call to undefined function -- fwrite()

[mstembri]

	$name = "me";
	$fileopened = fopen ("test.txt", "a+");
	$fwrite ($fileopened, $name"); 
	fclose ($fileopened);

Any idea on why this script would produce a 'call to undefined function on line 3' errror? (line three being the fwrite line)

Thanks.

(ps, I've used fputs() and it produced the same error)

I just tried the same script on a different server, still getting the call to undefined function error. Both servers use php4.

lose the $ character

$fwrite ($fileopened, $name");

shoud be

fwrite ($fileopened, $name");

Yup - interestingly enough the reason you got a "undefined function" error rather than a standard syntax error is that the line:

$fwrite ($fileopened, $name);

Could actually mean something. This is due to PHP allowing you to use variable function names. The following code is perfectly legal:

$string = "fwrite";
$string ($fileopened, $name);

The above is exactly the same as this:

$string ($fileopened, $name);

It's an interesting feature this - I'm sure it could be useful although I've never felt it necessary to use it.
