Opera & $PHP_SELF

[Anon]

I've got a problem using $PHP_SELF.
In a script I have a line like

echo "<a href='".$PHP_SELF."?a=".$b."'>";

While viewing the page with IE, ther's no problem - the name of the script is placed instead of PHP_SELF, but in Opera (5.12) PHP_SELF seems to be empty, and nothing in its place is echoed.

Does anyone have a key to the problem?
Thnx.

Since $PHP_SELF have nothing to do with the browser, I would think your error is that you are using $PHP_SELF in a function and haven't got the line:
global $PHP_SELF;

Try using the global statement or $GLOBALS['
PHP_SELF'] instead.

Nothing to do with the topic, but you should read some PHP manuals, etc.
There's no need to do:
echo "this is a variable".$PHP_SELF.", okay?";

You can insert everything in a quoted line:
echo "$PHP_SELF: gee, this sounds difficult";

Just pay some attention to arrays:
echo "This is ". $GLOBAL['PHP_SELF"].". So what?!";

got that?

Yes, I know. But there's another guy writing code with me, and he prefers writing double-quotes and put variables into lines, while i prefer single-quotes and concatenating strings with '.' . So the code is a little weird ;-)

Perhaps no need, but it is often easier to read the code if you use the "some ".$var." here" style, this is especially true when using syntax-highlighting editors (Jed, emacs etc.)

Gee, i never thought that some tips would create a whole "syntax" discussion thread. (i think i need to be sober next time).
