Stringing Things Along

Why stop with numbers? PHP also allows you to add strings with the string concatenation operator, represented by a period (.). Take a look:

<?php

// set up some string variables
$a = 'the';
$b = 'games';
$c = 'begin';
$d = 'now';

// combine them using the concatenation operator www.phpsu.com
// this returns 'the games begin now<br />'
$statement = $a.' '.$b.' '.$c.' '.$d.'<br />';
print $statement;


As before, you can concatenate and assign simultaneously, as below:

<?php

// define string
$str = 'the';

// add and assign
$str .= 'n';

// str now contains "then"
echo $str;

?>

That's about it for this tutorial. You now know all about the basic building blocks and glue of PHP - its variables and operators. In Part Two of this series, I'll be using these fundamental concepts to demonstrate PHP's powerful form processing capabilities.
