PHP Parse error

[BWGames]

Can someone tell me whats up with this code please?

$update_query = "UPDATE users SET creditremaining = creditremaining - " .
$_REQUEST['MsgCount'] . "WHERE mobilenumber = " . $_REQUEST['From'] . "";

where creditremaining is a MySQL table field, and $_REQUEST['XXX'] is a
HTTP GET variable.

Thanks,

Ben

You should have copied the PHP error you get: I get none. In any case,
please note there isn't a space before WHERE so the database query won't
work.

Also, you should use mysql_escape_st ring() because you never know what
$_REQUEST will contain.

'cept for the missing space before "WHERE" there is no problem. Maybe
you missed the final semicolon in the line before that?
In most cases parsing errors are caused by unclosed brackets or missing
semi-colons one row before the one deemed faulty in the error message.

That's funny, as I get:

Parse error: parse error in /www/page.php on line 16, where line 16 is:

$update_query = "UPDATE users SET creditremaining = creditremaining - " .
$_REQUEST['MsgCount'] . " WHERE mobilenumber = " . $_REQUEST['From'] . "";

The line after that is
If ($update_result = mysql_query($up date_query)) {

I can't see aproblem with either of the lines either..

Anyone?

Thanks for the help so far :)

(bad form to reply to my own post, but sorry!)

Ooops sorry!

The problem was a missing ) in the preceding IF statement.

Sorry all!

In addition to the other comments, I'm sure your 'mobilenumber' field
oughtn't be numeric (you won't be carrying out any math on it, and you'll
lose leading zeroes) - it should be encased in single quotes if it's a
string.

FWIW, I cut&pasted that line into my test file and syntactically, it works
fine.

It's *very* important to realize that a parser can't detect the exact point
at which an error occurs. All it can do is detect the point where its
input stops making sense according to the language's grammar; this is
almost always going to occur quite a ways *after* the actual mistake.

For example, if you leave off the closing parenthesis on an if condition,
the parser will try to read the next statement as if it was still part of
the if condition. It won't be able to detect an error until it runs across
something that can't legally occur inside an if condition, and that may be
well into the next statement, or even the statement after it.

That was my point. Usually a missing (closing) bracket or semicolon does
exactly that, eg:

if (isset($a) {
// some code
}

(missing bracket after "isset")

or

$bar = 10 * 5 + 3
$foo = $bar;

(missing semicolon in the first row)

In the second example the error will occur in the row AFTER the one
missing the bracket.
