Help with PHP? +REP!

ok, I am currently learning PHP on w3schools however I have entered what I want into a PHP file called index.php and opened in Mozilla Firefox

here's my code:

PHP Code:


<HTML>
<HEAD>
<title>PHP Test File</title>
<style type="text/css">
<!--
body {background: #6699cc;}
-->
</style>
</head>

<body>
<?php 
$txt="BLOB";

echo  $txt to you;?>


</body>
</html>

and here's the one on the w3schools:

PHP Code:


<html>
<body> <?php
$txt="Hello World";
echo $txt;
?> </body>
</html>

both of which when I open in Mozilla Firefox show nothing, what do I do?

could be because you have installed php on you pc. Its a server side language not client side so therefore needs to run on a machine with php installed..

Same thing that I said to him on MSN. I walked him through setting up and using EasyPHP, so he's good now

Just for reference to any other people who view this:

You need some kind of server software (e.g Apache with PHP or IIS with PHP) to run PHP scripts. The server parses the PHP and returns HTML to the browser (e.g Firefox/Internet Explorer). The browser does not actually parse/run the PHP.

Also, you can't echo a variable and string without quotes, it returns a parse error

PHP Code:


$txt="BLOB";

echo  $txt to you;

Should be either.

PHP Code:


$txt="BLOB to you";

echo  $txt;
# Or
$txt="BLOB";

echo  "{$txt} to you";

PHP Code:


<HTML>

<HEAD>

<title>PHP Test File</title>

<style type="text/css">

<!--

body {background: #6699cc;}

-->

</style>

</head>



<body>

<?

$txt = "BLOB";

echo  "$txt to you";

?>

</body>

</html>

And are you saving it as .php and not .htm/.html?

echo  "{$txt} to you";

Or even better idea:

Replace:

PHP Code:


 echo  "{$txt} to you";

With:

PHP Code:


  echo  '$txt to you';

I think he is saving it as .html

i find it cleaer just to seperate them more visually in code highlighting terms

PHP Code:


 echo  $txt." to you";

ps. Check the sourse, is the php actualy showing in the sourse code? if so you ether dont have php installed or are useing the wrong exstention
