ". Either can be used to start a string and end a string. The ending one has to be the same as the starting one. " is more special then your standard text - and here's why.

Minus the last two, all of these are valid and will echo This is test text.

CODE

$string = "test";

echo "This is $string test"; //Check Note
echo 'This is '.$string.' test';
echo "This is {$string} test";

echo 'This is $string test"; // outputs This is $string test
echo 'This is {$string} test"; // outputs This is {$string} test

Note This method can only be used with simple variables. They cannot be used with arrays where you can select the position. This is what the {} are for. For Example.

CODE

echo "This is {'te'.'st'} text";

Note the addition taking place? You can do almost anything inside that bracket.

To sum up - You can use "" and ''. You can use them inside each other without problems. "t'es't" (outputs t'es't). You can't do this - 't'es't' (outputs error). However, you can escape them to do this. 't\'es\'t' (outputs t'es't).

QUOTE

Well I'm not too good at php but I've seen this problem loads. T_string refers to the $ whatever thing (see I don't know what even thats called).

That $ tells php that the string after it is in fact a variable.

test //string
$test //varible
