Try writing a c-program of 5 lines that will give you characters on
the standard output. It is hard to do it in another way, since usually
editors are "smart" and tend to hide the information you "don't want
to see". Here, compile this and run it:
#include <stdio.h>
int main()
{
int c;
while ( (c = getchar()) != EOF )
putchar(c);
return 0;
}
save it as x.c and compile it by
gcc -o x x.c
then run it as ./x < script.php (where script.php) is your php file
you have problems with.
if you see 2-3 characters on the screen before <?php then that is your
problem, which most probably is (faced it, like everyone else here,
probably)
Another problem that you might have is your php file being included by
another php file.
All of these problems are automatically avoided by using proper
templating systems. Think about smarty, for an example
(php.smarty.net)
