Global variables

mikerh9

I need to have some variables that must be global. At the top of my file I declare the varables: global $temp;

Than in the function a need to request the variables, so I do the following:

I tried:
$var1 = GLOBALS['$temp']; and
$var1 = GLOBALS['temp']; and
$var1 = GLOBALS[$temp];

However the variable is empty, in other word the global declaration is incorrect. I also try to call $temp as regular parameter, but cannot access it. Any ideas what I'm doing wrong?

Thanks

$GLOBALS['temp']

You've missing the $, its an array.

$sender = $POST['email_sender'];
$receiver = $POST['email_receiver'];
$messageout = $GLOBALS['$redhat'];
if ($_POST) {
$To = $receiver;
$headers = "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=iso-8859-1\r\n";
$headers .= "From:"." "."$sender\r\n";
$About = $sender." "."Would Like to tell you!";
$welcome = "Your Friend"." ". $sender." ". $messageout ."words.";
$Data = $welcome;
mail($To, $About, $Data, $headers);
} }
?>

It works , but I have another question.

Function mail according to the PHP docs accpept just String input, and I'm passing integer. When I use redhat ='Redhat" it works but when I have an integer , it doesn't. Is there a way to fix that?

Thanks

It's called type casting. Convert it to a string.

$integer = 10;
$string = ( string ) $integer;

OR:

$integer = 10;
$string = "$integer";
