What On Earth Is This Outlandish Error ?

Question

UI -3 Junior Poster

7 Years Ago

Programming Buddies,

Here's my latest script. It is a member reg-login script.
It registers you and gets you to activate your account confirming your email and then auto logs you into your account. It uses cookies to remember your user details. It was working fine until I added the feature for you to make posts to your friends or the public.
I get error:

PHP Parse error: syntax error, unexpected '"', expecting '-' or identifier (T_STRING) or variable (T_VARIABLE) or number (T_NUM_STRING) in /home/sn/public_html/sn/home.php on line 168

On many lines, I changed from:

$query = "SELECT * FROM users WHERE Username = '".$user."'";

to:

$query = "SELECT * FROM users WHERE Username = '$user';

but no luck in getting rid of the error. You will see line 168 doesn't have any ".
I use notepad++. Error mssg seems irrelevant.

And so, looking at the error and my script, what do you think the problem is ? Best to c
heck my code on your wamp/xampp to really understand the problem.

Thank You!

PPS - Script in next post.

Hi,

in this case the error message is very descriptive:

PHP Parse error: syntax error, unexpected '"', expecting '-' or identifier (T_STRING) or variable (T_VARIABLE) or number (T_NUM_STRING) in /home/sn/public_html/sn/home.php on line 168

It points to a specific file and line of the code. If you don't find the error in that line then search above. On line 133 of home.php there is a backtick:

exit();` // <-- remove this

If you want to learn PHP, learn to reproduce bugs: isolate the code that generates the error and try to get the same error message:

<?php

print 'hello';`
print 'world';

Generates:

PHP Parse error: syntax error, unexpected end of file, expecting '`' in /tmp/a.php on line 5

Also the backtick operator as a specific meaning in PHP as it's an alias of shell_exec(), you can run a command like this:

$arg  = array_key_exists(1, $argv) ? escapeshellarg($argv[1]) : '';
print `find . -type f -iname "$arg" 2> /dev/null`;

> php a.php *.jpg

More info: http://php.net/manual/en/language.operators.execution.php
The comment part of the manual, sometimes, is very useful.

You're welcome! Look at lines 179 and 187. In the first case you have to close the PHP tag ?>, in the second case you have:

//Display iFrame.?>

Here the closing tag is hidden by the comment //.

Thank you cereal for replying!
I now feel like having a cereal. Shreddies or Weetabix! Lol!

Anyway, my real problem was at line 129. Fixed that now as there was an
`
after exit ();.

However, I now get error:

"PHP Parse error: syntax error, unexpected end of file in /home/sn/public_html/sn/home.php on line 194".

My code is this:

homepage.php

<title>
$user Home Page

<body background=".png">

    header("location:login.php");
