echo not printing variable

cool-palace-ceo

I have the following script

<?php
// Set Function To Show Correct Page On Input Of Correct Pasword
function amail_applet()
{
echo("$mailer");
return;
}

// Check To See That Password Is Correct
if($password==tehmux) {
amail_applet();
} else {
echo("You are not authorized to be here!");
}

// Protected Page HTML
$mailer = "
<head>
<title>Joel's A-Mailer</title>
</head>
<body bgcolor=#FF0000>
JOEL'S A-MAILER
<form method=POST action=sendmail.php>

";
?>

MY PROBLEM IS THE ECHO FROM THE FUNCTION AT THE TOP WON'T WORK. I TRIED DELETING EVERYTHING AT TOP DELT WITH AUTH AND JUST PUT echo($mailer); THAT WOULD NOT WORK EITHER!! WHAT IS WRONG?

3 things:
1. variables from outside functions are not available inside function unless they are called global
2. You don't need the parens nor the quotes

function amail_applet()
{
global $mailer;
echo $mailer;
return;
}

Why create a function that only echos one variable? Just echo it each time you need to see it.

that did not work. the variable is right there in the script. i am learning functions and that is why they are being used it is not necessary that they are used but i am using them. I could do this in place:

if(password!=ANYPASS) {
echo("You cannot view this area");
} else {
echo($mailer);
}

I am still calling to print the variable mailer on correct credentials and when the correct crendentials are supplied and it executes the echo the screen just goes white and nothing is displayed

your function calls a variable before it is created. you must define $mailer first then create the function and $mailer must be called GLOBAL within the function for it to work.

thanks for that info, if you could answer this really quick is there any way to use an echo to parse another php script such as

echo(blah.php);

Anon

include ('blah.php');

but i don't want to select functions or variables i actually want to redirect the system to parse everything between the <?php and ?> tags.
