PHP Starter problems

After a period of use of various CMS's, I have begun to recognize the strength of being able to at least basic PHP. I have begun to look at some code that I threw up on my hosting to see what happens.

Now, however, I encountered the patrol, and I can not understand what is wrong. The code is extremely small and simple, like my PHP knowledge with other words.

The following code generates a "Parse error: syntax error, unexpected T_STRING in *******/ test.php on line 6".

PHP Code:

---

<?php 

$strang1 = This is; 
$strang2 = string; 
$strang3 = $strang1.$strang2; 
/* This will print: "This is a string"*/ 
echo $strang3; 

?>

---

What is wrong?

$strang1 = This is;
$strang2 = string;

You do not have " around the text?

<? php

$strang1 = "This is";
$strang2 = "a string";
$strang3 = $strang1.$strang2;
/* This will print: "This is a string" */
echo $strang3;

?>

Of course. Rookie mistake, so the whistle on that ;)

Thanks for the quick help!

However, one should be mindful of the difference between using:

<?PHP
$name = 'Erik';

// With easy fnuttar evaluated and given no value from $name, but printed as just $name

echo('Hello $name how are you?');

// Dock double fnuttar
echo("Hello $name how are you?");
// To print Hello Erik how are you? out.
?>

In other words. Have you no use to evaluate the variables in a string, so use simple fnuttar.
