Works for me, PHP 5.1.4. Prehaps you have some kind of output buffering
enabled. Using the -n command line switch will disable your php.ini
which should stop anything like that.
The syntax error you are getting is caused by not entering any input.
Your line 23 becomes:
$returnval = eval("return();");
Return expects some value to be provided, hence the syntax error.
