Parse error: syntax error, unexpected T_VARIABLE

[Brigitte Smith]

I'm trying to make an image map and when I click on any part of it now it gives "Parse error: syntax error, unexpected T_VARIABLE in /usr/data2/hosted/angelauset/IMGMAPONE/map.php on line 11"

<?PHP

PHP requires that expressions end with a semi-colon.

// Bad code - notice: no semi-colon.
$name = 'Mark'
$age  = 19
 
// Good code - with semi-colon.
$name = 'Mark';
$age  = 19;
 

Mark.

@Markus
I added a semi-colon to the end of line 11 but I'm still getting that same error
EDIT: Now I'm getting the same error on line 15.

To quote Markus: "PHP requires that expressions end with a semi-colon."

EVERY EPRESSION

[Brigitte Smith]

@zorgi
What exactly constitutes an expression? How do I know where to put semi-colons? There IS a semi-colon in the line where it says that there is an error.

[zorgi]

What are expressions!?

You should learn those basics. Here is the link that will explain expressions AND here is another interesting link for you

P.S. Check the line before :)

[Brigitte Smith]

@zorgi
Ya, I think it's pretty obvious I just need an interchangable code where I can alter the rectangle numbers and never have to write one again. I'm terrible at coding even HTML. The link you sent made my head spin. >.< Thank you for the assistance though. Every time I fix one error more come up.

[Brigitte Smith]

Now I'm getting "Notice: Undefined offset: 1 in C:\Program Files (x86)\EasyPHP-5.3.2i\www\map.php on line 33". Adding a ; didn't fix it. I looked it up, but I have no idea what the people are talking about when they're telling other people how to fix this error.

That error is telling you that index 1 does not exist in the $x_and_y array.

// Consider:
$array = array(0 => 'Mark');
print $array[1];
// Doing this causes a warning because that offset (1) does not exist.
 

What does the output of

$x_and_y = explode(',', $x_and_y);
var_dump($x_and_y);
 

reveal?

[Brigitte Smith]

@Markus
I have no idea what you just asked.

[TheServant]

First of all, adding the semi-colon did fix the original problem, and after that, another problem was shown. Your latest error is completely different from the first.

Check $x_and_y. "offset is undefined" means that the requested array key has not been set. If your error is in fact on line 33, then it means the array $x_and_y, does not have a key of '1': $x_and_y[1]
Echo your $_SERVER["QUERY_STRING"] and check that it has what you want.

(^ what Markus said)

[Brigitte Smith]

@TheServant
I still don't understand. What part of the code do I change? And what do I change it to? If "$inY = $x_and_y[1];" is wrong, what is right?
Edit: Ok, I fixed that line, but now I get "Parse error: syntax error, unexpected T_UNSET in C:\Program Files (x86)\EasyPHP-5.3.2i\www\map.php on line 34"
Edit: I replaced that line with

$x_and_y = null;
echo $x_and_y; 

and that error went away.
Now I have "Notice: Undefined variable: inY in C:\Program Files (x86)\EasyPHP-5.3.2i\www\map.php on line 38". Since I removed the inY part of the code, what do I put there?

[TheServant]

We're not saying to get rid of it. What we're saying is:

$x_and_y = $_SERVER["QUERY_STRING"];
$x_and_y = explode(",",$x_and_y);

Is not returning an array with two values. It is only returning a single value, which I am going to guess is because $_SERVER["QUERY_STRING"] does not contain a comma, which is what you're using for your explode. The rest is OK, you just need to get that explode line working.
