Problem 1: <?Php$Variables = Variables ; $Mytext = <Myheredoc <Pre> This Is

Martha Raup 10/24/09 CIS 52a

Problem 1:
<?php$variables = "variables";
$myText = <myHereDoc
<pre>
This is some PHP text.
It is completely free.
I can use "double quotes"
and 'single quotes',
plus $variables too, which will
be properly converted to their values.
<b>Even <span style="color: red">HTML tags</span> work!</b>
And I can write myHereDoc, as long as it
is not alone on a line, like this:</pre>
myHereDoc;
echo $myText;
?>

*************************************************************
Problem 2:
<?php
function printBR($txt) {
echo $txt."<br />";
}
$myString = "Hi, welcome to my page!";
$myBoolean = true;
$myDouble = 4.234;
$myInteger = 3;
$myNull;
printBR("My string is: ".$myString.", and it's type is: ".gettype($myString));
printBR("My Boolean is: ".$myBoolean.", and it's type is: ".gettype($myBoolean));
printBR("My double is: ".$myDouble.", and it's type is: ".gettype($myDouble));
printBR("My integer is: ".$myInteger.", and it's type is: ".gettype($myInteger));
printBR("My null is: ".$nyNull.", and it's type is: ".gettype($myNull));
