curiosity; FPUTS inside a function

[Anon]

here's a strange one... when i use this code:

$datenow = date( "d-m-y" );
$timenow = date( "H:i" );
$f = fopen ("bookfile.csv", "aw");
fwrite ($f, "$REMOTE_ADDR, $datenow, $timenow, $myname, $myemail\n");
fclose ($f);

it writes to the csv file just fine; but if i put it inside a function:

function WriteFile() {
echo $myemail;
$datenow = date( "d-m-y" );
$timenow = date( "H:i" );
$f = fopen ("bookfile.csv", "aw");
fwrite ($f, "$REMOTE_ADDR, $datenow, $timenow, $myname, $myemail\n");
fclose ($f);
echo $myemail;
}
WriteFile();

it doesn't record the variables. any ideas?

oh, further to this: the "echo $myemail;" are just to test if the variables have been passed; seems as if they don't, as neither occurence writes to the screen when inside the function.

Hmmm.... I assume register_globals is off?

If it is on, then you have to use global to register the variables inside the function:

function WriteFile() {
global $myemail, $myname;

echo $myemail;
$datenow = date( "d-m-y" );
$timenow = date( "H:i" );
$f = fopen ("bookfile.csv", "aw");
fwrite ($f, "$REMOTE_ADDR, $datenow, $timenow, $myname, $myemail\n");
fclose ($f);
echo $myemail;
}
